Krowki (little Cows)

Cook the milk, sugar and condensed milk over very low heat for 1 hour. Remove from heat. Add the butter and powdered milk and mix well. Lay out on a cooking sheet at a thickess of 1/2 inch. Cut into squares, let cool and harden and roll into papers, if you want. Note: Krowki is similar to a soft praline, use directions for pralines to get to the right cooking stage.
