1.Preheat oven to 150°C. Lightly grease and line the base and sides of 2 x 20cm round cake pans.
2.In a large saucepan, stir sugar, water, butter, chocolate, coffee and vanilla on low until smooth. Transfer to a large bowl. Cool for 30 minutes. Lightly whisk in eggs. Stir in combined sifted dry ingredients.
3.Divide mixture evenly between pans. Bake for 1 ½ hours until cooked when tested. Cool in pan for 10 minutes. Turn onto a wire rack to cool completely.
4.Meanwhile, to make milk chocolate ganache; in a small saucepan, heat cream on medium until almost boiling. Remove from heat. Add chocolate, stirring until smooth. Transfer to a glass bowl. Cool, covered, for 1 hour until spreadable.
5.Trim tops of cakes with a serrated knife until level. Half each cake horizontally.
6.Place one cake piece on a serving plate. Spread with 2 tablespoons ganache. Repeat with remaining cakes.
7.Spread remaining ganache roughly over top and sides of cake. Using a long palette knife, gently smooth edges, removing excess ganache, so you can just see the layers. Serve cake topped with raspberries and lightly dusted with icing sugar.
Naked and semi naked cakes, are pared down creations that allow the layers, colour and texture of the cake can shine through. Cake must be completely cool before attempting to halve or spread with ganache. If you prefer a smaller cake, simply halve the mixture and bake in one pan.
