01 - Preheat the 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 top 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 smooth and creamy. Drop spoonfuls of the cheesecake mixture evenly over the strawberry filling layer.
04 - Sprinkle the dry cake mix evenly over the entire surface. Do not stir or mix the layers together.
05 - Pour the melted butter evenly over the cake mix, ensuring as much surface area as possible is covered for a golden, crisp topping.
06 - Bake for 40 to 45 minutes until the top is golden brown and cooked through, and the cheesecake filling is bubbling around the edges.
07 - Allow the cake to cool for at least 20 minutes before serving. Serve warm or at room temperature.
