1️⃣ Make the Pudding Filling
In a large bowl, whisk pudding mix + milk for 2 minutes until thick.
Gently fold in whipped topping until smooth.
2️⃣ Layer the Graham Crackers & Filling
In a 9x13-inch dish, spread a thin layer of pudding (to prevent sliding).
Add a single layer of graham crackers (break to fit as needed).
Spread ⅓ of the pudding mixture evenly over crackers.
Repeat layers 2 more times, ending with graham crackers on top.
3️⃣ Make the Chocolate Ganache
Heat heavy cream until steaming (microwave or stove).
Pour over chocolate chips + butter, let sit 1 minute, then stir until smooth.
Optional: Add vanilla or espresso for extra flavor.
4️⃣ Chill & Set
Pour ganache over the final cracker layer, spreading evenly.
Refrigerate at least 4 hours (or overnight for best texture).

Variations to Try
