Cream sugar, butter, egg and vanilla.
Add peanut butter and milk, mix well.
Add in dry ingredients.
Spoon out by spoonfuls (or roll into balls and coat with granulated sugar) and place on an ungreased cookie sheet.
Bake at 375°F for 10-12 minutes.
Remove from oven and top each cookie with a kiss while still hot.
Have kisses unwrapped before removing cookies from oven
If you like crunchy cookies replace butter with shortening, but otherwise the butter makes them nice and chewy.
