Preheat the oven to 350 degrees F (180 degrees C).
Grind the Dry Roasted, Unsalted Peanuts (1 1/2 cup) into a fine powder using a food processor.
In a large mixing bowl, combine the ground peanuts, All-Purpose Flour (1 1/2 cup), Powdered Confectioners Sugar (1/2 cup), Granulated Sugar (1/2 cup) and Salt (1 pinch). Mix well.
Pour Peanut Oil (3/4 cup) over the peanut mixture and knead with your fingers until a dough forms.
Take about 1 teaspoon of the dough and form it into a ball by squeezing the dough in your hand first, then gently rolling it in between your palms. If the dough crumbles too easily, add more oil to the dough.
Arrange the cookie dough balls about an inch apart on a cookie sheet.
Lightly beat the Egg (1) and brush it on the top of each cookie.
Bake for about 20 minute or until they turn a nice golden brown.
