Preheat oven to 350°F (177ºC) and prepare parchment-lined 9x5-inch loaf pan.
In a large mixing bowl, whisk together eggs, avocado oil, honey, vanilla and brown sugar until smooth. Next, stir in mashed banana until well combined.
Add flour, baking powder, cinnamon and salt and continue to mix until the flour has been fully integrated. The batter will still be a little lumpy from the banana, but you want the dry ingredients to be mixed in well. Fold in chocolate chips reserving a small handful for the top.
Pour batter into prepared loaf pan, spreading it out evenly with the back of a wooden spoon or spatula if needed. Sprinkle remaining chocolate chips across the top.
Bake for 50-55 minutes until golden and a tester comes out clean. You’ll know your loaf is done if it springs back to the touch. Transfer to wire cooling rack and let cool in pan for 10 minutes before removing. Gently lift loaf from pan using parchment edges then let cool on wire cooling rack for another 20 minutes – this will allow the chocolate chips to firm up. Slice and serve.
