1 (19.8 or 21.5 ounce) box fudge brownie mix
24 ounces cream cheese
1 can sweetened condensed milk
2 teaspoons vanilla extract
1/2 cup mini chocolate chips
Preheat oven to 350 degrees F. Grease the bottom only of a 9-inch springform pan.
Prepare brownie mix as per package instructions for chewy brownies. Spread evenly in the prepared pan. Bake for 35 minutes or until set.
Meanwhile, in a large mixer bowl, beat the cream cheese until fluffy. Gradually beat in the sweetened condensed milk. Add eggs and the vanilla; mix well. Stir in the mini chips at the last minute. Pour into prepared pan. Reduce oven temperature to 300 degrees F. Bake for 50 minutes or until center is set. Cool. Chill thoroughly.
Remove side of springform pan (you may want to use a warm knife to separate the cheesecake from the sides of the pan). Garnish with your favorite whipped cream topping and then with a few leftover mini chips sprinkled over the top.
