Instructions: Preheat oven to 350 degrees F. Line 2 baking sheets with parchment paper. Combine cake mix, flour, butter, eggs and vanilla in large bowl. Beat at low speed with electric mixer until well blended. Mix in cranberries, nuts and lemon rind.

Divide dough in half. Shape each half into a 12x2-inch log; place logs on prepared baking sheets. (Bake logs separately.)

Bake each log 30 to 35 minutes or until toothpick inserted in center comes out clean. Remove from oven; cool on baking sheets 15 minutes. Using serrated knife, cut logs into 1/2-inch slices. Arrange slices on baking sheets. Bake slices 10 minutes at 350iF. Remove to cooling racks; cool completely.
