Yes you can freeze your cake before or after crumb coating. I froze my cakes for my 50th wedding Anniversary about four days before making it and it turned out so fresh and very moist. I had made three tiers of Red Velvet cakes. I didn't crumb coat them first. I wrapped them really good in saran wrap and then into a plastic zip lock bag. They were great. I have frozen a complete decorated cake or cakes before with all butter cream and they were fine. I noticed on the cake boss and some of the other cake TV shows that they also freeze some of there cakes. I would not freeze a fondant one tho. I hope this helps you, Nancy of Rialto CA
