Chocolate Cake with Chocolate Buttercream Frosting - 1. Chocolate flavor. This cake, loaded with it. The boiling water intensifies the chocolate flavor of the cocoa. I’m starting to think it’s a must for all chocolate cakes. #2. Moisture. We all hate dry cakes. I like mine really moist. This one, check. #3. Crumb texture. Is it soft? Is it fluffy or dense? Does it have stability?
