Preheat the oven to 350 degrees. Line baking sheets with Silpats or parchment paper.

In the bowl of a stand mixer, beat the butter on medium speed for 2 minutes. Add the brown sugar and sugar and beat until light and fluffy.

Add in the egg, peanut butter and vanilla and mix until combined.

Whisk together the flour and baking soda in a small bowl. Slowly pour into the wet ingredients, mixing until a soft dough forms.

Place the ⅓ cup of sugar in a bowl for rolling.

Roll tablespoon sized balls of dough with your hands, then toss in the sugar. Place on the prepared baking sheet.

Bake for 8-10 minutes or until lightly golden. Remove from the oven and allow to rest for 2 minutes before placing the candy kiss in the center.

Allow to cool on the cookie sheet for 5 minutes more before transferring to a wire rack to cool completely.
