You will need:
100g good-quality dark chocolate
1 large egg
10ml (2 tsp) oil
100g (¾ cup) flour
50g (¼ cup) granulated sugar
50g (¼ cup) castor sugar
25g (3 tbsp) cocoa powder
5ml (1 tsp) baking powder
50g good-quality dark chocolate
150ml (⅔ cup) cola
125ml (½ cup) brown sugar
125ml (½ cup) icing sugar, plus extra
5ml (1 tsp) cocoa powder
Preheat the oven to 160°C. Grease an 18cm cake pan.
For the cake, heat the butter and chocolate in a heatproof bowl over simmering water until melted.
Whisk the egg, oil and cola together in a separate bowl. Sift the dry ingredients into a mixing bowl, make a well in the centre and gently mix in the chocolate mixture. Stir in egg mixture, mixing thoroughly until the batter is smooth. Pour mixture into the prepared cake pan and bake for 35-45 minutes or until a skewer comes out clean when tested. Remove from oven and allow to cool.
For the ganache, combine the chocolate, cola, brown sugar, icing sugar and cocoa powder in a saucepan and heat gently until chocolate is melted. Bring to the boil, reduce heat and simmer until mixture has reduced and coats the back of a spoon. Pour ganache over cooled cake allowing it to run down the sides too. Dust top with sifted icing sugar and top with strawberries.
