Ingredients:
- 1 1/2 cups (150g) graham cracker crumbs
- 6 tablespoons (85g) unsalted butter, melted
- 1/4 cup (50g) granulated sugar
- Pinch of salt
- 1 cup (230g) creamy peanut butter (like Skippy or Jif)
- 1 cup (115g) powdered sugar
- 6 tablespoons (85g) unsalted butter, softened
- 1/4 teaspoon pure vanilla extract
- Pinch of salt
- 1 cup (170g) semi-sweet chocolate chips
- 1/2 cup (120ml) heavy cream
- 1 tablespoon (14g) unsalted butter
- Pinch of salt
Instructions:
- Combine graham cracker crumbs, melted butter, sugar, and salt in a bowl. Press firmly into the bottom of a 9x13 inch pan lined with parchment paper. Chill crust for 15 minutes.
- Cream together peanut butter, powdered sugar, softened butter, vanilla extract, and salt using an electric mixer until smooth and creamy.
- Spread the peanut butter filling evenly over the chilled graham cracker crust. Return to the refrigerator to chill for at least 1 hour.
- Heat the heavy cream until simmering. Pour the hot cream over the chocolate chips and butter in a bowl. Let sit for 1 minute, then whisk until smooth and glossy.
- Pour the chocolate ganache over the chilled peanut butter layer and spread evenly. Sprinkle with sea salt, if desired.
- Refrigerate for at least 2 hours (or longer for firmer bars) before cutting into squares. Use a warm knife for clean cuts.
