When making the thumbprint, make a generous indentation, as it will partially fill in as the cookie bakes.
Difficulty Level: Intermediate
Prep Time: 35 minutes
Chill Time: 1 hour
Bake time: 20 to 25 minutes
Yield: 4 dozen cookies
1 cup butter OR margarine
1/2 cup sugar
1 teaspoon Spice Islands® Pure Vanilla Extract
1/2 cup Karo® Light Corn Syrup
2 eggs, separated
2-1/2 cups all-purpose flour
1/4 teaspoon salt
2-1/2 cups finely chopped walnuts
1 can (21 ounces) cherry pie filling
Beat butter, sugar and vanilla together in a large bowl mixer at medium speed, until smooth. Beat in corn syrup and egg yolks. Stir in flour and salt until blended.
Cover; chill 1 hour, if necessary, until dough is firm.
Preheat oven to 325°F. Lightly beat egg whites in a small bowl. Roll dough into 1-inch balls; dip in egg whites and roll in walnuts. Place 2-inches apart on greased cookie sheets. With thumb make indentation in center of each cookie.
Bake for 20 to 25 minutes or until golden. Remove to wire rack. Cool completely. Fill indentations with cherry pie filling.
Variation: Instead of pie filling, a candied cherry half can be pressed into the center of each cookie before baking.
