This cake was what I chose for our family's Valentine's Christmas (we put it off until after a baby in the family was born so that all the travelers could meet the baby). We didn't have peppermint extract, so I used almond extract instead. So half the batter was made with the almond extract and the other half was made with cocoa/sugar and spiced rum. My 4 year old loved helping with the kitchen aid and doing the marbling effect!
This cake was not too difficult, good tasting, and could be done with a few different variations. Next time I think I'll skip the green food coloring and it'll be a brown and white colored cake.
