Cover an 8-inch pan with plastic wrap (clingfilm) leaving some hanging over as excess.
To make the base, place the almonds and coconut in a food processor and blitz the ingredients together until you're left with a damp rubble.
Add in the dates and coconut oil, then mix for a few more minutes or until the mixture comes together, forming a mass.
Press the mixture into the prepared pan and about 1.5 inches (2.5 cm) up the sides, then place in the freezer to set, until solid.
In the meantime, prepare the salted caramel filling.
If the dates are very dry, cover them with boiling water (see video!) and let them sit for 5-10 min.
Remove the states from the water, and place the dates into a food processor along with 1/4 cup of the soaking water, salt and vanilla. Keep the water handy. If the mixture is too thick, you can add more water.
Blend the ingredients together until the dates are completely smooth and the mixture and form a nice, toffee-like paste. Add more salt/vanilla if desired.
Slice the bananas and sprinkle atop the lemon juice to prevent them from browning.
Next make the coconut whipped cream (see notes for what it is).
Place the chilled coconut cream into a bowl.
Whip using an electric mixer or hand held whisk until it has doubled in size and the mixture forms nice peaks.
Gently mix in the maple syrup and vanilla extract.
To assemble the pie, gently remove the plastic wrapped base from the cake tin, then peel it off of the base. Because the base was in the freezer, it should be nice and firm.
Pour the date caramel into the base and spread evenly to cover the inside entirely.
Scatter atop the banana slices, covering the date caramel entirely.
Dollop atop the coconut whipped cream, creating peaks using your knife or spatula for a nice finishing effect (see the video).
Dust with cocoa/cacao powder or scatter atop some raw cacao nibs or grated chocolate (vegan chocolate if vegan).
Serve cold. Because this dish has fresh fruit, it won't last more than a few days once you assemble it. I recommend making the base and dates caramel ahead of time- the coconut whip and bananas should be prepared the day of/day before serving. The base keeps well in the freezer for up to 2 months, as would the date caramel.
