Mix batter ingredients together in a pre-sprayed 8 X 8-inch baking dish.  Allow mixture to rest while preparing blueberry sauce and cheesecake.   Combine blueberry sauce ingredients in a saucepan and bring to a boil.   Boil for 1 to 2 minutes until sauce is thickened.  Whip cheesecake ingredients in a mixing bowl with an electric mixer until smooth.

Top batter with dollops of cheesecake mixture and blueberry sauce.  Swirl mixtures together using a knife.

Bake by placing in a COLD oven; set temperature to 350ºF. Bake for 30 minutes, until cheesecake is set.
