Stir in 1 cup cold milk slowly until completely blended. Separate dough into two balls. Roll out one ball of dough to fit a 15 x 10 inch pan with some dough extending over the edge of the pan.

In a large bowl combine sliced apples sugar cinnamon and 2 tablespoons flour. Place filling in an even layer over prepared crust. Thinly slice 1/2 cup butter and evenly distribute over the apples. Roll out the remaining dough and place over the apple filling. Seal edges and prick the top all over with a fork.
