Method

1. Make the chocolate mousse: Melt the dark chocolate, butter, and sea salt in a bowl over hot water, keeping the mixture cool. Mix in the egg yolks until smooth.
2. Whip the meringue: In a clean bowl, whisk the egg whites with a hand-held whisk until frothy and stiff. Gradually add the sugar to form a thick, glossy meringue.
3. Fold the mousse: Mix one-third of the meringue into the chocolate mixture to loosen. Gently fold in the remaining meringue in two additions. Chill the mousse in the fridge for at least 2 hours.
4. Make the caramel: Melt the butter in a saucepan over high heat and cook until browned. In a separate pan, simmer the cream and muscovado sugar, then gradually whisk in the browned butter until smooth. Remove from the heat, add the milk chocolate, and stir until smooth. Allow to cool fully.
5. Prepare the brioche rolls: Cut the brioche in half and butter each side well, then sprinkle with caster sugar. Heat a frying pan over medium and caramelise the cut sides for 1–2 minutes. Set aside.
6. Make the white chocolate straws: Place a baking tray lined with baking paper in the freezer. Melt half the white chocolate over hot water, then stir in the rest until cooled. Spoon into a piping bag and pipe long straws onto the cold tray. Freeze until needed.
7. Assemble and serve: Spread a thick layer of caramel onto the brioche base. Pipe or spoon chocolate mousse on top, then close the bun. Stack with white chocolate straws, dust with icing sugar, and chill the filled brioche for 30 minutes before serving. Napkins are recommended—these are delightfully messy!

What can you serve with this

1. Fresh raspberries: Their tartness cuts through the rich mousse and caramel.
2. Espresso or strong coffee: Balances the sweetness and enhances the chocolate notes.
3. Crème fraîche: A dollop adds cool, tangy contrast to each bite.
4. Roasted hazelnuts: For extra crunch and a nutty aroma (if not strictly nut-free).
