Divide them between 3 clean jam jars, glasses, or dessert glasses/bowls.
Now make up your jelly in a jug. Pour the jelly powder into a large measuring just, then add 1 pint (568 ml or 2 cups) boiling water and stir well until the powder is well dissolved.
Pour the jelly into the three glasses and leave to set at room temperature for 1 hour.
Add a layer of custard to each pot (3 tablespoons of custard in each) and pop the desserts in the fridge to chill while you whip the cream.
In a large mixing bowl add the cold vegan cream (we like Elmlea Plant which whips well), icing sugar and vanilla extract, then whip until the cream is thick.
Dollop the whipped sweetened cream into each jar, then top each with a pinch of sprinkles, then chill in the fridge until ready to serve.
