Ingredients

  • 18 tablespoons (255g) unsalted butter, cut into pieces
  • 8 1/2 ounces (250g) bittersweet chocolate (preferably Guittard Quetzalcoatl 72% cacao), chopped
  • 5 large egg yolks
  • 5 large eggs
  • 1/2 cup plus 2 tablespoons (125g) sugar
  • 1/3 cup plus 1 tablespoon (50g) all-purpose flour
  • Chocolate Sauce (page 268)
  • Chocolate Crumble (page 213)
  • Vanilla Bean Ice Cream (page 220)
  • Crystallized Vanilla (page 186; optional)
  • Confectioners sugar (optional)

Method

  • Butter eight 4-ounce ramekins or sixteen 2-ounce molds and dust them lightly with flour.
  • Set the ramekins on a baking sheet.
  • Put the butter and chocolate in a glass bowl and melt in the microwave, using 30-second bursts.
  • Stir until smooth.
  • Put the egg yolks and eggs in the bowl of a standing mixer fitted with the whisk.
  • Beat at medium speed until frothy.
  • Pour in the sugar and increase the speed to medium-high.
  • Continue to beat until the eggs have tripled in volume.
  • Scrape the butter and chocolate into the eggs.
  • Beat until well mixed, scraping the bowl once or twice.
  • Sift the flour over the batter and fold it in gently.
  • Put the batter in a pastry bag and pipe into the ramekins.
  • Cover with plastic wrap and refrigerate until youre ready to serve the dessert or for up to 8 hours.
  • Take the cakes out of the refrigerator to bring them to room temperature.
  • Heat the oven to 475F or 450F on convection.
  • Slide the baking sheet into the oven and bake the cakes until the sides and tops are set, about 4 minutes for small cakes or 6 to 7 minutes for large ones.
  • The centers will still be very soft.
  • Invert the ramekins onto dessert plates.
  • Leave for about 10 seconds, then lift off the ramekins.
  • Spoon a little chocolate sauce around each cake.
  • Make a small pile of chocolate crumble to the side, and top with a scoop of ice cream.
  • Garnish the ice cream with crystallized vanilla and the cake with confectioners sugar, if you want.
  • Serve immediately.
