I have been making cakes and covering them with fondant, and I have been having a problem with the cakes being too moist and crumbling. What do you think is the best kind of cake to bake when using fondant? Lol, I'm making a tiered first birthday cake for Sunday and I would hate to see it fall apart.
You need a somewhat dense cake to use fondant so it can stand up to the extra weight. Pound cakes are good, and there are some other good recipes on this site. Using the mix extenders are good because they have extra flour and sour cream which can help.
Try the WASC recipe. Also, if your stacking your cakes, make sure you have proper supports.
What recipe are you using? I've covered straight box mix cakes with fondant before without any problems.
My favorite recipe is kakeladi's original WASC recipe. I've tried some of the other WASC recipes but they were too wet and moist for my liking.
