Ingredients

For the red velvet cake layer

  • 140 g/1 cup all purpose flour
  • 1 tbsp cocoa powder
  • 120 g/1/2 cup buttermilk
  • 1-2 g/1/4 tsp paste red food colouring not gel
  • 60 g/1/4 cup unsalted butter softened
  • 160 g/3/4 cup caster/superfine sugar
  • ¼ tsp salt
  • 1 ½ tsp vanilla
  • 1 egg large
  • 1 tsp white vinegar
  • ½ tsp baking soda

For the truffle layer

  • 300 g/1 ¼ cup double cream/heavy cream highest fat content you can find (I used 48% fat double cream)
  • 350 g/ 12 oz white chocolate chopped, not chocolate chips (measured by weight)
  • 250 g/9 oz mascarpone full fat only
  • 1-2 drops adjust the amount depending on the strength pink colouring
  • organic rose petals for decoration
  • red velvet cake crumbs for decoration

Instructions

For the red velvet cake layer

  • Preheat the oven to 180C/350F. Prepare an 8 inch springform pan by greasing it with butter, then cut out a circle to fit the pan out of parchment paper and line the bottom of the pan with it.
  • In a medium bowl sift together flour and cocoa powder.
  • In the bowl of a stand mixer cream butter and sugar until pale and fluffy. Mix egg and vanilla in a small bowl, then gradually add the mixture to the butter and sugar with the motor of the stand mixer still running. If the mixture separates, add a tablespoon from the flour and cocoa mix.
  • Mix the red food colouring with 2 tbsp of buttermilk until completely dissolved, then add it to the rest of the buttermilk and mix well.
  • Starting and ending with the flour mixture, alternate adding the flour and cocoa and buttermilk to the butter, sugar and egg mix. Stop the mixer once in a while to scrape the bottom with a spatula, continue mixing until your cake batter looks like a light, evenly blended frosting.
  • Mix the vinegar and baking soda together in a small bowl, it should froth up, then add it to the cake and mix well.
  • Pour the batter into the prepared springform cake pan and bake for 25 minutes or until a toothpick inserted in a cake comes out clean. Cool in the pan for 10 minutes, then remove from the pan and cool on a wire rack completely.
  • Cut off the domed top of the cake with a sharp knife if the cake didn't come out perfectly flat and reserve it for making crumbs for decoration.

For the truffle layer

  • Bring the cream in a saucepan to a boil, then immediate pour over chopped white chocolate, let it sit for 1 minute, then stir until the chocolate is completely melted into the cream, add the food colouring and cool until room temperature.
  • In a medium bowl combine mascarpone and chocolate cream mixture, whip with a hand mixer until the truffle layer is thick and holds its shape when mounted on a spoon. (Watch video for the right consistency).

To assemble the cake

  • Line the sides of the same springform pan with parchment paper all around and put the cooled red velvet cake back in the pan. (If the cake slightly shrunk during baking and doesn't fill the cake pan entirely, insert a folded layer of paper tower between the walls of the pan and the parchment paper lining to ensure the cake fits in snugly. This will prevent the truffle layer from seeping through.)
  • Pour the truffle layer over the cake layer and smooth the top with a spatula. Cover the pan with a cling wrap and refrigerate for at least 3 hours.
  • After the truffle layer is set, remove the sides of the springform pan and pull the parchment paper off in one smooth movement. Smooth the sides of the truffle with an offset spatula for a clean look.
  • Decorate the cake with organic rose petals and red velvet crumbs if desired.
