Oatmeal Peanut Butter Bars

I’ve got the hubby craving what I’m craving apparently. He made this Creamy Peanut Butter Ice Cream the same day I made these Peanut Butter Oatmeal Bars with Peanut Butter Frosting. We are on peanut butter overload over here.

I spotted these bars over at A Hint Of Honey. They’re chewy and hearty – full of peanut butter and oats. The top is frosted with a thin layer of peanut butter frosting.ย  If you want more…go for it.

  • 1/2 cup sugar
  • 1/2 cup brown sugar
  • 1/2 cup peanut butter
  • 1/2 cup butter softened
  • 1 egg
  • 1 cup flour
  • 1/2 teaspoon baking soda
  • 1 cup old-fashioned oats
Peanut Butter Frosting:
  • 1/4 cup butter softened
  • 1/4 cup peanut butter
  • 1 teaspoon vanilla extract
  • 2-3 Tablespoons milk
  • 1 1/2 cups powdered sugar
  1. Preheat oven to 350 degrees F. In a large bowl cream the butter, peanut butter and sugars. Add the egg and mix well.
  2. Add the flour, baking soda, and oatmeal and mix until well combined. Press into a 9ร—13 baking dish sprayed lightly with cooking spray. Mixture will be wet.
  3. Bake for 12-15 minutes, or until the edges are golden brown. Remove from the oven and let cool completely before frosting.
  4. For the frosting: Combine the butter, peanut butter, and vanilla in a medium sized bowl and beat until fluffy. Add the powdered sugar and add the milk gradually until you reach the desired consistency. You may not need it all.
  5. Frost cooled bars. The frosting makes a thin layer for a thicker frosting you can double the frosting.

  4. I’m so glad you spotted these to share! These look so good!

  5. I pinned these to make with my boys this week. Thanks!

  6. Christy – these bars look delicious and are right up my alley because I swear, anything that has oats AND peanut butter falls into health food for me. Also, when you are you due (sorry, I’ve lost track!)??

      I’m due August 31st! So soon!!! Give me tips for 5 kids. You make it look easy…

      • Ha! That’s because you and I both know we can be very selective about what we post online. ๐Ÿ™‚ Most days I’m losing my mind. My husband keeps telling me once I learn to be patient and flexible, my life will get easier. Good luck to you! Wish I was there and I’d bring you loads of dinner and watch your kids. I’m sure my boys would love to pal around with yours (and Cam would love your little girl).

  12. These look amazingly good! Can’t go wrong with peanut butter. I want some for breakfast, the oats in them would make that ok right :)?

  13. Is it possible to use almond butter in place of the peanut butter?

  14. These look great! Can’t wait to try them!

  15. Oh wow! I made these with coconut oil, gf oats and Pamela’s baking mix to make them gluten free/casein free and they are amazing! Also whipped up a chocolate/coconut oil icing for the topping. I really wish I could have figured out how to make them calorie free too ๐Ÿ™‚
