I can't wait to try it

MsMai,

Your Sour Cream-Nutmeg Sugar Cookies are to die for ~

Instead of sour cream, would it be okay to use plain yogurt?

The fat content of the yogurt would not be as high as sour cream and so your final result would be different, but heck give it a try and see what you get!

Will do. I'll let you know what happens.

Thanks.
