Preheat oven to 190 degrees (or 170 degrees fan bake) and line a cake tin with baking paper, about 18cm.
Place coconut oil in a heatproof bowl and heat in the microwave for 30 seconds at a time, until melted. Add the Banoffee Pie Base Mix, pumpkin seeds and first measure of maple syrup to bowl and mix together.
Press mixture into the bottom of prepared cake tin, bringing it up the sides slightly. Bake for 12-15 minutes, until golden.
Take the base out of oven and fill with Date Caramel. Bake in the oven for a further 12-15 minutes, until it is golden and bubbling. Allow to cool completely.
Slice banana into 1cm pieces and assemble on top of caramel. Drizzle with second maple syrup measure.
