Ingredients               
2 eggs
2 table spoon of butter
1 cup powder sugar
1 cup corn starch
1 tsp vanilla extract
1 tsp baking powder
2 1/2 cup flour
coco or nuts
 

Preperation
Mix well butter and sugar add eggs and beat well, add in the rest of the ingredients except for coco.
Mix well with a wooden spoon.Roll a piece of dough into a size of a golf ball (almost). Put 1-2 tsp coco,
on a flat plate. Find a small cap; I used the cap of carton orange juice container. Beer cap would work,
too. Wet it a little. Press it first on coco and then on the ball-shape cookie dough. You may need to,
repeat this with every cookie.If you're feeling lazy or you don't want a mushroom-shape cookie,
just put a hazelnut, almond, or pistachio on your cookies.Bake at preheated 370F for 10-12 minutes or,
until they have tiny cracks on them. Do not bake them until they turn yellow or brown! Or you'll lose,
that melt-in-the-mouth texture. Enjoy

This is the best cookie ever!
