Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.

Unwrap all the Hershey Kisses and set them aside.

In a large mixing bowl, combine granulated sugar and softened butter, beat until light and creamy. Add egg and vanilla extract, mix until incorporated.

In a separate bowl, whisk together flour and baking soda. Gradually add to the creamed mixture until a soft dough forms.

Roll dough into 1-inch balls and coat in sanding sugar. Place on prepared sheet, spaced 2 inches apart.

Bake for 7 minutes until edges are set and lightly golden.

Press a Hershey Kiss into the center of each cookie immediately after baking.

Cool on the baking sheet for 5-10 minutes, then transfer to a wire rack to cool completely.
