Step-by-Step Instructions
- Preheat your oven to 175°C (350°F) and line a 20 cm square baking pan with parchment paper.
- In a heatproof bowl, melt the unsalted butter and chopped dark chocolate over simmering water, stirring until smooth, then let cool slightly.
- Add granulated sugar to the melted chocolate mixture, then beat in the eggs one at a time, mixing thoroughly after each addition, and blend in vanilla extract.
- In a separate bowl, sift together the flour, cocoa powder, and salt, then gently fold this dry mixture into the chocolate mixture until just combined.
- Fold in the crushed graham crackers, pour the batter into the prepared pan, and smooth the top.
- Bake for 20–25 minutes until the edges are set and the center is fudgy, then let cool completely in the pan.
- Bloom the powdered gelatin by sprinkling it over cold water in a small bowl and letting it sit undisturbed for about 5 minutes.
- In a saucepan, combine sugar, corn syrup, and water, heating over medium until dissolved and reaching 115°C (soft-ball stage).
- While the syrup is heating, whip the egg whites until soft peaks form, then slowly pour in the hot syrup while continuing to whip until stiff peaks form.
- Gently fold in the vanilla bean seeds and spread the marshmallow topping over the cooled brownie base.
- Toast the marshmallow topping with a kitchen torch or under the broiler until golden brown.
- Let cool for about 10 minutes before slicing into squares.
