Sinful Chocolate Truffle Cake - cooking recipe

Ingredients

14 ounces semisweet chocolate (I use Ghiradelli bar chocolate)
2 ounces unsweetened chocolate (I use bakers)
1 cup butter (do not use margarine)
9 large eggs, separated (you use both the yolk and whites)
1/2 cup sugar
1/4 teaspoon cream of tartar
confectioners' sugar (for dusting)

Preparation

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).
Replace bottom of pan in springform.
Grease and flour bottom and side of pan.
In heavy 2-quart saucepan, combine semisweet and unsweetened chocolates and butter and melt over very low heat, stirring frequently until smooth.
Pour into a large bowl and set aside.
In another bowl with mixer at high speed beat egg yolks and sugar until very thick and lemon colored, about 5 minutes.
Then add the egg yolk mixture to the chocolate mixture, stirring with rubber spatula until blended.
In another bowl with clean beaters, beat a high speed the egg whites and cream of tartar until soft peaks form when beaters are lifted.
With rubber spatula fold beaten egg whites into chocolate mixture, one third at a time, make sure you fold not stir.
Pour batter into prepared pan, spread evenly.
Bake for 35 minutes.
DO NOT OVERBAKE Cake will firm up while standing and chilling, it is a truffle cake not a standard cake.
Cool cake completely in pan on a cake rack.
When cool refridgerate overnight in pan.
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.
Refrigerate cake and remove 15 minutes before serving.
