Ingredients:
- 1 stick (4 oz) Unsalted Butter, cubed
- 6 oz High-Quality Dark Chocolate (60–70%), roughly chopped
- 1 cup Granulated Sugar
- 1/4 cup Light Brown Sugar, packed
- 2 Large Eggs, room temperature
- 1 teaspoon Vanilla Extract
- 2/3 cup All-Purpose Flour
- 1/4 cup Dutch-Process Cocoa Powder, sifted
- 1/2 teaspoon Sea Salt
- 4 oz Full-Fat Cream Cheese, softened
- 1/2 cup Canned Pumpkin Purée (not pie filling)
- 1/4 cup Granulated Sugar (for swirl)
- 1 Large Egg Yolk
- 1 teaspoon Pumpkin Pie Spice Blend
Instructions:
- Preheat the oven to 175°C (350°F). Line an 8x8 inch baking pan with parchment paper, leaving an overhang on two sides.
- Melt the chopped dark chocolate and cubed butter together in a heatproof bowl set over simmering water (or microwave briefly). Stir until completely smooth and glossy. Remove from heat and allow to cool slightly (about 5 minutes).
- Whisk the granulated sugar and brown sugar into the cooled chocolate mixture until combined.
- Add the eggs one at a time, whisking vigorously for 30 seconds after each addition. Stir in the vanilla extract.
- Sift the flour, cocoa powder, and salt directly into the wet ingredients. Fold gently with a rubber spatula until just combined, ensuring no dry streaks remain.
- For the pumpkin swirl: In a separate bowl, beat the softened cream cheese and 1/4 cup sugar until perfectly smooth and lump-free. Stir in the pumpkin purée, the egg yolk, and the pumpkin pie spice until creamy.
- Pour approximately three-quarters (3/4) of the brownie batter into the prepared pan and spread it into an even layer.
- Drop the pumpkin mixture evenly over the brownie layer in large dollops, leaving gaps between them. Spoon the remaining chocolate batter into these gaps.
- Use a thin knife or skewer to gently drag through the batter, creating figure-eight patterns for a marble swirl. Be careful not to overmix or scrape the bottom of the pan.
- Bake for 35–40 minutes. The edges should look set, and the centre should still have a slight wobble. A toothpick inserted in the center should have moist, fudgy crumbs attached.
- Allow the brownies to cool completely in the pan on a wire rack (minimum 2 hours). Chill for 30 minutes before using the parchment paper sling to lift them out and cut them into 12 squares.
