Does it exist? My son has asked for a sinple yellow cake with vanilla frosting for his 14th birthday. I'm good on the cake, which uses lots of yolks, and I'd like to use the leftover whites in an italian buttercream, but every recipe I can find calls for tons of butter. I know I've made one that didn't have that much butter in the past, but have lost the recipe.
We're also a minimal frosting family--just a scrape thru the middle, around the sides and over the top does it, so would appreciate a recipe that can be frozen if we don't use all of it, or reduced without affecting quality.
