Ingredients:
* 3 large eggs
* 3/4 cup white sugar
* 4 ounces semisweet chocolate, chopped
* 1 stick (1/2 cup) unsalted butter
* 1/2 cup cocoa powder
* pinch of salt
* 1 teaspoon vanilla extract
Preparation:
Whisk the eggs and sugar together in a mixing bowl for 2 minutes, or until light and foamy. Put the chocolate and butter in another bowl, and place over a saucepan of simmering water until both are melted. Stir to combine.
Add the chocolate mixture to the egg mixture, along with the cocoa powder, salt, and vanilla. Whisk until everything is combined. Grease an 8-inch round cake pan, and dust well with cocoa powder. Pour the batter into the prepared pan.
Bake in preheated 300 degrees F. oven for 30 minutes. Remove and let cool in the pan for 15 minutes. Invert onto a wire rack and allow to cool. May be dusted with additional cocoa powder if desired. Refrigerate until ready to serve.
