Ingredients
  

  • 200 gm butter unsalted
  • 200 gm caster sugar 1 cup
  • 320 gm plain flour 2 cups
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 150 gm white chocolate melted
  • 250 ml buttermilk 1 cup
  • 3 large eggs 70 gm
  • vanilla

Icing

  • 150 gm butter unsalted
  • 260 gm icing sugar 2 cups
  • 150 white chocolate melted set aside
  • 5 ml vanilla

Decorating

  • 50 gm white chocolate block
  • 25 gm pepita seeds or any toasted nuts

Instructions
 

  • Oven 170 C/ 320 F or 160 C / 320F fan forced. Line and grease a rectangular 17x 24 cm or 9x7 in square tin or see variations in notes (a smaller tin for a deeper cake cook times may vary)
  • Mix the flour with the baking powder and baking soda in a bowl with a whisk or sieve
  • Melt the butter over a double boiler or very very gently in the microwave at small intervals. Set aside to use when just warm
  • Beat the butter and sugar for the cake until very light and fluffy.
  • Add the eggs one a time combining completely. Then add 1/2 the flour and 1/2 buttermilk. Mix lightly. Then add the remaining buttermilk and flour mixing till only JUST combined.
  • Now turn off the mixer and add all of the chocolate and beat into the batter till incorporated. Approximately 1/2 a minute
  • Spoon into the prepared tin and bake for approx 45- 50 minutes. test with a skewer. If the skewer is removed with batter cook a further 10 minutes and test again. The skewer will come out clean when cooked. This cake can take a usually little over an hour, you can cover it with foil at this stage to stop it getting more colour if you wish.

The Icing

  • Beat the softened butter with the icing sugar (powdered sugar) till light. This is very important as it will make your frosting light and fluffy
  • Scrape down the sides frequently when creaming
  • Stop the mixer and add all of the chocolate. Beat well to combine and add more air.
  • Spread the frosting onto a cooled cake. It can be decorated with chocolate shavings. make these by "peeling" the chocolate with a vegetable peeler over a bowl. Sprinkle the cake with the chocolate and toasted seeds or nuts

Notes

This cake is better baked at a lower temperture so the outside doesn't caramelize too much. For fan forced ovens keep the temperature at 160C or 320 F.
I have an oven that is not fan forced and so I set it to 170 C/ 340F
Use a piece of foil to cover the cake towards the end of the cooking if you would like to stop it colouring too much
You can add a little lemon zest to both the cake and the frosting if you like!
