Next, use an electric blender at medium to high speed to blend the cream cheese until light & creamy. Then blend in the ⅔ cup of sugar, 2 eggs, & 2 teaspoons vanilla extract. Set to the side.
Puree the blueberries & sugar, strain if desired.
In a baking dish (13X9) sprayed with oil or lined with parchment paper, pour the brownie mix & spread evenly on the bottom of the pan. Then cover with the cheesecake mixture. Finally, drizzle & swirl the blueberry mixture on top of the cheesecake.
