Accidental success! I still have not mastered estimating how much Bettercream to whip - so orignal plan was to add choc. syrup for the filling for this choc. cake. I whipped SO much I just went ahead and frosted the whole cake with it. My MMF poinsettia leaves and berries were very bright (originally planned on a white frosting) so I toned them down a little with liquid pearl, brown gel mixture and painted on. The look is very muted and actually doesn't look too bad.
