In a large mixing bowl, use a hand or stand mixer to beat the butter, peanut butter, sugar, and brown sugar until light and fluffy
Add the egg and vanilla extract, then beat again until everything is smooth.
In a separate bowl, whisk together the flour, baking soda, baking powder, and salt. Slowly add this mixture to the wet ingredients, stirring until just combined. Don’t overmix
If the dough feels too soft to shape, chill it in the refrigerator for 15–20 minutes.
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
Scoop out small portions of dough (about 1 tablespoon each) and roll them into balls. Roll each ball in sugar to coat the outside
Bake the cookies for 8–10 minutes, just until the tops begin to crack
Once they’re out of the oven, wait 2–3 minutes before pressing a chocolate kiss into the center of each cookie
Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack
