Instructions

1

Blend everything — add bananas, milk, and cocoa powder to a blender. Blend on high for 60 seconds until completely smooth and silky. For an extra smooth result, strain through a fine sieve.
2

Cook on medium heat — pour the mixture into a saucepan. Stir continuously for 5–8 minutes until the mixture thickens noticeably. Don't stop stirring or it will catch on the bottom.
3

Pour into mold — transfer into a greased silicone mold or lined baking dish. Smooth the surface with a spatula. Tap gently on the counter to remove air bubbles.
4

Refrigerate for at least 4 hours or overnight until completely set and firm throughout.
5

Invert onto a serving plate. Peel away the mold or paper slowly. Add optional toppings like fresh berries or chocolate shavings. Enjoy! 🍫✨

Pro Tips for Perfect Results

🍌
The riper the bananas the better — black-spotted bananas are the sweetest and give the most intense natural sweetness. No maple syrup needed!
🫙
Strain for silkier texture — pour through a fine mesh strainer after blending for a completely smooth, professional-quality mousse.
🌡️
Stir constantly while cooking — the mixture can catch on the bottom quickly. Medium heat and continuous stirring is the key to a smooth result.
⏰
Overnight chilling is best — 4 hours is the minimum but overnight gives a firmer, more sliceable cake that holds its shape.

❓ Frequently Asked Questions

Can I taste the banana?

Slightly — very ripe bananas have a subtle, sweet flavour that blends beautifully with cocoa. The rich chocolate is the dominant taste you'll notice.

What milk works best?

Full-fat dairy milk gives the creamiest result. Oat milk adds a subtle sweetness. Coconut milk creates the richest, most indulgent texture — all three work!

My cake didn't set firm — what went wrong?

It needs to cook longer on the hob — the mixture must thicken significantly before chilling. Cook for 8–10 minutes until it coats the back of a spoon.

How long does it keep?

Up to 3 days in the fridge covered with cling film. The flavour actually deepens and improves on day 2!
