When I got my first apartment, it was in Toulouse, I often went to a tea room to have afternoon tea after classes. I alternated between my two favorite cakes there: the raspberry-pistachio tart and the banoffee 🥰 It's still one of my favorite desserts: a base of crushed biscuits (I use speculoos), caramel, bananas, and lots of whipped cream! It's super simple to make. The only little tip I would give you is to let the finished banoffee rest in the fridge for several hours (or even overnight if you want) before serving it, so you can cut neat slices and the whipped cream doesn't move around ;)
