1/4 c. plus 3 tbsp. butter
1/4 c. plus 3 tbsp. sugar
1 egg, beaten
3/4 c. plus 2 tbsp. flour
1 can condensed milk

Cream together butter and sugar; add egg and flour and mix well. Drop by scant teaspoonfuls onto cookie sheet. Pat with a floured finger into very thin little circles (quarter to half dollar size). Bake at 325 degrees for 10-12 minutes, until just starting to brown around edges.

Sandwich two cookies together with cooked condensed milk. To cook condensed milk, place entire, unopened can in a large saucepan, cover with water. Bring to boil and simmer about 2 hours. This turns it into caramel.
