This is quite a project, but worth the time and effort when you want something extra special and chocolaty. Be sure to read the directions all the way through well before you intend to make this. The ganache needs to be prepared a day ahead of time and you may want to also prepare the glaze and decorations ahead as well, to save time and energy on the day of preparation.

CHOCOLATE GANACHE (needs to be prepared day before) Recipe makes enough for one 9" cake. About 1 1/3 cups.
Bring cream to boil in heavy small saucepan. Remove pan from heat. Add chocolate and stir until melted. Pour into bowl; refrigerate overnight.
Just before using, beat with electric mixer until just fluffy, about 5 seconds.

Sift 3/4 cup flour with cocoa and baking powder into medium bowl.
Whisk eggs and sugar in large bowl. Set over saucepan of boiling water and whisk eggs until warm to the touch. Remove bowl from over water.
Using electric mixer, beat egg mixture until it whitens and more than triples in volume, about 5 minutes. Mix in vanilla.
Sift dry ingredients again and gently fold into egg mixture until just incorporated.
Add butter and fold in until just incorporated; do not overmix.
Pour batter into prepared pan. Bake until cake begins to pull away from sides of pan and toothpick inserted in center comes out clean, about 20 minutes. Invert on cake rack and cool.
