1/2 cup butter
2-oz dark chocolate, coarsely chopped
1 cup sugar
2 large eggs
1 tsp vanilla extract
1 1/2 tsp red food coloring
2/3 cup all purpose flour
1/4 tsp salt
8-oz cream cheese, room temperature
1/3 cup sugar
1 large egg
1/2 tsp vanilla extract
Preheat oven to 350F. Butter the bottom and sides of a 8 inch metal baking pan. Put a long piece of parchment paper in the bottom of the pan, letting the parchment extend up two sides of the pan and overhang slightly on both ends. (This will make it easy to remove the bars from the pan after they have baked.) Butter the parchment.*
In a a double boiler, or a small, heatproof bowl over a pot of simmering water, melt butter and chocolate together. Stir until combined and very smooth. Set aside to cool for a few minutes.
In a large bowl, whisk together sugar, eggs, vanilla extract, and red food coloring. Add chocolate mixture and stir until smooth. Add flour and salt and stir until dry ingredients are just combined into the mixture.
Pour into prepared pan and spread into an even layer.
To prepare cheesecake mixture, beat cream cheese, sugar, egg and vanilla extract in a medium bowl until smooth. Distribute the cheesecake mixture in 8 dollops over batter in the pan. Swirl in with a knife or spatula.
Bake for 35-40 minutes, until brownies and cheesecake are set. A knife inserted into the cheesecake mixture should come out clean and the edges will be lightly browned.
Let cool completely in pan on a cooling rack before lifting out the parchment paper to remove the brownies.
*I don’t own an 8-in metal baking pan. I used an 8-in glass Corningware dish and no parchment paper. I baked my brownies for 35 minutes exactly and they were done.
