Peanut Butter Truffle Brownies #recipe from @KatrinasKitchen at

Many of you commented and sent emails that you would like to see the Tag-a-Long Girl Scout cookie next. Let’s just say they are in the research stage right now…to be continued! For now you will have to suffer through these Peanut Butter Truffle Brownies.

Poor you!

I don’t know what it is about these but aren’t you compelled to go make them? I was hooked the moment I saw the picture. It’s essentially a homemade brownie slathered with heaven-in-peanut-butter-form then topped off with some chocolate love. Few of us could say no to such a delightful little treat.

I hope you enjoy these as much as my family did! Four Year Old Foodie was so delighted with them that he HAD to have a naked slice warm out of the oven. I told him that would result in not having a slice later when it was topped off but he has the patience of a preschooler. Go figure. Enjoy!

  • For the Brownies:
  • 1 cup butter
  • 2 cups sugar
  • 3 eggs
  • 3 teaspoons vanilla
  • 2/3 cup cocoa powder
  • 1 cup flour
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking powder
  • For the Peanut Butter Filling:
  • 1/2 cup butter, softened
  • 1/2 cup peanut butter
  • 2 cups powdered sugar
  • 1-3 teaspoons milk
  • For the Ganache Topping:
  • 1/4 cup peanut butter
  • 2 cups chocolate chips
  • 1/4 cup butter
  • 2 tablespoons heavy whipping cream


  • Preheat oven to 350F. Butter the bottom and sides of a 9 by 13 inch metal baking pan. Put a long piece of parchment paper in the bottom of the pan, letting the parchment extend up two sides of the pan and overhang slightly on both ends. (This will make it easy to remove the bars from the pan after they have baked.) Butter the parchment.
  • In a medium saucepan over medium heat, melt the butter. Remove from heat and add the sugar; stir to combine. Beat in eggs and vanilla until combined. Mix in cocoa, baking powder and salt. Add flour and stir until just combined and no streaks of dry ingredients remain. Pour into prepared pan and spread into an even layer. Bake for bake 25-30 minutes. Let cool completely in pan on a cooling rack.
  • While the brownies are cooling, make the peanut butter filling. In the bowl of a stand mixer fitted with the paddle attachment, combine the ingredients and beat until smooth. Add more milk if necessary to make it spreadable. Spread in an even layer over the brownies. Place in the refrigerator until filling is set, about 30 minutes.
  • While the filling is setting, make the ganache, combine the ingredients in a double boiler or in a microwave safe bowl. Melt together and combine. Pour the ganache over the top and spread gently. Return to the fridge until set.
