I've messed up again! I am trying to bake for a charitable org sale tomorrow & I'm stressed to the limit. I sprayed my 8" pan but didn't think I would need it parchment lined. Is there anyway to unstick this mess? Thanks again.

try freezing it......sometimes cakes and cookies will shrink slightly when frozen, may be just enough for you to smack the pan on the counter (gently) and get it to free itself.

Thank you, I'll "try" to remember that for my next disaster. Too late this time, it came out in 5 pieces. Thanks.
