Prepare cake pans with Pan Grease Preheat your oven to 350° F **For those of you who cannot get buttermilk, well...you can make your own! Just add 1T white vinegar (or lemon juice) to 1 cup of milk and let it stand at room temp for about 15 minutes or so. It will get nice and thick like buttermilk with that zingy tang that buttermilk delivers! OR- if you have yogurt or sour cream you can interchange the buttermilk with that as well.
