Easy vegan banana custard cake

Sorry, it's been a while since I posted a new recipe but trust me this cake is worth the wait! It's my new favourite because it's just so delicious! It looks more complicated than it is, but trust me it's really super easy. And the combination of all the flavours is really heavenly! The light sponge at the bottom, combined with the banana and then the list custard on top with chocolate drizzle. This is heaven on a plate. Honestly!

Step 1:

Mix together all dry ingredients.


Step 2:

Add wet ingredients to dry ingredients and mix together until you get a smooth batter without lumpgs.


Pour the batter into a greased baking dish (grease either with vegan butter or sunflower oil).

Bake in the preheated oven at 180C (360F) for 20 min.


Step 3:

Peel about 4 bananas and cut in half. Place them on top of the cake. Don't worry if the cake is still hot, there is no need to let it cool down.


Step 4:

To make the vegan custard blend all ingredients in this step (or you can whisk them as well, as long as there are no lumps). And then heat up in a pan until the starch gelatinises and you get a nice custard consistency. You don't have to add turmeric if you don't want to. I purely added it for the colour and admittedly added a bit too much of it so you could taste it in the cake. So do as I say and not as I do and add only a tiny amount of turmeric, not 1/3 spoon like in my video.  Tastewise it wasn't a problem but it would've been just a bit better without the hint of turmeric taste ;-)


Pour the custard on the cake and cover the bananas with it.


Step 5:

Add 50c cooking chocolate to a bowl and add 2 tsp sunflower oil (this will make the chocolate more smooth and prevents it from going hard again when it cools down). Microwave for about 1.5 min and then mix with a spoon until you get a smooth chocolate sauce.


Drizzle the sauce over the custard in a pattern of your choice, You can also make twice the amount of the chocolate sauce and fully cover the cake if you like.


Let set for about 2 hours or so in a cool place.


Enjoy this slice of banana custard heaven! ;-)
