Directions

1. Preheat the oven to 350 degrees F. Spray an 8"x8" baking pan with cooking spray and place a parchment paper sling inside then set aside.
   
2. Add butter in a large bowl and melt in the microwave. Add 1 cup sugar, 1 teaspoon vanilla, cocoa powder, pinch of salt, food coloring, and vinegar, in that order, mixing between additions.
   
3. In a small bowl beat 2 eggs then stir it into the cocoa mix. Fold in the flour until lightly combined. Pour the batter into the prepared baking pan, saving 1/4 cup of the batter for the top.
   
4. In the bowl of an electric mixer with paddle attachment add cream cheese and beat for 2 minutes. Add 1/4 cup sugar, 1 egg, and 1 teaspoon vanilla into the bowl and mix for 2 more minutes.
   
5. Scrape the sides then mix one final time by hand. Gently spread the cream cheese layer on top of the brownie batter in the pan. Dollop the remaining brownie batter over the cream cheese layer.
   
6. Using a skewer, drag the tip through the cream cheese mixture to create a swirl pattern. Bake the brownies for 30 minutes then cover with foil and bake for 12 more minutes. Test the brownies with a toothpick until there are moist crumbs. Remove to a cooling rack and allow them to cool completely before cutting.
