what are best cupcake liners?
Grease-resistant or greaseproof or foil.
Reynolds StayBrite liners have gotten excellent reviews in every post I've seen. They are, of course, more expensive.
Bakers that deal with larger volume sometimes stay with the dark brown, greaseproof liners and buy in bulk.
What Apti said.
I get bulk greaseproof brown liners from thebakerskitchen.net
