Notes

  • If you’re not using 6-inch pans, double the recipe for 8-inch pans or triple the recipe for 9-inch pans.
  • You can substitute whole milk yogurt for the sour cream if desired, I do it all the time and can’t really tell the difference.
  • To get FLAT layers that are moist inside and out try using cake strips! You can buy a set on the shop page or make your own from foil and paper towels at home. I made a whole blog post on it so check it out if you’re interested!
  • If you don't want to make Italian buttercream you can use the American variety. I just prefer the smoothness and taste of the Italian variety. I know it's a pain to make two different types of frosting though!
