Chocolate Génoise Recipe

OK, I decided.

Chocolate génoise is the foundation upon which a great Black Forest cake is built, and is good for a number of other things besides. Like a classic génoise it’s rather dry, but then it’s whole reason for being is to be soaked liberally with syrup.

4 tablespoons unsalted butter
3.5 ounces (3/4 cup) cake flour
0.75 ounces (1/4 cup) Dutch-process cocoa
1/2 teaspoon salt
6 eggs, room temperature
5.25 ounces (3/4 cup) sugar
1 teaspoon vanilla extract
