I want to make my little girl's birthday cake at least one day in advance so I have time to decorate it and not be in a hurried rush trying to pipe like a maniac the day of. I have to work the day before though and doubt I could get all the baking and frosting making done, as well as coloring the frosting, and then decorating the cake (and her smash cake too). I'm using a box cake mix and Wilton's whipped icing to ice and decorate both cakes. Could I make this two days in advance? And how would I store it? I have kept that frosting for a good week in a tightly sealed container in the fridge and it did great. I just wasn't sure about having it already on a cake and decorated. Should I get a Wilton cake carrier? Or would that not be airtight enough? I can probably wrap the smash cake in foil. I assume they will both have to be refrigerated to keep the icing from going soft/melting the piping. Thank you!!!
I made a cake a few weeks ago that ended up sitting around for a while. I made it Friday night and it was supposed to be picked up Sunday. Due to unforseen circumstances, my friend couldn't pick it up. I took it to my in-laws Sunday night and it was still very good. They then served the leftovers to guests the next night and said it was still good. Mine was boxed red velvet cake with boxed cream cheese icing. It was a barrel cake, so not fancy icing decorations. I just put it in a cardboard cake box and left it in the fridge. They last longer than you think...especially when they're not cut yet. Two days in advance should not be a problem at all!!
Bake the cake and double wrap in plastic wrap, store in the cake box until you are ready to ice/decorate. it will be fine.
Unless your cake has a filling that has to be refrigerated, don't refrigerate cake. It will dry it out. (It's a relative humidity thing in the fridge.)
An iced cake will last 5 days (easy) on your counter. In fact, I'm sure you've bought 4-5 days old cake and the bakery many times. You just didn't know it. The "cake ladies" of past years always said that cake is BEST on the third day.
Thank you to all! And to leah_s, it does have a filling, but it's just cooked down strawberries/sugar/cornstarch so I'm pretty positive it will be fine. Thank you again!!
