Date or Raisin Filled Cookies

These cookies are good but kind of labor intensive, so I've only made them once or twice. You end up with a little (ok kinda big for a cookie) pocket full of raisin jam, like a sweet pirogi or something.

Filling:
1/2 c water
2 c dates or raisins
1/2 c sugar
1 T vanilla

Dough:
2 1/2 c flour
1 t baking soda
1 t baking powder
1/2 t salt
1/2 c butter

1/2 c sour milk

Preheat oven to 350F.
Grind water and dates/raisins. Add sugar and vanilla. Optional: add walnuts. Cook 5-10 minutes until thick as jam. Remove from heat, keep covered. 
Sift together flour, baking soda, baking powder, and salt. Combine butter, sugar, egg, and milk. Alternate adding wet and dry to form soft dough. Roll dough thin. For each cookie, cut two large circles. Spoon jam into center of one circle and cover with second. Seal edges, slit top. Bake 15 minutes.
