Ingredients

▢ 57 grams salted butter, plus more for the pan
▢ 4 ounces bittersweet chocolate, finely chopped
▢ 16 grams cocoa powder
▢ 3 large eggs
▢ 241 grams white sugar
▢ 1 tablespoon vanilla extract
▢ 0.5 teaspoon table salt
▢ 180 grams tahini
▢ 43 grams all-purpose flour

Instructions

Prep the Pan and Heat the Oven

Heat the oven to 350ºF with a rack in the middle position, so the brownies bake evenly without scorching on the bottom. Line an 8-inch-square baking pan with 2 pieces of foil, letting plenty hang over all sides like little handles for lifting later.
Lightly coat the foil with butter, paying extra attention to the corners where fudgy brownies love to cling. The goal is an easy release and clean edges when you slice.

Brown the Butter, Then Build the Chocolate Base

In a medium saucepan over medium heat, melt the butter and keep it going until it browns, the foam settles a bit, and you smell that toasted, hazelnut-like aroma. You are looking for golden-brown specks on the bottom, not black, so swirl the pan and watch closely.
Remove the pan from the heat, then add the finely chopped chocolate and cocoa powder. Whisk until the mixture is smooth and shiny, with no dry cocoa pockets, and the chocolate looks like satin.

Mix the Tahini Batter and Reserve the Swirl

In a large bowl, whisk the eggs, sugar, vanilla extract, and table salt until slightly thickened, about 1 minute. The mixture should look glossy and a little paler, with ribbons that briefly sit on the surface before melting back in.
Whisk in the tahini until the batter turns creamy and cohesive, like a loose sesame custard. Fold in the flour and the 1/2 teaspoon espresso powder just until you stop seeing streaks of dry flour, because overworking here steals the fudgy bite.
Set aside 1/2 cup of the mixture for the swirl, and keep it nearby so you do not forget it once the chocolate shows up.

Combine, Swirl, Top, and Bake

Pour the warm chocolate mixture into the remaining tahini mixture and fold until the color is even and deep, with no marbled streaks hiding in the bottom of the bowl. The batter should look thick, glossy, and spoonable.
Spread the batter evenly in the prepared pan, then dollop the reserved tahini mixture across the top like little clouds. Use the tip of a paring knife to draw slow, confident figure-eights, just enough to create a clear swirl without blending everything into one shade.
Generously sprinkle toasted black and white sesame seeds over the top, then finish with flaky sea salt so you get crunch and pop in every square.
Bake until the edges are set but the center remains moist, 28 to 32 minutes. The middle should still have a slight jiggle when you nudge the pan, and the top will look set and shiny rather than wet.
Cool in the pan on a wire rack for 30 minutes, then use the foil handles to lift the brownies out. Cool on the rack for at least another 30 minutes before peeling off the foil, then cut into 2-inch squares once fully cooled for the cleanest lines.

Notes

Preparation Tip: Stir the tahini thoroughly in the jar before measuring, as the solids sink and the oil floats. This ensures a consistent texture and flavor.

Swirl Technique: Keep the swirl motion minimal. A paring knife tip works better than a butter knife because it draws thin lines without dragging big waves of batter.

Slicing Tip: Chill the brownies in the fridge for 1 hour before slicing. Cold firms the fats and sets the crumb, giving you clean, pastry-case-style squares.
