Quite dark and dry despite the irish cream and creme de cacao. Nice creamy mocha just lightly sweetened with a nice hit of bourbon on the finish. My wife took a taste of mine and stole it so clearly enjoyed by her as well.
Double (heavy) cream is easier to float, but whichever cream you use, the trick is to whip it or shake it to get air into the cream. Then pouring down the handle of a flat-end bar spoon is my preferred method of layering the cream over the cocktail.
