Preheat oven to 350 degrees

All ingredients need to be at room temperature

Make caramel by combining the sugar and water in a medium saucepan and cooking over moderate heat swirling saucepan occasionally until color begins to turn golden, about 12 to 15 minutes. Turn heat to low and continue cooking and swirling saucepan constantly until color is caramel brown. Remove from heat and using a towel or hot pad, pour into cakepan immediately tilt pan and swirl caramel to coat the bottom and sides well. It sets very quickly! Set aside.

In large bowl, beat cake mix, milk, oil and 3 eggs with electric mixer on medium speed about 1 minute then add sour cream and beat for another minute or two scraping bowl occasionally. Pour batter over caramel in pan.

In blender, place flan ingredients (4 Eggs, cream cheese, condensed & evaporated milk & vanilla) Cover; blend on high speed until smooth, about 40 seconds. Slowly pour mixture over batter. (Flan mixture will mix with batter, but they will separate during baking, forming 1 layer of cake and 1 layer of flan.)

Place cake pan in large roasting pan; add 1 inch of hot water to roasting pan

Bake about 1 hour 5 minutes to 1 hour 10 minutes or until toothpick inserted in center comes out clean. Remove cake pan from water bath to cooling rack. Cool about 30 minutes, if you let it cool too much the bottom caramel might stick to pan. After 30 minutes place serving plate upside down on cake pan and turn plate and pan over. Remove pan, cover Chocoflan and refrigerate overnight or at least 4 hours.

Enjoy!!
