Ingredients

Instructions

  1. Step 1: Line an 8x8-inch square pan with parchment paper. In a medium bowl, combine 2 cups graham cracker crumbs, 1 cup powdered sugar, 1/2 cup melted unsalted butter, and 1 cup creamy peanut butter. Mix thoroughly until a firm dough forms.
  2. Step 2: Press the peanut butter mixture evenly into the bottom of the prepared pan, smoothing the surface with a spatula.
  3. Step 3: In a small saucepan over low heat, warm 1 1/2 cups semi-sweet chocolate chips with 1/4 cup heavy cream, stirring constantly until the chocolate is melted and the mixture is smooth and glossy.
  4. Step 4: Pour the melted chocolate mixture over the peanut butter base and spread evenly with a spatula. Refrigerate for at least 2 hours until firm before slicing into bars.
