id. I took my favorite chocolate cake recipe and subbed part of the water for champagne which gives it a subtle champagne flavor that I love. Enough to taste but no too much to take away from the chocolate. The filling is a vanilla champagne buttercream and the outside is a super silky chocolate buttercream (which you could also add champagne to, if you're feeling extra boozy). I can't think of anything more festive to eat while waving goodbye to 2016.
