I’m a huge fan of all things Monster. Monster Cookie Dough Dip and Monster Magic Cookie Bars are a couple of my favorites. I’ve been craving Monster Cookies for a while but after browsing Pinterest I didn’t find any that I really wanted to try so I thought I would develop my ownI knew what I wanted in a Monster Cookie. I wanted a soft cookie packed with peanut butter flavor, chocolate chips, M&Ms, and oats. I learned from my Oatmeal Raisin Cookies that less oats actually makes for a chewier cookie. Although I have had several fails, this my friends…was a success.

Monster Cookies
 
Serves: Makes around 30 cookies
Ingredients
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • ¾ cup (1½ sticks) unsalted butter, slightly softened
  • 1 cup brown sugar
  • ½ cup granulated sugar
  • ½ cup creamy peanut butter (use crunchy if you like nuts)
  • 1 whole egg
  • 1 egg yolk
  • 1 teaspoon vanilla
  • 1½ cups old fashioned oats
  • 1 cup peanut butter chips
  • ¾ cup semi-sweet chocolate chips
  • ¾ cup M&Ms
Instructions
  1. Preheat oven to 350 degrees and line a cookie sheet with parchment paper.
  2. In a medium bowl, whisk together the flour, baking soda, and salt.
  3. In a large mixing bowl, cream together the butter, brown sugar, white sugar, and peanut butter.
  4. Add the egg, egg yolk, and vanilla and mix well until creamy.
  5. Slowly add the flour mixture until incorporated. Mix in the oats.
  6. Stir in the peanut butter chips, chocolate chips, and M&Ms. You can use a mixer (if you're lazy like me) or stir in by hand. Stirring in by hand makes sure that the M&Ms don't break.
  7. Place balls of dough, around 1½ Tablespoons each, on the parchment sheet. You can hand place extra M&Ms on top, pressing slightly in, to give the cookies a professional look.
  8. Bake for 9-11 minutes. Make sure not to overbake. The cookies will not be brown and will continue to cook as they cool on the pan.
  9. Store in an airtight container. Makes around 2½ dozen.

  1. My 5yo wanted to tell you that they aren’t Monster Cookies because they aren’t made from monsters …. I swear, they don’t make kids like they used to. When I was 5, I was excited just to be allowed to EAT the cookies.

  2. These look DELICIOUS! Will be putting them on my ‘to bake’ list! x

  3. Ahh, this cookies seem to be so lovely! Definitely gonna try this.

  4. Great minds think alike! I just made monster cookies last night 🙂 Why are they so darn good?!

  5. My favorite kind of cookie!! I’ll have to try your recipe out as I have not found the perfect one yet.

  6. These look awesome! I’ve never had a monster cookie!

  7. the dough looks amazing!!! love these! I’m pinning the recipe and making them as soon as possible!

  8. THese look so yummy! Pinned!

  9. I made these today. These seriously are the best cookies I’ve ever ate. They look and taste amazing and her recipe directions are perfect recipe! Thanks Christy for all you do!!!

  10. my turning 5yo requested these for her birthday dessert, and her 3yo sister tells everyone, “we’re having monster cookies – RAWR! but don’t worry. they’re not scary.” and i’ll add that they’re delicious!

  11. I saw this recipe on Pinterest and pinned it. Today is a snow day in northeast Alabama and I just had to make them! They were a hit! I halved the recipe bc we are on a diet! Ha!

  12. Had a snow day today and made these cookies. They are awesome!!!! Never had a monster cookie until today…. delish!

  13. Just made these today. They’re amazing! Thank you so much for sharing the recipe!!

  14. I regret to say that alas, these are not Monster cookies. Not the Amish loved cookies of my youth; but they are nice cookies. These created a cake like cookie. They lacked the slight snap of the Mennonite cookie I know so well. Two things: I used all natural peanut butter. But that would result in a dryer cookie (mine was crumbly). My suspicion is that the omission of corn syrup (and why I chose your recipe in the first place) is the component. The batter just lacked a certain sine quod non. We did enjoy the cookies very much. my toddler had fun extracting the candy peices from his cookies -with a spoon no less. I future I think I will try to use maple syrup to mimic that chewy snap.

  15. i just made these. Oh, my gosh. Absolutely delicious and so much better than the monster cookie recipe I’ve been using. Thank you for a recipe that actually delivers! I am new to your website and look forward to trying more stuff!

  16. I made these cookies yesterday and they turned out great! Definitely one I will be making again! …Sharing this recipe with a friend 🙂

  17. They look great!!! I want to make them now!! question I like my cookies crisp, do I need to add more oats, could you give me an advise! Thanks!!!

  18. Question–it says 3/4 cup of butter, but then 1 1/2 sticks in parenthesis. Which is it? 1.5 sticks would be 1.5 cups…help! Best recipe I’ve found and want to make today!

  19. I made these yesterday and brought them to work, my coworkers went crazy for them! Amazing recipe! Your recipes never let me down! Thanks =)

  20. I’ve made these cookies a couple times now and I love them! They are preyy easy and they’re always a big hit! I’ve also used dark chocolate M&Ms in them, which is a fun mix up 🙂 Thanks for shaing your recipe!…I’ve enjoyed it 🙂

  21. I am so thankful for you and your recipe 🙂 I cannot make cookies. Really. They turn into flattened hard blobs every time, when my friends use the same recipe they come out amazing, but not me. I have no idea what’s wrong with me! I actually bake a lot and have lots of success with other things, just not cookies for some reason. After a while I gave up and refused to try making cookies anymore. My distraught husband made these cookies and they’re DELICIOUS! perfectly soft, but crispy on the edges, filled with yummy ingredients. We love them! So thank you for bringing cookies back into our lives. It would be a sad live that was cookie-less!

  22. Looks so good

  23. These are Awesome! My grandson loves my mini monsters

  24. These cookies were amazing! but I need some help, I’m trying organic peanut butter for the first time and while by peanut butter cookies came out wonderful using organic these cookies came out really dry and crumbly. They were still good (my hubby can’t stop eating them lol) but how do I make them more creamy? Just use more peanut butter? Thanks.
