Ingredients

Chocolate Cake
  • 5 eggs
  • 2 cups (500ml) white sugar
  • 1 cup (250ml) vegetable oil
  • 2 cups (500ml) all purpose cake flour
  • 20 ml baking powder
  • 1 tsp salt
  • 10 ml vanilla essence
  • 3/4 cup (187.5ml) cocoa powder
  • 1 cup boiling water
  • 1 tsp coffee granules
Whipped Milk Chocolate and Coffee Ganache
  • 1 cup (250ml) fresh cream
  • 300g milk chocolate
  • 1 tsp coffee granules

Instructions

Chocolate Cake

  • Whisk eggs and sugar until light and fluffy.
  • Add in vanilla essence and vegetable oil.
  • Fold in the sifted dry ingredients (flour, baking powder and salt).
  • Dissolve 3/4 cup cocoa powder and 1 teaspoon of coffee granules in one cup of boiling water. Add this mixture into the cake batter. Fold in gently.
  • Pour into a well-greased baking tray and bake at 170°C for about 45 minutes. Baking times may vary depending on your oven, so start monitoring after the 35-40 minute mark. The cake should bake evenly and appear level rather than domed when done.

Whipped Milk Chocolate and Coffee Ganache

  • Place the cream, chopped milk chocolate, and coffee granules in a saucepan over very low heat.
  • Stir constantly until the chocolate and coffee fully melt and the mixture is smooth and glossy. The cream should be hot and steaming, but never boiling.
  • As soon as everything is smooth, take the saucepan off the heat.
  • Transfer the ganache to a bowl. Cover and refrigerate for 3–4 hours, or until thick but still soft.
  • Using an electric mixer, whip on medium speed until light, fluffy, and spreadable. Stop as soon as it holds soft peaks. Do not overwhip and this will split the cream.
