Ingredients
Method
- Whisk melted butter and 1 cup sugar until shiny, then beat in 2 eggs and vanilla. Fold in flour, cocoa, and salt. Set aside 1/2 cup batter; spread the rest in a parchment-lined 8x8-inch pan.
- Beat cream cheese and 1/4 cup sugar until smooth, then mix in egg, vanilla, and sour cream.
- Pour cheesecake filling over brownie layer; drop reserved brownie batter in 8 to 10 dollops. Swirl with a knife in both directions to create ribbons.
- Bake at 350°F (175°C) for 30 to 35 minutes, until edges are set and center jiggles as one mass.
- Cool in pan 1 hour, then chill in fridge at least 2 hours. Lift out by parchment and slice into 16 bars.
Notes
Cool completely before slicing for clean edges. Chilling the bars for 2 hours after baking helps the layers set firmly, but you can skip the chill if you are in a hurry. The slices will just be a little softer.
