  • 1 tsp Bicarbonate of soda
  • 1 tbsp Apple cider vinegar Optional, see notes*

For the white chocolate buttercream

  • 425 grams Vegan butter
  • 500 grams Icing sugar

  • 2 tsp Vanilla extract

Instructions
 

To make the vanilla sponges

  • Pre-heat the oven to 180°C conventional (160°C fan)
  • Line the two cake tins with greaseproof paper and set aside
  • In a mixing bowl, beat together the sugar and butter until smooth and creamy
  • Using a second bowl, split the egg whites into the new bowl (setting it aside for later) and the egg yolks into the bowl containing the sugar and butter mixture
  • Beat in the egg yolks into the sugar and butter mixture
  • Using a sieve, sift in the flour, xanthan gum, bicarbonate of soda, baking powder to the bowl containing the eggs, butter and sugar and mix together
  • Optional: mix in the apple cider vinegar to the plant-based milk to create a vegan 'buttermilk'
  • Little by little, add in the plant-based milk/buttermilk and then whisk until everything is combined well
  • Get the bowl containing the egg whites and whisk until stiff peaks form (~8-10 minutes)
  • Gently fold the egg whites into the rest of the cake mixture using a spatula, ensuring not to mix too much which will cause the whisked in air to escape
  • Evenly pour the cake batter between the two tins and level out with the spatula if needed
  • Bake for 35-40 minutes until golden and slightly risen
  • Remove from the oven after baking and leave in the tins to cool (~30 minutes)
  • Remove from the tins and place on a wire rack for a further 30 minutes to cool completely
  • Use a serrated knife to level out the top of the cakes, cutting off any 'dome shaped top' that may have formed during baking

To decorate the cakes

  • When you are ready to decorate, beat together the butter, vanilla extract and icing sugar in another bowl (this will take about 10 minutes to get a smooth and silky finish -using a machine if you wish)
  • Using a microwave or Bain-Marie, gently melt the white chocolate until liquid
  • Fold the melted chocolate into the buttercream mixture, ensuring it is evenly distributed
  • Place the bottom sponge onto an even surface (or cake board) to decorate
  • Using a piping bag and nozzle, spoon a small amount of buttercream into the bag and evenly pipe buttercream onto the top of the first cake layer in a spiral motion, starting from the outside and going in
  • Use an icing spatula to even out the layer of icing so it is fully covered
  • Place the 2nd cake tier onto the base and create a 'sandwich' with the icing
  • Take the icing spatula and coat the cake in 1/3 of the icing to create a crumb coat
  • Place the cake in the fridge for ~15 minutes for the coat to harden
  • Use the remaining icing to coat the rest of the cake evenly, using the icing smoother to create an even finish
  • Slice into 10-12 portions, tuck in and enjoy!

Notes

*The apple cider vinegar is an optional addition to the milk, but it gives an overall fluffier cake sponge
  • Not suitable for home freezing
  • Store in an air-tight container in the fridge for up to 7 days or at room temperature for 3-4 days
