Follow these easy steps to create the amazing Lemon Cream Cheese Dump Cake:

1. Preheat your oven to 350°F (175°C). Prepare a 9×13-inch baking dish by greasing it lightly.
2. Mix Cream Cheese: In a medium mixing bowl, beat the softened cream cheese until smooth. Add powdered sugar and vanilla extract, mixing until well combined and creamy.
3. Prepare Cake Layer: In another large bowl, combine the lemon cake mix, melted butter, and eggs. Stir well until all ingredients are mixed together.
4. Add Soda: Slowly pour in the lemon-lime soda, stirring gently until combined. Be careful not to overmix.
5. Layer Ingredients: Pour the cake batter into the prepared baking dish and smooth it to even out. Then, dollop the cream cheese mixture on top, spreading it gently.
6. Add Lemon Zest: If using lemon zest, sprinkle it over the cream cheese layer for added flavor and a pop of color.
7. Bake: Place the baking dish in the preheated oven and bake for 40-45 minutes. The top should be golden brown, and a toothpick inserted in the center should come out clean.
8. Cool: Once baked, remove the dish from the oven and let the cake cool for about 10-15 minutes before serving.
