Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper and set it aside.
In a large mixing bowl, combine the room-temperature butter, creamy peanut butter, light brown sugar, and granulated sugar. Using an electric mixer, beat the mixture on medium speed until light and fluffy, about 2-3 minutes.
Add the egg and vanilla extract to the mixture. Beat until well combined, scraping down the sides of the bowl as necessary.
In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined.
Gently fold in the mini chocolate chips, ensuring they are evenly distributed throughout the dough.
Using a cookie scoop or tablespoon, portion out the dough and roll it into balls. Once rolled, coat each ball in powdered sugar, ensuring they are fully covered.
Place the coated cookie balls onto the prepared baking sheet, spacing them about 2 inches apart. Bake in the preheated oven for 10-12 minutes or until the edges are set but the centers are still soft.
Immediately after removing the cookies from the oven, press a chocolate kiss into the center of each cookie. Allow them to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
