Instructions

Step 1

The calculation in the recipe is for a 16cm (6.30 inch) mold.

Step 2

Sift all the dry ingredients together, then mix. Tip: Ensure there are no lumps in the flour and cocoa powder for a smooth batter.

Step 3

Add the milk, vegetable oil, and egg, then mix until combined.

Step 4

Pour in the boiling water and vinegar, then mix until the batter is smooth. Tip: Be careful while adding the boiling water to avoid splashes.

Step 5

Bake the sponge biscuit at 338°F (170°C) for 40-50 minutes. Tip: Check doneness with a toothpick; it should come out clean.

Step 6

Wrap the finished sponge biscuit in cling film and refrigerate overnight.

Step 7

In a frying pan, melt the sugar. Add the hot cream while stirring. Tip: Be cautious as the mixture will bubble up vigorously when adding the cream.

Step 8

Add the room temperature butter and chopped bananas. Hold the bananas in the caramel for a while, turning carefully to avoid mashing the pieces.

Step 9

Cool the caramelized banana mixture.

Step 10

Heat the cream for the ganache and pour it over the chocolate. Whip the mixture with a blender until smooth, then refrigerate for at least 4-6 hours.

Step 11

Whip all the ingredients for 'The cream' until homogeneous and thick.

Step 12

Cut the sponge biscuit into 3 layers. Tip: Use a serrated knife for more precise cuts.

Step 13

Assemble the cake in the following sequence: 1 cake layer, then some cream, followed by a cream rim, then the caramelized bananas, another cake layer, then some more cream, another cream rim, then the ganache, and finally the last cake layer.

Step 14

After stabilization, smooth the cake with the frosting.

Step 15

Whip all the ingredients for 'Frosting for leveling' until stable and uniform.

Faq

How do I avoid my sponge biscuit from sinking in the middle?
Ensure you don’t open the oven door during the initial stages of baking. Also, make sure all your ingredients are at room temperature before mixing.
Why did my caramelized bananas turn mushy?
Make sure your bananas are ripe but not overripe, and handle them gently while caramelizing.
Can I use milk chocolate instead of bitter chocolate for the ganache?
Yes, though it will result in a sweeter ganache. Make sure to adjust the sugar levels in your recipe accordingly.
Is it okay to frost the cake while it's still warm?
It's best to let the cake cool completely, or refrigerate overnight as suggested, before frosting to prevent melting and sliding layers.
How can I achieve a perfectly smooth frosting?
Use a bench scraper or a cake smoother and work with chilled frosting and cake layers. Patience is key—smooth in small sections.
Can I make the sponge biscuit in advance and freeze it?
Absolutely! Wrap it tightly in cling film and foil before freezing. When ready to use, thaw it in the refrigerator overnight.
