Ok, so... I made a cake this weekend with MMF. I crumb coated the cake with crusting buttercream and put it in the fridge to 'crust'.

But then when I put the fondant over the buttercream, it wouldn't stick. I was trying to smooth it on forever and tried re-applying it, nothing would work.

My fridge is set on super cold, I wonder if this was the problem?

Does anyone know what I did wrong??

thank you!

Sometimes with crusting buttercream you just have to give it a fine misting of water from a water spray bottle (doesn't take much) and the fondant will stick just fine.

I concur. I wait a couple of minutes after spritzing to let it soak in and to mop up any drips/drops that get on the board.

After my cake crust I use a pastry brush and brush on a thin coat of "glue" made with sugar and water. The fondant sticks to the cake with no problems.

ditto

When using fondant, you shouldn't wait for your BC to crust, otherwise it won't stick...

If my buttercream doesn't crust, I can't get it smooth.
If my buttercream isn't smooth, my fondant isn't smooth.
If my fondant isn't smooth, my cake looks like crap.

My buttercream must crust, therefore I mist with water when necessary.

I agree that if your buttercream isn't smooth your fondant won't be either.

I crumb coat and smooth. Then I do my "final" coat, smooth and wait to crust so I can use the viva paper towel to smooth it even more.

THEN finally on goes the fondant.

You are all right! Sorry! I chill mine so my BC is firm, pretty much the same as crusting...sorry!!

In the Wilton class they told us to brush a line of piping gel about 1/4 inch up the from the bottom of the cake.

I just crumb coat mine, smooth and chill for about an hour and never had a problem with it sticking.

Thanks everyone! I'm going to try those techniques, I'm sure they'll work great!
