When I make sugar cookies, I roll them to even thickness but when I cook them little and big bubbles appear why? And they don't go away.
Which cookie recipe are you using? I use the NF recipe and rarely get bubbles. If I do, I "smooth" the cookie with the flat side of my cookie spatula as soon as they come out of the oven.
I'm using a sugar cookie recipe out of a book.
2 t vanilla
2 1/2c. flour
1 egg slightly beaten
I've occasionally gotten a large bubble on a NFSC, but if I catch it right away, I can pop it with a knife/toothpick/skewer and smooth it back down when it first comes out of the oven. I don't know how to avoid this as I'm not sure how the bubbles get in there to begin with.
I have this happen occasionally as well. Have not been able to pinpoint exactly why. Sorry I can't be more help!
this happen to me today also. i think i am able to cover up with my icing, well see when it all dries. glad to know not just me!!
try adding 1 t. of baking powder and see what happens
Too much moisture in your dough. Add another 1/2-3/4 cup flour and you should be alright. I wouldn't add any baking soda/powder, though. HTH
