Preheat the oven to 350 degrees. Remove the wrappers from 36 Kisses. (That’s 36-ish. This will all depend on how big you roll the dough balls.)
Beat the butter, sugar, vanilla, and egg in your stand mixer or in a large mixing bowl until well blended.
In a medium bowl, whisk together flour, salt, and baking soda. Add a little of the dry mixture to the butter mixture, then put one of the tablespoons of milk in and mix. Then add more flour mixture and mix, and the last tablespoon of milk and mix. Add the remaining flour mixture, if any. (Alternating the milk and the flour mixture will make a better dough and it won’t dry out.)
Shape the dough into 1-inch balls. Roll the balls in the different sugars and sprinkles and place on an ungreased cookie sheet.
Bake 8-10 minutes or until edges are lightly browned and the cookie is set. Remove from the oven and cool for 2-3 minutes. Then press a Kiss into each cookie.
Remove the cookies from the cookie sheet to a wire rack and allow to cool completely.
