Transfer to a larger tray or plate and allow to cool.
You must organize like this - you have to have two baking sheets. While one is in the oven, you prepare the other one. Remove the roses, wash and dry the sheet and prepare the next batch while the other tray is in the oven.
In the end, I had a big plate full of roses. I can assure you this is not a lot. The cookies will go so fast. Also, they are good even in a week's time, stored in a dry place in an airtight container.
