Yes, there are a gazillion banana cake recipes on the internet. I have no idea why it's often called banana 'bread'. Maybe it tricks people into thinking this is health food? I’m not even going to try and claim there’s anything particularly different or special about this one. 😆 I’ve been waiting for an opportunity to use the banana emoji.
Why is this banana cake so good?
- No need for a mixer. Hands only.
- Perfect way of using up overripe bananas.
- Two-bowl recipe – one for dry ingredients, one for wet.
- 15 minutes prep only.
- Very adaptable. Adjust the flour, fat and sweetener type based on what you have or prefer.
- Freezes well. Great for lunchboxes.
I like this banana cake recipe because it *kind of* healthy – lots of banana, not too much sugar. Let's say that banana is a given, the other ingredients are very adaptable. You can use a bit of one thing and some of another. You can use any type of flour – I’ve used gluten-free, strong (bread) flour, white or wholemeal. You can use any type of sweetener – brown or white sugar, honey, maple syrup. You can vary the fat – butter, olive oil, coconut oil. The recipe below is the way I make it the most.
Banana is probably a given, but most of the other ingredients are very adaptable.
I’ve reduced the sugar compared to many recipes out there. If you use super-ripe bananas for this, they add a lot of sweetness. Some recipes call for creaming the butter and sugar. I don’t feel like this is necessary for this dense, moist cake; we’re not trying to achieve light and fluffy here.
A low oven temperature helps prevent a crust. Banana cake should be moist and soft all the way through.
However you make it, banana cake improves with time. Try and remember to bake it a day ahead.
🥘 Ingredients
Butter – substitute with a vegetable oil (including olive oil) or coconut oil.
Wholemeal Flour – wheat or gluten-free. Or white.
Oat Bran – adds a nutty flavour and slightly chewy texture. Substitute with wheat bran or with the same weight of your choice of flour.
Soft Dark Brown Sugar - adds rich flavour, deeper colour and moistness. Substitute with the same amount of white sugar or sweetener of your choice.
Bicarbonate of Soda/Baking Soda – works with the buttermilk (or equivalent) to produce gas, for a lighter texture.
Buttermilk – easily found in the dairy section of most supermarkets. If you don’t have any, you can make your own. Use the same amount of any type of milk mixed with 1 ½ teaspoons of lemon juice or white vinegar. Leave to rest for 5-10 minutes before using. It will curdle slightly (which is what we want).
Bananas – yes, they look disgusting in the photo! They’re very ripe bananas that I have peeled, frozen and defrosted overnight for this recipe. Use fresh ones if you have, but the riper the fruit is, the sweeter the banana bread will end up.
Never throw away over-ripe bananas. Freeze them.
You can leave bananas whole or break into smaller chunks before or after freezing. They’re quite soft even frozen and you’re going to get mashed them for the cake later anyway. Over-ripe bananas are perfect for this recipe – super sweet and soft. Make sure you defrost before using (in a bowl). They’ll look horrible and will release brown juice, but don’t be put off. Include it, flesh and juice (it was all there in the fresh banana, after all). You can use all fresh bananas, all frozen (and defrosted) or a bit of both to make up the total weight of the bananas. Fresh bananas have a little more texture - you can choose to keep some pieces bigger.
🔪 Instructions
Dry Ingredients – simply combine in a large bowl (big enough to take all the ingredients). Flour, sugar, bicarbonate of soda, ground cinnamon and nutmeg and salt.
Wet Ingredients – simply combine in another bowl. I melt the butter directly in this (microwave-safe) bowl to save on washing up. Let the butter cool down before you add buttermilk and egg, particularly if these are fridge-cold. The butter will solidify into little lumps otherwise. For this reason, I recommend melting the butter first. Leave it to cool while you get the dry ingredients organised.
Combine!
Pour the wet ingredients over the dry. It’s easier to do this way around. Combine and pour into a prepared loaf tin. I’ve used the bulldog clip to hold the greaseproof paper out of the way while I poured the batter into the tin. I forgot to remove it for the photo 🙄. Don’t put plastic bulldog clips in the oven!
Top with banana slices
Of course, you don’t have to put slices of banana on the top. If you’re using bananas from the freezer, you won’t be able to slice them anyway. It does look pretty though and is a visual clue as to what type of cake this is. Don’t worry if the slices break (it’s quite hard to thinly slice a soft curved banana). If this happens, patch it together on the top of the cake. I find it best to have the two slices ‘spooning’ each other i.e. curving the same way. I’ve found it can look a bit vagina-esque otherwise. Maybe that’s just the way my mind works. Bet you can’t unsee it now. You’re welcome!
Sprinkle and bake
Sprinkling with a little demerara (raw) sugar adds a bit of colour and crunch. Bake for around an hour until a cake tester/skewer come out clean.
If you enjoy quick two-bowl bakes, try my blueberry muffins recipe. Wet ingredients in one bowl, dry in the other, combine and bake. Serves of fruit in sweet bakes makes for a balanced diet, right?
📖 Recipe
Equipment
- Small loaf tin
Ingredients
- butter for greasing
- 85 g unsalted butter
- 200 g wholemeal flour
- 100 g soft dark brown sugar
- 60 g oat bran
- teaspoon bicarbonate of soda
- teaspoon ground cinnamon
- ½ teaspoon salt
- ¼ teaspoon ground nutmeg
- 115 g/ml buttermilk
- 1 egg
- teaspoon vanilla extract
- 400 g ripe/very ripe bananas (approx. 4 medium)
- teaspoon demerara (raw) sugar
Instructions
- Preheat Oven – to 150°C.
- Prepare Tin - lightly grease the loaf tin with butter. Line the base with baking paper long enough to go up opposite sides of tin with some overhang.butter
- Butter - melt the butter and allow to cool. You can microwave it directly in a medium non-metallic bowl.85 g unsalted butter
- Dry Ingredients - combine in another large bowl (big enough to take all the ingredients). Tip in the flour, sugar, oat bran, bicarbonate of soda, cinnamon, salt and nutmeg. Use a handwhisk or fork to combine. If you’ve used soft brown sugar, it can tend to clump up because it’s a bit damp. If you shimmy the bowl backwards and forwards on the counter, any lumps of sugar will rise to the top. Rub these between your fingers to break up and stir through.200 g wholemeal flour100 g soft dark brown sugar60 g oat branteaspoon bicarbonate of sodateaspoon ground cinnamon½ teaspoon salt¼ teaspoon ground nutmeg
- Egg, Vanilla & Buttermilk - add buttermilk, egg and vanilla to the melted butter. Whisk well to combine.1 egg115 g/ml buttermilkteaspoon vanilla extract
- Bananas – (if using fresh bananas, cut a couple of thin slices along the length of one and reserve for the top of the cake). Mash any fresh bananas with a masher or the back of a fork directly on a chopping board. Defrosted bananas will be wetter; you can mash on a plate or in a bowl. Add the mashed banana to the other wet ingredients and mix in well.400 g ripe/very ripe bananas
- Mix Wet & Dry - pour wet ingredients over dry. Combine with a flexible spatula until just combined and no dry flour is visible.
- Bake – pour the batter into the loaf tin and smooth the top. Create a little ditch in the middle. Gently place the reserved banana slices on top (if using). Sprinkle the demerara sugar over the top of the cake. Bake for around 1 hour, until a skewer inserted through the centre comes out clean. Leave the cake to cool in the tin for a while before removing using the paper ‘handle’.teaspoon demerara (raw) sugar
