Step1. Stiff Creamy Filling1. In a large mixing bowl, whisk together two cans of vanilla pudding mix and 3 cups of milk. Thereafter, whisk until such a time that the mix thickens, which usually should take about 2 minutes to 3 minutes.2. Fold in an 8-ounce container of whipped topping (or homemade whipped cream). Mix slowly until the filling is smooth and fluffy.
Step2. Assembling the Layers1. Spread a thin layer of pudding mixture over the bottom of a 9x13-inch baking dish to prevent sticking.2. Arrange a layer of graham crackers over the pudding. Break crackers as needed to cover the entire base without overlapping.3. Spread a generous layer of pudding mixture over graham crackers. This coat must be even.4. Keep repeating the layers: graham crackers, pudding, graham crackers, and pudding. It will end with pudding mixture.
Step3 Preparing the Chocolate Ganache1. Place 1 cup chocolate chips in a heat-proof bowl.2. Heat 1/2 cup heavy cream in a saucepan until it begins to boil. Pour the cream over the chocolate chips and let it sit for a minute.3. Stir smooth and glossy.4. Allow the ganache to cool slightly before pouring it evenly over the top layer of pudding. Spread with a spatula for that polished finish.
