Preheat your oven to 350°F and prepare a bread dish by lining it with parchment paper and greasing lightly with coconut oil.
In a large mixing bowl, combine the eggs, mashed banana, coconut oil, nut butter, and vanilla extract. Whisk until the mixture is creamy and smooth.
Add the almond flour, cinnamon, and baking powder to the wet mixture. Stir until just combined, ensuring the batter is smooth and free of lumps. For an extra twist, fold in chocolate chips or chopped nuts.
Pour the batter evenly into the prepared bread pan, smoothing the surface with a spatula if needed.
Bake in the preheated oven for 40-45 minutes, or until a toothpick inserted in the center comes out clean.
Remove from the oven and let the bread cool completely in the pan before slicing. Enjoy warm or at room temperature!
