Preheat oven to 350 degrees F. Line baking sheets with parchment paper and set aside.
In a large bowl use a mixer (medium speed) to combine peanut butter, brown sugar, and baking soda until well blended.
Add eggs and vanilla; mix on low speed until just combined.
Using a Tablespoon, generously scoop out dough to make 1 1/2 inch balls. Roll each ball in the sugar and place on baking sheet, 2 inches apart on prepared baking sheets.
Bake until cookies are puffed and a bit cracked, 11-13 minutes.
As soon as they come out of the oven, press the chocolate kiss or a few chocolate chips into the center. To add jam, use the back of a spoon to create a small well in the center of the cookie.
