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. If you want more…go for it.

Oatmeal Peanut Butter Bars

These oatmeal peanut butter bars bake up quickly, and then you top them with a quick peanut butter icing.


  • 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 9×13 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.
For the frosting:
  1. 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.

  2. Frost cooled bars. The frosting makes a thin layer for a thicker frosting you can double the frosting.
