The fudge wreaths came out great! They were beautiful and tasty.
Instead of wrapping the can in plastic wrap, I sprayed it with Pam after removing the label. That worked perfectly. I also used a springform pan, so transferring the wreath from the pan to the plate was quite easy. Also, I didn't put it in the fridge to cool, I just left it on the counter until it was firm.
I imagine that you could apply this technique to any fudge recipe. If I have enough ingredients this morning, I'm going to try it with the Never-Fail Fudge recipe for my family. (We gave the other wreaths away to neighbors.)
