Fondant au chocolat (French molten chocolate cake)

The iconic French molten chocolate cake: a crisp dark exterior giving way to a warm, flowing river of pure chocolate within

Origin: France

From the journey of Cocoa.

The fondant au chocolat, sometimes called mi-cuit (half-cooked) or moelleux au chocolat, became one of the defining restaurant desserts of late 20th-century French haute cuisine. Its invention is disputed: French chef Michel Bras developed his version of the dish in 1981 in Laguiole, using a frozen ganache centre inserted into the batter before baking (a technique that guaranteed the flowing centre regardless of timing. American chef Jean-Georges Vongerichten developed a separate version around 1987 that relied instead on precise underbaking. Both claimed the innovation; the dish went on to conquer every tasting menu and restaurant in the world. But the cultural roots are deeper: French pâtisserie had spent three centuries refining chocolate since it arrived from Spain in the 1600s, developing an entire vocabulary of technique) ganache, praline, tempering, couverture, that made such elegant precision possible. The fondant is the apex of that tradition: few ingredients, maximum skill, maximum drama.

Ingredients

batter

  • 150 g dark chocolate (70% cocoa solids), finely chopped
  • 150 g unsalted butter, plus extra for greasing
  • 3 large eggs
  • 3 large egg yolks
  • 120 g caster sugar
  • 60 g plain flour, sifted
  • 1 pinch fleur de sel or flaky sea salt

prep

  • 2 tbsp Dutch-process cocoa powder, for dusting

Method

  1. Preheat the oven to 200°C (180°C fan) / 400°F. Generously butter four individual metal dariole moulds or deep ramekins (180 ml capacity each). Dust with cocoa powder, tapping out the excess.
  2. Melt the chocolate and butter together in a heatproof bowl over a bain-marie (simmering water, bowl not touching water). Stir until completely smooth. Set aside to cool for 5 minutes.
  3. In a large bowl, whisk together the eggs, egg yolks, and caster sugar until the mixture is pale, thickened, and tripled in volume: about 4 minutes with an electric whisk.
  4. Pour the cooled chocolate mixture into the egg mixture and fold gently with a spatula until just combined. Sift in the flour and fold again until the batter is smooth and no flour streaks remain. Add the sea salt.
  5. Divide the batter equally between the prepared moulds. At this point the fondants can be refrigerated for up to 24 hours.
  6. Bake for 10–12 minutes (12–14 if coming from the fridge) until the edges are set and slightly pulling from the sides, but the centre still has a defined wobble when gently shaken.
  7. Run a thin knife around the edge of each mould. Place a warm serving plate upside-down over the mould, then invert in one confident motion. Leave for 10 seconds, then lift the mould. Serve immediately.

Notes

Serve with a small scoop of vanilla ice cream or a spoonful of crème fraîche (the temperature contrast against the warm chocolate is essential. A dusting of icing sugar and a few fresh raspberries are classic accompaniments. If the fondant collapses, it was overbaked; if it doesn't set enough to unmould, it was underbaked) adjust your oven temperature accordingly on subsequent attempts.
