Hi Carla, My mother always uses a metal press (from the 1970s) and she never oils or greases it. The butter in the batter seems to do the trick. In my experience the old metal presses are the best!

Thanks will let you know.

I added a 1/8 cup more of flour and chilled for 10-15 minutes before pressing. They get sticky when warm

Thank you all so much for the replies and tips. That makes perfect sense, I do believe the issue here was something related to the temperature. I left the unused cookie dough out while the different batches were baking, next time I’ll try refrigerating the extra batches until they’re ready to be used. I’ll also leave the sheets in the freezer prior to use. Thank you so much!!
