Instructions
Peanut Butter Layer
- Line an 8-inch or 9-inch square baking pan with parchment paper or aluminum foil, leaving some overhang for easy removal.
- Break the graham crackers into pieces and place them in a food processor. Pulse until fine crumbs form. Add the confectioners’ sugar and salt. Pulse a few times to combine.
- Pour in the melted butter and add 1 cup peanut butter. Process until the mixture is evenly combined and resembles thick cookie dough, scraping down the sides as needed.
- Transfer the mixture to the prepared pan and press firmly into an even layer.
Make the Chocolate Topping
- Combine the remaining 2 tablespoons peanut butter and chocolate chips in a microwave-safe bowl.
- Microwave in 20-second intervals, stirring between each, until smooth. Alternatively, melt together in a saucepan over low heat.
- Spread the chocolate mixture evenly over the peanut butter layer.
- Refrigerate until completely firm, at least 2 hours.
- Remove from the refrigerator and let sit at room temperature for about 10 minutes before cutting into bars.
- Serve chilled or at cool room temperature.
