This tray is perfect for making bite sized Whoopies, and you can get 12 out of one tray. Spray each hole with oil and the Whoopies fall out easily. A really solid tray, the non-stick coating is excellent. I ordered just 1 in case it wasn't good, just ordered another as I was washing and re-using this all the time.
Tried macarons today: it's not good for them, the 'feet' go up the side, and they stick pretty badly too.
So stick to re-usable greaseproof for macarons, but this tray is fantastic for Whoopies!
