Peanut Butter Brookies from Dessert Mash-Ups

Author: Lisa Longley


  • 1 cup creamy peanut butter
  • 1/2 cup granulated sugar
  • 1/2 cup packed brown sugar
  • 1 egg
  • 4 ounces of milk chocolate morsels see note
  • 3/4 cup unsalted butter
  • 1 3/4 cup granulated sugar
  • 3 eggs
  • 1 TBSP vanilla extract
  • 1 cup all purpose flour


  • Preheat your oven to 350 degrees. Spray a 9 by 13 inch pan with cooking spray.
  • In a large bowl, stir the peanut butter, sugars, and egg together. Press it into the bottom of the pan. It will be a thin layer. (Dorothy suggests using cooking spray on your hands to make for easy spreading of this layer.)
  • Melt the chocolate and the butter together in a large microwave safe bowl in 30 second intervals, stirring between each one, until it is one smooth mixture.
  • Stir the eggs, sugar, and vanilla into the chocolate butter mixture until smooth. Then gently stir in to the flour.
  • Pour the batter over the peanut butter layer and bake for 32 to 38 minutes or until the edges are slightly cracked. Let it cool in the pan completely before cutting and serving.


Dorothy's original recipe calles for 2 ounces of unsweetened baking chocolate, coarsely chopped and 2 ounces of semisweet baking chocolate, coarsely chopped. Since I had all the other ingredients on hand, I used 4 oz of milk chocolate, and it was fantastic!
