Chocolate Banana Cashew Cake (vegan)

Chocolate Banana Cashew Cake

Recipe for a rich and fudgy chocolate banana cashew cake topped with a nutty chocolate icing. It’s vegan, dairy free and made with nutrient rich whole foods. It’s also quite delicious.

I have a new piece of Froothie equipment to play with. It’s an Optimum HealthyFry – a rapid air fryer that can bake cakes too. Who’d have thought it? I have used it for frying of course, but I couldn’t wait to try baking a cake in it.

With my promise to bring you all things vegan this month of Veganuary, I have created this rich and fudgy chocolate banana cashew cake. Ladies and Gentleman, forget the banoffee, I give you banashew.

Banashew Cake

I knew the cake had to be a chocolate cake for We Should Cocoa, but what sort of chocolate cake? For some reason I’d nut butter on my mind. I suddenly remembered the banana chocolate peanut butter cake I once made and what a good combination those three ingredients were. Then I thought of the cashew brownies that won a place in the Cranks recipe book and suddenly my vegan chocolate banana cashew cake was born. CT, being CT, promptly named it Banashew Cake.

Iced Banashew Cake

Chocolate Banana Cashew Cake

Like most of my cakes, this chocolate banana cashew cake is made with nutrient rich whole foods. This one is even more nutritious than normal, even though it’s iced. It contains healthy fats, wholemeal spelt and cashew nut butter. I’ve used rapadura as the sweetener. This is an unrefined form of sugar that retains many of the cane sugar’s nutrients. It’s particularly high in iron, which as a vegetarian, I’m always slightly concerned about.

But don’t worry if you can’t source rapadura, you can use coconut sugar or muscovado instead.

I’ve used my usual wholemeal spelt flour in this recipe, because it really is the baker’s best friend.

Iced Chocolate Banana Cashew Cake (vegan)

The cake is super easy to make. This is mostly because there’s no creaming required and everything can be added to the pan in which you melt the coconut oil. The icing is made in a similar way, by melting. If you’ve scraped the original pan out well with a spatula, you don’t even need to wash it before using it for the icing. I do so hate washing up.

If you don’t have an air-fryer, you can bake this chocolate banana cashew cake in a conventional oven. You just need to up the temperature to 180℃ (350℉, Gas 4). For a larger cake, just double the quantities. This will make a 20cm (8″) round cake. But you will need to bake it for an additional 10 to 15 minutes.

Vegan Chocolate

Vegan chocolate isn’t the easiest to find. Most dark chocolate is made in the same factories as milk chocolate and can be contaminated by dairy. Seed and Bean not only guarantee their dark chocolate to be vegan, but it’s organic as well. Vivani and Pacari are not so easy to get hold of, but they are also vegan and organic.

Optimum HealthyFry

The cake is a fairly modest one as the tin size that comes with the Optimum HealthyFry* is only 15cm / 6″ in diameter, but the quantities can easily be doubled for a more standard size. It’s quite a rich cake, so although it’s extremely delicious, a little goes a long way.

I have used the Optimum HealthyFry for purposes other than cake – honest! I’ll be writing a review and bringing you more recipes over the next month or so as part of #Jumpstart17. As a Froothie Ambassador, I can offer Tin and Thyme readers free P&P on any Froothie appliance* – add 2483 free ambassador delivery to the comment box when ordering to get free postage and packing.

Author: Choclette


  • 50 g coconut oil
  • 100 g rapadura can use coconut sugar or dark muscovado
  • 1 ripe banana - sliced
  • 2 tbsp cashew nut butter
  • 1 tsp apple cider vinegar
  • ½ tsp vanilla extract
  • 100 g wholemeal spelt flour
  • ¾ tsp baking powder
  • tsp bicarbonate of soda
  • 25 g cocoa powder
  • 75 ml hot water

Chocolate Cashew Icing

  • 10 g coconut oil
  • 1 tbsp cashew nut butter
  • 1 tbsp maple syrup more if you like a sweeter icing
  • ¼ tsp vanilla extract
  • pinch Himalayan pink salt
  • 25 g dark chocolate - roughly chopped make sure it's vegan


  • In a large pan melt the coconut oil over a low heat.
  • Add the cashew nut butter, banana and rapadura and stir until the banana has more or less broken down and the mixture is almost smooth.
  • Remove from the heat. Add the vanilla and cider vinegar and stir.
  • Sift in the dry ingredients and gently stir, adding the water bit by bit as you go along.
  • Line or oil the cake pan (or use a 15cm / 6" silicone mould or tin).
  • Pre-warm the air-fryer as instructed.
  • Scrape the batter into the pan and cover with foil.
  • Set the temperature to 170℃ and bake for 25 minutes. Remove the foil, set the timer for a further 10 minutes and bake until an inserted skewer comes out more or less clean.
    Alternatively bake in the middle of an oven at 180℃ (350℉, Gas 4) following the same procedure as above, but for an extra 10 to 15 minutes.
  • Remove the pan and allow to cool for ten minutes before turning out onto a wire rack to cool completely.

Chocolate Cashew Icing

  • Melt the coconut oil in a pan over very low heat. Add all the other ingredients, except for the chocolate and stir until smooth.
  • Remove from the heat - add the chocolate and stir until combined.
  • Spread over the top of the cake.
  • Scatter with dark chocolate shavings if wished.


The cake is quite rich, so a little goes a long way.
Double the quantities for a 20cm / 8" cake tin and bake for an additional 10 to 15 minutes.

    Love the idea of a banashew cake!! Sounds yummy. I used to have an air fryer and really loved it, but this one seems so versatile since you can bake in it too!

    • Choclette

      20th January 2017 at 6:33 pm

      It’s not what I was expecting when I signed up to an air fryer. It’s great to have such versatility!

    A healthy chocolate cake…how awesome is that! I love that frosting.

      It’s got to be done Angie 😉

    Ooh that airfryer sounds amazing! Never would have imagine you can bake in one. This looks delicious

    • Choclette

      20th January 2017 at 5:47 pm

      Thanks Lucy. No, cake making wasn’t what I had in mind when I heard about the air fryer 😉

    I was craving a chocolate cake the other day and used coconut sugar and coconut flour.

    • Choclette

      20th January 2017 at 5:46 pm

      How did it work out Heidi. Coconut sugar is fab, but I find coconut flour on it’s own makes for a very heavy cake.

    I’m so impressed with this cake and that you made it in the air fryer. I’m super excited to try this myself and I love the banana cashew combination.

    • Choclette

      20th January 2017 at 5:44 pm

      Thanks Janice. Making cakes in it wasn’t what I originally had in mind, but it worked well. Have you tried yours out yet?

      • Janice

        21st January 2017 at 8:39 pm

        Yes, I’ve made a couple of things, it’s really easy to use.

          23rd January 2017 at 11:23 am

          Yes it is and I’m enjoying not having to turn the oven for just a few chips 😉

    Oh my, Choclette… this may be my favourite of your vegan recipes! I am definitely making this! I love how the banana is cooked down with the fats and sugar, I bet it smells divine!
    Glad you are having fun with your new toy!!

    • Choclette

      Thanks Poppy. Cake making in the air fryer wasn’t quite what I had in mind when I first heard of it, but it works well.

    Cooking a cake in an air-fryer sounds very unusual. But your ‘banashew’ sounds amazing! Fantastic ingredients, although I’ve never heard of rapadura. Where do you find it? x

    • Choclette

      23rd January 2017 at 11:16 am

      Thanks Kate. The beauty about making a cake in the air-fryer is not having to turn the oven on for only a small item. I used to buy rapadura from our local organic shop, but that sadly closed down. I now stock up whenever I happen to be passing a good health food shop.

      I wasn’t expecting the Healthy Fry to come with a cake tin. It just had to be tried.

      23rd January 2017 at 11:12 am

      Thanks Jac. It’s not quite what I thought I’d be doing with the air fryer, but it’s great that it’s so versatile. Looking forward to experimenting some more.

      Thanks Sarah. It’s a fab combination and makes for a gorgeous cake 🙂

    I had no idea you could make cakes in an airfryer – I thought they were mostly used for making chips!

      24th January 2017 at 5:41 pm

      Chips? Nothing so mundane Cathy 😉

  16. Laura @ KneadWhine

    Oh Choclette – your cakes always look so delicious… and tempting! Cashew icing means healthy, right?

    • Choclette

      27th January 2017 at 11:37 am

      Aw thanks Laura. And yes, healthy icing it is – of course 😉

    Oh wow! This looks totally delicious and is right up my street. I think I might have to try it with my wholegrain gluten free flour blend…I think it would work a treat!

    • Choclette

      27th January 2017 at 1:56 pm

      Oh yes, I can see it working really well with your flour Vicki. Let me know how you get on.
