Instructions
Oven 175°C / 350°F · 8x4 inch (20x10cm) loaf pan, parchment lined
- 1
Heat the oven to 175°C / 350°F and line a small loaf pan with parchment — no greasing, since there is no fat in the batter to worry about sticking.
- 2
Mash the bananas to a smooth purée; lumps turn into wet pockets in such a lean batter.
- 3
Whisk in the whole eggs, egg whites and honey until completely smooth and slightly frothy.
- 4
Stir in the oat flour, cinnamon, baking soda and salt. Mix only until combined — 20 seconds is enough.
- 5
Pour into the pan, scatter the chocolate chips over the surface so they stay visible instead of sinking.
- 6
Bake 38-45 minutes. The loaf rises tall, then settles slightly as it cools; that is normal with no fat and this much fruit.
- 7
Cool in the pan 15 minutes, then lift out by the parchment and cool fully on a rack before slicing.
Doneness test
A skewer in the centre comes out clean and the top springs back when pressed lightly.
Cooling
Slice only once completely cool — warm fat-free banana loaf is gummy and tears.
Smart substitutions
Egg whites instead of extra whole eggs
Adds structure and protein with almost no calories.
Texture: Lighter, more cake-like crumb rather than a dense custardy one.
Oat flour instead of all-purpose flour
More fibre and a naturally sweet, toasty flavour.
Texture: Softer and moister; the loaf needs a full cool to firm up.
No butter or oil at all
Removes roughly 400 calories from the batch.
Texture: Slightly less tender and it stales faster — keep it refrigerated and warm slices briefly.
Pro baking tips
- The riper the bananas, the sweeter the loaf; you can skip the honey entirely once they are almost black.
- For a protein version, whisk in 2 tablespoons of unflavoured whey isolate and add 1 extra egg white for moisture.
Make it even lighter
Swap an ingredient for a lower-calorie one, use less of it, or skip it altogether — with an honest note on what it does to the taste.
