2cups(340g)semisweet chocolate, chopped (or good quality chocolate chips - see note)
1 ½cups(318g)granulated sugar
1cup(212g)lightly packed brown sugar
6large(300g)eggs
2tablespoonsred liquid food coloring
1tablespoonvanilla extract
1 ¾cups(249g)all-purpose flour
¼cup(21g)natural, unsweetened cocoa powder

Cheesecake Batter:
16ounces(454g)cream cheese, softened
1cup(212g)granulated sugar
¼cup(36g)all-purpose flour
2large(100g)eggs
1teaspoonvanilla extract
Instructions
Preheat the oven to 325 degrees F. Lin a 9X13-inch baking pan with parchment paper or foil (I suggest using a metal baking pan for even baking) and lightly grease with cooking spray.
In a microwave-safe bowl, combine the butter and chocolate and cook for 1-minute intervals at 50-60% power, stirring in between, and continuing to cook until melted (don't over heat).
Add the granulated sugar and brown sugar and whisk to combine. Add the eggs and whisk until fully combined.
Add the vanilla and food coloring and whisk until well combined.
Add the flour, cocoa (if the cocoa is really lumpy, sift it into the batter), and salt, and stir until just combined and no dry streaks remain.
Scoop out 1 cup batter and reserve for later. Spread the remaining batter evenly in the prepared pan.
For the cheesecake batter, in a medium bowl, cream together the cream cheese and granulated sugar until well combined. Add the flour and mix until well combined.
Add the eggs and vanilla and mix well, scraping down the sides of the bowl as needed.
Spread the cheesecake batter evenly over the brownie batter.
Dollop the reserved brownie batter by tablespoonfuls over the cream cheese layer. Using a wooden skewer or other thin tool (I use a clean knitting needle!), swirl the layers back and forth. Swirl quickly or the brownie batter will stiffen and it will be harder to swirl.
Bake the brownies until the edges are set and the top is shiny, about 45 minutes. Add additional time, if needed, as each oven and pan type may vary. The center of the brownies should be slightly jiggly; that's ok. An instant read thermometer inserted into the center should register 165 degrees F.
Let the brownie cool completely in the pan. Refrigerate for 2-4 hours (or overnight) until well chilled. Serve chilled or at room temperature.
Notes
Chocolate: my favorite chocolate chips for melting in brownie recipes are Guittard or Ghirardelli. Food Coloring: I haven't made this recipe with gel food coloring, so I don't know what the equivalent would be for the red food coloring called for in the recipe.
