1 (19.8 or 21.5-oz) box fudge brownie mix
3 (8-oz.) cream cheese, softened
1 can sweetened condensed milk
2 tsp. vanilla
1/2 cup mini chocolate chips
Preheat oven to 350. 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 mixing 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 chocolate chips at the last minute. Pour into prepared pan.
Reduce oven temperature to 300. Bake for 50 minutes or until center is set. Cool. Chill thoroughly.
Remove sides of springform pan (you may want to use a warm knife to separate the cheesecake from the sides of the pan). Garnish with you favorite whipped cream topping and then with a few leftover mini chips sprinkled over the top.
