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 350°F. Bake for 30 minutes, until cheesecake is set.
