Banana Brownies

Banana Brownie Recipe

These banana brownies are my favourite thing to make with over-ripe bananas. They’re simple to make and absolutely delicious. The recipe is made using crushed bananas, mixed into a rich, moist banana brownie batter.

The brownies are soft and sweet – and the addition of banana makes the texture kind of… spongey? They’re different to non-banana brownies for the texture (and of course, banana flavour) and I love that! They’re moist and last in the fridge for up to 7 days too! I love to eat these served with a scoop of ice cream, or lashings of vanilla custard.

This is a recipe I go to when I have leftover brownies but don’t fancy banana bread… overripe leftover bananas are the perfect excuse to get baking! These brownies also freeze well, and can be easily defrosted whenever you fancy one! They’re super decadent and very chocolatey, despite not having any melted chocolate in them.

Prep Time 10 minutes
Cook Time 30 minutes

  • 220g golden caster sugar
  • 2 large eggs
  • 60g cocoa powder
  • 1/2 tsp salt
  • 1/2 tsp baking powder
  • 1/2 tbsp vanilla extract
  • 90g plain flour
  • 3x ripe bananas


  1. Preheat your oven to 180C
  2. Line your baking tray/dish and line with parchment or baking paper
  3. In a pan (or microwave) melt the butter until liquid (gently heat for 10-second batches in the microwave, or gently heat in a pan and keep your eye on it - mixing throughout
  4. Once the butter is melted, add the sugar into the hot butter and stir until combined
  5. Allow this to stand whilst you mix the below
  6. Peel and crush your bananas in a bowl
  7. Lightly beat the eggs in a large mixing bowl, then add in the cocoa, salt, baking powder, flour and vanilla and mix together using a whisk or fork
  8. Add the hot butter/sugar mixture to the egg/cocoa mixture and stir until smooth
  9. Pour the brownie mixture into the lined baking tray
  10. Smooth the top until the mixture is evenly spread out in the tray
  11. Bake the brownies for 30-35 minutes, until the brownies are 'set' on the edges, but the still moist centre (they'll firm up as they cool - you don't want the middle to be liquid though, it's just likely to be a little softer than the edges when fresh out of the oven)
  12. Remove them from the oven and allow to cool before cutting and serving
  13. The brownies will keep in the fridge for up to 7 days in an airtight container
