Ingredients
  

Brownies

  • 1 (18-ounce) box fudge brownie mix + ingredients listed on the box

Peanut Butter Frosting

  • 1 cup creamy no-stir peanut butter
  • 1/2 cup unsalted butter room temperature
  • 2 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • 2–4 tablespoons milk

Chocolate Ganache

  • 1 cup semi-sweet chocolate chips
  • 1/3 cup heavy cream

Instructions
 

  • Preheat the oven according to the brownie mix instructions. Line a 9x9-inch baking pan with parchment paper.
  • Prepare the brownie batter as directed on the box, pour it into the prepared pan, and bake as instructed. Let the brownies cool completely.
  • In a mixing bowl, beat together the peanut butter and butter until smooth. Mix in the powdered sugar, vanilla, and salt. Add milk, one tablespoon at a time, until the frosting is smooth and spreadable.
  • Spread the peanut butter frosting evenly over the cooled brownies. Refrigerate for at least 20 minutes.
  • Place the chocolate chips in a microwave-safe bowl. Pour the heavy cream over the chocolate chips and microwave for 40 seconds. Let sit for 1 minute, then whisk until smooth.
  • Pour the ganache over the peanut butter layer and spread evenly. Refrigerate until set.
  • Slice into squares and serve.

Notes

  • Store the brownies in an airtight container at room temperature for 2-3 days or in the refrigerator for up to 5 days.
  • Freeze the brownies in a single layer on a baking sheet until firm, then transfer them to an airtight container or freezer bag. They’ll keep for up to 3 months. Thaw in the fridge or at room temperature before eating.
