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 — the dollops will naturally settle during baking.
05 - Sprinkle the dry cake mix evenly over the entire surface, covering the cheesecake layer completely. Do not stir or mix.
06 - Pour the melted butter evenly over the dry cake mix, ensuring as much of the surface area as possible is coated. This helps the cake mix develop a golden, crisp topping.
07 - Bake for 40 to 45 minutes until the top is golden brown and the cheesecake mixture is bubbling around the edges. The center should be set and no longer jiggly.
08 - Allow the cake to cool for at least 20 minutes before serving. Enjoy warm or at room temperature, optionally topped with vanilla ice cream or whipped cream.
