In a large bowl, combine the first seven ingredient. In another bowl, beat eggs; add zucchini, oil and vanilla. Stir into dry ingredients just until blended. Fold in the cranberries and walnuts.
Pour into two greased and floured 9-in. x 5-in. loaf pans.
Bake at 350° for 50-60 minutes or until a toothpick inserted near the center comes out clean. Cool for 10 minutes before removing from pans to wire racks.
