1 package (19.6 ounces) brownie mix
1 package Philadelphia brand cream cheese, softened
1/3 cup sugar
1 egg
1/2 teaspoon vanilla

Preheat oven to 350. Grease a 13 x 9 inch baking pan. Prepare brownie mix as directed on package. Pour into prepared pan. Beat cream cheese with electric mixer on medium speed until smooth. Add sugar, mixing until well blended. Add egg and vanilla; mix just until blended. Pour cream cheese mixture over brownie mixture; cut through batter with knife several times for marbled effect. Bake at 350 for 35-40 minutes or until cream cheese mixture is lightly browned. Cut into 24 squares.
