1. Prepare the Base:

1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch (23x33cm) baking dish or line it with parchment paper for easy removal.
2. In a large bowl, mix the red velvet cake mix, 1 egg, and melted butter until well combined.
3. Press the dough evenly into the bottom of the prepared baking dish.

2. Make the Cream Cheese Topping:

1. In another bowl, beat the cream cheese with an electric mixer until smooth.
2. Add the eggs, vanilla extract, and melted butter. Mix until fully combined.
3. Gradually add the powdered sugar, beating on low speed until smooth and creamy.

3. Assemble the Cake:

1. Pour the cream cheese mixture over the red velvet base and spread it evenly with a spatula.

4. Bake:

1. Bake in the preheated oven for 40–45 minutes, or until the edges are set and lightly golden but the center is still slightly gooey.
2. Remove from the oven and let cool completely in the pan.

5. Serve:

1. Dust the cake with powdered sugar before serving for a decorative touch. Slice into squares or rectangles and enjoy!
