An indulgent chilled chocolate cheesecake thickened with creamy-textured chestnut purée, and lightened with whisked OGGS Aquafaba. Set on a chocolate and gingernut biscuit base, this makes an impressive celebration dessert. We like to use Doisy and Dam 70% chocolate. The Coconut and Lucuma flavoured chocolate enhances the coconut flavour of the dairy-free cream cheese and yogurt we used, but Orange and Goji berry or Maca, Vanilla and Cocoa Nibs would work brilliantly too. Any 70% vegan chocolate would work well.
For the Crumb
- 75g vegan spread eg Stork, Flora or Naturli, plus extra for greasing
- 30g dairy-free dark chocolate, minimum 70% solids, broken into pieces
- 250g vegan-friendly gingernuts (McVities are vegan)
For the Cheesecake
- 130g dairy-free dark chocolate, broken into pieces
- 50g ginger syrup from a jar of stem ginger in syrup
- 100g unsweetened chestnut purée (we like Merchant Gourmet)
- 150g vegan cream cheese, such as Nush, Koko (we used Sainsbury’s Free From Original coconut-based alternative to cream cheese)
- 150g dairy-free yogurt (we like Coconut Collaborative natural yogurt alternative, Alpro Greek style works well, too)
- 100ml OGGS Aquafaba
- The peel of 1 orange, cut into fine strips
- Caster sugar
- Small handful dried or fresh cranberries
1. Grease and line the base and sides of a deep 20cm loose-bottomed tin.
2. Bring a pan with 2cm water up to a very gentle simmer. Put the spread and the chocolate for the crumb into a bowl that fits snugly over the pan and stir it till it has melted. You don’t want to let any water get into the mixture.
3. Meanwhile, put the biscuits in a loosely sealed bag and crush with a rolling pin, or the base of a saucepan, or whizz in a food processor if you have one.
4. Stir the biscuit crumbs into the melted chocolate mixture and press into the base of the prepared cake tin. Pop into the fridge to firm up while you make the filling.
5. Now wash the bowl and melt the chocolate for the cheesecake in it over the same pan of simmering water, stirring to melt. Carefully remove from the heat and allow to cool slightly.
6. Stir the syrup from the ginger jar into the melted chocolate, along with the chestnut purée and mix until smooth; it will thicken slightly. Now beat in the cream cheese until there are no lumps, then finally stir in the yogurt until everything is completely combined.
7. Pour the OGGS Aquafaba into a large super-clean grease-free bowl and whisk for a minute or so with an electric mixer until it becomes frothy, forms soft peaks and is full of air. Spoon some of the whipped Aquafaba into the thick chocolate cheesecake mixture to loosen it, then fold in the remainder so that it is well combined with no white streaks. Pour it into the tin and smooth it carefully over the chilled biscuit base to the edge with the back of a spoon to give a level top.
8. Pop the cheesecake into the fridge and leave to set for a minimum of 3 hours or overnight if preferred.
9. When the cheesecake is set, carefully push up the base to remove from the tin. Carefully remove the baking paper. Transfer to a serving plate. Wrap the strips of orange around the end of a wooden spoon to make a curl then toss in a little bowl of caster sugar. Carefully arrange on the top of the cheesecake, setting a few cranberries in the middle, too.
10. Once decorated, the cheesecake will keep in the fridge for 1-2 days.
