walnut coffee layer cake

This delicious walnut coffee layer cake is incredibly moist and filled with a luxurious mascarpone coffee cream, then wrapped in a silky coffee infused icing and sprinkled with walnuts. Perfect with a cuppa for afternoon tea.

Tasting notes: CSR Dark Muscovado Sugar has a sweet treacle aroma which enhances the coffee flavours in this moist cake. CSR Raw Caster Sugar, with its softer caramel flavour, adds depth to the sweet complex flavours.

  • 225g White Wings self-raising flour

for the mascarpone coffee filling

  • 2 tsp coffee granules

  • 1 tbs CSR Pure Icing Sugar
  • ½ tsp vanilla extract

for the icing

  • 1 tsp coffee granules

  1. Preheat oven to 180°C and grease and line the bottom of a 20cm round, loose bottom, cake tin.
  2. Dissolve one tablespoon of coffee granules in 1 tbs of boiling water.
  3. In a large bowl, combine flour, baking powder, almond meal, chopped walnuts, salt, CSR Muscovado Sugar and CSR Raw Caster Sugar.
  4. Make a well in the middle of the dry ingredients, add the eggs, yoghurt, oil (use walnut oil if you can, as it adds walnut flavour) and coffee mix, folding lightly together with a large metal spoon until smooth.
  5. Transfer the batter to the lined cake tin. Smooth the top slightly, cover with baking paper and bake for 40-45 mins or until a metal skewer comes out clean when inserted in the centre of the cake.
  6. Cool the cake for a short while, then turn it out onto a cake rack and remove the paper. Cool completely.
