Cake Mix Cheesecake Brownies

Heat oven to 350°F. Grease bottom only of 13x9-inch pan with shortening or cooking spray.

In medium bowl, stir cake mix, oil, water and 1 of the eggs until smooth. Stir in 1/2 cup of the chocolate chips. Spread batter into pan.

In medium bowl, beat cream cheese, sugar, vanilla and remaining 1 egg with electric mixer on low speed until smooth. Drop mixture by generous tablespoonfuls randomly onto batter; cut through batter with knife for marbled effect. Sprinkle with remaining 1/2 cup chocolate chips.

Bake 35 to 40 minutes or until toothpick inserted in brownie 1 inch from side of pan comes out almost clean. Cool completely in pan on cooling rack, about 1 hour 30 minutes. Cut into 4 rows by 4 rows.
