Peanut Butter Chocolate Bars

These Peanut Butter Chocolate Bars have layers of buttery cake mix and a coconut chocolate creamy filling.

Peanut Butter, chocolate, cake mix…how could this not be heaven. I have been making these for a couple years ever since I had them at my friend’s chocolate party. This are very, very rich. For me to say that is saying a lot. They are perfect for a PMS moment. Not that I have had any of those for 5 months. They are probably 10,845 Weight Watcher points! Decadent.

Speak Your Mind



  1. I had no idea a recipe from me would be here. I remember the chocolate party well, and I remember giving you the recipe. Julie Mecham just told me about your website and I LOVE it!!! This is a fun site and I feel like we’re chatting and eating at the same time while I read your fun and personal intros.
    I see you’re inspiring nature hasn’t changed. Your values come through your thoughts and I love it!

    • Just wondering, are you the same Greta White who used to teach Kindergarten in Columbia, MD? If so, I was your student teacher one year and would love to chat with you.

  2. Oh my. I found the picture of these on Pinterest and had to try them. So good.

  3. These look Yummy!

  4. Just made this. It was delicious. Thanks so much for the recipe.

  5. I also saw this on pinterest, but have been following you for a long time. With all of those pins I see, I am so surprised that there aren’t a million comments on these. Just whipped up a batch and they are fantastic!

  6. This looks like a great recipe!

  7. I like many others found this on pinterest about 28 minutes ago and it is now coming out of my oven for a potluck in 19 minutes! Thanks for a delicious recipe!

  8. Oh my GOSH – Found these on pinterest and I will FOR SURE be making these this week – we have company coming for my brothers wedding (and PMS will be in full swing! ha!)

  9. I am going to make these today. These look soooooo good!
    I kinda want to try them with Nutella!

  10. I’m in Canada…how much is one stick of butter? We have our butter and margerine in bricks. ๐Ÿ™‚

  11. These look fabulous! Thanks for sharing.

  12. Ok, I think I’m in trouble. I made these today and was going to take them into work. I tried them first, which was my mistake. Now I’m not sure they will make it to work tomorrow before I eat them all. HELP.

    Very delicious, thank you for sharing the recipe!

  13. @Jaymie,
    Haha! Sorry. Over here, 1 stick is a 1/2 cup of butter.

  14. Has anyone made this with milk chocolate chips instead of semi-sweet? I wonder if that would be ok…..this sounds delish! Can’t wait to bake this ๐Ÿ™‚

  15. I made these the other day and everyone seriously keep on telling me how much they loved it. Cheap and Delicious

  16. I entered in the information to weight watchers, and the whole batch is 186 points plus. Not sure how many bars this makes, but even cutting into 36 pieces, it’s still 5 points plus per bar. 36 pieces!!I have a feeling I could not just stop at one.

    Do they freeze?

  17. I found your recipe on Pinterest. My hubby and I had your Peanut Butter Chocolate Bars for dessert last night. After reading your comment about the coconut, we decided to make one side (one half) of the pan with no coconut and the other side with coconut. Instead of mixing it into the melted chocolate chips and condensed milk, we chose to put sprinkle it on top of the layer of chocolate on one side of the pan, and then crumb the reserved 1.5 c peanut butter on top of it all. It is very delicious either way. Thanks for sharing!

  18. I am making these today with a chocolate cake mix with added Reese’s Peanut Butter Chips!

  19. Aww man. I REALLY want to make these! When I saw them on your 2010 recap page, I told my husband that I would definitely make them today but then I saw that they have cake mix. I don’t have anything against cake mix but we don’t have it here in Germany. I’ll have to find a good cake mix recipe!

    These are the most delicious looking peanut butter bars ever. Happy New Year to you!

  20. I couldn’t stand it any longer. I found a recipe for cake mix, made the cake mix and then made these. They’re so yummy! And surprisingly simple! I think the cake mix was a little off because my peanut butter mixture was just too dry, so I’ll try making more cake mix with less flour. Thanks for the recipe! ๐Ÿ™‚

  21. I made these after church a couple of Sundays ago, and they are GOOD. I absolutely loved them. Very savory and sweet! Thank you for sharing!

  22. Found you on Pinterest! Can’t wait to make these! Cute Blog!

  23. saw this posted on Pinterest earlier this week and haven’t been able to stop thinking about it. finally after a very disappointing delivery dinner i decided that i needed an amazing and mouthwatering desert. so i got all bundled up and went to the store to get all the ingredients i didn’t have and it is in the oven RIGHT NOW!!! i can’t wait to put them in my mouth!!!!!

  24. stopping over from pinterest – I had all the ingredients in my pantry and some impromptu visitors. Mine are in the oven right now!

  25. So I just pulled these out of the oven, and I don’t know how you can wait for them to cool before you dig in. From my little, itty bitty experience, may I say that if you sniggle a bite with a spoon, you WILL burn the inside of your sweet little mouth and it hurts, a lot. So worth it!!! YUM

  26. I found this on pintrest and made them for work. Everyone loved them!

  27. Anyone ever make these with milk chocolate instead of semi-sweet? I am thinking about trying it.

  28. Oh my goodness, I made these to use up an old cake mix and they were amazing! I took them to work and they went crazy for them. Thank you!

  29. I just found your site via Pinterest and wondered if you would share with me how you are adding the option to print your recipes. Do you mind emailing me?

  30. I am making these, they’re in the oven. BUT I didn’t have Yellow Cake Mix or Choc. Chips, so I used a Choc. cake mix and White Choc. chips! Hopefully the reverse will be as soon as the original!!!

  31. Found this recipe on Pinterest – and we’re cooking it right now! Didn’t have the chocolate chips so subbed peanut butter-chocolate swirl morsels….it smells so good! Thank you for sharing!!

  32. wow these look amazing! going to make these for a new mom – she totally can use the extra calories ๐Ÿ˜€ i don’t have enough butter – will make with applesauce. should be okay i hope!!

  33. Found these on pinterest a while ago and have been trying to restrain myself from making them. Well PMS is in full swing AND I had all of the ingredients. So yeah, they are in the oven. My pb mixture didn’t seem crumbly per se so I added a few oats to the 1.5 cup topping mixture. We’ll see how they turn out, and now with oats they are like granola bars right? Health food!? ๐Ÿ˜‰

  34. @jillie.bean,
    The topping texture shouldn’t be crumby. You’re supposed to “crumble” or just dot pieces of the dough on top. But your version sounds great!

  35. @jillie.bean,
    The topping texture shouldn’t be crumby. You’re supposed to “crumble” or just dot pieces of the dough on top. But your version sounds great!

  36. Shouldn’t these come with a “check with your cardiologist first” warning? They look like pure evil! (And evil is good!)

  37. Wow these sound delicious and want to make them now! I wish I had some yellow cake in my house right now ๐Ÿ™ That’s the only thing I’m missing!

  38. Mine is more like cake and the chocolate mixture sunk to the bottom. Yours looked more like hardened bars in the picture not cake…any suggestions? Do I need to cool the chocolate mixture completely before putting it on the peanut butter/cake mix layer?

  39. @Cara,
    It’s definitely not the texture of cake – it’s way more dense. I’m not sure why your chocolate mixture sunk. You shouldn’t have to cool it all the way but it shouldn’t be piping hot.

  40. how do i know when it’s done? is it supposed to be jiggly when it comes out, or do they harden upon standomg?

  41. @Anonymous,
    They might be a little jiggly when they come out. The cake on top should be slightly brown which is when you should pull them out. They will set up when they cool. They do take a while to cool.

  42. Made this tonight for hubby but added chopped peanuts to the cake mix and a lil ground up flax seed…and guess what he loved it!!! I gotta sneak something healthy in…lol

  43. I made these today to take to a party. Of course, I need to sample them before I took them just to be sure they were ok. They were YUMMY!!! I was a little worried since the peanut butter batter was very greasy and was not really a texture you could crumble. I just made dollops on top of the chocolate layer. I also cooked it about 3 to 4 minutes longer than recommended. It turned out GREAT!!! I would definitely make this again. Thanks for a great and easy recipe.

  44. Has anyone tried these in a jelly roll pan (11×17)?

  45. Mmmm! I just went to the grocery store and got all the ingredients to make this tonight. CAN’T WAIT! Thanks for a great and easy recipe!

  46. These came out great! Used greek yogurt in place of the butter. Next time I probably won’t use sweetened condensed milk. It’s very sweet and super rich. Instead, I’ll use vanilla almond milk. FIve stars!

  47. Wow! I made these today and I must say they are delicious! They are a little rich but that’s okay. :)Everyone that tried them really liked them too. Will definitely make again. ๐Ÿ™‚

  48. Has anyone actually used nutella instead of chocolate chips/condensed milk?

  49. Found this on pinterst! Making this today! Great treat before having my wisdom teeth surgically removed.

  50. This must be heaven! Thanks for sharing!

  51. Can this be made without sweetened condensed milk? Could I use regular milk instead?

  52. @Mvad,
    I think regular milk would make the center way too thin and runny…

  53. Found your recipe via pinterest. It’s a winner – thanks for sharing!!!

  54. Lots of comments for this wonderfull receipe!
    It looks so delicious!
    Thanks for the receipe and see you

  55. i think the commebt about the chic sinking to the bottom prepared tge cake mix. The cookie crust is just cake mix dry eggs and peanut butter.
    Found you through pinterest and these are in the oven now! can’t wait.

  56. i saw your recipe on pinterest. it look really tasteful.!!!! but one question:what is the yellow cake mix???? is there any other name to find it at the super market……. if yes please let me know

  57. I made these last night after seeing them on Pintrest, and wowzers!! This recipe is genius! How can you go wrong with chocolate, sweetened condensed milk, yellow cake mix, and peanut butter!! Awesome stuff!

  58. Andrea Jimenez says:

    Made these three times in the last week. I first made it for a co-workers birthday then for another co-worker that wanted to take them home. Today, I brought some in to share with the rest of my office co-workers. I didn’t add the coconut but they were still good.

  59. Made these tonight and yum yum are they ever good! Thanks for sharing this recipe!

  60. Thank you soooo much for this recipe! It has become me and my girlfriend’s absolute favorite! It couldn’t possibly be more delicious!!!!

  61. Made these for my holiday party and they were a hit! Plus they were super easy and I had all the ingredients in the house. Seems like these will be the perfect go-to dessert when I need a quick treat for unexpected events!

  62. DELICIOUS!!!! thank you for sharing this wonderful recipe!

  63. love the idea of peanut butter cookies. I made a batch of my peanut butter and have so much i can’t just put it all on toast so looking forward to making some cookies with it. thanks

  64. These bars are absolutely delicious!!! My daughter gave them the highest compliment–she said they are tied with macaroni and cheese for her favorite food (and this girl would eat macaroni for EVERY meal, if I let her). Thanks for the great recipe! P.S. Left out the coconut, too.

  65. I am in the process of making these for dinner at my parents, it was so easy! They look and smell amazing and I can’t wait to try them! Foud the recipe on Pintrest, thank you so much ๐Ÿ™‚

  66. What if I don’t have sweetened condensed milk? Anyone know what I can use as a substitution?

    • Christy {The Girl Who Ate Everything} says:

      I personally don’t think there’s any substitute with the same consistency. I’ll keep thinking…

  67. Made this for my husbands birthday. Only one of the eight people invited liked it.
    It is very sweet. Too sweet. Dense and like eating raw peanut butter dough. We are giving the rest away. Sorry, not our thing.

  68. Hi, im from South Africa, and I have no idea what yellow cake mix is? Please help!

  69. I just made these with some modifications. My yellow cake mix was only 15 oz. so I subtracted the 2 tbsp of butter from the stick of butter added to the cake mix. I also used 1/2 cup crunchy peanut butter because I ran out of the smooth. My dough didn’t seem thick enough so I added 1/4 c almond flour before pressing into the pan. I then added another 1/4 c. Almond flour for the topping to make it more crumbly. For the chocolate I used fat free sweetened condensed milk. These turned out great. I will make them again soon.

  70. Stacey Thompson says:

    I am so excited to try these! I have everything but the creamy peanut butter. Does Chunky Peanut Butter work?

    Thanks for the recipe!

  71. these sound delish! but is there anything that could be subitstuted for the peanut butter? yogurt maybe?

  72. Has anyone tried this with white cake mix? I don’t have any yellow cake mix.

  73. I put in 1 cup of butter instead of 1/2 help what should I do!!

  74. I put in 1 cup of bitter instead of 1/2 help what do i do!!

  75. These are in my oven right now…1 am!! I forgot I had to bring a dessert to a family gathering tomorrow…I didn’t have a yellow cake mix, so I’m trying them with a German chocolate cake mix and milk chocolate chips since that’s what I had in the pantry. I also added a few vanilla candy melts to equal the chip amt needed. I tasted the spoon after pouring it on the base layer and it reminded me of a Cadbury egg!! : ) Cannot wait to taste them later today!!

  76. Add me to the Pinterest group, as well. They’re about to come out of the oven! They look awesome!

  77. Joanie Dittman-Guthrie says:

    Hi just put hese in the oven!!! cantwait to try them ๐Ÿ™‚

  78. Can you use unsalted butter!!!?!

  79. these look too good to be true! trying tomorrow, thanks!

  80. I love this recipe! I have made them several times and they are always a huge hit ๐Ÿ™‚ They are also really easy to make. Thanks for posting such a great dessert!

  81. I too found this on Pinterest and am thrilled with the results! I put a twist on the recipe by using a banana cake mix so mine is peanut butter chocolate banana bars. I was going to take them to work tomorrow but my husband has threatened me if I even think about taking more than one – for my lunch – out the door! I need to get one more good picture of a cut piece, probably tomorrow morning and then I will make a post so I will link back to you as the originator, you will probably see a ping back tomorrow evening! I thank you and my husband thanks you too – oh yes, and Greta!

  82. What if my cake mix is only 15.25 oz? Can I add more flour or do I not add anything extra?

  83. I wanna make these for a big anniversary party for my Mom and Dad… but I am wondering if they freeze well? Do you know!!!

  84. Briana Kramer says:

    I really really want to try these but I don’t like Coconut at all!!
    Do I have to use them and if I do is the coconut flavor strong?

    • Christy {The Girl Who Ate Everything} says:

      The coconut flavor is not strong but you can definitely leave out the coconut and they will still be good!

  85. Made these today and they were super yummy! Tastes like chocolate chip cookie cake! I didn’t have sweetened condensed milk – I only had evaporated milk, but I googled how to convert that and it worked well enough. My husband ate a lot of it ๐Ÿ™‚ Thanks!

  86. Found these on Pinterest and made them tonight. So completely delicious! Thanks for sharing.

  87. I made these today for my neighborhood picnic. Everyone RAVED about how great these were. 4 request for the recipe. Thanks for sharing and I think I’m on the hook for making these for future gatherings.

    I’m thinking about swapping out the chocolate chips for nutella. what do you think?

    Thanks again for this recipe…

  88. Can you substitute a different nut butter? My son is allergic to peanuts and is not big on Nutella. I was thinking of using Sunflower seed butter? Can’t wait to make them. I will let you know how they turn out.

  89. Made these today and they are to die for! They taste like peanut butter cookies with melted chocolate in the middle. Everyone loved them!

  90. I made these for our neighborhood potluck. Huge hit! I loved how soft they were.Thanks for the recipe!!

  91. I’ve been making these bars for over thirty years, but the original recipe called for a box of coconut pecan frosting mix added to the chocolate mixture, which they don’t make any more, so it is interesting to see the adaptation of adding coconut. I have just been making it w/o the box of frosting and left it like that. It turns out fine. I do use milk chocolate rather than semi-sweet chips though. I tried it with semi-sweet and we like the milk chocolate much better.

  92. In Love with this recipe says:

    I did this recipe for my mom’s 43rd birthday. However instead of vanilla cake, I used chocolate devils food cake. It turned out GREAT! Thanks for the idea! Please keep them coming! It was AMAZING!

  93. HOLY CRAP this are AMAZING!!!! Made these the other night for a MaryKay party and AHHH LOVE!!!

  94. So annoyed that I forgot to stir in the vanilla. They are in the oven now so crossing my fingers! Think I will be ok?

  95. I just made a pan and added a few chopped pecans instead of coconut… Hope they turn out good!

  96. The recipe sounds wonderful and I can’t wait to make it tonight. The comment of the person that had the layer fall to the bottom; well there may be a difference in the consistency of the peanut butter . Let me know your thoughts as I made two different items for the holidays and I had jiff peanut butter and both recipes flopped. But I re made these with either Reece’s or Peter Pan peanut butter an had complete success. ( my jiff may have been old . ) anyway I’m using Peter Pan today. Thanks love your web page.

  97. Andrea Jorgensen says:

    Wait….chocolate party???!!! Why have I never heard of such a thing?? Trying these for a party tomorrow. I love your blog!! It is my GO TO for recipes of every kind. Thanks for doing what you do!! ๐Ÿ™‚

  98. I busted this out last night for a work potluck we are having. Super easy to follow along! I was surprised they were not sweeter.. or my taste buds are just weird to start ๐Ÿ™‚

  99. What happens if you forget vanilla in the chocolate. Made these at 5 this morning….guess I wasn’t quite awake!!

  100. Delicious and easy! I used fat free sweetened condensed milk and no coconut. I used creamy peanut butter but I think I’ll use chunky next time.

    • I made these twice in one week, and interestingly came out pretty different — both delicious but different textures.
      Both times I used FF sweetened condensed milk. I forget if the butter was salted or not.
      The first time I used Pillsbury yellow cake mix, and regular creamy peanut butter.
      The second time I used Duncan Hines golden butter cake mix, and reduced fat creamy peanut butter.
      I think the texture was better the second time, so I’ll make a mental note to use Duncan Hines again.

  101. This is my husband’s new favorite dessert! I just make it again last night for his birthday.

  102. Amazing! I even forgot to add the vanilla, still amazing. These will definitely be added to my easy, need something quick list!

  103. So we r making this reciepe andy daughter put the melted butter in the cake mix no what to do??? Please help

  104. So we r making this reciepe andy daughter put the melted butter in the cake mix no what to do??? Please help

  105. I added melted butter to cake mix. Somebody help what do i do now

    • Christy {The Girl Who Ate Everything} says:

      Keep going. Add the peanut butter and eggs like in the instructions and press into a 9×13 baking dish.

  106. Wow looks delicious thx for sharing!! I have a question about the recipe…It says reserve some mixture to crumble on top…so as it is raw batter, do you mean pour the raw batter onto the top? Can you pls clarify thank you so much! Not sure how you crumble the batter?

  107. These sound delicious! I wonder how they would come out if you used 1/2 butter and 1/2 coconut oil, to get the coconut taste but not the texture some may not like.

    I just might have to try it ๐Ÿ™‚

  108. Does anyone know if I should use salted or unsalted butter for the best taste?

  109. I made this tonight. It’s very rich but we really liked it.
