Chocolate Baumkuchen
(Some people make this flat and roll it up like a log, I prefer it made in a springform pan like a regular cake. Whatever you prefer, this is a very dramatic and excellent cake)
Melt 1/3 cup of the chocolate, cool, Beat the butter, 1/2 cup sugar, and vanilla until light and fluffy. Add the egg yolks one at a time, mixing well after each one. Add in the flour and starch, divide the batter into two portions, add the chocolate to one portion.
Beat the eggs until soft, add 1/4 cup sugar, beat until stiff. Fold half into each of the batter portions.
Turn on the oven broiler to heat the oven.
Pour a very thin layer of the chocolate batter (no more than 1/2 cup) into a 8 inch springform pan. Broil for one to two minutes until it is cooked. Alternate layers of the light and dark batter, cooking under the broiler for each layer. Make sure the pan is far enough away from the heat to cook each layer through, and keep an eye on it, two or three seconds is all it takes to go from done to burned. Continue until you have used all the batter or filled the pan.
Mix the sour cream, 3 Tbl sugar and lemon juice as the top layer, spread on top and broil one minute. (note - as a very pretty decoration you can place several cookie cutters on top of the cake and spread most of the sour cream layer around the outside of them. Color the remaining layer using food coloring, and fill the cookie cutters with the colored mix, then broil to set (of course, make sure you are using heat proof cookie cutters))
Frost the sides with chocolate butter cream frosting, or use the chocolate Sour Cream buttercream frosting:
8 oz semi sweet chocolate
3 T butter
1/3 cup sour cream
1/4 t vanilla
2 Cups conf sugar
Melt the chocolate and butter, cool. Add sour cream and vanilla, mix well, add sugar until it's the desired consistency.
