“The major change in this recipe is the egg replacement (shocking news, there is none) and substituting the soured cream,” former Bake Off finalist Ruby Bhogal says of how she adapted this recipe to be plant-based.

“For that, I have offered up a suggestion that will give you that dense, incredibly moist and tender crumb.

“The best thing about this sponge is you still get that same sticky texture and spiced flavour, but without all the faff of having to work the air into the butter and sugar. Work smarter, not harder.”

Ingredients:(Serves 10-12)

For the sponge:200ml soy milk1tbsp cider vinegar260g plant-based unsalted butter210g dark soft brown sugar100g golden syrup100g black treacle1½tsp vanilla bean paste4 pieces preserved stem ginger, finely diced, plus some syrup from the jar for brushing400g self-raising flour, sifted¼tsp bicarbonate of soda2tbsp ground ginger1½tbsp ground cinnamon

For the butterscotch filling:150ml plant-based double cream75g light soft brown sugar40g plant-based salted butter, cubed1tsp cornflour, siftedPinch of sea salt

For the whipped cream cheese frosting:250g plant-based cream cheese50g caster sugar1½tsp vanilla bean pasteGrated zest of 3 large oranges400ml plant-based double cream3x18cm cake tins, greased with coconut oil and lined (base and sides)

Method:

1. Preheat the oven to 150°C fan/170°C/gas mark 3.

2. Add the soy milk and cider vinegar to a bowl and leave to sit for 10 minutes until lightly curdled. In the meantime, add the butter, sugar, golden syrup, treacle and vanilla bean paste to a saucepan and gently heat until the butter has melted and the sugar has dissolved. We don’t want this boiled, so take it low and slow. Remove from the heat and add the stem ginger. Give it all a good mix and set aside to cool.

3. In a large bowl, combine the dry ingredients with a balloon whisk. Pour in the cooled butter mix and the curdled soy milk, and mix until smooth. Divide the cake batter evenly amongst the three prepared tins. Pop in the oven and bake for 26-28 minutes until the sponge is coming away from the sides of the tins and a cocktail stick poked into the middle comes out clean.

4. Leave in the tins for five minutes before turning out onto a cooling rack. Leave to cool for 30 minutes before wrapping in clingfilm to cool completely. While the cakes are cooling, make the butterscotch filling. In a saucepan, add the cream, light brown sugar, butter and cornflour.

5. Cook over a gentle medium heat until the sugar has dissolved, the butter has melted, and the liquid begins to bubble. Take off the heat, add the sea salt (just a tiny pinch!) and give it a mix before transferring to a bowl to cool. Once cooled, pop the bowl into the fridge to firm up, which makes it easier when stacking the sponges.

6. Let’s get the frosting made. Into the bowl of a stand mixer, add the cream cheese, sugar, vanilla bean paste and orange zest. Mix using the whisk attachment until smooth. Pour in the double cream and mix on a slow-medium speed until the cream nearly hits stiff peaks. Transfer to a piping bag and place in the fridge for at least 30-45 minutes before using.

7. Once the sponges are cool, trim off any domed tops with a serrated knife before using a pastry brush to brush the tops of each sponge with syrup from the stem ginger jar.

8. Now it’s time to construct the cake by placing one sponge onto your serving board (you can use some cream here to glue the sponge to your serving plate). Pipe an even layer of cream over the sponge before using the back of a spoon to create a dip in the middle to add a generous slathering of the butterscotch filling. Repeat with the remaining sponges before covering the entire cake with the remaining cream. You can go as fancy as you like with the decoration or opt for a naked finish.

9. Place the cake in the fridge to set for at least an hour before slicing and serving with a good drizzle of any remaining butterscotch sauce.
