I tried about three recipes for both the chocolate and the vanilla cake to find one that was soft, moist and fluffy. I decided on the basic chocolate and vanilla cupcakes from VCTOTW although the Vegan Lunchbox recipe made a really tasty cake, too.
I doubled both of the cake recipes and added three teaspoons of peppermint extract. The icing is a chocolate mint buttercream icing and the top of the cake has Green & Black's peppermint chocolate squares. I shaved some of them and sprinkled them over the top. My mom actually decorated the cake since she used to do them when I was a kid.
If you'd like to see some of the other stuff I've taken, I have pictures posted on my Flickr
