Vegan chocolate yule log

Heat the oven to 180C/160C fan/gas 4 and line a swiss roll tin (approx. 32cm x 22cm) with baking parchment.

First, make the ganache by combining the silken tofu and dark chocolate in a medium saucepan over a low heat, stirring until the chocolate has melted – it will look lumpy at this stage but don’t worry. Add the maple syrup, vanilla extract and a pinch of salt, stir to combine and take off the heat. Use an electric whisk to transform the mixture into a silky smooth ganache, about 2-3 mins. Transfer to a piping bag and put in the fridge to cool.

To make the sponge, sift all the dry ingredients (flour, cocoa powder, caster sugar, baking powder, cornflour, bicarbonate of soda and ½ tsp salt) together in a mixing bowl. In a small jug, combine the oat milk and vinegar to create a vegan buttermilk. Set aside.

In a separate mixing bowl, whisk the aquafaba until the liquid has transformed to soft peaks – be patient as this can take up to 5 mins. It’s best to use an electric handheld whisk or freestanding mixer.

Add the vegetable oil and vanilla extract to the jug of oat milk and vinegar. Pour the wet ingredients into the bowl of dry ingredients and use large metal spoon to combine until you have a thick batter. Stir a third of the whipped aquafaba into the batter. Once the batter has loosened slightly, tip the chocolate batter into the bowl with the remaining aquafaba and fold through until combined, being careful not to knock too much air from the mixture. Pour this into the prepared baking tin, level out with a spatula, and bake for 20-22 mins.

Leave the sponge in the tin to cool for 5 mins before turning it out onto a large piece of parchment dusted with 1 tbsp icing sugar. Peel off the top parchment used to line the tin and leave for a further 2-3 mins to cool slightly. While still slightly warm, use the baking parchment to roll the sponge from the short end, creating a log. Carefully unroll and allow to cool completely – rolling the sponge while slightly warm helps prevent large cracks. But don’t worry if there are small cracks as they’ll be hidden by the ganache.

For the filling, whisk the icing sugar, vanilla extract and plant-based double cream in a bowl until soft peaks have formed. The sponge should now be cool. Spread an even layer of the cream over the flat sponge. Then, as before, roll the filled sponge into a log and use the baking parchment to hold in a log shape. Transfer to a plate or board and into the fridge for 30 mins-1 hr.

When you are ready to decorate, carefully unwrap the yule log from the parchment. Snip the end of the piping bag and pipe thick horizontal lines to cover the sponge with chocolate ganache. Use a spoon to create a soft pillowy finish to the ganache, or a fork to create a bark-like effect. Finish with any accompanying decorations – berries, edible holly décor or a spritz of gold spray. Transfer to the fridge for at least 1 hr or until you’re ready to serve.

Serve with more pouring cream and berries, if you like.
