I live in a very remote part of the world where I cannot get butter, margarine, or shortening. Seems like almost every cake recipe in my cookbooks calls for ginormous amounts of butter. Does anyone have any tried and true recipes for cakes that use oil and not some kind of solid fat? I already have good recipes for a chocolate cake, an apple spice cake, carrot cupcakes, and a lemon yogurt cake, but would like to expand my repertoire. Thanks in advance!
