I want to frost a cake with RIch's Bettercreme whipped icing (mixing it up from the refrigerated liquid).
I have read that trying to color the Rich's Bettercreme icing does not work well, especially when trying to get vivid colors. So I would like to make buttercream icing, color the buttercream, and then decorate the cake frosted with Rich's Bettercreme. Can someone tell me if this would work? Would there be a problem with the buttercream decorations (piping around top and base) sticking to the Rich's Bettercreme?
