Nana calls 'em crescent cookies, and they're also known as Rugelachs. They're made with a cream cheese dough; rolled out thin; filled with sugar, cinnamon, and crushed nuts; and then dusted with powdered sugar after baking.
They're a Christmas tradition in the Jinx household and get mailed out in Christmas packages to family members all across the country!
Hum, might try something like that with regular crescent rolls.
