Step 1

Preheat the oven to 350° F. Line 2 large baking sheets with parchment paper or silicone baking liners and set aside.

Step 2

In a medium-sized mixing bowl, whisk together the flour, baking soda, and salt. Set aside.

Step 3

In a separate, large mixing bowl, cream together the butter and sugar until light and fluffy. Add the egg and vanilla extract, beating until combined.

Step 4

With the mixer on low, gradually add the flour mixture and beat until just combined.

Step 5

Continue mixing on a low speed as you stream in the milk. Add just enough to soften the dough.

Step 6

Use a small cookie scoop to portion the dough and then use your hands to roll it into balls. Roll each ball in the colored sugar and place 2-inches apart on the lined baking sheet.

Step 7

Bake for 8-10 minutes or until they’re puffed and the edges are just set, but not browned.

Step 8

Allow the cookies to cool for 2 minutes then press a Hershey’s kiss into the center of each cookie.

Step 9

Allow them to cool for 5 additional minutes before transferring to a wire rack and allowing them to cool completely.
