Vegan Banana Cake
A moist vegan banana cake that truly rivals the classic. Ripe bananas bring natural sweetness, structure, and binding power, while soy lecithin and Lab-Whip create the light crumb usually achieved with eggs. Coconut milk and oil add richness without heaviness, and a touch of cinnamon and brown sugar deepen the flavour and colour, mimicking the Maillard notes of traditional cakes.
After four rounds of recipe adjustments, this version of my vegan banana cake finally hits the mark — a commercial-grade vegan cake with the same tender texture, balanced flavour, and golden finish as a banana cake made with eggs. Simple enough for home bakers, yet technically refined for consistent, professional results.
Instructions on how to make a Vegan Banana Cake
STEP 1
In a stand mixer with a flat paddle mix together the bananas, two sugars, lab whip and soy lecithin. When white and light add in the oil slowly and then the coconut milk
STEP 2
Add in the combined dry ingredients ensuring the bicarbonate of soda is sifted. Mix on a low speed until combined. Scrape the sides.
STEP 3
grease and line a loaf tin. Add the banana mix ready for the oven .
STEP 4
Bake at 200C for 35-40mins until the top is caramelised. Reduce the temperature to 150C and bake until the middle is set but still wobbly.

Equipment
Method
- Preheat oven to 175°C (350°F).
- Grease a loaf tin and line the bottom with baking paper.
- Mash bananas in a large bowl until smooth.
- Add Bananas and whisk in the two lots of sugar, with the lab whip and soy lecithin .Once light and white add in the oil slowly and then the coconut milk.
- In a separate bowl, mix flour, Bicarbonate of soda(sifted ),Cinnamon and salt.Fold dry ingredients into the wet until just combined (don’t over mix, gluten will toughen the loaf).
- Pour into prepared tin. Bake for 55–60 minutes, or until a skewer comes out clean or the internal temperature is 85C.
- Cool in tin for 10 minutes, carefully tip out and then transfer to a rack.

Fun At-Home Testing: Vegan Banana Cake
The Ripeness Test
Try using bananas at different ripeness levels.
Yellow with freckles: balanced sweetness and firm crumb.
Overripe and dark: stronger banana aroma and moister texture.
Compare which version gives the best flavour and structure.
The Flour Strength Test
Bake one loaf with plain flour and another with wholemeal or spelt flour.
Notice how the denser flours affect lift and moisture. Record differences in rise, colour, and texture.
The Sweetener Swap
Try replacing part or all of the brown sugar with allulose or coconut sugar.
See how each affects:
Colour: allulose browns beautifully; coconut sugar deepens colour.
Texture: lower-sugar versions may hold more moisture.
The Milk Trial
Swap coconut milk for soy, almond, or oat milk.
Observe the crumb structure and flavour—soy gives lift, oat adds sweetness, almond keeps it light.
The Doneness Test
Insert a skewer at 50, 55, and 60 minutes.
Note when it comes out clean and when the top springs back. You’ll see how baking time influences colour, crust, and internal moisture.
The Freeze–Thaw Challenge
Slice a cooled loaf, freeze overnight, and thaw.
See how the texture holds up—this shows how moisture and emulsifiers (like lecithin or Lab Whip) protect structure in commercial baking.

Storage for the Vegan Banana Cake
Storage Tips – Vegan Banana Cake
Room Temperature:
Store the cooled banana cake in an airtight container for up to 3 days at room temperature.
Keep it in a cool, dry place away from direct sunlight to prevent excess moisture and mould growth.
Refrigeration:
For longer freshness, refrigerate for up to 5–7 days.
Wrap tightly in baking paper or cling film to prevent the crumb from drying out.
Allow slices to come to room temperature before serving for the best flavour and texture.
Freezing:
Slice the cake once cooled and wrap each slice individually in cling film or compostable wrap.
Store in an airtight container or freezer bag for up to 2 months.
To serve, thaw at room temperature for 1–2 hours, or warm briefly in the microwave (10–15 seconds) for a just-baked texture.
Pro Tip:
Add a small piece of paper towel inside the container to absorb condensation and help maintain the soft crumb.
Fun Facts – Vegan Banana Cake Edition
Bananas were once called “nature’s custard.”
Their creamy texture and sweetness made them a natural stand-in for eggs and dairy long before vegan baking became trendy!
The riper the banana, the sweeter the bake.
Banana starch converts to sugar as it ripens, which is why those dark, spotty bananas give the best cake flavour.
Your cake’s aroma changes overnight.
Banana volatiles (isoamyl acetate and eugenol) intensify as the cake rests — that’s why banana cake often tastes better the next day!
Allulose caramelises like sugar — but with 90% fewer calories.
A modern baker’s dream: rich flavour, lovely browning, and less guilt.
Cinnamon isn’t just for flavour.
It subtly enhances perceived sweetness, meaning you can use less sugar without losing that cosy dessert vibe.
Coconut milk adds body and shine.
Its natural fats mimic the richness of butter, giving your vegan cake that tender crumb and golden finish.
Bananas were first baked into loaves during the Great Depression.
Home cooks used overripe bananas to reduce waste — a tradition that continues in modern sustainable baking.
Vegan banana cake travels well.
Low dairy content and balanced moisture make it perfect for picnics, cafés, and school lunchboxes — no fridge needed for a few days!
FAQs For the Vegan Banana Cake
. Can I use any type of banana?
Use ripe bananas with plenty of brown freckles. They’re sweeter and mash more smoothly, giving your cake better flavour and structure. Overripe (black-skinned) bananas work too but can make the crumb denser and slightly darker.
Why did my vegan banana cake sink in the middle?
Usually from too much moisture or underbaking. Check banana weight (too many makes it heavy) and bake fully until the centre springs back. Also make sure your bicarbonate of soda is fresh — it’s your only leavening agent here.
Can I reduce the sugar?
Yes. Replace brown sugar with allulose or a mix of allulose and coconut sugar to lower the sugar load. Allulose gives good browning and moisture retention, but slightly softens the crumb.
What milk works best?
Coconut milk gives the richest result, but soy or oat milk provide structure and balance. Almond milk keeps it light, and rice milk works if you increase emulsifiers slightly (e.g., add 1–2 g more lecithin).
Can I make it gluten-free?
Yes — swap plain flour for a 1:1 gluten-free flour blend with xanthan gum or CMC (carboxymethyl cellulose.) The crumb will be softer, so reduce liquid by about 5%.
How do I know when it’s baked?
At 175 °C for 50–55 minutes, the cake should have a golden top and a clean skewer. The centre should spring back lightly when pressed.
Can I freeze vegan banana cake?
Absolutely. Slice once cooled, wrap each slice, and freeze up to 2 months. Thaw at room temperature or warm for 10–15 seconds before serving.
Why does my banana cake turn darker after baking?
Banana enzymes (polyphenol oxidase) react with oxygen and natural sugars during baking — it’s harmless and actually adds depth of flavour.
Can I add nuts or chocolate chips?
Yes! Stir through chopped walnuts, pecans, or dark chocolate chips just before baking. Reduce banana slightly (about 30 g) to balance moisture.
