I picked up some black glassine cupcake cups and each one is separated by a white thin cup. Sad to admit, that I don't know if this is just to separate them, or do I bake with the white one on?

most likely it's just to separate them... like the foil liners.

I bought foil ones a while ago, and I have to admit, I did wonder the same thing. Glad it wasn't just me!

I always keep the white liner inside of the foil liners. They bake up fine!
