Hershey Kiss cookies

1/3 cup softened butter
1/2 cup peanut butter (128 grams--we find it easiest to measure peanut butter by weight right in the bowl)
3/4 cup brown sugar
1 egg
1 tsp vanilla
1 1/3 cup all purpose flour
1 tsp baking soda
1/2 tsp kosher salt
(White sugar for dusting)
Bag of Hershey Kisses, or similar shaped chocolate candy

Pre-heat oven to 375ºF
Cream together the butter, peanut butter and brown sugar. (We do this in a stand mixer.)
Add the egg and vanilla, mix until combined
Combine the flour, baking soda and salt in a separate bowl and add to the other mixture. Combine thoroughly.
Roll the dough into small balls (a rounded teaspoon is a good start), optionally roll around in white sugar and place on a lined baking sheet. We use a SILPAT, but parchment paper works as well.
Bake for 9-10 minutes, the cookies will have puffed up and be golden brown.
Top each cookie with a Hershey Kiss, pressing down lightly so that the candy becomes part of the cookie

Cookie size is variable, but since the dough will puff up in the oven we use a fairly small size (approximately 1 1/2 tsp).
These freeze surprisingly well
