If using a homemade graham cracker crust, prepare it ahead and refrigerate while making the rest of the pie. Here’s a recipe for homemade graham cracker crust that you can follow if you wish - https://www.manilaspoon.com/2015/09/yummy-blueberry-cheesecake.html
In an electric mixer, beat the softened cream cheese, heavy cream, and sugar until smooth, roughly 3-4 minutes. Add the vanilla extract and 3 tablespoons of strawberry or raspberry jam. Mix just until blended. Stir the cooled chocolate mixture into the cream mixture until smooth. Pour the mixture into the prepared crust. Refrigerate until fully set. This can be made 2 days ahead and maybe frozen at this point. Thaw the cheesecake thoroughly before you add the sliced strawberries.
