Preheat oven to 350°F. Lightly spray (1) 9x13-inch baking dish with nonstick cooking spray.
Pour the cherry pie filling into the prepared pan and spread evenly to coat the bottom of the pan.
1 can cherry pie filling
In a large bowl with an electric mixer, beat the cream cheese and sugar on medium speed until smooth. Add in egg and vanilla and mix until combined. Pour the cream cheese mixture over the cherry pie filling and use an offset spatula, or spoon to spread evenly.
8 ounces cream cheese, ⅓ cup granulated sugar, 1 large egg, 1 teaspoon pure vanilla extract
In another large bowl, combine the dry cake (do not prepare cake according to package directions, you are just using the dry mix) with the melted butter until the butter is thoroughly incorporated; mixture will be crumbly. Sprinkle cake mix mixture over the cream cheese layer.
Bake in the preheated oven for 40-45 minutes or until golden brown. Allow the cake to cool for at least 15 minutes before serving with vanilla ice cream or whipped cream.
