Prepare the crust by mixing the graham cracker crumbs, sugar, and melted butter.
Press the crumb mixture evenly into the bottom of a 9x13 inch baking dish.
In a mixing bowl, beat the softened cream cheese, powdered sugar, and vanilla extract until smooth and creamy.
In a separate bowl, whip the heavy cream until soft peaks form, then gently fold it into the cream cheese mixture.
Spread half of the cheesecake mixture over the crust in an even layer.
Add a layer of sliced strawberries on top of the cheesecake mixture.
Spread the strawberry jam over the strawberries for added flavor.
Add the remaining cheesecake mixture and spread evenly.
Top with the remaining sliced strawberries and refrigerate for at least 4 hours before serving.
