The ultimate chocolate cake - moist, rich and not too sweet. Covered in luscious ganache. Quick to make and gone too soon. The ganache can be made while the cakes are baking. It will need to chill slightly before using (and this can be done while the cakes are cooling).Before You StartGet your eggs and buttermilk out of the fridge.

Instructions
Cake
Preheat Oven – to 170°C (fan-forced)
Coffee – prepare your coffee your preferred way and allow to cool.
240 ml freshly brewed coffee
Prepare Pans – generously butter the cake pans (using your fingers is the easiest way to do this). Line the base of the pans with baking paper and line the sides with a thin layer of cocoa powder. Tip in about a tablespoon of cocoa powder and, holding over the sink. swirl around to coat the sides. Tap the pan and shake excess cocoa powder into the second tin. Repeat, tipping the excess away.
butter
½ tablespoon cocoa powder
Dry Ingredients - sift the flour, sugar, cocoa, baking soda, baking powder and salt into a bowl big enough to take all the ingredients.
210 g plain/all purpose flour
350 g caster sugar
75 g cocoa powder
2 teaspoons baking soda
teaspoon baking powder
6 g salt
Wet Ingredients – combine the oil, eggs, vanilla and buttermilk in a bowl and whisk (by hand is fine). Add the cooled coffee liquid.
120 g vegetable oil
2 eggs
240 g buttermilk
Teaspoon pure vanilla extract/paste
Combine Wet & Dry – tip the wet ingredients over the dry and use a silicone spatula to combine. Use a combination of figure of 8 movements and scraping the bottom and sides of the bowl. Some lumps are fine.
Divide Batter – pour the batter evenly between the two cake pans. It will be very fluid. Gently knock out any bubbles by lifting then gently banging the tins back down on a work surface. Transfer the pans to the oven on the same rack.
Bake – for around 35 minutes, rotating the tins halfway through. A cake tester/toothpick inserted in the centre of the cake will come out slightly wet with moist crumbs, but not covered in clumps of wet batter. Return to the oven and retest after another five minutes if still undercooked in the centre. The cakes will look a bit sunken; this is fine. You won't be able to rely on sight; the cakes are dark-coloured to start with.
Cool- in the pans for at least 30 minutes. The cakes may sink a little further and they’ll shrink away from the sides of the pan. Run a butter knife around the outside and gently turn out onto a cooling rack to cool completely. Don’t put your hand on the top of the cake when doing this, the cake is very soft and may tear. Peel the baking paper off very carefully, especially if it went up the sides slightly.
Ganache
Chocolate & Cream – roughly chop the chocolate. Gently heat the cream over medium heat on the stovetop until steaming hot (but not boiling). You can heat in the microwave if you prefer. Add the chocolate, vanilla and salt. Leave to sit for a couple of minutes before stirring until fully melted. Stir occasionally until the chocolate is fully melted.
teaspoon pure vanilla extract/paste
170 g chocolate
230 g double/whipping/thickened/heavy cream
Pinch salt
Coffee – in a small bowl, fully dissolve the coffee in 2 teaspoons boiling water.
5 g instant coffee granules
Icing Sugar- sift the icing sugar. Add it to the chocolate cream with the dissolved coffee. Mix until fully combined.
125 g pure icing sugar
Chill - – chill the ganache for at least 45 minutes before using to allow it to firm up. If you’re in a hurry, you can make and chill the ganache while the cakes are baking and cooling. If you're making the ganache in advance, allow it to sit at room temperature after chilling until it's spreadable consistency before using it on the cake.
Assemble Cake – place one of the cakes on the plate you want to serve it on. Dollop about a quarter of the ganache in the centre and use an offset spatula to spread it out evenly. Place the second cake on top. Dollop the rest of the ganache on the top and work it outwards and down the sides. You can leave it as smooth or rustic as you like.
Notes
LeftoversKeep out of the fridge in a cool area for up to 5 days. Cover with a cake keeper so that you don’t smudge the icing. If it’s warm where you are, you can put in the fridge, but allow portions to come to room temperature for the best texture. You may need to trim the cut edges slightly if they dry out.Make ahead/freezeThe unfrosted cake will freeze very well. Cover tightly to avoid freezer burn or the absorption of freezer smells. Allow it to thaw in the fridge overnight and frost fresh. You can make the frosting and cake up to three days ahead of serving. Keep them separate and well covered in the fridge until ready to use. Allow the frosting to soften at room temperature before using.
