This is more of a candy than a cookie, but great for Christmas, and little kids can help (mine started at age 2 placing the Herhsye's kisses)
Reindeer Noses
need: waffle pretzels (the square ones), Hershey's kisses, and red M&M's
heat your oven to the lowest setting. Lay out pretzels on a cookie sheet in a single layer, place one kiss on each pretzel. Heat in the oven about 5 minutes until the kiss is soft (test with the end of a wooden spoon). Pull them out of the oven and quickly put a red M&M on top of each and squish it in just a little - it looks like Rudolph's nose on his furry brown muzzle! But get them on quick before the chocolate starts cooling or it will crack when you push the candy in.
My boys (7 and 4 1/2) LOVE making these every year for everyone they know. They started out just laying out the pretzels and placing kisses, but last year the then 6 year old was great adding M&M's - it was a little messier for the 3 year old, but he loved trying!
