Preheat oven to 180 degrees C. Grease and flour a 23x33cm cake tin.
In a large bowl, combine the flour, sugar, cocoa, baking soda, baking powder and salt. Make a well in the centre and pour in the eggs, coffee, milk, oil and vinegar. Mix until smooth: the batter will be thin.
Pour into prepared tin and bake for 35-40 minutes, or until a skewer inserted into the centre of the cake comes out clean. Allow to cool in the tin before slicing and serving.

Ok folks, this cake will put you in chocolate heaven. Have tried many recipes from this site and this one wins by a landslide. To be objective, I made this to the T the first time. It was fantastic. Moist, dark, rich. But after that, I've been using buttermilk in place of regular milk and used cake flour instead of plain flour (same amount) and the cake was super moist. I've learned when it comes to baking, using buttermilk where a recipe calls for milk makes everything more moist and fluffy. If Cake Flour is available, use. Be sure to add 2 extra tablespoons of cake flour for every cup of plain flour. The cake flour made it extra light and tender. No need for vinegar if using buttermilk. The 'sour' in buttermilk reacts with the leavening agents - baking powder/soda - which makes the cake rise and moist. I've also increased cocoa to 1 full cup & added 2 extra tablespoon sugar when I do, for a devils food style cake. And forget all the 'multi-bowl cake recipes'. This is so easy in prep and clean-up. Too good to be true, but it is. I usually bake mine in a 25cm bundt (cooking time appx. 38-40 min.) or two 22cm cake tins (25 min.). When making a layer cake, try frosting it with German Chocolate Frosting II (from this site) for ultimate decadence. You will get raves for this - even you first time bakers can't get this wrong. Update - Drizzle this with Chocolate Ganache - superb. - 29 Sep 2008
This is such a simple recipe and so delicious. The first time I made it I didn't have quite enough cocoa, so I tossed in a teaspoon of chocolate spread And also tossed in some rainbow choc bits, which added some colour. Turned out wonderfully. - 12 Apr 2011
