Ingredients You'll Need

¾ cup butter , melted
2 cups powdered sugar
2 cups graham crackers , crushed (about 16 whole crackers)
1¼ cups creamy peanut butter (for the base layer)
3 tablespoons creamy peanut butter (for binding)
2½ cups semi-sweet chocolate chips

Step-by-Step Instructions

Step 1: Prepare the Base

In a large mixing bowl, combine the melted butter , powdered sugar , crushed graham crackers , and 1¼ cups creamy peanut butter . Stir until the mixture is well combined and crumbly but holds together when pressed.

Pro Tip: If the mixture feels too dry, add an extra tablespoon of melted butter or peanut butter to help it stick.

Step 2: Press Into a Pan

Line an 8x8-inch square baking pan with parchment paper, leaving overhang on the sides for easy removal later. Press the graham cracker-peanut butter mixture evenly into the bottom of the prepared pan, using the back of a spoon or your hands to compact it firmly.
