Ingredients
Method
- Prepare the pan. Line an 8x8 inch pan with parchment paper, leaving some hanging over two sides so you can lift the bars out later.
- Make the crust. Stir the graham cracker crumbs, sugar, and salt together. Add the melted butter and mix until the crumbs look like wet sand.
- Press the crust. Pack the crumbs firmly into the bottom of the pan with the back of a measuring cup or a flat glass. Chill for 15 minutes.
- Make the peanut butter layer. Beat the softened butter and peanut butter until smooth. Add the powdered sugar, vanilla, and salt, and mix until thick and creamy.
- Spread the filling. Press the peanut butter mixture evenly over the chilled crust. Smooth the top with a spatula, and chill for 20 minutes.
- Add the chocolate. Melt the chocolate chips and butter in 30-second bursts in the microwave, stirring each time, until smooth. Pour over the peanut butter layer and spread evenly to the edges.
- Chill. Refrigerate for at least 2 hours, until the chocolate is firm.
- Slice. Lift the block out with the parchment, let it sit for 5 to 10 minutes, and cut into 16 squares with a sharp knife.
Notes
• Peanut butter: Use regular creamy peanut butter such as Jif or Skippy. Natural peanut butter separates and makes the filling oily and soft.
• Graham crackers: Crush them finely in a food processor or in a zip bag with a rolling pin. Fine crumbs make a crust that holds together.
• Chocolate: Semi-sweet balances the sweet filling. Dark chocolate chips work for a less sweet top.
