2Preheat your oven to 200°C (392°F). Score the chestnuts and roast them in the oven for about 20 minutes until the skins start to peel back.
Once roasted, peel the chestnuts and place them in a blender.
Melt the dark chocolate in a heatproof bowl over a pot of simmering water (double boiler method).
Add the melted chocolate, coconut milk, maple syrup, and cornstarch to the blender with the chestnuts.
Blend until smooth and creamy.
Pour the mixture into serving bowls or ramekins.
Refrigerate for at least 2 hours to set.
Serve chilled and enjoy your Vegan Chocolate Chestnut Pudding.
