01 - Preheat oven to 350°F. Grease a 9x13 inch baking dish with butter or nonstick spray.
02 - Spread the fresh or frozen sliced strawberries evenly across the bottom of the prepared baking dish. Spoon the strawberry pie filling over the strawberries and spread it into an even layer.
03 - In a mixing bowl, beat the softened cream cheese with granulated sugar and vanilla extract using an electric mixer or whisk until completely smooth and creamy.
04 - Drop spoonfuls of the cheesecake mixture evenly over the strawberry filling layer. Do not spread or stir — the dollops will spread naturally during baking.
05 - Sprinkle the dry cake mix evenly over the entire surface, ensuring full coverage. Do not stir or mix into the layers below.
06 - Pour the melted butter evenly over the dry cake mix, covering as much surface area as possible to help the cake mix bake into a golden, crumbly topping.
07 - Bake for 40 to 45 minutes until the top is golden brown and set, and the cheesecake filling is bubbling around the edges.
08 - Allow the cake to cool for at least 20 minutes before serving. Serve warm or at room temperature. Pairs beautifully with a scoop of vanilla ice cream or a dollop of whipped cream.
