Most banana bread is designed to be eaten warm with butter, which makes it soft and a bit fragile. This one is deliberately firmer so a slice can go in a lunchbox and arrive as a slice rather than as crumbs.

The bananas have to be properly gone

Heavily speckled or black. Yellow bananas give you a pale, bland loaf, because the starch hasn’t converted to sugar yet — this is the main reason a banana bread disappoints. If yours aren’t there, bake them in their skins at 180°C/350°F for about 15 minutes until black, then cool before using.

Why it slices instead of crumbling

Slightly more flour and slightly less sugar and fat than a standard recipe. Sugar keeps cake soft and tender, which is lovely on a plate and unhelpful in a bag. If you want the softer version, add another 40g sugar and an extra tablespoon of oil.

The other half of it is cooling. Slice it warm and it tears. Let the loaf cool completely — an hour at least — and the crumb sets firm enough to cut cleanly.

Storage

Three days wrapped at room temperature, or slice it and freeze. Freezing in slices is far more useful than freezing the loaf: you take out exactly what you need at 7am and it is thawed by break. Best quality within about two months, matching general freezer guidance for baked goods.

Banana Bread That Survives a School Bag

A firmer, less sugary banana loaf that slices cleanly and freezes in portions.

Prep15 minutes
Cook55 minutes
Total1 hour 10 minutes
Serves1 loaf (about 10 slices)

Ingredients

  • 3 very ripe bananas (about 300g peeled), mashed
  • 2 large eggs
  • 120ml neutral oil
  • 120g light brown sugar
  • 1 tsp vanilla extract
  • 250g plain or all-purpose flour
  • 1 tsp bicarbonate of soda (baking soda)
  • 1 tsp baking powder
  • 1 tsp ground cinnamon
  • 1/2 tsp fine salt

Instructions

  1. Heat the oven to 180C / 350F / gas 4. Grease and line a 2lb (900g) loaf tin with baking paper.
  2. Mash the bananas in a large bowl until almost smooth.
  3. Whisk in the eggs, oil, sugar and vanilla.
  4. Add the flour, bicarbonate of soda, baking powder, cinnamon and salt on top, then fold just until combined. Stop while a few streaks of flour remain.
  5. Scrape into the tin and level the top.
  6. Bake for 50 to 60 minutes, until risen and a skewer in the centre comes out clean. If the top is browning too fast after 40 minutes, lay a piece of foil over it.
  7. Cool in the tin for 10 minutes, then lift out onto a wire rack and cool completely before slicing - at least an hour.

Notes

  • The bananas must be heavily speckled or black. If not, bake them in their skins at 180C/350F for 15 minutes, then cool.
  • For a softer, cake-like loaf add 40g more sugar and 1 extra tbsp oil.
  • Slice before freezing. Individual slices thaw in a lunchbox by mid-morning.
  • Keeps 3 days wrapped at room temperature, or about 2 months frozen.
