• Preheat oven to 300 degrees.
• Remove the bottom of a 9 inch springform pan and cover with tin foil, wrapping foil around to the back (this will make it easier to remove cake from pan).

• With rubber spatula fold beaten egg whites into chocolate mixture, one third at a time, make sure you fold not stir.

• In the morning to remove the cake from pan, run a hot knife, (run knife under hot water) around edge of cake, and unhook spring latch on side of pan and lift off side of pan.
• Invert cake onto cake plate, unwrap foil from bottom of pan and lift off bottom of pan.
• To decorate top of cake using a fine sieve, sprinkle with confectioners sugar, or I made a heart stencil with paper for valentines day and placed on top of cake to create a heart outline with the sugar.
