This cake is a nightmare. I have to do a bee design logo for a team, I was going to do it in buttercream and place it on the cake, but will it bleed/ sink in? Is there anyway I can do it so the cake is still mainly whipped cream? Maybe a butter cream circle in the middle?

I was going to suggest a buttercream base under your picture, so you're on the right track! If you put color on whipped cream, it will most definitely bleed.

Thanks! I did a square base in butter cream for it! Gonna wait to transfer until the whipped cream is chilled enough.
