Step 1

Preheat the oven to the temperature specified on the brownie mix package instructions and line a 9x13-inch pan with foil.

Step 2

Prepare the brownie mix according to package instructions. Pour the mixture into the greased pan and spread it evenly. Set aside.

Step 3

In a bowl, combine cream cheese, egg, and sugar. Using an electric mixer, beat the ingredients on medium speed until the mixture is smooth.

Step 4

Pour the cream cheese mixture into the brownie batter. Swirl the mixtures together with a toothpick, skewer, or knife.

Step 5

Bake the mixture according to brownies' package instructions. To check for doneness, insert a toothpick into the center of the brownies. If it comes out with a few crumbs sticking to it, it's done baking.

Step 6

Let the brownies cool in the pan completely.

Step 7

Slice the cheesecake brownies into squares and serve. Enjoy!
