Preheat your oven to 175 degrees Celsius, fan-forced. Grease and line a regular loaf tin with baking paper.
Combine your bananas, eggs, almond butter, melted butter and vanilla in a food processor, Thermomix or high-powered blender, and blend until combined (if using a regular mixing bowl, simply mash the banana and stir well to combine with the other wet ingredients).
Sift in the coconut flour, cinnamon, baking soda, baking powder and salt, and stir to combine.
Pour into your prepared loaf pan, smooth flat and place in the oven to cook for 55-60 minutes, or until a skewer inserted comes out clean.
Remove from the oven, allow to stand for 5 minutes, then turn onto a cooling rack to cool.
Serve warm, toasted or as is. Enjoy!
