It was my lovely Mum’s birthday yesterday and I thought I’d make her a cake. I’m not sure she really wanted a cake, but I think anything handmade is lovely to receive and it gave me an opportunity to blog about it too! She doesn’t eat chocolate so I thought I’d come up with a summery, fruity flavour instead. Two bananas were slowly gathering a mass following of fruit flies in the fruit bowl, so they had to feature, and I’ve been wanting to use some passionfruit for a while… so we ended up with a banana and passionfruit combo! It turned out to be a delicious combination, and one that I am going to be repeating. Nice when experiments work out.
Banana and Passionfruit Birthday Cake (dairy-free, egg-free, nut-free, sesame-free, vegetarian and vegan)
makes 1 cake (mine is a rather tall 8 inch cake, but would make a rather more conventional 9 inch layer cake)
- 400g plain flour
- 1 tsp bicarbonate of soda
- 2 tsp baking powder
- 1/2 tsp salt
- 2 over-ripe bananas
- 175g caster sugar
- 175ml sunflower oil
- 250ml soya milk (I used Alpro banana flavour)
- 1 tsp vinegar
- Preheat the oven to 180 degrees Centigrade/Gas Mark 4
- Grease and line the cake tins
- Add the vinegar to the soya milk and set aside to curdle
- Sift together the flour, bicarb, baking powder and salt. Stir in the sugar.
- In a blender, whizz up the bananas, sunflower oil and soya milk mixture.
- Pour the wet ingredients into the dry and gently mix until no raw flour remains
- Pour into the tins and bake for 30-35 minutes for normal height cake tins, 45-50 minutes for one deep tin, or until a knife comes out clean.
- Cool completely in the tin, then transfer to a wire rack.
- Meanwhile, make the buttercream…
Velvety White Buttercream (dairy-free, egg-free, nut-free, sesame-free, gluten-free, soya-free, vegetarian and vegan)
enough to ice middle and top of the cake
- 1/4 cup vegetable fat (such as Trex)
- 3/4 cup dairy-free spread (such as Pure)
- 3 cups icing sugar, sifted
- 1/4 cup oat milk
- plus, one passionfruit
- Whisk together the spread and vegetable fat.
- Add the icing sugar, 1/2 cup at a time with a splash of the oat milk, until fully combined and nice and fluffy.
- Sandwich the cakes together with the buttercream and the seeds and pulp of 1/2 a passionfruit.
- Spread the remaining buttercream on top and scatter over the seeds and pulp of the remaining 1/2 passionfruit.


I’d love a piece of that cake. Looks yummy!
