Preheat oven to 350℉/175℃ and grease a 9-inch loaf pan.
Over a large mixing bowl, sift 1¾ cups whole white wheat flour, 2 teaspoons baking powder, ½ teaspoon baking soda, and ¼ teaspoon iodized salt and give it a quick whisk to combine.
In a separate large mixing bowl, combine ¼ cup canola oil, ½ cup honey, ¾ teaspoon vanilla extract, and 1 large egg. Add in 1 cup mashed banana and mix well.
Stir dry ingredients into wet ingredients until just combined, being careful not to over-mix.
Bake for 45-55 minutes, or until toothpick inserted in center comes out with just a few moist crumbs or the clean. Alternatively, insert a digital thermometer into the center of the loaf. It will be done baking when it reaches an internal temperature of 200-205°F.
Cool the banana bread for 10 minutes in the loaf pan on a cooling rack. Gently loosen the bread from the sides of the pan by running a butter knife along edges, then remove the bread from the pan. Let finish cooling to room temperature before slicing to keep slices intact.

Notes
Storage: Allow the loaf to cool fully before wrapping well or placing it in an airtight container. Store for 2 days at room temperature or in the refrigerator for up to 5 days and freeze for up to 3 months. Egg-Free: Mix 1 tablespoon ground flaxseed with 3 tablespoons water and let sit for 5 minutes and use in place of the egg.Bananas: Be sure the bananas are super ripe for the most flavor and sweetness. 1 cup of mashed bananas is equivalent to 3 medium bananas. Using Frozen Bananas: Microwave about 2 cups of peeled frozen banana chunks for 1 to 2 minutes and then mash well. Measure out 1 cup of banana puree (should be about 1 cup exactly) and let cool before adding to wet ingredients, so you won't scramble eggs.
