Preheat the Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat.

Make the Dough: In a large bowl, cream together the softened butter and sugar until light and fluffy. Beat in the egg and vanilla extract until well combined. In another bowl, whisk together the flour, cocoa powder, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until combined.

Shape the Cookies: Roll the dough into 1-inch balls, then roll each ball in powdered sugar to coat. Place the dough balls onto the prepared baking sheet, spacing them about 2 inches apart.

Bake: Bake for 8-10 minutes, or until the edges of the cookies are firm but the centers are still soft.

Add the Hershey’s Kisses: Remove the cookies from the oven and immediately press a Hershey’s Kiss into the center of each cookie while they’re still warm. Let the cookies cool on the baking sheet for a few minutes, then transfer them to a wire rack to cool completely.

Serve and Enjoy: Once cooled, enjoy these soft, chocolaty cookies with a Hershey’s Kiss surprise in the center! 🍪🥛
