Cream Cheese Bars

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Grease and flour a 15×10-inch sheet pan.

Step 2
Make the cake mix layer: Stir cake mix, melted butter, and egg in a bowl until well combined. Press mixture into the prepared sheet pan.

Step 3
Make the cream cheese layer: Beat cream cheese and eggs in a bowl until combined. Gradually mix in confectioners' sugar. Pour mixture over the cake mix layer in the sheet pan.

Step 4
Bake in the preheated oven for 15 minutes. Reduce the oven temperature to 300 degrees F (150 degrees C), and continue to bake until a toothpick inserted at the center of the pan comes out with just a few moist crumbs clinging to it, 30 to 35 minutes more.

Step 5
Remove from the oven and let cool completely before cutting into 24 bars.
