Instructions

1. Chocolate cake
   Preheat the oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. Grease two 8-inch round cake pans with oil spray and line with baking or parchment paper.
2. In a large mixing bowl, add flour, cocoa powder, baking soda, salt and sugars and stir briefly.
3. In a separate mixing bowl, add water, oil and vanilla. Add water mixture to dry ingredients and stir to combine. Pour into prepared cake tins and bake for 25-30 minutes or until a skewer inserted in the middle comes out clean.
4. Leave cakes to cool in cake tin before carefully transferring to a wire rack to cool completely.
5. Chocolate frosting
   Place butter in a large mixing bowl and beat with an electric mixer on medium speed until smooth and creamy.
6. Add sugar, cocoa and 2 tablespoons of milk and then beat on medium speed again for a further minute or two until frosting is smooth and creamy. Scrape down the sides as needed.
7. If the frosting is too thick, add an extra tablespoon of milk. Use a small spatula to frost sides, middle and top of cakes.
