Chocolate Oatmeal Chocolate Chip Cake

I've made this a few times, but can't remember where I found the recipe. I sprinkled almonds on top of part of the cake this time because I was in the mood for nuts and they were all I had. Sometimes I sprinkle powdered sugar on top or drizzle a glaze. Next time I think I'll even add coconut to the top. Since you soak the oatmeal in the boiling water, you can't even tell there's oatmeal in the cake. It's moist and chocolatey!
