Fudgy Peanut Butter Chip Brownies with Dark Chocolate Frosting Posted on 9 Aug 11:36 , 0 comments

This brownie recipe, created by Sweet Things by Lizzie, creates moist and rich brownies with the salty balance of the peanut butter chips. Then she adds a dark chocolate frosting for a deeply intense chocolate flavor to put these brownies on a whole different level compared to other recipes.


  • 10 tablespoons unsalted butter
  • 2 room temperature eggs
  • 3/4 teaspoon salt
  • 2 cups white sugar
  • 1 and 1/3 cups all purpose flour
  • 3/4 cup best quality cocoa powder
  • 1 teaspoon best quality vanilla
  • 1/2 cup water
  • 2 and 1/2 cups peanut butter chips

Dark chocolate frosting

  • 3/4 cup best quality dark chocolate
  • 1/2 cup plus 2 tablespoons heavy cream or half and half
  • 2 tablespoons softened butter
  • 1 and 1/2 to 1 and 3/4 cups powdered sugar
  • pinch of salt
  • 1 teaspoon best quality vanilla


  • Preheat your oven to 350 degrees
  • Lightly butter a 13×9 inch baking pan and line with parchment paper
  • Melt butter and cocoa in a microwave safe bowl for about 45 seconds to one minute.  Whisk together to combine until  the lumps are gone.  Let cool and transfer to a mixing bowl
  • To the cocoa mixture, add eggs, sugar, vanilla and water and whisk by hand until combined
  • Add the flour, baking soda and salt and blend until just combined without over mixing
  • Add in peanut butter chips and stir until evenly distributed
  • Spread into your prepared pan with an offset spatula
  • Bake for 15 minutes then rotate the pan in the oven.  Bake another 10 to 15 minutes or until the center of the brownie seems set but not over baked
  • Let cool completely while you prepare the frosting
  • To make the frosting, melt the chocolate and butter in the microwave until just combined
  • Transfer to a mixing bowl with a whisk attachment.  Slowly add the cream, vanilla and powdered sugar until you have a smooth spreadable consistency.  Add a pinch of salt if you prefer to offset the sweetness.  You can add more or less cream depending on how thick or creamy you like your frosting
  • Spread the icing over the completely cooled brownies
  • Chill the brownies in the fridge for about 30 minutes before cutting
  • Lift the brownies out of the pan holding onto the parchment.  This makes for less clean up and no brownies sticking to the pan too!!

Makes 30 brownies.  Prep time: 30 minutes  Bake time: 25-30 minutes
