Despite signs to the contrary, I'm not really obsessed with witches. Oh, I like them just fine (old-fashioned scary ones) but I also like a a nice scary bat, a cute pumpkin, or a spooky ghost. It just worked out that I made a bunch of witch cupcakes this year.
These cupcakes were made by piping a big dollop of swiss meringue buttercream (dyed green) for the face. Height is important - don't make a squished witch face! Decorate the face with more buttercream and a green M&M for the nose. The hair is made of edible Easter grass (again - you could use licorice or strips of fruit roll-ups). The hat is made out of a Fudge Stripe cookie with chocolate ganache piped for the cone of the hat. The buckle on the hat is made from more buttercream frosting.
Making the ganache is easy - heat one cup of cream and pour over two cups of dark chocolate or semi-sweet chocolate chips. Let it sit for about 5 minutes then stir to melt all the chips. You will need to let the ganache cool to good piping consistenc - too warm and the hats will flop over but too cold and the hats won't pipe out of the bag.
