I need to cover ice cream cones with BC for a cake...do i need to apply anything on them before hand? What is the best possible way to get a smooth finish on them? Without indentations of the cone showing too much?

Hi, iv used buttercream to cover ice cream cones before, myne was on a castle tho so i wanted the ruffer look rather than smooth so the glitter sat in the indents.I found that aslong as the bc wasnt to think it would spread nicely and you dont see the pattern from the cone, i didnt use anything on the cone before hand either.

Hope this helps
