I use the cardboard "rounds" under the cakes to wrap and freeze them. Does anyone know if they make these in a plastic version so they would be reuseable? Or can the "rounds" be covered with something?
Thanks.

YES!! They do make plastic ones. Wilton makes them. I LOVE THEM. I use them for exactly this purpose. They are also great for flipping warm cakes out on, using for temporary boards, etc. They sell them in packs of 3 in various sizes, and they last 'forever'.
