Marbled cheesecake brownies

FOR THE BROWNIE BATTER:
¼ cups Butter
2 ounces, weight Chopped Dark Chocolate
½ cups Sugar
1 whole Egg
¼ cups All-purpose Flour
2 Tablespoons Unsweetened Cocoa Powder
½ teaspoons Pure Vanilla Extract

FOR THE CHEESECAKE BATTER:
4 ounces, weight Cream Cheese, Softened
3 Tablespoons Sugar
1 Tablespoon Egg Yolk
¼ teaspoons Pure Vanilla Extract

Preheat oven to 350ºF.
To make brownie batter, heat butter in the top pan of a double boiler. When butter is melted, whisk in chocolate until melted, then add in the sugar. Remove from heat and allow to cool for about 3 minutes before whisking in egg, flour, cocoa powder, and vanilla extract.
Spray a mini muffin pan generously with baking spray. Spoon brownie batter into each cup, filling each halfway. Set aside.
To make cheesecake batter, use a handheld mixer to combine all ingredients in a small bowl.

Spread the brownie batter into a pan, it's probably gonna be pretty thick.

Spoon the cheesecake mixture on top of the brownie batter and use a dull knife or even a spoon to swirl it around, giving it a good marbled effect.

Bake in the oven for 20-25 minutes or until; knife comes out clean. These wont really puff up alot they will be flat but very fudgy.
