I’ve seen people do both: two wrappers, but I think that was more to add a contrast of color-but whatever works. Have you tried grease proof liners?
I purchase the white, freestanding liners (in bulk), the ones that look like nut cups and those work well. Probably because they are thicker, just make sure you don’t order the Wilton kind because they aren’t meant for baking. I really
Iike the liners I use but am considering switching, sometimes (smaller children mainly) have a difficult time removing the thick liners.
Sorry, a bit of rambling
