I have two birthday cakes to deliver by Saturday. One is chocolate WASC and one is regular WASC. They are both sheetcakes. (Children's parties!) Should I put them in the refrigerator (covered very well) until then or are they okay covered up unrefrigerated? I ask only because the recipe has sour cream in it. I'm thinking they're fine, but I want to make absolutely sure since these cakes are leaving my house. I know around here we leave cake out for days and it's fine.... but that's us. I don't want to take a chance on a child's birthday party being ruined!
Thanks.

Are they already decorated? If not wrap them well in Press N'seal Freezer wrap and put them in the freezer until ready to decorate.
They aren't decorated. I was going to do that tomorrow. Can I decorate them frozen (or while they're thawing out, technically)?

I freeze all the time to seal in the moisture and get rave reviews that my cakes are moist and have great flavor. After I take my cakes out of oven, I let them sit for 5 minutes, then turn out onto press n seal and put in freezer. When my partner gets ready to decorate, she takes them out and lets them sit for 5 minutes., then starts to sculpt/decorate. She has no problem and actually they are easier to handle. 
Yes! I'm finally done. They are easier to handle and I just may have found a new way of doing things. You don't have as many crumb issues. I froze them last night and worked/finished them today while they were still cold. Thanks for your help!
