Instructions

Step 1: Make the Peanut Butter Filling

In a large bowl, whisk together the pudding mix and cold milk until thickened. Add the peanut butter and mix until smooth. Fold in the whipped topping until fully combined and creamy.

Step 2: Layer It Up

In a 9x13-inch pan, arrange a single layer of graham crackers on the bottom (you may need to break some to fit). Spread half of the peanut butter filling on top. Repeat with another layer of graham crackers and the remaining filling. Top with a final layer of graham crackers.

Step 3: Make the Chocolate Ganache

In a microwave-safe bowl, heat the heavy cream until hot (not boiling). Add the chocolate chips and let sit for 2 minutes, then stir until smooth and glossy. Pour the ganache over the top layer of graham crackers and spread evenly.

Step 4: Chill and Serve

Cover and refrigerate for at least 6 hours — ideally overnight. This gives the graham crackers time to soften and become cake-like. When ready to serve, slice into squares and enjoy every creamy, chocolatey bite.

Tips & Variations
