Make Brownie Batter: In a bowl, whisk together cocoa powder, flour, baking powder, and salt. In another bowl, combine sugar substitute, applesauce, vanilla, and eggs. Gradually add dry ingredients to wet ingredients, mixing until smooth.
Create Cheesecake Layer: In a separate bowl, beat together cream cheese, sugar substitute, vanilla, and eggs until creamy.
Layer in Dish: Grease a baking dish and spread half the brownie batter on the bottom. Add cheesecake layer, then drop spoonfuls of remaining brownie batter on top.
Swirl: Use a knife to gently swirl the layers for a marbled effect.
Bake: Bake until a toothpick inserted comes out with moist crumbs but not wet.
Cool and Serve: Let cool before cutting into squares. Enjoy these delicious and low-calorie brownies!
