Ingredients

• 3 cups all-purpose flour
• 1 teaspoon baking soda
• 1/2 teaspoon baking powder
• 1 teaspoon salt
• 2 cups sugar
• 1 cup vegetable oil
• 3 eggs
• 1 teaspoon vanilla extract
• 1 cup sour cream
• 2 cups shredded zucchini
• 1 cup chopped walnuts

Instructions

1. Preheat oven to 350 degrees F (175 degrees C). Lightly grease two 9x5 inch loaf pans.
2. In a large bowl, sift together flour, baking powder, baking soda and salt. In a large bowl, beat together the sugar and oil. Stir in the eggs one at a time, beating well with each addition, then stir in the vanilla. Blend this mixture into the flour mixture, alternately with the sour cream; stir just to combine. Fold in the zucchini and nuts; mixing just enough to evenly combine. Pour batter into prepared pans.
3. Bake in preheated oven for 80 minutes, or until a toothpick inserted into the center of the loaf comes out clean.
