In a large bowl, add in the butter and sugars. Cream together with the electric hand mixer.
Beat in the egg.

Sift the dry ingredients over the wet. Mix with the rubber spatula until combined.
Roll each cookie into a 1 Tbsp. ball and place onto cookie sheet 2 inches apart.
Put an x through each one or use peanuts to make a flower pattern making sure to press in the peanuts (I used peanut's split in half)
