Peanut Cookies

I Need munching! Need snack! but somehow I'm not interested with the cookies in Fl LOL. Back in my home town, there are lots of cookies in different shapes, tastes, from traditional to modern style LOL. I miss them especially in certain events such as after Ramadan, Eid Mubarak. Now I wanna try the sweet one. Well I'm not a sweet kind lover but since I have peanuts and did fry and even ground them, *actually i was about making the peanut sauce for my salad* so I wanna try using some of them for my cookies.

Preparation :
1.5 cups of all purpose flour
half cup of ground peanut (peeled and saute before you grind)
half cup of sugar or more if you like very sweet
half cup of vegetable oil
1 tsp of vanila extract
1 tsp of cinnamon *optional
1 egg yolk for brushing the top of cookies after you shape them

How to make :
Mix all the ingredients and shape the dough *I used my hands and just round shape* brush the top with egg yolk that you have beaten. You can add cheddar cheese on top for decoration or half peanut. Heat the oven 350 F. Bake for about 35-40min.
