Chocolate fudge cake with malted buttercream

1. Preheat the oven to 160°C. Line two 20 cm (8 inch) round cake tins with baking paper.
2. Whisk the brown sugar, flour, cocoa, baking powder, bicarbonate of soda and salt to ensure there are no lumps. (You can also sift these together, but you know how I feel about unnecessary sifting!)
3. Dissolve the coffee in the boiling water in a jug, then add the oil, sour cream and eggs and whisk until thoroughly combined. Make a well in the centre of the dry ingredients and pour in the egg mixture. Fold until just combined, being careful not to overmix to ensure you end up with a perfectly tender cake.
5. Split the batter between the cake tins and bake for 50 minutes or until a skewer inserted into the centre of each cake comes out clean. Allow the cakes to cool for 15 minutes before turning them out onto a wire rack to cool completely.
6. To make the buttercream, first ensure the butter is not too soft – it needs to still be slightly firm, otherwise your buttercream will be really soft and hard to work with.
7. Using an electric mixer fitted with the paddle attachment, cream the butter and icing sugar for 3–4 minutes, scraping down the side of the bowl a couple of times to ensure the mixture is completely smooth.
8. Add the cooled melted chocolate, malted milk powder and vanilla and mix for another 2–3 minutes or until the buttercream is smooth and fluffy.
Cook's note: I like to fill and cover this cake with the malted buttercream and top it with chocolate shavings – it’s a real show stopper. Pair your choccy cake with any buttercream you love.
