When it comes to lavish, chocolatey, indulgent celebration cakes, vegans really don’t need to miss out! Although this looks like it might be a difficult bake, a little application with the three layers plus the icing and drizzling decoration and you’ll have a real showstopper to be proud of.
Dry ingredients
525g plain flour
120g coco powder
70g oatmeal
1tsp salt
3tsp bicarbonate of soda
500g dark brown sugar
175g caster sugar
Wet ingredients
700g oat milk
3tbsp cider vinegar
3tsp vanilla paste
300g sunflower oil (plus extra to grease)
Vegan chocolate ganache
500g Vegan double cream
500g dark chocolate (chopped)
For the chocolate drizzle
75g vegan dark chocolate
1.5tsp vegetable oil
Method
For the chocolate sponge
Preheat the oven to 160oC (Fan). Grease and line three deep 15cm cake tins with oil and baking paper. In a measuring jug add the oat milk, vanilla and the cider vinegar and let it sit for 5 mins. In a large mixing bowl add all the dry ingredients and mix well. Add the oat milk and vinegar mix, followed by the oil, and whisk well to create the cake batter. Divide the batter equally between the prepared cake tins and bake in the preheated oven for about 50-60mins or until a skewer inserted comes out clean. Once baked, take the sponges out of the oven, and let them cool in the cake tin for 10mins, before transferring them to a wire rack to cool completely.
For the vegan ganache
Warm the vegan double cream in the microwave or on the hob till it is about to boil. Add the chopped chocolate. Let it sit for 2-3mins then mix it well to get a silky-smooth ganache. Cover and let it cool until it is almost set. Once it is almost semi-set, whisk the ganache till it is smooth and spreadable.
Sandwich the cake and decorate
Sandwich all three layers of cooled sponges with the ganache. Coat the sides of the cake with more ganache and smooth using a cake scraper. Place in the fridge for an hour to set. As the cake is setting in the fridge, make the chocolate drizzle. Melt the chocolate in a microwave and mix the oil in thoroughly. Spoon it in a piping bag and keep it aside. Once the ganache is set. Pipe the drizzle down the sides of the cake. Decorate with rest of the ganache.
