water. Stir. Cool.
In large mixing bowl, beat eggs until foamy, then add sugar, 2 tablespoons at a
time, beating until thickened (5 minutes in electric mixer). Blend in chocolate.
Add flour, baking powder, salt and cinnamon; blend. Stir in vanilla and nuts.
Grease cookie sheet. Drop teaspoonfuls of batter onto cookie sheet. Bake until
