Prepare the strawberries by washing and slicing them, and set aside a few slices for decoration later.
In a mixing bowl, add the heavy whipping cream, powdered sugar, and vanilla extract, and using a hand mixer, whip until soft peaks form.
In a rectangular or square dish, lay down a layer of chocolate graham crackers, slightly overlapping them if necessary to cover the base.
Spread a generous layer of whipped cream over the graham crackers.
Layer a portion of your sliced strawberries on top of the whipped cream.
Continue layering the ingredients—graham crackers, whipped cream, and strawberries—until you reach the top of your dish, with the final layer being whipped cream.
Cover the dish with plastic wrap and allow it to chill in the fridge for at least 2 hours (or overnight for best results).
When ready to serve, remove from the refrigerator, slice, and top with any optional toppings you desire.
