Also like...my mother-in-law's shortbread christmas wreaths, merangue (made with egg whites, sugar, chopped walnuts, and choc chips), and jewel cookies (a shortbread-like cookie rolled in nuts and filled with jelly).
Oh...and I also like the one's with a Rollo baked in the center. A co-worker of mine makes them each year! Yum!
