my buttercream is not sticking to the cake
Could it be the cake itself? did you have it in the fride or freezer, prior?
If your BC is too thick it may not stick and if the cake is frozen it may not stick. Without knowing what you're working with it's hard to say.
Hey guys... sorry i had kids in each hand... I made the buttercream.. as I always do... but this batch seems to be rolling off the cakes... can i fix it by adding more butter maybe... I made it yesterday.. can i throw it back in the mixer and add more now?
How stiff is it?
Did you crumb coat the cake? If not, that might help it adhere.
