Method
Prep and mix the red velvet batter
- Preheat oven to 350F and line a 9x13 pan with parchment so the brownies lift out cleanly.
- Whisk melted unsalted butter and granulated sugar until smooth, then beat in the eggs, vanilla, and red food coloring until evenly colored.
- Fold in all-purpose flour, cocoa powder, white vinegar, and salt just until no dry streaks remain.
- Spread the batter evenly in the lined pan.
Make the swirl and bake
- Beat cream cheese, sugar, egg, and vanilla until smooth, then dollop the mixture over the brownie batter.
- Swirl the cream cheese into the batter with a gentle motion to create marbled ribbons.
- Bake at 350F for 25–30 minutes until the center looks set and a toothpick comes out with moist crumbs.
Finish
- Cool completely before cutting so the brownies hold their shape and the swirl firms up.
Notes
Pro tip: for the deepest red interior, start with 2 tbsp red food coloring and increase to 3 tbsp if you want a stronger color. Store airtight at room temperature up to 3 days or refrigerate up to 5 days; freeze baked brownies up to 2 months. For a dairy-reduced option, use reduced-fat cream cheese and standard butter substitutes that bake well.
