How to remove brownies cleanly from silicone molds? I've recently started looking into making brownies inside silicone molds (in particular, this guy) and I've noticed that it doesn't seem to matter whether I grease, grease &amp; flour, use pam, use parchment paper (with and without grease) or do nothing: the brownies are never guaranteed to come out cleanly. Each method yields some brownies that cleanly separate, with others that lose varying degrees of their bottoms to the pan.

Note: with parchment paper, the problem of a clean release just gets kicked down the road to the stage when I peel the paper off the brownie. Most of the time, the paper pulls a non-trivial amount of crumb off with it. 

What's the best way to insure a perfect removal of the brownies from silicon bakeware?
Freeze the brownies in the mold. They'll release cleanly.
