In a food processor, add the biscuits and blend.
Then add the melted butter and blend again until you get a sand-like consistency.
Place the biscuit and butter mixture in a tart pan or springform pan (I used a 24cm diameter round dish with a removable base) and then press down on an even layer to create a base.
For the date caramel, remove the pits from the dates and soak them in boiling water for 10 minutes.
Add the soaked dates in a food processor, along with 60ml of the soaking water and a pinch of salt and blend until you get a paste. Stop and scrape the sides of the blender as needed.
Spread the date caramel on top of the biscuit base in an even layer and place the pan in the freezer to set for a bit, until we are ready for the next step.
Peel and cut the bananas into slices and drizzle some lemon juice on top to prevent any browning.
For the cream, add all the ingredients in a large bowl and use a hand mixer to combine.
Add a layer of bananas on top of the date caramel, then add the cream and make swirls with a spoon to spread it around.
Use a vegetable peeler to add some chocolate shavings on top and refrigerate for at least an hour before you serve.
