This is what I do. After it's covered, smooth the top first, then gently start with the corners first. Smooth the fondant down the straight edge of one corner at a time, working it down to the bottom. Do all four corners then start working the sides with your hands/smoother to get it on.

I always use a pizza cutter to cut off big sections of excess fondant so it doesn't weigh everything down and make it start tearing. Then cut the excess off around the bottom edge for a nice clean cut.

Hope that helps!

start with the corners first and the rest will practically fall into place on its own

thanks guys! You're always such a big help!

Isn't it Aine2 that has a tutorial on doing square cake with fondant? She makes it look so simple.

Just smooth the corners first, it really is just like doing a round cake.

I love her tutorial...think I may have the guts to try a square now, but I always ice my cake with buttercream as if I wasn't putting fondant. Do the rest of you all just add a crumb coat and then add fondant?

i agree with kimaz.. that is how i do them.. hth

Sugarshack also has a DVD on covering various shaped cakes, and she gives special attention to square ones. She also does the corners first and then smooths the sides in between the corners.
