Crush the cookies into fine crumbs and put into a bowl
Melt the margarine and mix it into the crumbs
Pack the crumbs into the base of a 9" springform cake tin and let chill in the fridge for 15 minutes
Mix the vanilla pudding with the coconut milk. It will be very thick. (If you can't find a box of Jello Pudding (I get mine from Amazon), Birds tubs of custard powder are free-from. Make a thick custard using 2 heaped tablespoons of powder and as much milk as it needs. Let it cool.) Spread it on top of the crumb base and put in the fridge to set
Pour the raspberry ice cream syrup over the set pudding layer. You could use rasperry jello / jelly but it doesn't stick very well to the custard pudding layer so I find sauce works better. You could also try seedless jam, warmed slightly. You don't need to use the whole thing, just enough so there's an even layer of it
Mix the sherry with the whipped cream for topping and put into a piping bag. Set aside. (Chill a tin of full fat coconut milk in the fridge overnight then in the morning it will have separated. Drain off the coconut water and whisk the cream until stiff)
Cut your cake horizontally into 2 or 3 layers. You can always freeze the spare layers or make more cheesecake trifle desserts and freeze the others for later! Place the cooled sponge disc on top of the sauce then pipe on the whipped coconut topping
Release from the tin and garnish with some grated dark chocolate just before serving
