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.

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.
