Creating the Tangy Lemon Cream Cheese Dump Cake is a breeze if you follow these simple steps:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C). Prepare a 9×13-inch baking dish by greasing it lightly.
2. Mix Cake Batter: In a large bowl, combine the lemon cake mix, eggs, melted butter, and vanilla extract. Mix until well blended and smooth.
3. Prepare Cream Cheese Mixture: In another bowl, beat the softened cream cheese until creamy. Add sour cream, powdered sugar, lemon juice, and lemon zest. Mix until combined.
4. Layer Ingredients: Pour half of the cake batter into the prepared baking dish. Spread the cream cheese mixture evenly over this layer. Pour the remaining cake batter on top.
5. Bake: Place the dish in the preheated oven and bake for 40-45 minutes or until golden brown and a toothpick inserted comes out clean.
6. Cool: Remove from the oven and let the cake cool for about 20 minutes.
7. Serve: Slice and enjoy while warm or chilled according to personal preference.
