I have done cakes for many years, but mostly for special occasions. I am working on my son's 3rd b-day cake for this Sunday. When I make cakes they never come out even and I have to cut the bump off the cake to make it level. I always had a hard time doing this. I watch Cake Boss and see them doing it all the time w/out issue. A light bulb went off in my head and i realized they freeze their cakes...this must the way they do it. So I did it. Now, I have 6 cakes (for a 3 tier stacked) that are frozen. It was really easy cutting the "bump" off the cake, but now that its defrosting I am wondering if I can go ahead and ice them? Do you think that will be a problem or do I need to wait till room temp? If so then I have a problem since i am pressed for time and I have to get these iced today. I will be using Wilton's buttercream icing.

Your cakes should be ready to ice within the hour. Frozen cakes take NO time at all to thaw, if that's your plan. HTH.

Wait for your cakes to thaw completely before icing them. If you ice a frozen or partially frozen cake it will take FOREVER for your icing to crust. You will get better results by waiting for it to thaw.
