Chocolate Cake With Whipped Chocolate Frosting
CHOCOLATE CAKE WITH WHIPPED CHOCOLATE FROSTING
1 ½ cups cocoa (150g)
1 ½ cups boiling water
500 g butter
4 ½ cups caster sugar (1kg)
2 teaspoons vanilla
8 eggs
4 cups self-raising flour
1 cup flour (150g)
1 teaspoon bicarbonate of soda
2 ½ cups buttermilk (625ml)
WHIPPED CHOCOLATE FROSTING
300 g dark chocolate, chopped
200 g milk chocolate, chopped
180 g butter, chopped
2 teaspoons oil
Preheat the oven to moderately slow (160°C/140°C fan-forced). Whisk cocoa and boiling water in a medium bowl until smooth; cool. Grease a deep 30cm square cake pan. Line the base and sides with two layers of baking paper, extending the paper 5cm above the edge of the pan. Beat the butter, sugar and vanilla in a large bowl with an electric mixer until light and fluffy. Add eggs one at a time, beating until just combined between additions. Transfer butter mixture to a very large bowl. Stir in combined sifted flours and soda, and the buttermilk in three batches until well combined. Stir in the cocoa mixture, mix well. Spread mixture into the prepared pan and bake in a moderately slow oven for 1½ hours or until cooked when tested. Cool cake in pan for 20 minutes before turning onto a wire rack to cool. Spread Whipped Chocolate Frosting mixture over the top and sides of the cooled cake.
WHIPPED CHOCOLATE FROSTING: Place both chocolates and butter in a medium heatproof bowl, stir over a pan of simmering water until chocolate and butter melts. Stir in the oil. Refrigerate chocolate mixture until thick. Beat chocolate mixture with an electric mixer for about 3 minutes.
