I also struggle with air bubbles on my cookie surfaces, but aside from air bubbles, I cannot seem to get an even/smooth/uncracked cookie surface. Can anyone share advice or a possible cookie recipe that creates a nice smooth cookie surface? I have tried a sugar cookie dough as well as a shortbread dough, and the shortbread dough produces air bubbles, while the sugar cookie dough seems to crack or create ridges on the surface. Is this just normal? Is there a certain technique necessary to get a very nice smooth surface? Thank you!
