2 cups raisins
1 can (14 oz.) sweetened condensed milk
1 tablespoon grated lemon peel
1 tablespoon lemon juice
1 cup margarine or butter, softened
1-1/3 cups firmly packed brown sugar
1-1/2 teaspoons vanilla
2-1/2 cups Quaker Oats
1 cup flour
1-1/2 cups chopped walnuts
1/2 teaspoon baking soda
1/4 teaspoon salt (optional)

Heat oven to 375 F. Grease a 13 x 9 inch baking pan. In medium saucepan, combine the first four ingredients. Cook over medium heat, stirring constantly, just until mixture begins to bubble. Remove from heat, cool slightly, set aside. Beat margarine, sugar and vanilla until fluffy. Add remaining ingredients. Blend until crumbly and evenly mixed. Reserve 2 cups. Press remaining mixture onto bottom of prepared pan. Spread raisin mixture to within 1/2 inch of edge. Sprinkle with remaining oat mixture. Pat lightly. Bake 25-30 minutes or until golden brown. Cool completely. Cut into 1 x 2 inch bars. Makes 4 dozen.
