Step 1

Preheat the oven to 350 F. Line a 9x13-inch baking pan with parchment paper, or spray it with nonstick cooking spray. Set aside.

Step 2

In a small bowl, whisk together the flour, baking powder, and salt. In a large bowl, combine the sugar, ½ cup melted butter, 1 teaspoon vanilla extract, and 2 eggs until well-mixed. Slowly add in the flour mixture until fully incorporated. Press the dough flat into the bottom of the prepared pan.

Step 3

In a large bowl, add the cream cheese, remaining 2 eggs, 1 teaspoon vanilla extract, and ½ cup melted butter. Beat together until the mixture is creamy. Add in the powdered sugar 1 cup at a time until the cream cheese mixture is smooth. Pour it over the dough in the prepared pan, spreading it evenly to the edges.

Step 4

Bake in the preheated oven for 35 to 40 minutes, until the top is golden brown and the edges are set.

Step 5

Cool completely, then cut the bars and serve.
