Cream the butter and sugar together. Add the milk, eggs, baking soda and baking powder. Gradually mix in the flour so it will easily roll out. Roll about 1/4" thick, cut out with glass dipped in flour to about 2" circles.
For the raisin filling, place the sugar and cornstarch in a saucepan and stir in the water and raisins. Cook over medium heat until thick and bubbly. Cool.
Place 1 t raisin filling on top of each dough circle. Cover each with another dough circle. Press edges together with fork tines dipped in flour.
