I made this today and it turned out wonderful! Someone at the party actually said, "This is one of the best cakes I've ever eaten." So the name is appropriate.
I did alter the recipe somewhat.
* Instead of creme d'menthe I used peppermint extract and water (some sources said I could use grapefruit juice in place of water)
* I took everyone's advice and used chocolate cake rather than white.
* For the frosting I used 1 tub cool whip, 2/3 cup sour cream, 1 cup powdered sugar, peppermint extract, green food coloring.
* I piped melted chocolate for the greeting and dots. If this wasn't going to be for a party I would have made lines on the top like this cake. (Which, btw, I've made several times and looks and tastes wonderful too. That's also where I came up with the idea to change the frosting.)
So hats off to you Friend Traci for introducing us to this great recipe! It's a keeper!
