PREPARATION:

1. Preheat oven to 350°F. Spray baking sheets with nonstick cooking spray.
2. Beat cake mix, orange juice, orange peel and vanilla in medium bowl at medium speed of electric mixer 2 minutes or until mixture is crumbly. Increase speed to medium-high and beat 2 minutes or until smooth dough forms. (Dough will be very sticky.)
3. Coat hands with nonstick cooking spray. Shape dough into 1-inch balls. Place balls 2-1/2 inches apart on prepared baking sheets. Press center of each ball with thumb. Fill each thumbprint with 1/4 teaspoon fruit spread. Sprinkle with nuts.
4. Bake 8 to 9 minutes or until cookies are light golden brown and no longer shiny. Do not overbake. Remove to wire racks to cool completely.
