1. Preheat the oven to 350°F and line a 9×13-inch baking dish with parchment paper.

2. In a bowl, mix cake mix, melted butter, 2 eggs, and 1 tsp vanilla until combined.

3. Spread the cake mixture into the pan evenly using a spoon sprayed with non-stick spray.

4. In a separate bowl, beat cream cheese, remaining eggs, and vanilla until smooth.

5. Gradually add powdered sugar and continue to mix until creamy.

6. Pour cream cheese mixture over the cake base and spread evenly.

7. Bake for 35–40 minutes, until the edges are golden and the top is crinkled but slightly jiggly.

8. Cool completely before slicing into bars.
