Also, if you've never baked a cake in your life, this is the perfect cake to start with. It's easy.
Some tips for cooking cakes in general that this recipe does not mention:
Before pouring your batter in a metal or glass baking pan:
Spray your baking pans with spray oil... Cover completely. If you don't have spray oil handy, you can dab your finger with cooking oil and thoroughly cover the pan that way.
Flour the pan after oiling it: Sprinkle a dab of flour into the pan and then shift the pan around until the flour totally covers the bottom and sides of the pan.
If you're using a silicon pan, well you're just too wise for your own britches.... (You don't need to oil and flour, but that's why you bought that pan.)
Don't try to frost a hot cake! You need to let your cake cool down most of the way before you try to frost it. If you try to frost a hot cake, you'll tear it up.
Don't try to catch a cake coming loose from the pan. Then you won't have a small repair job on your hands like I did.
