The backstory of this chocolate banana cake
The idea for this cake came after I started reminiscing about the types of cakes my mum used to make when I was young. Layered cakes were something she used to put together often and at the last minute when unexpected guests were just around the corner or for my family to enjoy.
I love fruit layers in a cake. It adds another dimension to the dessert, creates balance, and adds freshness. If you also love this idea, you can try a few of my other desserts that use fresh fruit. Here’s a quick list:
- Vegan Vanilla Cake with Coconut Cream and Berries
- Vegan Trifle Cups with Berries
- Raw Vegan Zesty Lemon Slice
If you’d like to add fruit to your baked dessert, I have an extensive range of fruit-based sweets you can browse.
Let’s break down the layers in this vegan cake
Chocolate cake
The chocolate cake layer is a simpler version of my classic chocolate cake recipe. Since there are a few layers here, I wanted to make it as approachable as possible. You only need a handful of pantry staple ingredients, and you’re ready to go!
You can use this cake as a base for many other desserts.
Bananas
For this recipe, you’ll need 2-3 bananas. It just depends on their size. I like to use ripe bananas that are lightly spotted but not completely brown. You want them to hold their shape in the cake but not be so firm that you can’t cut through easily with a spoon or fork. Riper bananas are also sweeter.
Custard
The custard layer is essentially my simple custard recipe with an increased amount of cornstarch. I add more cornstarch to this custard to ensure that once it sets, it is firm enough to slice and keep its shape. Please make sure you use cornstarch; it’s a super fine white powder that makes a squeaking noise when rubbed between your fingers. Any other corn product won’t work.
Cream
You may have noticed a pattern of re-purposed recipes within this one. Well, the cream is no different. With minor tweaks, I’ve utilised my whipped coconut cream recipe. I swapped out the maple syrup for icing sugar for two reasons. To make the overall cake sweeter and to add structure to the cream. If you have access to vegan whipping cream, you can swap it out, but remember that it may not set as well as this one.
Shaved chocolate
Adding shaved chocolate to the top ties in the chocolate flavour with the chocolate base and finishes it off nicely. You can swap it out for hot chocolate powder or plain cacao powder and dust it over the top. This is a great alternative if you’d like to make the cake less sweet. I used a chocolate block I bought from my local bulk store (a standard chocolate bar will also be fine) and a shaver to achieve the look. If you want, you can grate it over instead.
A few variations and tweaks you can easily make
I love this cake the way it is. However, if you’d like to try it with some tweaks, you can try the following:
- Swap the bananas for strawberries, mangoes, pears (the softer varieties), kiwi fruit, raspberries, or morello cherries (drain them well first).
- Swap the chocolate cake for my vanilla cake as the base (make sure you halve the recipe).
- Want more chocolate? Turn the vanilla custard into chocolate custard by adding about ¼ cup of chopped chocolate to the pot when you’re cooking it. You need enough heat to melt it and incorporate it in. About 2 minutes before it’s finished.
- As I mentioned earlier, you can swap the coconut cream for a vegan whipped cream instead. Just keep in mind that it may not set as well as the coconut one when chilled.
Unlike traditional round cakes, this one is easy to layer inside the baking dish and helps with slicing.
The cake also doesn’t look large but can comfortably serve 16 people. You can make the slices more generous if you like and add different decorations to the top if you’d like to use it as a birthday or celebration cake.
So, give this chocolate banana custard cake a try next time you want to create a crowd-pleasing vegan sheet cake that looks fancy but is easy to make.
I have shared this cake with my neighbours, who all love it! It will keep in the fridge in an airtight container for up to 4 days.

Ingredients
Chocolate cake
Dry:
- 1 cup / 135g plain all-purpose flour
- ¾ teaspoon baking powder
- ¼ teaspoon bicarb soda
- 2/3 cup / 160g cane sugar (organic if in the US to make sure it’s vegan)
- ⅓ cup / 30g cacao powder
- Pinch salt
Wet:
- ½ cup / 110ml espresso or strong coffee (preferably freshly made and still warm)
- ½ cup / 125ml plant milk
- ¼ cup / 50ml neutral oil (like rice bran or grapeseed)
- ½ teaspoon apple cider vinegar
Custard
- 2 cups / 500ml plant milk
- ⅓ cup / 35g cornstarch
- ½ cup / 100g cane sugar (organic if in the US to make sure it’s vegan)
- ½ cup / 120g coconut cream (or full-fat coconut milk)
- 1 teaspoon vanilla extract
- Pinch turmeric (for colour, you won’t taste it)
Coconut cream
- 2 cups / 440g coconut cream
- 3 tablespoons icing sugar (powdered sugar)
- 1 teaspoon vanilla extract
Extras
- 2–3 ripe bananas (depending on size)
- Vegan block chocolate, for shaving
Instructions
Chocolate cake
- Preheat the oven to 180 degrees Celcius (355 degrees Fahrenheit) and place the rack in the middle. Line a 9x9inch square pan (or similar) with parchment paper, grease the sides for easy removal, and set aside.
- Sift all the dry ingredients in a bowl and whisk together to combine well.
- In a smaller bowl, combine all the wet ingredients and whisk them until they are well combined and slightly frothy.
- Pour the wet ingredients into the dry and mix using a whisk until there are no lumps. Please don’t over-mix!
- Place on the middle rack in the oven, baking for 25 minutes. Bake until the skewer comes out clean when inserted into the middle of the cake. Please don’t be tempted to open the oven any sooner, as this will make the cake collapse in the middle as it cools. You want the cake to spring back if you touch the top.
- While the cake is baking, make the custard and coconut cream.
Custard
- Add 1 cup (250ml) of the milk to a medium-sized saucepan and place on medium-high heat until the milk warms up.
- In the meantime, add the rest of the milk and the custard ingredients to a bowl and whisk until well combined.
- Once the milk has come to a gentle simmer, pour in the custard mix and whisk for around 4-5 minutes until it thickens or starts to stick to the bottom of the saucepan. You will feel it.
- Whichever occurs first, reduce the heat to low and cook, stirring for 2 minutes. (If the custard is too thin, keep cooking until it thickens).
- Remove the saucepan from the heat and set it aside.
Coconut cream
- Scoop the coconut cream from the can into a bowl. Only use the thick, creamy part.
- Add in the icing sugar and vanilla extract, and using an electric whisk, whisk it for a minute until well incorporated and fluffy.
- Set aside.
Now all your components are ready. Slice the bananas into thick coins and place them over the chocolate cake (still in the baking dish), then pour over the custard. Let the custard set and cool before layering it with coconut cream. Spread it out evenly and chill for 2-3 hours to set completely. Once ready, shave the chocolate over the top and cut it into serving portions.
