Flourless chocolate cake

Best chocolate cake ever, from Sue Bell:

Melt together:
1/4 cup of unsalted butter
6 to 7 oz bittersweet chocolate

Grind together:
    1 cup of nuts (hazelnuts, pecans, almonds) with
    1 cup of sugar

Add:
    1 teaspoon vanilla   
    6 eggs (I usually separate some and whip the whites, then fold them into the batter.)

You can make the whole batter in a cuisinart.  First grinding nuts, adding sugar, then the choc mix, then vanilla and eggs. 

Bake at 350 degrees for about 40 minutes in a paper-lined 9" or 10" pan or a buttered flan dish.

If you want to cover it with chocolate, melt 3 to 4 oz chocolate with a tablespoon of butter and pour it on while it is still warm.
