Norwegian waffle cookie made with a special decorative two-sided iron griddle. They are popular among Norwegian immigrant descendants in New England and the American Midwest. It was a Christmas tradition when I was growing up.
1/2 cup sugar
1 teaspoon vanilla
1/2 cup butter, melted and cooled
1/2 cup flour
Beat together eggs, sugar and vanilla. Mix in butter. Beat in flour until smooth. (Add more melted butter if krumkakes turn out too thick, or more flour if too thin).
