Sometimes I like to do half of the pan of each, the contrast is very pretty. Sprinkle streusel over pan. Bake 400F for 20 min. Cut in squares and serve. Roll into balls.
Dip balls first into eggwhite, then in chopped almonds, place on baking sheet.
Using knuckle, make indentation in the top of each. Bake 15 min. Bake at 325F 10 min. When done, immediately dust tops of the cookies with powdered sugar. Dough will be dry, and hard to handle.
