Crust:

1. In a bowl, combine graham cracker crumbs, melted unsalted butter, and granulated sugar. Press the mixture into the bottom of a 9×13-inch baking dish to form the crust.

Filling:

1. In a mixing bowl, beat the softened cream cheese until smooth.
2. Add granulated sugar and vanilla extract, continuing to beat until well combined.
3. Gently fold in the whipped heavy cream until the filling is smooth and airy.

Cherry Topping:

1. In a saucepan, combine pitted and halved cherries, granulated sugar, cornstarch, water, and lemon juice.
2. Cook the cherry mixture over medium heat, stirring constantly until it thickens. This usually takes about 5-7 minutes.
3. Remove the saucepan from heat and let the cherry topping cool slightly.
4. Spoon the cherry topping over the cream cheese filling in the baking dish, spreading it evenly.
