Have you seen the current trend of “naked” cakes? Essentially, cakes with no frosting or icing on the outside, only in between the layers. Here are some examples if you’re not familiar: https://www.theknot.com/content/naked-cake-designs
I don’t see the appeal, they mostly look sloppy and unfinished to me. Plus, I bet those cake edges get super dry, and nobody likes dry cake! If you’re a fan, what do you like about them?
