Cheesecake Swirl Brownies

Ingredients

Equipment Needed

• •9-inch square baking pan
• •Parchment paper
• •Double boiler or heatproof bowl
• •Electric hand mixer or stand mixer
• •Offset spatula
• •Wire cooling rack

Instructions

1. 1

   Prepare the pan

   Position a rack in the center of your oven and heat to 325°F. Line a 9-inch square baking pan with parchment paper, leaving overhang on two sides for easy lifting. This lower temperature bakes both batters evenly without overbrowning the edges or curdling the cream cheese.

   Aluminum foil works if you're out of parchment. Butter it lightly to prevent sticking.
2. 2

   Melt chocolate and butter

   Combine the butter and both chocolates in a medium heatproof bowl set over a pot of barely simmering water. The water should not touch the bottom of the bowl. Stir occasionally until melted and smooth, about 5 minutes. The mixture will look glossy and pour like heavy cream. Remove from heat and let cool for 10 minutes. If you skip this cooling, your eggs will scramble on contact.

   A microwave works in 30-second bursts, stirring between each, but the double boiler gives you more control and a silkier result.
3. 3

   Build the brownie batter

   Whisk 1 cup sugar into the cooled chocolate mixture until combined. Add the 2 eggs one at a time, whisking after each until the batter turns glossy and slightly thickened. This is where structure develops. Stir in 1 teaspoon vanilla. Add the 3/4 cup flour and salt, folding with a spatula just until no dry streaks remain. The batter should be thick, dark, and fudgy. Set aside.

4. 4

   Make the cheesecake swirl

   In a separate bowl, beat the room-temperature cream cheese with an electric mixer until completely smooth, about 2 minutes. Scrape down the sides twice. Any lumps now become lumps in your finished brownies. Add the 1/4 cup sugar and beat until fluffy. Add the egg and 1/2 teaspoon vanilla, mixing until just combined. Fold in the tablespoon of flour by hand. The batter should be smooth, pourable, and the color of fresh cream.

5. 5

   Layer the batters

   Reserve 1/2 cup of the brownie batter. Spread the remaining brownie batter into your prepared pan, pushing it into the corners with an offset spatula. The layer should be even and about 1/2 inch thick. Drop the cheesecake batter in large spoonfuls across the surface, leaving some brownie visible between the dollops. Drop the reserved brownie batter in smaller spoonfuls over the cheesecake.

6. 6

   Create the swirl

   Using the tip of a butter knife or a wooden skewer, draw figure-eights through both batters. Work in long, confident strokes, dragging the knife through the entire depth of the pan. Five or six passes is plenty. You want visible contrast between the dark brownie and pale cheesecake, not a muddy blend. The pattern will shift slightly during baking, so don't aim for perfection.

   Wipe your knife between strokes if batter builds up on the blade. Clean lines create sharper contrast.
7. 7

   Bake until set

   Bake for 40 to 45 minutes. The brownies are done when the cheesecake swirls are set and no longer jiggle, and a toothpick inserted into the brownie portion comes out with moist crumbs, not wet batter. The center will still look slightly underdone. Trust it. Residual heat finishes the job. Overbaked cheesecake cracks, and overbaked brownies turn cakey.

8. 8

   Cool completely

   Let the brownies cool in the pan on a wire rack for at least 2 hours, preferably 3. Patience here is non-negotiable. Warm brownies crumble. Warm cream cheese smears. Once fully cooled, refrigerate for 30 minutes to firm up for clean cutting. Use the parchment overhang to lift the entire slab onto a cutting board.

9. 9

   Cut and serve

   Using a sharp chef's knife, cut into 16 squares, wiping the blade with a damp cloth between cuts for clean edges. Each piece should show the dramatic contrast of dark chocolate and cream cheese swirls. Serve at room temperature for the fudgiest texture, or slightly chilled if you prefer a denser bite.

Chef Tips

• •Room temperature cream cheese is essential. Cold cream cheese creates lumps that no amount of beating will smooth out. Leave it on the counter for at least an hour before starting.
• •The ratio of bittersweet to unsweetened chocolate creates depth. All bittersweet makes brownies too sweet. All unsweetened makes them bitter. This blend gives you adult chocolate flavor with enough sweetness to complement the tangy cream cheese.
• •For extra fudgy brownies, underbake by 3 minutes and increase the refrigeration time. The center will set as it chills.
• •These brownies slice cleanest when cold but taste best at room temperature. Cut them from the fridge, then let them warm on the counter for 15 minutes before serving.

Advance Preparation

• •Brownies can be made up to 3 days ahead and stored covered in the refrigerator. The flavors meld beautifully overnight.
• •Freeze uncut brownies wrapped tightly in plastic, then foil, for up to 2 months. Thaw overnight in the refrigerator before cutting.
• •Cut brownies can be frozen in a single layer, then transferred to a freezer bag. Thaw individual pieces at room temperature for 30 minutes.
• •The cheesecake batter can be made up to 24 hours ahead and refrigerated. Bring to room temperature and stir smooth before using.
