+ Well Nourished ⎮ Three Ingredient Brownie

Three Ingredient Brownie

Three ingredient chocolate brownie

There’s nothing better than a simple recipe that ticks both the taste and nutrition boxes. Plus, it seriously doesn’t get any quicker or easier than this.

Health benefits
These are a great healthy snack for active kids because the nut butter provides them with protein, healthy fats and complex carbohydrate and the bananas, as well as being an amazing source of complex carbohydrate, are rich in minerals which are often depleted during heavy activity. The cacao makes them chocolatey good and is also a great source of antioxidants.

6 medium sized, very ripe bananas (2 cups approx.)*
250g (1 cup) nut butter (any kind you like, such as peanut butter, almond butter, hazelnut butter etc;)
60g (½ cup) cacao powder (you can use less if you prefer a less intense chocolate flavour)


  1. Preheat your oven to 180℃ and line a small brownie tin with baking paper.
  2. Mix all of the ingredients together in a powerful blender or food processor (Thermomix, 15sec, speed 5).
  3. Pour into the lined tin and bake for 25-30 minutes or until firm to touch.
  4. Allow to cool and slice into squares. These can be frozen for up to a month.

*The more ripe the bananas, the sweeter these will be. As there are no other sweeteners ripe bananas are a must.

    Love them Georgia! And not just for the kids…lol. I’m going to take some on my next sea kayak trip. The other group members will be very jealous…

  • Natalie

    I was very excited to find bags of ripe bananas for 99c at my local greengrocer today which were perfect for this recipe. It couldn’t be easier! I used hazelnut butter and got the thumbs up from the whole family.

    • I love chocolate and hazelnut together – good choice and great pick up with the bananas G x

  • Shannon

    Amazing- Made twice already and my whole clan loves them, even the fussiest little one. Thank you. I just love your recipes, both your ebooks are permanently on the counter top. Love your work! Shannon

    • Thanks Shannon – appreciate your support and thrilled you are enjoying G x

  • sinead

    can you freeze these?

  • Meredith Warner

    This is delicious, just what we needed on the dreary day. I only had 4 bananas so made the rest up with sweet potato purée and it worked brilliantly. Thanks for all the amazing work you do.

    • Yay, glad you enjoyed them. You’re very welcome Meredith G x

  • Amy Holiday

    Hi, I made these brownies today, they were exceptional! I used ripe bananas, hazelnut butter and the full 60g of cacao powder. My blender broke this week but I was able to mix the ingredients with a potato masher with great results! They are great hot or cold. Thank you for the recipie!

    • Thrilled you liked them Amy – I particularly love them with hazelnut butter too and great to know they were a success made without a blender too. Thanks for the pic G x

    • Demi Noakes

      where do you get your hazelnut butter from?

      • My supermarket sometimes has it, also seen in health food stores x

  • Sandra

    Hello my son is allergic to peanuts and nuts, what can I use instead of nut buttet? Thank you.

  • Katherine Prior

    These look delicious, I’m going to make some today. Should I avoid giving my 1 yr old cacao for another year or so?

    • Hi Katherine. Everyone is different in their response to cacao. You could sub with carob though. G x

      • Katherine Prior

        Thanks Georgia, I’ll see how he goes

  • Natasha

    Hello, just wandering is there any substitute you could use for the bananas?

    • You could try stewed apple, but I’ve only tested the bananas G x

  • Shelly

    Hi there, as my son has type 1 diabetes I need to know the sugar and carbohydrates count in everything. Do your receipes have this information.

    • No sorry Shelly they don’t I’m afraid G x

    • Helen Barnett Hodges

      Hi Shelly, you could enter the ingredients into an app like CalorieKing or MyFitnessPal (or equivalent) and that should give you an idea for the whole recipe. To get an exchange you can just work out how much you’re going to have to divide the slice by (ie if the slice has 150g of carb in total then to get a 15g carb exchange you’ll just need to cut the slide into 10 slices. However, these days, with more of the dose adjustment for normal eating models being taught for T1DM, the 15g exchange may not necessarily be needed – depends what model/treatment plan you’re working with – everyone is different. Hope that helps.
      Unfortunately you may also find that the riper the banana the higher the carb content – but this may not be reflected in the calorie/carb apps (they’re all just an average anyway) – so with a recipe like this you may find that your sons glucose response is higher than expected, or higher more quickly than expected because of the ripeness of the bananas.

  • Victoria Hunt

    Successfully halved this recipe and used frozen bananas. Added a heaped Tblspn Superfoods Choc chunk with cocoa. Topped with a sprinkling of dark choc drops. Cooked a bit longer in a 20x20cm tray. Delicious warm and even better straight from the fridge. I’d better save some for the kids! Thanks Georgia.

  • Sounds great Victoria – thanks for sharing your awesome variation G x

Kind words…

“I downloaded your ebooks after hearing you speak at the Health and Wellness Summit in Melbourne. Love them, life changing… Don’t stop! Thank you for getting the whole food message out there, I certainly heard it.” Melanie

“I love your ebooks, I have all three of them now and they are now my only go to receipe books. They are simple, wholesome and taste great. THANK YOU!!! I have spent alot of money on courses about healthy eating and recipe books but your books have covered it all and my little man enjoys the snacks etc. Wish I would have found you earlier “. Brooke

“I just want to say a huge thank you for your amazing website and information. I’ve never liked cooking and never got excited by my ‘healthy’ cooking. My husband is even worse and if he could, he would just eat beacon and eggs every morning and steak every night. He hardly ate any veggies. Since I found your website I have gone through almost every recipe. My husband is loving every meal as well – even meat free Monday, and he’s taking left-overs to work for lunch (honestly, who thought that could be so hard?!)” Rose

“You have truly helped me and my family to lead a healthier lifestyle. I’ve been referring to your page every few days, very inspiring, so thank you!” Emily

“Thank you very much for your awesome website & facebook page posts, you have motivated & inspired me heaps!” Fiona

“Just discovered your site 3 weeks ago, its been a great help with kids lunches for back to school, thanks so much!” Ange

“What a fantastic blog filled with so many great recipes and information!” Carla

“I just wanted to let you know that you have absolutely inspired me to a better way of eating, I’ve been making my shopping lists based on recipes you’ve shared and am educating my kids with the reasons behind different foods and why they are good etc! This page has become my little bible hehe! Thank you so much for all the detail you give. It’s absolutely wonderful!” Sky
