CREAMY BLENDER CHOCOLATE FROSTING

6 squares (1 oz. each) unsweetened baking chocolate
1 cup evaporated milk
1 teaspoon vanilla
1 1/2 cups sugar
6 tablespoons margarine

Cut chocolate into small pieces. Put all of the ingredients into a blender. Cover.

At low speed, blend until larger pieces are chopped. Stop motor and stir. Blend at high speed until frosting becomes thick and creamy.

This frosting is absolutely scrumptious.
