- STEP 1
Make the biscuit base first. Melt the butter in a medium-sized pan. Put the biscuits into a food bag and crush with a rolling pin, or pulse them until fine in a food processor.
- STEP 2
Tip the biscuit crumbs into the melted butter until evenly coated. Pour the mixture into the centre of a 23cm/9inch loose-bottomed tart tin. Then press the mixture firmly over the base of the tin and up the sides. Transfer the base to the fridge to chill for about 30 minutes or until it is set.
- STEP 3
While the base is cooling make the caramel. Heat the brown sugar and butter together in a pan over a medium heat until the butter melts and the sugar has dissolved. At first the sugar and butter won’t mix, but keep stirring. As the sugar melts, it will come together.
- STEP 4
Stir in the condensed milk and the sea salt flakes. Bring up to the boil, then take off the heat.
Take the set biscuit base out of the fridge and pour the caramel onto the biscuit base. Transfer to the fridge and leave to cool completely.
- STEP 5
When ready to serve, slice the bananas and layer them over the set caramel. Pour the cream into a large bowl, and whip with electric hand beaters till thickened but not stiff. Spoon the cream over the bananas. Then grate the chocolate over the top.
