Preparation / Directions:
Preheat oven to 350 degrees. Grease cookie sheets well.
COOKIES: 1. Melt margarine in large saucepan. Add remaining cookie ingredients and mix thoroughly. 2. Drop by scant teaspoonfuls onto prepared cookie sheets. Bake for 10-12 minutes or until golden brown. Cool 2 minutes, then remove carefully from cookie sheets to wire rack. 3. Just before serving, put 2 cookies together, sandwich style, with filling.
FILLING: Combine 1 tablespoon flour and 1 tablespoon sugar in saucepan. Gradually add 2/3 cup milk and 2 egg yolks (or 1 whole egg). Mix well. Cook over low heat, stirring constantly, until mixture boils and is thick. Cool. Cream margarine then add 1/4 cup sugar, creaming well. Gradually add egg mixture, beating well after each addition.
