Banana flapjacks make a delicious breakfast or snack throughout the day and this recipe requires just six ingredients.

Lots of flapjacks have sugar or syrup as one of the key ingredients. However, our banana flapjacks only include naturally sweet ingredients. This means they provide a stable release of energy and avoid sharp sugar crashes which you might get from food with lots of refined sugars in. For maximum sweetness and flavour make sure your banana is nice and ripe. 


  • 85g dates, pitted
  • 1 banana, roughly chopped
  • 50g butter, melted
  • ½tsp bicarbonate of soda
  • 225g whole jumbo oats
  • 2tsp ground ginger or cinnamon




  1. Heat the oven to 180C (160C fan, Gas 4). Lightly grease a 18cm (7 in) square cake tin. If you have it, line with a sheet of baking paper that overhangs too as this will make it easier to lift the flapjacks out.
  2. Put the dates into a small bowl and pour over 85ml boiling water. Leave to soak for about 10 minutes.
  3. Once softened, put the dates and water into a food processor, along with the banana, melted butter and bicarbonate of soda. Blitz until smooth.
  4. Combine the oats and ground ginger or cinnamon into a large mixing bowl and add the processed date and banana mixture. Stir to combine. Pour the mixture into the prepared baking tin and level with a spoon or palette knife.
  5. Bake for 20 minutes or until a very light golden brown. Gently mark into 10 portions but do not cut all the way.
  6. Cool in the tin completely, then slice into bars. These flapjacks will keep in an airtight container for three days.

Most of the calories in this recipe are coming from the oats, butter, and dates. You could experiment with reducing the butter amount and replacing it with a beaten egg or some more mashed banana. This will bring the calories down but will also change the final texture. 

When are bananas most flavoursome?

The most brown spots on your banana skin, the riper the fruit and the softer the flesh will be. Bananas are also sweetest when the skin is brown and the flesh is soft. This is a good recipe if you have some bananas that are very soft because you are mashing them up anyway. 

Food Writer Jessica Ransom adds, ‘You can add a tiny pinch of clove to the mixture and it will intensify the banana flavour. I do this whenever I bake banana bread and often get lots of compliments.’
