Instructions
Preheat your oven to 350°F (175°C) and grease an 8x8-inch baking pan or line it with parchment paper, allowing for overhang for easy removal. Gather all ingredients for both brownie and cheesecake layers.
In a medium saucepan or microwave-safe bowl, melt the butter. Stir in 1 cup of granulated sugar and 1/3 cup of cocoa powder until the mixture is smooth. Add in the red food coloring, 1 teaspoon of vanilla extract, and 1 teaspoon of white vinegar. Mix well.
Incorporate the eggs one at a time, ensuring each is fully mixed in before adding the next. Once combined, fold in 1 cup of all-purpose flour until the batter is smooth and lump-free.
In a separate bowl, combine the softened cream cheese with 1/4 cup of sugar, and beat until creamy. Add 1 egg and 1 teaspoon of vanilla extract, mixing until smooth and lump-free. Ensure all ingredients are at room temperature for best results.
Pour most of the red velvet batter into the prepared baking pan, spreading it evenly. Gently pour the cheesecake layer over the brownie batter. Reserve 1/4 cup of the brownie batter for swirling on top.
Drop spoonfuls of the reserved batter onto the cheesecake layer, and use a knife or toothpick to create a marbled effect, being careful not to overmix.
Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Once baked, allow the brownies to cool in the pan for 10-15 minutes before transferring them to a wire rack to cool completely.
Once cooled, cut the brownies into squares and enjoy! Store any leftovers at room temperature for up to 2 days, in the refrigerator for up to a week, or freeze for up to 3 months.
For best results, make sure to measure your ingredients accurately and allow your cream cheese to come to room temperature before mixing. This will ensure a smooth cheesecake layer that blends perfectly with the red velvet brownie batter.
Additionally, be careful not to overbake the brownies, as they will continue to set as they cool. Enjoy your baking adventure!
