THIS. This is the recipe I have been searching for! This yellow cake is ridiculously delicious, bakes up beautifully and is delightfully moist. Thanks to Deb over at Smitten Kitchen for sharing this recipe! You can get two 9-inch round, 2-inch tall cake layers, 24 cupcakes, two 8-inch squares or a 9×13 single-layer cake. Cake flour substitution: Simply place 1 tablespoon corn starch in a measuring cup and fill the remainder with flour. Level and sift...it works perfectly!
