Buttermilk Coconut Cake
To use one 13x9x2-inch baking pan, bake for about 30 minutes or until cake tests done. Cool cake completely and spread with Butter Frosting, refrigerating any leftover frosting, or use a smaller frosting recipe.
To make sour milk, place 1 tablespoon lemon juice or vinegar in a glass measuring cup. Pour in enough milk to make 1 cup liquid. Stir and let stand for 5 minutes before using.
