Sift together flour, oats, cinnamon, soda and salt and set aside.
Beat together butter and sugars until light and fluffy. Beat in egg and vanilla. Stir in dry ingredients.
Form into balls using a tablespoon of dough for each cookie. Place on ungreased cookie sheets. Bake at 350° for 8 minutes. Place a chocolate kiss on top of each cookie until it cracks around the edges. Bake 2-4 minutes more until golden brown. Watch carefully as you don’t want to melt the kisses, just soften them!
Cool slightly on the baking sheets before transferring to cooling racks.
This recipe will make approximately 4 dozen cookies. Actual amount may vary depending on the size of each cookie.
