- 2 cups shredded zucchini
- 1 cup vegetable oil
- 1 cup white sugar
- 1 cup packed brown sugar
- 3 eggs
- 2 teaspoons vanilla extract
- 2 cups all-purpose flour
- 1 cup whole wheat flour
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 teaspoon ground cinnamon
- 1/2 teaspoon baking powder
- 3 cups chopped plums
- 1 tablespoon white sugar
- 1 teaspoon ground cinnamon
- Preheat oven to 350 degrees F (175 degrees C). Line 2 bread pans with parchment paper or spray with cooking spray.
- Whisk zucchini, oil, 1 cup white sugar, brown sugar, eggs, and vanilla extract together in a bowl until well mixed. Combine all-purpose flour, whole wheat flour, baking soda, salt, 1 teaspoon cinnamon, and baking powder together in a separate bowl. Gradually stir flour mixture into zucchini mixture until batter is just combined; fold in plums. Pour batter into the prepared pans.
- Mix 1 tablespoon white sugar and 1 teaspoon cinnamon together in a small bowl; sprinkle over batter.
- Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 1 hour. Cool in the pans for 10 minutes before removing to cool completely on a wire rack.
