Ingredients

Peanut Butter cookie Layer

  • 1/2 cup salted butter
  • 1 cup peanut butter
  • 1/2 cup granulated sugar
  • 1/2 cup brown sugar
  • 2 eggs
  • 2 tsp vanilla
  • 1 1/2 cups all purpose flour
  • 1 cup old fashioned oats
  • 1/2 tsp salt
  • 1 tsp baking soda

Chocolate Icing

  • 1/2 cup salted butter
  • 4 tbsp cocoa powder
  • 6 tbsp milk
  • 1 lb powdered sugar
  • 1 tsp vanilla

Instructions

  • Preheat oven to 350°.
  • Cream together butter, peanut butter and sugars until light and fluffy with either a stand mixer or electric hand mixer.
  • Add in the eggs and vanilla, mix until just combined.Add in the flour, old fashioned oats, salt and baking soda.
  • Mix until the cookie dough forms. Dough will be slightly sticky.
  • Spread and press the dough into the bottom of a greased 9x13 pan.
  • Bake at 350° for 18-20 minutes.
  • Once the peanut butter bars come out of the oven, make the frosting.
  • To make the frosting, melt the butter, cocoa powder and milk in a medium saucepan pan over medium heat. Bring to a soft boil.
  • Once boiling, remove from heat and whisk in the powdered sugar and vanilla.
  • Let the icing cool for 10 minutes. Stir the icing to break up the crusting on top and then pour over the peanut butter bars.
  • Allow to cool completely before cutting. (can put in fridge to speed up the process if desired.)
