# Components:
→ Dry Ingredients
01 - 3/4 cup all-purpose flour
02 - 1/2 cup unsweetened cocoa powder
03 - 1/2 teaspoon fine sea salt
04 - 1/2 teaspoon baking powder
→ Wet Ingredients
05 - 1/2 cup unsalted butter, melted
06 - 4 ounces dark chocolate (60–70%), chopped
07 - 1 cup granulated sugar
08 - 1/3 cup light brown sugar, packed
09 - 3 large eggs, room temperature
10 - 1 teaspoon pure vanilla extract
→ Tahini Swirl
11 - 1/2 cup tahini, well stirred
12 - 2 tablespoons powdered sugar
13 - 1/4 teaspoon fine sea salt
→ Optional Topping
14 - 1/2 cup dark chocolate chips or chunks
15 - Flaky sea salt, for finishing (optional)
# Directions:
01 - Preheat oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving an overhang for easy removal.
02 - Whisk together the flour, cocoa powder, fine sea salt and baking powder in a medium bowl; set aside.
03 - Combine the chopped dark chocolate and melted butter in a heatproof bowl. Microwave in 20-second bursts, stirring between intervals, until smooth; allow to cool slightly.
04 - Whisk the granulated and brown sugars into the chocolate mixture. Add the eggs one at a time, whisking thoroughly after each addition, then stir in the vanilla.
05 - Gently fold the dry mixture into the chocolate mixture until just combined, taking care not to overmix to preserve fudgy texture.
06 - Pour the batter into the prepared pan and spread it evenly with a spatula.
07 - Whisk the tahini with the powdered sugar and 1/4 teaspoon salt until smooth and slightly pourable.
08 - Drop spoonfuls of the tahini mixture over the brownie batter. Use a knife or skewer to swirl the tahini gently into the batter to create a marbled pattern.
09 - Scatter the chocolate chips or chunks evenly over the surface, if using.
10 - Bake 28–32 minutes, or until the center is just set and a toothpick inserted into the center comes out with a few moist crumbs.
11 - Allow to cool completely in the pan on a wire rack, then lift out using the parchment overhang and cut into 12 squares. Sprinkle with flaky sea salt if desired before serving.
