Preheat the oven to 350 degrees. Line a couple cookie sheets with parchment and set aside.
In the bowl of a stand mixer, combine the softened butter, sugar and brown sugar. Cream until smooth.
Add in the eggs and vanilla, mix well.
Add in the flour, baking soda and salt and mix thoroughly, scraping the sides and mixing well again
Divide the dough between three bowls. Tint one bowl green, another red and keep the remaining bowl white (to be rolled in the sprinkles).
Measure out about a tablespoon or small ice cream scoop worth of dough and roll into a ball.
Green and red can be directly placed on the prepared parchment, about two inches apart.
The untinted dough should be rolled into the sprinkles of your choice - pressing slightly to secure them in place.
Bake in the preheated oven for 8-10 minutes or just until the edges are slightly browned and the center is set.
Immediately top with a Hershey’s Kiss so that it melts slightly and secures it to the cookie.
Allow to cool.
Notes
Tips + Storage
Don't overmix the dough - this can lead to flat, crunchy cookies.
Don't overbake cookies - they will continue to cook and set as they cool on the baking sheet. Once edges are lightly browned they can be removed from the oven.
Add the Hershey's Kiss on top while cookies are still warm to allow it to slightly melt and "glue" itself to the top of the cookie.
Cookies can be stored in an airtight container for 3 - 5 days or frozen up to a year.
