Roll dough into 1-inch balls and place on prepared baking sheets about 2 inches apart. Use your thumb to make an indent in the top if each dough ball. Bake for about 10 – 14 minutes. Remove from oven and allow to cool for 5 minutes before carefully transferring them to a cooling rack. Once they are somewhat cool, lightly press a Hershey’s kiss into the center to re-form the well. You don’t want to place them yet, because the warm cookies will just make them melt. Once they have cooled, gently press the kiss into the well.
