Line your baking sheets with parchment paper and set them aside.
In a large bowl, beat together the peanut butter, unsalted butter, light brown sugar, and granulated sugar using an electric hand mixer on medium speed until the mixture turns creamy and smooth (3-4 minutes). If your electric mixer seems slow, you can push it up to medium-high.
Add the egg and vanilla extract and beat until fully incorporated.
Take another bowl and mix together the flour, baking soda, baking powder, and salt and set aside.
Add the dry ingredients to the wet ingredients in two separate and equal additions; mix after each addition until just incorporated.
Cover and chill the dough for 1 hour in the fridge.
Once chilled, scoop around 1 ½ tbsp (about 40 gm) of cookie dough and roll it into dough balls. Roll the balls in another 1/2 cup of granulated sugar and place them in the prepared baking tray about 2 inches apart from one another.
Preheat your oven to 375 degrees F / 190 Degrees C.
Bake in a preheated oven for around 10-11 minutes or until light golden brown. While the cookies bake, unwrap your kisses.
Remove the cookies from the oven and immediately press the kisses in the middle of the cookies.
Let the cookies cool on the baking tray for a few minutes before transferring them to a cooling rack to cool completely.
Serve and enjoy!
