Pour out 2/3 of the batter into the pan & set the rest aside.
For the cheesecake - mix all ingredients together needed to create this and mix together until smooth. Set aside until brownie layer is done. **PRO-TIP** Use "whipped cream cheese" over regular.
Layer the cheesecake base over the brownie layer, then drizzle remaining 1/3 of brownie mixture over the top to create a marble effect using a butter knife.
Bake for 30-35 minutes until edges are a nice golden brown & center is thoroughly cooked.
