Preheat the oven to 350° F. Line 2 baking sheets with parchment paper and set aside.
In a large bowl using an electric mixer, cream the peanut butter, sugar, and egg together until smooth.
Scoop 1 tablespoon of dough and use your hands to roll it into a ball. Roll the cookie in the extra granulated sugar (optional) and then place it on the cookie sheet, leaving a few inches in between each cookie.
Bake 1 tray of cookies at a time for 10 minutes, or until set. Remove from the oven and immediately place a hershey kiss in the center, pressing it down so the cookie spreads a bit. Allow the cookies to cool on the cookie sheet.
Notes
Nut Butter - feel free to use almond butter or cashew butter if you prefer!
Adding a hershey kiss - if you’re making peanut butter blossoms, make sure to press the hershey kiss on the cookie immediately after baking. Press gently (but firmly!) on top of each cookie to make sure it sticks and the cookie slightly spreads out.
Use peanut butter cups - if you don’t have any kisses on hand, press mini peanut butter cups on top of each cookie! You can also use any flavor of Hershey's kisses!
