Preheat oven to 375 degrees F. Line a large baking sheet with parchment paper.

Unwrap Hershey’s Kisses and set aside so they are ready to use immediately after baking.

In a large mixing bowl, beat together the sugar and softened salted butter until light and fluffy.

Add the egg and vanilla extract to the butter mixture and beat until well combined.

In a separate bowl, whisk together the flour and baking soda.

Gradually pour the dry ingredients into the creamed mixture, beating until a soft cookie dough forms.

Shape the dough into 1-inch balls. Roll each ball in bright colored sanding sugar until fully coated.

Place dough balls on the prepared baking sheet, spaced 2 inches apart.

Bake for 7 minutes or until the edges are just set (do not overbake).

Remove from the oven and immediately press one unwrapped Hershey’s Kiss into the center of each warm cookie.

Transfer to a wire rack and let cool completely so the chocolate sets before serving.
