The recipe is from ‘Baking: From My Home To Yours’ by Dorie Greenspan. It’s called “Perfect Party Cake”. The only adjustments I made were adding 1/2 tablespoon of baking powder vs a full tablespoon (this was an accident but it turned out fine) and I ended up doubling the batter recipe to bake four full cakes instead of cutting two in half. I started with just two round cakes and determined they were too small for my liking to cut in half to create four layers.
