Step 1: Make the Whipped Cream : In a large mixing bowl, combine cold heavy cream, powdered sugar, vanilla, and a pinch of salt. Beat using an electric mixer on medium-high speed until stiff peaks form (about 3–4 minutes). Taste and adjust sweetness if needed. (Optional: Fold in prepared pudding mix for a thicker, custard-like filling.)
Step 2: Prepare the Base Layer :In a 9x13-inch baking dish, spread a thin layer of whipped cream to help the graham crackers stick. Arrange a single layer of graham crackers over the cream, breaking pieces as needed to cover the entire base.
Step 3: Add the Cream Layer : Spread a generous layer of whipped cream over the graham crackers. Add a layer of sliced strawberries (if using). Repeat the layers — graham crackers, whipped cream, fruit — until you reach the top of the dish (usually 3–4 layers).
Step 4: Finish the Top Layer : End with a smooth layer of whipped cream on top. Garnish with chocolate shavings, fresh fruit, or crushed graham crackers.
Step 5: Chill and Set : Cover the dish with plastic wrap or foil. Refrigerate for at least 6 hours, preferably overnight, to allow the graham crackers to soften and the layers to meld.
