So in a week I am making a two tiered engagement cake for very good friends of mine. I want to make a layer Devil's Food and a layer White Cake. I have been trying some recipes off of MarthaStewart.com and haven't been sucessful. It seems like no matter what the cakes are dry! I do not overbake them so that is not the cause. Does anyone have any really good moist recipes for Devil's Food/Chocolate and White Cake???
HELP!!

I think you mean two teir. I suggest Blue Ribbon White cake, it's a recipe here on CC and it is very moist. My absolute favorite chocolate cake is from foodnetwork - http://www.foodnetwork.com/recipes/40-a-day/chocolate-fudge-cake-with-vanilla-buttercream-frosting-and-chocolate-ganache-glaze-recipe/index.html

And just a suggestion, you will save yourself a bit of work if you fill both cakes with the same filling. Choose something that goes well with both, such as raspberry
