I'm making up my cake mix, but I don't want to actually bake the cake until tomorrow as it's for a wedding on Saturday. Is it ok to leave the mix, prepared, and covered in the fridge over night?

sorry, I don't know the answer but I would like to!!!

I wouldn't. I doubt the leaening will work and you'll end up with a flat cake when you bake it.

A tightly Saran wrapped and Zip-locked cake will be fine for an extra day. Or throw it in the freezer - I've started baking most of my cakes ahead and freezing for a couple of days so I don't have to worry about my time management.

not a good idea. once you mix the batter it should be baked right of way so it rises properly. if it sits overnight it won't rise properly leaving you with short cakes.....

If I were you, I would bake it and freeze.

go ahead and bake it. Cake keeps so well. I always have my ckes for the weekend bake by Tuesday. I just vacuum seal and freeze. I have done that as far as a week ahead to rave reviews.

If it's a box-mix, it only takes less than 5 minutes to mix one up, so you're not really saving that much time in exchange for the potential problems it could bring.

someone here on CC actually tried putting the cake batter in a cake pan and then freezing that. i think she then thawed it to room temp and baked. she says it didn't differ much from the batch mixed and baked on the same day. i haven't tried it myself but i will try it one day.

I did this ONCE
When the cake mix came to room temp it was the oddest shade of a yellowy whiteish kinda gray blob. (it started out as a white cake mix) I put it in the pan, baked it and it did not rise and was gummy. Never again It takes 5 minutes to whip up a mix.
