Ingredients

Instructions

  1. Step 1: In a medium bowl, combine 1 1/2 cups graham cracker crumbs and 1/2 cup melted unsalted butter. Press mixture firmly into the bottom of an 8x8-inch square pan lined with parchment paper to form an even crust.
  2. Step 2: In another bowl, mix 1 cup creamy peanut butter and 1 cup powdered sugar until smooth and thick. Spread this peanut butter mixture evenly over the graham cracker crust.
  3. Step 3: In a small saucepan, heat 1/4 cup heavy cream over medium heat until it just starts to simmer, then remove from heat and stir in 1 cup semisweet chocolate chips until the chocolate is melted and mixture is smooth.
  4. Step 4: Pour the chocolate ganache evenly over the peanut butter layer and smooth the top with a spatula. Refrigerate for at least 2 hours until firm.
  5. Step 5: Once set, lift the dessert from the pan using the parchment paper and cut into 16 small squares to serve.
