Cinnamon-Sugar Butter Cookies

Okay, these are absolutely not safe for my family but my mom requested the recipe recently and, since they are so wonderfully delicious, I decided to post the recipe here.

3 tablespoons sugar
1 tablespoon cinnamon
2 1/2 cups flour
1/2 teaspoon baking soda
1/4 teaspoon salt
1 cup brown sugar
1/2 cup sugar
2 sticks (1 cup) salted butter, softened (no substitutes!)
2 eggs
2 teaspoons vanilla extract

Preheat oven to 300 F. Combine the first two ingredients in a small bowl and set aside. In a medium bowl, stir together flour, baking soda and salt. Set aside. In a large bowl, blend sugars with an electric mixer on medium speed. Add the butter and mix to form a grainy paste. Scrape sides of bowl, then add eggs and vanilla. Mix at medium speed until light and fluffy. Add the flour mixture and blend at low speed just until combined. Do not overmix. Shape dough into 1-inch balls and roll each ball in cinnamon-sugar topping. Place onto ungreased cookie sheets, 2 inches apart. Bake for 18-20 minutes. Immediately transfer cookies with a spatula to a cool, flat surface.
