Garden Harvest Cake

This is also good for breakfast!

4.5 ounces all-purpose flour (1 cup)
3/4 cup sugar
2 teaspoons ground cinnamon
1 teaspoon baking soda
1/4 teaspoon salt
1/2 cup grated peeled Granny Smith apple (about 1 medium)
1/2 cup grated carrot (about 1 medium)
1/2 cup shredded zucchini
1/4 cup chopped walnuts, toasted
1/4 cup oil (or applesauce for less calories)
1/4 cup nonfat buttermilk
2 large eggs
Cooking spray

1. Preheat oven to 350°.
2. Weigh or lightly spoon flour into a dry measuring cup; level with a knife. Combine flour and the next 4 ingredients (through salt) in a large bowl, stirring with a whisk. Add grated apple, grated carrot, shredded zucchini, and walnuts to flour mixture; toss well. Combine canola oil, buttermilk, and eggs in a small bowl, stirring with a whisk. Add egg mixture to flour mixture, stirring just until combined. Spoon batter into an 8 x 4–inch loaf pan coated with cooking spray. Bake at 350° for 50 minutes or until a wooden pick inserted in the center comes out clean. Cool 10 minutes in pan on a wire rack; remove cake from pan. Cool completely on wire rack before slicing.
