For NZ’s favourite chocolate cake recipe.......
Preheat the oven to 180°C (reduce to 160 for fan forced). Grease and line a 23-25cm cake tin with baking paper.
Dissolve the coffee granules in water, then place all ingredients into a food processor and process until well combined and smooth.
Pour the mixture into the cake tin. Bake in the preheated oven for 1 hour 20 minutes to 1 hour 30 minutes, or until a cake tester inserted into the centre of the cake comes out clean.
Cool on a wire rack and when completely cold.
Place Chelsea Icing Sugar and cocoa powder in a medium bowl and stir to combine.
Add softened butter and pour some of the hot water over the top.
Mix together, adding more water as required to achieve a smooth, spreadable consistency.
Spread over the top of the cooled cake.
Note: This is a very runny mixture - don't be alarmed the first time you make it.
