1 pkg. chocolate cake mix (I used Devil's cake mix)
1 (8 oz.) pkg. cream cheese, softened
2 tbsp. butter, softened
1 tbsp. cornstarch
1 (14 oz.) can Eagle Brand sweetened condensed milk (NOT evaporated milk)
1 egg
1 tsp. vanilla

Preheat oven to 350 degrees. Prepare cake mix as package directs. Pour batter into well greased and floured 10" bundt pan. In small mixer bowl, beat cream cheese, butter and cornstarch until fluffy. Gradually beat in sweetened condensed milk then egg and vanilla until smooth. Pour evenly over cake batter. Bake for 50 to 55 minutes or until toothpick inserted near center comes out clean. Cool 10 minutes. Remove from pan. Cool thoroughly.

Glaze or garnish with your favorite frosting. (I used half a can of Hershey's Chocolate Fudge Topping, it was great on the cake! This is easy to make and looks like you spent half the day in the kitchen.)
