Preheat oven to 175°C. Grease an 8-inch baking pan.
Beat eggs in a medium mixing bowl until thick. Gradually add sugar, beating until thoroughly blended. Stir in flour and melted butter; blend well. Add cranberries and walnuts, mixing gently just until combined. Spread evenly in pan.
Bake for 40 to 45 minutes or until golden brown and a toothpick inserted into the center comes out clean. Cool and cut into bars.
