Mailanderli

1 lbs butter
1 cup sugar
6 egg yolks
1 T vanilla
5 cups flour

I also add the grind of 2 lemons to the recipes, but that is my preference.
1 additional egg for eggwash

Make dough using creaming method and chill. Roll out 1/4" thick and cut in shapes desired. Egg wash and bake at 325 for 24 minutes (may vary)
