The trick to cooking mud cakes is to cook them low and slow. If they’re browning too much, simply pop a loose piece of foil over the top of the cake tin and continue cooking.

You can cut this cake into two layers and add some frosting in the middle. And of course, you can change things up and make a raspberry buttercream or a chocolate frosting instead.

Ingredients

  • 200 g white chocolate, broken into pieces
  • 350 g unsalted butter
  • 590 g caster sugar
  • 375 ml (1 1/2 cups) milk
  • 300 g (2 cups) plain flour
  • 100 g (2/3 cup) self-raising flour
  • 2 tsp vanilla extract
  • 3 eggs
  • 200 g white chocolate, broken into chunks
  • 250 g unsalted butter
  • 250 g icing sugar

Instructions

  1. Preheat oven to 140 degrees celsius. Grease and line the base and sides of a 23cm round cake tin and set aside. 

  2. Place the white chocolate, butter, caster sugar and milk into a microwave-safe bowl. Melt on 50% power, 3-4 minutes (stirring every minute) until melted and smooth. Set aside to cool. 

  3. Whisk through the plain flour, self-raising flour, eggs and vanilla extract. 

  4. Pour into the prepared tin and bake for approximately 1 hour and 45 minutes or until a skewer inserted into the middle comes out clean (see notes). 

  5. Allow the cake to cool completely in the tin before removing to a serving plate. 

  6. Once the cake has completely cooled, make the buttercream by melting the white chocolate (on 50% power, 2-3 minutes in the microwave - stirring every 30 seconds). Allow the chocolate to cool to room temperature.

  7. Using hand-held beaters, beat the room temperature butter until pale, smooth and creamy. Add the icing sugar (1 tbs) at a time and continue to beat until completely combined. 

  8. Very slowly beat through the cooled (room temperature) white chocolate until smooth, creamy and spreadable (see notes). 

  9. Spread the buttercream over the sides and top of the mud cake. 

Recipe Notes

If you notice that the mud cake is browning too much while cooking, loosely place a sheet of foil over the top and continue cooking. 

Please note that your melted white chocolate needs to be cooled to room temperature before adding to the frosting (to ensure a smooth result). 

If you find that your frosting is too thick to spread, simply add a small amount of milk and beat through.
