Ingredients: 

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. Use a parchment paper. 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).
