Prepare the Cookie Dough

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat to prevent sticking.
2. Mix Peanut Butter and Sugar: In a large mixing bowl, combine the peanut butter and granulated sugar. Mix well until smooth and creamy.
3. Add the Egg and Vanilla: Crack the egg into the peanut butter mixture and add the vanilla extract. Stir until combined.
4. Incorporate Dry Ingredients: In a separate bowl, whisk together the baking soda and salt. Gradually add the dry ingredients to the peanut butter mixture, stirring until fully combined.
5. Chill the Dough: Roll the dough into 1-inch balls using your hands. Place them on the prepared baking sheet, spacing them about 2 inches apart. Roll each dough ball in granulated sugar before placing it on the baking sheet.

Bake the Cookies

1. Bake the Cookies: Bake the cookies in the preheated oven for 8-10 minutes, or until they are golden around the edges and set in the middle.
2. Add the Hershey’s Kisses: As soon as the cookies come out of the oven, press a Hershey’s Kiss gently into the center of each cookie. The cookie will crack around the edges, which is totally normal.
3. Cool: Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
