Cheesecake Brownies

1 package brownie mix (Betty Crocker mix is the best I think for these brownies)
1 package (8 oz) cream cheese, softened
1/3 cup sugar
1 egg
1/2 tsp vanilla

Prepare brownie mix as directed on package. Pour the brownie mix into a greased 9x13-inch baking pan.

Beat the cream cheese with an electric mixer on medium speed until smooth. Add sugar and mix until blended. Add the egg and the vanilla; mix until just blended.

Pour the cream cheese mixture over the brownie mixture. Cut through the batter with a knife several times to create a marble effect.

Bake at 350 degrees for 35 to 40 minutes or until the cream cheese mixture is lightly browned. Cool and cut into squares. (DO NOT use brownie mixes that include the syrup pouch.)
