I was intimidated with making a cheesecake and the springform pan idea, but it ended up being very easy and delicious.
1 small (10 ounce) package fudge brownie mix
3 (8 ounce) packages cream cheese, softened
1 (11 ounce) can sweetened condensed milk
2 teaspoons vanilla
1/2 cup mini chocolate chips
Preheat oven 350 degrees. Grease bottom of 9 inch spring form pan. Prepare brownie mix as package directs. Spread in pan and bake 35 minutes, or until set. Remove from oven and set aside. While brownie mix is baking, beat cream cheese in large mixing bowl until fluffy. Gradually add condensed milk, mixing well. Add eggs and vanilla, mixing until well blended. Stir in chips. Pour mixture over brownie shell. Reduce oven temperature to 300 degrees. Bake 50 to 60 minutes, until center is set. Allow to cool, then chill thoroughly in refrigerator. Serve and enjoy!
