A cinnamon roll should have no cum nor frosting on it.

Sincerely, Certified Swede and cinnamon roll authority

I’m not sure you know how dry and bad cinnamon rolls can b e in North America and how badly they need that frosting. The cum is optional.
But frosting them is just making up for one mistake with another mistake
you swedes want your cinnamon rolls dry so you can add fresh cum on it before use?
