As a child, I remember my mom making something similar to these cookie bars, but I didn’t have a full fledged recipe. So I pieced together two separate recipes, and the result was just like I remembered those yummy bar cookies.

It’s three layers: the bottom which is like a giant oatmeal peanut butter cookie, then a layer of chocolate, and it’s topped with homemade peanut butter frosting. Yum!

Then mix dry ingredients together:
  • 1 cup flour
  • 1/2 cup quick cook oats
  • 1 teaspoon baking soda
  • 1/4 teaspoon salt
 Combine wet and dry ingredients and spread in a 9×13 inch greased pan.

Bake at 350 degrees for 20 to 25 minutes.

After they start to melt, spread them over the top with a spatula.

While this cools and the chocolate hardens up, make the peanut butter frosting.

Peanut Butter Frosting:

  • 1/2 cup plus 1 Tablespoon room temperature butter
  • 1 cup creamy peanut butter
  • 1/4 cup milk, add more if too thick
  • 2 cups powdered sugar

Beat peanut butter and butter with mixer, then gradually add powdered sugar and milk alternately.
Beat well, till it is fluffy. If it is too thick, try adding a dab more milk.
Spread over the cooled chocolate layer.

Let them sit for a few minutes at least so everything “sets” and then you are ready to cut into bars and serve.
