Step 1

Preheat the oven to 325°F. Line a large baking sheet with parchment paper and set aside. If desired, unwrap all the Hershey's Kisses from their foil wrappers and place them in a bowl for later (this makes it easier).

Step 2

In a large mixing bowl, add the peanut butter, granulated sugar, and egg. Use a large spoon or electric hand mixer on low speed to mix the ingredients together until a thick dough forms. This does not take very long!

Step 3

Use a small cookie scoop to scoop out evenly-sized balls of dough. Roll each ball of dough between your hands to make it smooth and round.

Step 4

If desired, roll the dough balls in extra granulated sugar to give them sparkly sugar-coated edges. This makes them prettier and even more delicious.

Step 5

Place the dough balls on the prepared baking sheet about 2 inches apart to allow for spreading as they bake.

Step 6

Bake the cookies for 12-15 minutes, or until they have spread slightly and look "puffy" in the middle. The edges should look firm, but not brown. It is better to under-bake them slightly because they will continue to set up as they cool.

Step 7

Remove the cookies from the oven and while they are still warm, gently press a chocolate Hershey Kiss into the center of each cookie. Allow the cookies to cool on the baking sheet for 5-10 minutes to firm up before removing them. Enjoy!
