Cute idea! What process do you use to do something like that? So the clear outer portion is supposed to be a shot glass and somehow you were able to keep the "chocolate" separate? This has promise.
I bought a silicon shot "glass" baking mold from Michael's and poured clear M&P with Peppermint EO in the mold. Once it came out, I mixed up a little more M&P, added peppermint EO and some cocoa powder, and poured into the "glass." Then I whipped regular M&P with a little liquid castille soap (found a recipe on Soap Queen) and shoved it in a baggie and snipped the end off to pipe on top.
Piping soap is something I want to try, because I love making cakes and things - I just have to get a cheap set of 4 tips from Walmart, cause I'm not using my good baking stuff with the soap. This seemed to work for now.
I think it needs a peppermint stick though, so I'm going to try and pour M&P mixed with white down some straws and paint on red lines later.
