If you are a peppermint fan-atic, this cake will quickly become a favorite! Perfect cake for Christmas get togethers, or anytime you have a hankering for chocolate and peppermint. Recipe from "The Cake Mix Doctor..." I think this cake tastes best if allowed to sit for about 24 hours to let the flavors meld. Passive work time includes cooling time for cake and ganache

We really did enjoy this cake. It was something a little different from the standard. It would be a great Christmas cake. Thanks for posting.

This is a fabulous recipe which I have been making for Christmas and other special occasions ever since the book came out. It lookes like a lot of steps but is SO easy! Dragonfly made a couple of changes, so I just wanted to mention the original recipe doesn't call for any peppermint in the cake mix - it's unnecessary since there's mint in both the filling & frosting. Also, the Cake Mix Doctor recipe says prepare one-HALF of the peppermint filling. (you only need to cover one layer with it - although I noticed Dragonfly suggest using the extra as a garnish). And in the ganache, you can use 1/2 tsp of the extract, or 1 Tbsp of the schnapps. Also, instead of letting the ganache sit for 4 hours, I stick it in the fridge for about 20 minutes. But however you choose to make the cake - enjoy!
