My daughter asked for a Paw Patrol bone shaped cake for her birthday party this Saturday. I plan on making in since it looks fairly simple, except for all the cakes I have to make for it.  I really don't want to spend all day Friday( which is her actual birthday) baking, decorating, then going and meeting out of state family members.  So would it be possible for me do some of the cakes tomorrow( Thursday) and then the rest on Friday with the decorating or bake all the cakes tomorrow and then decorate on Friday? 

I would bake tomorrow, and finish it Friday night for Saturday. If you don't want to do them all tomorrow, baking some tomorrow, and the rest Friday would work, too. I personally like to have all my baking done the same day so I can focus on the decorating. 

Thank you. That's kinda what I was thinking, I always do them the day before and then decorate that night. With this one being so big, I wasn't sure how it would hold up since it won't fit in the fridge. 

I've seen that cake, and it looks to be a big size. As long as you don't have any perishable fillings in it, it will be perfectly fine on the counter. 

Yes, you can bake Thrusday or even today if that works:)  Just wrap it in plastic wrap or put it in a plastic bag.    Don't know what yhou are calling 'big' but to make what I think you are going to make all you need are four 6" rounds (or smaller if you have the pans) and a 6" sq or 7x11 sheet.  Those cakes should all fit in the frige w/o a problem or it can be left out.
