  • 1 18.25 package plain yellow cake mix
  • 1/2 cup butter melted
  • 1 cup creamy peanut butter I used crunchy- it was amazing
  • 2 eggs
  • 1 12 oz package semi-sweet chocolate chips
  • 1 14 ounce can sweetened condensed milk
  • 2 Tablespoons butter
  • 2 teaspoons vanilla


  • 1. Preheat oven to 325 degrees. Set aside an ungreased 9X13 inch metal pan.
  • 2. Stir and combine cake mix, melted butter, peanut butter, and eggs in a large bowl using an electric mixer or a wooden spoon. The batter will be thick. Press this into the pan, reserving 1 1/2 cup of the mixture to crumble on top.
  • 3. In a small pot, melt chocolate chips, sweetened condensed milk, and butter. Remove from heat and stir in the vanilla.
  • 4. Spread chocolate mixture over the cookie crust in the pan, and then crumble the 1 1/2 cups of reserved cake mixture on top evenly.
  • 5. Bake for 20-25 minutes. Cool completely before cutting into bars.
  • These cookie bars are amazing when eaten warm, but are just as good cooled. Serve with a tall glass of milk, and enjoy. You know you want one!
