Preparation

Chef’s notes

Red wine chocolate cake, mocha chocolate cake:
You could replace the buttermilk in full with yogurt or sour cream thinned with a little milk or water, with red wine or replace 1/2 cup of it with strong coffee. (Keep 1/4 cup buttermilk so you’ll have an acidic ingredient to wake up the baking soda.)
I don’t have Dutched cocoa:
Dutch-process cocoa differs from natural cocoa in that its acidity has been neutralized to form a darker, nuttier cocoa that I prefer. If you don’t have Dutched but only a regular or natural cocoa, the cake may be less dark in color.
How I like to swirl frosting:
I always use a small offset spatula and the secret is to always push the frosting from the center out, not pull it back. So, push and then make an S-swirl, push and S-swirl, repeat and always quit while you’re ahead (hard, because it’s so fun).
Confetti sprinkles:
I got mine from New York Cake on 22nd Street but, of course, Amazon sells them as well.
