Making a grooms cake out of 4- 9x13's (it will be 9"x26"x4"), covering it with fondant and decorations.... I've gotta cook the cakes today so i can do all the decorations tomorrow since i don't have time on friday to do anything.... can i just use box mixes from the store, are they too moist?

(half my problem is deciding what flavor)

or does any have a recipe they would suggest since i'm doing the actual baking 3days out

Box mixes are fine...just be sure they are good and cold when covering with fondant.

Box mixes are great. Just make sure the cakes have cooled completely like KiddieKakes said.

Of course you can use a box mix.

Like everyone said, it's definitely fine. You will recognize that a lot of people here in CC use straight box mix. It's just the matter of support.

Thanks, I rarely use box mixes, (well except for one special recipe) but i'm short on time so can't do homemade, so i guess thats why i was nervous.... can't wait to post pictures of the finished cake, its for a wedding, calling it the grooms cake so it doesn't upstage the wedding cake too much, but its for both of them, and they don't know what its going to look like!!!!

I use box mixes almost exclusively! I have scratch recipes and custom flavors, but most people order the same ole vanilla, chocolate, etc. and there's no better way to save money and time then by using a good quality box mix!

I always used boxed cake mixes. Duncan hines and Pillsbury seem to hold up the best. Baking two days ahead is usually my schedule especially if they are to be covered with fondant.
