Soldier Fudge

This recipe was very popular during the Second World War when people wanted to ship goodie to their soldiers overseas. It travels well, lasts a long time and contains no sugar as sugar was rationed during the war.

1 (14 ounce) can sweetened condensed milk
1 (12 ounce) bag semisweet chocolate chips
1 (1 ounce) square unsweetened baking chocolate
1 ½ cups chopped nuts (optional)
1 teaspoon vanilla

Butter a 8-inch square pan.

Heat milk, chocolate chips and baking chocolate over low heat stirring constantly until chocolate is melted and mixture is smooth, remove from heat. Add the vanilla extract and nuts, if using. Spread into pan and chill until firm. Cut into squares.
