Preheat oven to 350°F. Grease a loaf pan or line with greased parchment paper for easier cleanup.
Mix dry ingredients in a large bowl until fully combined.
In a separate, smaller bowl, mash banana. Add the rest of your wet ingredients and mix until fully combined.
Make a well in the dry ingredients, add wet ingredients and stir gently until fully combined. Pour batter into loaf pan. Be careful not to overmix; this could make your loaf a little too dense.
Bake for approx. 1 hour to 1 hour 10 minutes, or until fork comes out clean. You may cover with tented tinfoil about 40 minutes into baking if you don’t want the top of the loaf to brown more than it already has. Resist the urge to dig in immediately (if you have enough self-determination!) and allow to fully cool before serving.
