Preheat your oven to 350°F (175°C). Grease a 9x5-inch loaf pan or line with parchment paper.
In a large bowl, whisk together mashed bananas, eggs, almond butter, honey, melted coconut oil, and vanilla until smooth.
In another bowl, mix flour, baking soda, salt, and cinnamon.
Add dry ingredients to wet, stirring gently until just combined. Fold in nuts or chocolate chips if using.
Pour batter into the prepared loaf pan. Smooth the top.
Bake for 45–55 minutes, or until a toothpick inserted in the center comes out clean.
Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
