In one groupon class that I helped out with Chocolate martinis were made. I don't drink alcohol but they sure looked good I will post the picture at the bottom and a recipe since you may want to make it to. Vodka is strong so the creme and chocolate are a nice addition. They help smooth the alcohol out. It is important not to get to carried away though since you may not be able to walk straight after 4 of them.
Ingredients
4 oz. chocolate liqueur
2 oz. vanilla vodka
Splash of Half and Half
Chocolate syrup
