Preheat oven to 350. Grease a 9x13 baking pan and set aside.
Prepare the brownie layer:
In a medium bowl, whisk together oil, eggs, sugar, and Misceo until smooth. Add salt, baking powder and vanilla; whisk to combine.
Switch from a whisk to a rubber spatula and gradually mix in the flour. Stir gently until combined. Pour batter into prepared baking pan. Set aside.
Prepare the cheesecake layer:
Add all ingredients to the bowl of a blender. Blend until combined and smooth. Pour over brownie batter in pan.
Bake for 45-50 minutes, until the top is set but the center is still slightly jiggly. Set aside to cool completely (a few hours) before glazing and serving.
Prepare glaze:
Combine all ingredients in a small bowl. Whisk to combine. Pour glaze over cooked bars.
Cut into squares and serve.
Plan ahead: these bars can be prepared and frozen until ready to use. For best results, freeze whole and cut before serving.
