Creating these Cheesecake Brownies is easier than you might think. Follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and line an 8×8-inch baking pan with parchment paper.

2. Make the Brownie Batter: In a medium saucepan, melt the unsalted butter over low heat. Remove from heat and stir in the granulated sugar until well combined. Mix in the eggs one at a time, followed by the vanilla extract.

3. Combine Dry Ingredients: In a separate bowl, whisk together the flour, cocoa powder, salt, and baking powder. Gradually add this dry mixture into the wet ingredients, stirring until just combined.

4. Prepare the Cheesecake Layer: In a mixing bowl, beat the softened cream cheese and granulated sugar until smooth and creamy. Add the egg and vanilla extract. Mix until well incorporated and set aside.

5. Layer the Mixtures: Pour half of the brownie batter into the prepared baking pan. Spread it evenly to cover the bottom. Then, add dollops of the cheesecake mixture over the brownie layer. Use a spoon to add the remaining brownie batter on top of the cheesecake.

6. Swirl the Layers: Using a knife or a toothpick, gently swirl the brownie and cheesecake layers together to create a marbled effect. Be careful not to overmix; you want to see distinct swirls.

7. Bake: Place the pan in the preheated oven and bake for 30-35 minutes. A toothpick inserted into the center should come out with a few moist crumbs attached. Allow the brownies to cool slightly before transferring them to a wire rack.
