👩‍🍳 INSTRUCTIONS

Step 1: Make the Cream Filling

  1. In a large mixing bowl, whisk together:
    • Instant vanilla pudding mix
    • Cold milk
  2. Whisk for about 2 minutes until thick and smooth.
  3. Gently fold in the whipped topping until fully combined.
  4. Set aside.

Step 2: Assemble the Cake

  1. Use a 9×13-inch baking dish.
  2. Arrange a single layer of graham crackers on the bottom, breaking pieces as needed to fit.
  3. Spread ½ of the pudding mixture evenly over the crackers.
  4. Add another layer of graham crackers.
  5. Spread the remaining pudding mixture on top.
  6. Finish with a final layer of graham crackers.

Step 3: Prepare the Chocolate Topping

Ganache Method

  1. Heat the heavy cream in a saucepan until just beginning to simmer (do NOT boil).
  2. Remove from heat and add chocolate chips and butter.
  3. Let sit for 2–3 minutes.
  4. Stir until smooth and glossy.
  5. Stir in vanilla extract.
  6. Let cool slightly (5–10 minutes) before spreading.

Frosting Method

  1. Microwave frosting for 15–20 seconds.
  2. Stir in milk until pourable but thick.
  3. Spread evenly over the top layer of graham crackers.

Step 4: Chill

  1. Cover the dish with plastic wrap or foil.
  2. Refrigerate for at least 4 hours, preferably overnight.
    • This allows the graham crackers to soften into a cake-like texture.

🍰 SERVING

  • Slice with a sharp knife.
  • Serve cold.
  • Optional garnish: shaved chocolate, cocoa powder, or mini chocolate chips.

⭐ TIPS FOR BEST RESULTS

  • Use whole milk for the creamiest texture.
