Take our Amish Friendship Bread peanut butter cookie recipe and drop a Hershey Kiss in the center to make a peanut butter blossom cookie.
Preheat oven to 350° F (176° C).
Mix starter, peanut butter, butter, and brown sugar. Add eggs and vanilla extract, and beat well.
Add flour mixture to starter mixture, adding additional flour if needed.
Roll dough into small balls. Roll balls in sugar, then gently flatten with the bottom of a mason jar.
Press one Hershey's chocolate Kiss in the center.
Bake for 10 minutes or until cookies are light brown and set.
