Banana Brownies

three banana brownies on top of each other

Do you always forget about your bananas until a week later and they are brown and weird and you are thinking why did I buy bananas anyway and you don’t really like banana bread? Yeah me too. So I came up with this banana brownie for all of us forgetful fruit buyers. Thank me later.

P.S. This is a completely sugar-free brownie recipe. I don’t even use any natural sweeteners, just the power of fruit. Booyah!

How did you make this a sugar free brownie recipe?

To make these sugar free I used only very ripe bananas. I mean super-ripe, almost completely brown. If you use yellow bananas the brownies will not be sweet.

I did initially make these with a natural sweetener but I tested the recipe a few times just using bananas and omitting the sweetener and it ended up SO good! The balance of sweetness is perfect!

I did use dark chocolate but you can also use normal milk chocolate if you find dark a bit too bitter.

If you have a super-duper sweet tooth you can also add 100 grams of natural sweetener. Add this at the same time as the eggs and beat them together lightly before adding the mashed banana.

If you do decide to use an extra sweetener I suggest xylitol or a mix that measures 1:1 like sugar. If you are confused by any of this make sure to grab my sugar-free starter pack below! The pack contains a full guide on natural sugar-free substitutes along with a cheat sheet, mini workbook and lots of advice!

Do you have tips for baking banana brownies?

  • Don’t over mix your brownie batter, especially the eggs. If you do there will be lots of air bubbles in the batter which will expand when baked – causing the tops of your brownies to crack. I do this a lot when I’m not paying attention and they still taste great though!
  • Use good quality chocolate! Especially as these brownies have no sugar make sure to use your favourite plain chocolate (Dark is my favourite!) and a good quality cocoa powder if possible.
  • Properly grease the baking pan or line with parchment paper. If you don’t your brownies will stick to the tin and this always ends in disaster when you are trying to serve them!

Directions

  • Preheat oven to 350F / 180 / 160 fan and grease a 29cm rectangular baking dish.

  • In a large mixing bowl combine flour, cocoa powder, baking powder, salt and set aside.
  • In a separate large bowl add eggs and beat well. Then add the mashed bananas, melted butter and vanilla and mix until well combined. Make sure the eggs are broken up and evenly distributed throughout the batter but take care to not overmix after this stage.
  • Add the dry ingredients into the wet banana mixture and stir until just combined. Add the chocolate and mix one more time.
