Prep: 15 mins
Cook: 1 hr
Total: 1 hr 15 mins



  • 1 ¾ cup pureed banana see notes
  • 3 eggs
  • ¼ cup honey
  • ½ cup light brown sugar can sub coconut
  • ¼ cup melted coconut oil measured when melted
  • 2 teaspoons vanilla


  • 2 ½ cups oat flour
  • 2 teaspoons baking powder
  • 1 1/2-2 teaspoons cinnamon see notes
  • ½ teaspoon salt

Cinnamon Swirl


  • Preheat the oven to 350 degrees Fahrenheit.
  • Line a standard loaf pan (9x5 or 8 1/2 x 4 1/2) with parchment paper and set aside.
  • If you're doing the cinnamon swirl, whisk together the cinnamon and sugar in a small bowl and set aside.
  • Add your ripe bananas to a blender and puree. Measure out 1 3/4 cup worth and add to a large mixing bowl.
  • Add in all remaining wet ingredients and whisk together until smooth.
  • Add in the dry ingredients, making sure to spoon and level the flour, until smooth.
  • Add half of the batter to your prepared loaf pan, add in the cinnamon sugar, then top with the remaining batter. Top with crushed walnuts if desired.
  • Bake for 55-65 minutes or until a toothpick comes out clean. About 62 minutes is usually perfect in my oven, but all ovens are different so keep an eye on it.
  • Remove from the oven and let cool in the pan for about 15 minutes, then lift out the bread and let cool for at least 1 hour on a wire rack before slicing.
  • Enjoy as is or top with honey and nut butter or regular butter!


If you are not going to add the cinnamon swirl, I suggest using 2 teaspoons of cinnamon in the batter for the best flavor. Otherwise, 1 1/2 is perfect.
To prevent any coconut flavor from lingering through, I suggest using refined coconut oil. You can also sub for butter.
