Prep
- Preheat oven to 350°F. Line a 9x9-inch pan with foil, leaving an overhang, and grease lightly.
- Melt butter and chocolate together in a medium saucepan over low heat, stirring until smooth. Remove from heat and whisk in sugar until glossy. Beat in eggs one at a time, then stir in vanilla. Fold in flour and salt just until no streaks remain. Reserve 1/2 cup batter for swirling.
- Beat softened cream cheese with sugar until completely smooth. Add egg and dissolved espresso, beating until fluffy and well combined.
- Spread brownie batter in the prepared pan. Dollop cheesecake mixture over top, then add reserved brownie batter in spots. Drag a knife through the batters in figure-eight motions to create marbling - don't overmix or you'll lose the contrast.
- Bake 32-35 minutes until the center is set but still slightly soft and a toothpick comes out with moist crumbs. The cheesecake will look puffed and lightly golden at edges. Cool completely in pan on a wire rack, then refrigerate at least 1 hour before cutting clean squares.
Notes
For cleanest cuts, use a sharp knife wiped clean between slices. Espresso powder intensifies chocolate without making them taste like coffee - but use decaf if serving late. These keep refrigerated up to 5 days and actually improve in flavor after a day.
