Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C) and line an 8×8-inch (20×20 cm) baking pan with parchment paper. Lightly grease the parchment paper to prevent sticking.

Step 2: Prepare the Brownie Batter

In a large mixing bowl, whisk together melted butter and sugar until smooth and glossy. Add the eggs and vanilla extract, mixing until well combined.

Sift in the cocoa powder, all-purpose flour, salt, and baking powder. Gently fold the dry ingredients into the wet mixture using a spatula or whisk, being careful not to overmix. Overmixing can make the brownies dense instead of fudgy.

Pour about ¾ of the brownie batter into the prepared pan, spreading it evenly with a spatula. Reserve the remaining ¼ of the batter for the swirl effect.

Step 3: Make the Cheesecake Layer

In a separate bowl, beat the softened cream cheese and sugar together until smooth and creamy. Add the egg and vanilla extract, mixing until fully incorporated and lump-free.

Step 4: Swirl the Layers

Gently spread the cheesecake mixture over the brownie layer, making sure to cover the entire surface evenly. Then, dollop the remaining brownie batter on top in spoonfuls. Using a knife or skewer, swirl the two layers together to create a marbled effect. Don’t overdo it—you want distinct swirls rather than fully mixed layers.

Step 5: Bake to Perfection

Place the pan in the preheated oven and bake for 35-40 minutes, or until the edges are set but the center is slightly jiggly. A toothpick inserted into the center should come out with a few moist crumbs, but not wet batter.

Step 6: Cool and Slice

Allow the brownies to cool in the pan for about 30 minutes before transferring them to a wire rack to cool completely. For best results, refrigerate them for at least 1 hour before slicing—this makes them easier to cut and enhances the cheesecake texture.

Step 7: Serve and Enjoy!

Slice into squares and serve as is, or pair with a scoop of vanilla ice cream for an extra indulgence. Enjoy your homemade cheesecake brownies with a cup of coffee, tea, or a cold glass of milk!
