- ½ cup (120ml) heavy cream
- 1 tablespoon unsalted butter
Preparation Time

Step-by-Step Instructions
Step 1: Make the Cream Filling
- In a large mixing bowl, whisk the instant pudding mix and cold milk until thickened (about 2 minutes).
- Gently fold in the whipped topping until smooth and creamy. Set aside.
Step 2: Assemble the Layers
- In a 9×13-inch baking dish, arrange a single layer of graham crackers to cover the bottom.
- Spread half of the pudding mixture evenly over the crackers.
- Add another layer of graham crackers, then spread the remaining pudding mixture on top.
- Finish with a final layer of graham crackers as the “cake top.”
Step 3: Prepare the Ganache
- In a small saucepan, heat the heavy cream until just simmering (do not boil).
- Remove from heat and pour over the chocolate chips and butter in a bowl.
- Let sit for 1 minute, then whisk until smooth and glossy.
Step 4: Assemble and Chill
- Pour the ganache evenly over the top graham layer, spreading to the edges.
- Cover with plastic wrap and refrigerate for at least 6 hours, or overnight, until the crackers soften into a cake-like texture.
Step 5: Serve
- Slice into squares and serve chilled for the perfect creamy, layered bite.
Serving Suggestions
- Garnish each slice with fresh berries or shaved chocolate for extra flair.
- Drizzle with caramel sauce for a richer twist.
