Mon gateau au chocolat

Serves 8 to 10.

12 oz of bittersweet chocolate (preferably Lindt or Tobler)
2/3 cup of unsalted butter
3/4 cup of granulated sugar
5 large eggs, separated
1/3 cup of unbleached all-purpose flour
2 tsp of confectioner’s sugar for decoration

  • Preheat oven to 350°F.
  • Butter a 9-inch springform pan.
  • Combine the chocolate, butter and granulated sugar in the top of a double boiler placed over simmering water.
  • Melt over medium heat, stirring until the ingredients are blended.
  • Set the mixture aside to cool.
  • Whisk the egg yolks into the chocolate. Whisk in the flour.
  • Beat the egg whites in a large bowl just until they form firm peaks; do not overbeat.
  • Add one third of the egg whites to the chocolate batter and mix vigorously.
  • Gently fold in the remaining whites. Do not overmix, but be sure no streaks of whites remain.
  • Pour the batter into the prepared pan. Bake until cake is firm and springy, about 35 to 40 minutes.
  • Cool on a rack for several hours before unmolding.
  • This cake is traditionally served without icing. But, you may dust it with confectioner’s sugar for a finishing touch.
