I'm making my boyfriend a cake for his birthday, but because I lack any sort of electric mixer (and am reluctant to purchase one since I'm a student and saving money is preferred), I'm wondering if it would be okay to use a store-bought icing underneath the fondant. My main concern is if it will harden up enough so the fondant won't slide around.
Some grocery stores will sell buttercream out of their bakeyr departments. I can't really say about canned frosting as I have never used it.
I wouldn't use canned frosting under fondant. Go to Target and spend 5.99 and buy a cheap hand mixer. I bought one for a back up. I have two hand mixers saved time washing beaters when I'm in a hurry. It's cheap but it gets the job done.
i have put fondant on a cake that my neighbor brought over and i know for a fact she doesn't make any frosting ...its all canned or purchased at a store such as wilton ready made or a bakery frosting. it has always worked fine.
