There is nothing special about this sheet cake recipe except that it turns out perfect every time. I've been making it for 20 years and it is always awesome. You can even mess with the ingredients and substitute skim milk and vinegar for the buttermilk and it's still awesome. And the frosting? Oh, baby, the frosting.
Here's the cake right out of the oven. Yep, that's a toothpick test hole right smack dab in the middle. The whole cake is actually a little uneven. I blame it on the oven, which is uneven. That's because our kitchen floor is uneven. Heck, our whole house is uneven. You couldn't find a 90 degree angle in this place to save your life. Don't worry. That's what frosting is for.
See? It's the miracle of frosting. Now everything is nice and even. You can frost this cake hot or cold, very handy if you're having a major "I need it now!" chocolate cake craving. Waiting is overrated.
Nothing, and I mean nothing, beats a piece of this cake, still warm from the oven with the frosting all soft and melty with a big glass of cold milk. If you're not drooling by now, there is something seriously wrong with you. I only used a half-recipe of the frosting. If I used a full recipe, there would be an equal amount of cake and frosting. And my butt would be as big as Rhode Island.
