Creating your Lemon Cream Cheese Dump Cake is straightforward! Just follow these easy steps:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C) for optimal baking conditions.

2. Prepare Baking Dish: Grease a 9×13 inch baking dish to prevent sticking and make for easy serving.

3. Mix the Cream Cheese Layer: In a medium bowl, combine the softened cream cheese, sour cream, and granulated sugar. Mix until smooth and creamy, ensuring no lumps remain.

4. Spread Cream Cheese Mixture: Spoon the cream cheese mixture into the prepared baking dish, spreading it evenly across the bottom.

5. Add Lemon Pie Filling: Next, pour the lemon pie filling over the cream cheese layer, smoothing it out gently with a spatula.

6. Combine Cake Mix and Butter: In a separate bowl, combine the lemon cake mix with the melted unsalted butter. Stir until the mixture is crumbly and mixed well.

7. Top with Cake Mixture: Sprinkle the cake mixture evenly over the lemon filling, ensuring it covers it completely.

8. Bake: Place the baking dish in your preheated oven and bake for 45-50 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.

9. Cool the Cake: Once baked, remove the dish from the oven and allow it to cool for at least 10 minutes.

10. Dust with Powdered Sugar: Before serving, dust the top of the cake with powdered sugar for an elegant finish.
