Black Sesame Salted Caramel Brownie Bars
Fudgy chocolate, a nutty black sesame swirl, and a thin salted caramel finish.

The formula
Ingredients
Chocolate brownie
- ½ cup (113 g) unsalted butter
- 4 oz (115 g) dark chocolate, chopped
- ¾ cup (150 g) granulated sugar
- 2 large eggs, at room temperature
- 1 tsp vanilla extract
- ½ cup (65 g) all-purpose flour
- ¼ cup (20 g) unsweetened cocoa powder
- ¼ tsp fine salt
Sesame swirl and finish
- ¼ cup (60 g) unsweetened black sesame paste, stirred smooth
- 2 tbsp (25 g) granulated sugar
- 1 tbsp milk
- ¼ cup prepared caramel sauce
- 1 tsp toasted black sesame seeds
- ⅛ tsp flaky sea salt
Equipment
8-inch square metal pan, parchment, mixing bowls, saucepan
Allergens: Wheat, eggs, milk, sesame; check chocolate and caramel labels.
The process
Step by step
- Heat the oven to 350°F (175°C). Line the pan with parchment, leaving an overhang. Melt the butter and dark chocolate together over low heat, stirring. Remove from the heat and cool for 5 minutes.
- Whisk the ¾ cup sugar into the chocolate mixture, then add the eggs one at a time and the vanilla. Sift in the flour, cocoa, and fine salt. Fold just until no dry flour remains, then spread into the pan.
- Mix the black sesame paste with the separate 2 tbsp sugar and milk. Spoon nine small dollops over the batter. Draw a knife through the dollops in shallow loops; keep some dark swirls visible.
- Bake for 25–32 minutes, until the edges are set and a toothpick in the brownie portion comes out with moist crumbs, not liquid batter. Check that the center reaches 160°F (71°C). Cool in the pan on a rack for at least 1 hour before lifting and slicing into nine bars.
- Warm the prepared caramel just until pourable. Divide it over the bars, then sprinkle with the toasted sesame seeds and flaky salt. The finish is a thin drizzle, rather than a thick frosting.
The Devotti twist: Black sesame adds roasted depth to the chocolate; the caramel stays on top so the brownie texture remains distinct.
