Can I place a royal icing collar on a buttercream cake? Thanks
I wouldn't. I've never made a royal icing collar but know from past experience that when you apply a royal icing plaque to the top of a buttercream cake, they suggest you elevate it up on sugar cubes that you've topped with royal to secure it because the one true enemy of royal is oils and grease.
That's what I thought, but wanted to make sure. thanks for your help!!
