Preheat your oven to 160°C (fan) or 180°C (conventional). Lightly grease a 9-inch tart tin.
In a food processor, combine the plain flour, vegan butter, molasses, ground ginger, cinnamon, allspice, nutmeg, and sea salt. Pulse until a crumbly dough forms.
Shape the dough into a disc, wrap in cling film, and chill in the fridge for 30 minutes.
Roll out the chilled dough and press it into the tart tin, trimming the edges and pricking the base.
Blind bake the crust with parchment paper and weights for 12 minutes, then remove weights and bake for another 10–12 minutes until golden.
Chop dark chocolate into a bowl. Heat coconut cream in a saucepan until simmering, then pour over chocolate and let sit for 5 minutes.
Whisk until smooth, then stir in maple syrup, molasses, ground ginger, and a pinch of salt.
Pour ganache into the cooled tart crust and refrigerate for at least 4 hours, or overnight.
Garnish with optional toppings before serving.
Notes
For a perfect tart, chill the crust well before rolling it out. Consider adding chopped nuts to the crust for texture.
