- 1 tablespoon white sugar (optional)
- 2 teaspoons ground cinnamon (optional)
- 2 cups whole wheat flour
- 1 1/2 cups quick cooking oats
- 1 cup all-purpose flour
- 1 tablespoon baking soda
- 1 1/2 teaspoons ground cinnamon
- 1/2 teaspoon salt
- 2 cups dark brown sugar, packed
- 3/4 cup butter
- 1 (16 ounce) container sour cream
- 6 very ripe bananas, mashed
- 3 eggs
- 2 1/2 teaspoons vanilla extract
- 2 cups chopped dates
- 1 cup chopped walnuts
- 1/2 cup toasted flake coconut (optional)
- 1/4 cup dark brown sugar, divided
- 2 tablespoons chopped dates, divided
- 2 tablespoons chopped walnuts, divided
- 2 tablespoons toasted flake coconut, divided (optional)
- 1 tablespoon butter, melted (optional)
- Preheat oven to 300 degrees F (150 degrees C). Grease 4 loaf pans, 7×3-inch size. Combine 1 tablespoon white sugar with 2 teaspoons cinnamon in a small bowl. Dust the insides of the greased loaf pans with the cinnamon sugar.
- Stir whole wheat flour, oats, all-purpose flour, baking soda, 1 1/2 teaspoon cinnamon, and salt in a bowl. Beat 2 cups brown sugar with 3/4 cup butter in a separate mixing bowl until creamy. Beat in sour cream, bananas, eggs, and vanilla extract until smooth. Stir the dry ingredients into the banana mixture and fold in 2 cups dates, 1 cup walnuts, and 1/2 cup toasted coconut.
- Spoon the batter into the prepared loaf pans. Sprinkle tops of each loaf with about 1 tablespoon of dark brown sugar and 1 1/2 teaspoons each of dates, walnuts, and coconut. Brush each loaf with melted butter for a shiny glaze.
- Bake loaves in the preheated oven until browned and a toothpick inserted into the center of a loaf comes out clean, about 1 hour.
