Whole wheat honey banana bread with walnut

Homemade banana bread is the best breakfast and dessert.  This time, I tried to use all natural ingredients and the result was impressive! 

Ingredients
*1 1/4 cup organic whole wheat flour
*1/2 cup organic oat
*1/3 cup flaxseed
*1/4 teaspoon salt
*1 teaspoon baking powder
*1/4 teaspoon baking soda
*1/3 teaspoon cinnamon
*2 farm fresh eggs
*3 over ripe banana, mashed
*1/2 cup organic butter, melted
*1/2 cup raw honey
*1/2 teaspoon vanilla
*1 cup chopped organic walnut

Directions
1) Preheat oven to 350 degrees. Butter a 9-by-5-by-3-inch loaf pan, and set aside. Whisk together the flours, oat, flaxseed, salt, baking powder, baking soda and cinnamon in a medium bowl, and set aside.
2) In a large bowl, using a electric mixer to combine eggs, banana, melted butter, honey, and vanilla, and mix until combined. Add the reserved flour mixture, and mix on low speed until well incorporated, about 10 seconds. Stir in walnuts.
3) Pour batter into buttered pan. Bake until golden brown and a cake tester inserted into the center comes out clean, about 50-55 minutes. Let cool slightly in pan on a wire rack. Invert bread to unmold; reinvert, and let cool completely on rack.
