Line a large baking sheet with a silicone baking mat or parchment paper.
In a large mixing bowl, cream butter and powdered sugar using the paddle attachment on high speed until light and fluffy, about 1 minute, scraping the bowl sides as needed.
Add the flour and mix on low speed just until a dough forms.
Using a tablespoon-sized scoop, measure heaping scoops of dough. Press a chocolate kiss into the center of each portion and wrap dough around it completely, rolling into smooth balls.
Place cookie dough balls about 1 inch apart on the prepared baking sheet.
Chill the dough balls in the refrigerator for 15 minutes to prevent spreading during baking.
Preheat the oven to 350°F (177°C) while the dough chills.
Bake cookies for 12 minutes or until they are set but still pale.
Remove cookies from oven and let cool on the baking sheet.
Once cooled, dust the cookies with powdered sugar before serving.
