Birthday Party Issue

I am a cake decorator. Unless it is really hot or extremely humid, your cake should be fine. If it's really hot or humid, it may get a bit weepy, but it won't go bad. If it's a cake covered in fondant, it is recommended NOT to refrigerate those. If it's butter cream, butter cream can sit out unrefrigerated for up to three days. If it's simply a matter of no place to put the cake while you bowl, stick it in a cooler, so it doesn't get bumped or knocked over (I wouldn't recommend leaving it in the car).

Is this an ice cream cake? I ask because that is the only cake I can think of that actually needs refrigeration. If it is an ice cream cake you can have a friend run it up, find the biggest cooler on earth and put in dry ice, family maybe?

Are you not able to put the cake in the room while you bowl? The cake should be just fine in there until you are ready to eat it - if you're able to put it in there. Or - how close will you be to your house? Could someone bring it closer to when you get to that part of the party?

Unless it's an ice cream cake, can't you leave it out? We always buy our dd's birthday cake in the morning and leave it on the counter until her party around lunch time. We've never had a problem.

I usually make my cake a week ahead and freeze it. I take it out a couple of hours before serving and let it thaw.

Use buttercream instead of whipped cream, and it doesn't have to be refridgerated.
