I have to do a stacked square cake soon and I have problems with the corners! Any suggestions?

I love using a 6" spackle knife/putty knife thing from the hardware store....works great for circles or squares but helps alot with the squares.

tuitorials...there are many. BC, fondant, and ganache...ganache is my favorite for corners under fondant.
Blessings~

so how would I use ganache or bc fondant on corners and not have it stand out?

She only wants BG on the cake.

SeriousCake's has wonderful tutorials on Youtube, this one is about square cakes! HTH
