Another recipe from a blog I'm rather fond of, peppermint bark fudge is delicious and incredibly easy to make. I made a batch as a Christmas present for my grandparents, the little I ate of it was delicious, and also made a peppermint-free batch for the mint hater I live with. I couldn't believe how rich and chocolaty it was, considering how little time it took to make.
My only recommendation would be to line the pan that you use to chill the fudge, as even when chilled overnight the stuff is rather sticky. After prying the fudge out of the pan, I wound up dusting the bottom with powdered sugar so that the pieces in the box I was giving as a gift wouldn't stick together.
