I read a post where the poster said she melted her buttercream and poured it over her cake. She said she would post a picture. Now I can't find the post. Is this a thing? Where can I find out more info about it?
I've done that a time or two. It's sometimes called poured fondant. It's used when you want dribbles down the side of a cake.
Erica Obrien has done this. https://www.instagram.com/p/9gm9z_Hxmz/
