Preheat oven to 350°F and grease a 9" or 9.5" bundt pan with coconut oil.
Blend the bananas, eggs, honey, olive oil, vanilla extract, cinnamon, and nutmeg in a bowl until smooth.
Add the dry ingredients (almond flour, baking powder, baking soda, potato starch, and salt) and mix until just combined.
If using, fold in your chopped walnuts.
If no chocolate chips are being used: pour all your batter into your greased bundt pan and spread to ensure an even distribution.If chocolate chips will be added: pour ⅓ of your batter into a greased bundt pan. To the remaining ⅔ fold in your chocolate chips and pour the batter into the pan and spread to evenly distribute it. Bake your banana bundt bread at 350°F for 35-40 min until a toothpick inserted comes out clean.
Once done, remove your banana bread from the oven and allow it to cool in the bundt pan for 5-8 minutes before attempting to turn out onto a cooling rack. Cool for at least 10 minutes before cutting.
Store leftovers in a cool, dry place in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to one week. To freeze, allow the banana bread to cool to room temperature before slicing into 10 portions and wrapping in cling wrap or storing in ziplock bags (with the air removed) for up to four months.
