Begin by preheating your oven to 350 degrees F.

In a mixing bowl, combine the sugar, peanut butter, and egg until well blended.

Shape the dough into 1-inch balls. If the dough feels too sticky, refrigerate it for about 30 minutes.

Place the dough balls on an ungreased cookie sheet and bake until the edges set, roughly 10 minutes.

Immediately press a Hershey's Kiss into the center of each warm cookie. Allow them to cool on a wire rack.

Once cooled, indulge in the deliciousness!
