Chocolate Flourless Cake Recipe

Melt the chocolate and butter over a bain marie (double boiler).

Whisk the yolks into the melted chocolate. Whip the egg whites until shiny. Add the sugar and whip until very stiff. Fold into the chocolate.

Pour the batter into a full size hotel pan that is lined with buttered parchment. Bake at 400 F (200 C) for 10 minutes.

Reduce oven temperature to 350 F (180 C) and continue baking until done, approximately 40 minutes. A cake tester will not come out clean, even though the cake will be done. Invert the cake onto the back of a sheet pan. Cool completely; then dust with powdered sugar.
