Ingredients:
- 1 stick (1/2 cup / 115 g) Unsalted Butter, cubed
- 7 oz (200 g) High-Quality Dark Chocolate (70% cocoa minimum), roughly chopped
- 3/4 cup (150 g) Granulated Sugar (for brownie)
- 2 Large Eggs, room temperature
- 1 teaspoon (5 ml) Pure Vanilla Extract (for brownie)
- 3/4 cup (100 g) All-Purpose Flour
- 1/4 cup (25 g) Unsweetened Cocoa Powder
- 1/2 teaspoon (3 g) Fine Sea Salt
- 8 oz block (225 g) Full-Fat Cream Cheese, softened
- 1/4 cup (50 g) Granulated Sugar (for swirl)
- 1 Large Egg Yolk
- 1/2 cup (120 g) Pumpkin Purée (not pie filling)
- 1/2 teaspoon (2.5 ml) Pure Vanilla Extract (for swirl)
- 1/2 teaspoon (2.5 g) Ground Cinnamon
- 1/4 teaspoon (1.25 g) Ground Ginger
- 1/8 teaspoon (0.6 g) Ground Nutmeg
Instructions:
- Preheat the oven to 175°C (350°F). Line the 8x8 inch baking pan with parchment paper, leaving an overhang on two sides to act as a sling.
- Combine the chopped dark chocolate and cubed butter in a large, heatproof bowl. Melt slowly using a double boiler or microwave (in 30-second intervals) until smooth.
- Remove from heat. Whisk in the 3/4 cup of granulated sugar until combined. Add the 2 large eggs, one at a time, whisking vigorously for about 30 seconds after each addition. Stir in the vanilla extract.
- Gently fold in the all-purpose flour, cocoa powder, and salt using a rubber spatula until just combined. Stop mixing when you no longer see streaks of dry flour (Do not overmix).
- Pour approximately 3/4 of the brownie batter into the prepared pan and spread evenly. Reserve the remaining 1/4 cup of batter for swirling.
- In a separate medium bowl, beat the room-temperature cream cheese and 1/4 cup sugar using an electric mixer until completely smooth, fluffy, and lump-free (about 2 minutes).
- Add the egg yolk and the remaining vanilla extract to the cheesecake mixture. Beat briefly until just combined.
- Gently fold in the pumpkin purée, cinnamon, ginger, and nutmeg until the mixture is uniform and creamy orange.
- Evenly dollop the pumpkin cheesecake mixture over the brownie layer in the pan. Then, drop small spoonfuls of the reserved 1/4 cup of brownie batter randomly over the cheesecake layer.
- Using a thin skewer or knife, gently run it through the layers, making S-shapes or figure-eights to create a marbled effect (aim for 5-6 passes; avoid overswirling).
- Bake for 35 to 40 minutes. The edges should look set, and the center should still look slightly soft. A skewer inserted into the brownie portion should come out with moist, sticky crumbs.
- Remove the pan from the oven and let it cool completely on a wire rack for at least 2 hours. For the cleanest slices, chill the brownies in the refrigerator for another hour before slicing.
