Step 1: Preheat Oven
Preheat your oven to 350°F (175°C).

Step 2: Prepare Your Baking Dish
Lightly grease a 12-inch oven-safe skillet, or a 9×9-inch or 9×13-inch baking dish with cooking spray or butter.

Step 3: Add Lemon Pie Filling
Evenly spread the lemon pie filling in the bottom of your prepared pan, creating a smooth, even layer.

Step 4: Sprinkle in White Chocolate Chips
Evenly sprinkle 1 cup of white chocolate chips over the top of the lemon pie filling.

Step 5: Add Cubed Cream Cheese
Distribute the cubed cream cheese pieces across the surface. Try to spread them out so every scoop gets a creamy surprise.

Step 6: Add Cake Mix Layer
Sprinkle the lemon cake mix evenly over the top. Use your hands or a spoon to make sure it covers the entire surface, reaching all the way to the edges.

Step 7: Top with Butter
Slice the unsalted butter into about 16 thin pads and evenly space them on top of the cake mix. These butter slices will melt and help form the golden crust during baking.

Step 8: Bake
Bake in the preheated oven for 1 hour, or until the top is golden brown and the filling is bubbling around the edges.

Step 9: Cool Slightly and Serve
Let the dump cake cool for about 10 minutes before serving. Optional: top with whipped cream or vanilla ice cream for a perfect finishing touch.
