Black forest cakes are a tried and true favourite for a reason – especially when cherries are in season and at their most flavoursome. This is another cake using the Milk Bar method of cutting out rounds from a large rectangular sponge cake, ensuring you get perfectly even layers every time.
While I made this into a 2-layer cake this time as it was a gift for a couple in quarantine who didn’t need a giant cake, the recipe actually makes a 3-layer cake.
Ingredients (serves 12-14)
Equipment
9 x 13 inch “quarter sheet pan”*
A 6 inch cake ring*
6 inch wide acetate roll
Sticky tape
Chocolate Ganache
120g dark chocolate melts
90ml cream
Cake
115g butter, room temperature
300g caster sugar
3 large eggs
120ml buttermilk
60ml canola oil
2 tablespoons chocolate ganache
2 teaspoons vanilla extract
1 teaspoon instant coffee
130g plain flour
15g cornflour
70g cocoa powder
1½ teaspoons baking powder
Cherry Jam
225g fresh or frozen cherries (pitted and chopped finely)
25g caster sugar
1 tablespoon cornflour
Buttercream
115g butter, roughly chopped, room temperature
2 teaspoons vanilla extract
2 cups icing sugar
1 tablespoons full-fat greek yoghurt, room temperature
½-1 tablespoon full-cream milk, room temperature
Cherry Milk Soak
40ml full-cream milk
25ml kirsch (cherry liqueur) or cherry juice
10-12 large fresh cherries, to decorate
Method
Chocolate Ganache
Add the dark chocolate and cream to a small saucepan and stir over a low heat until the chocolate is nearly melted. Remove from the heat and continue stirring until the chocolate is fully melted and smooth. Set aside (at room temperature).
Cake
Preheat oven to 180°C (160°C fan-forced). Spray the base and sides of a quarter sheet pan with cooking oil and line the base with baking paper.
Cream the butter and sugar together in a stand mixer, or a large bowl if using a hand mixer, on a medium speed until light and fluffy. Add the eggs and beat on high until combined.
Add the buttermilk, oil, 2 tablespoons of your pre-prepared chocolate ganache, vanilla and coffee into a small bowl and stir until the coffee has dissolved. Add this chocolate mixture into the the butter mix and beat on high for a few minutes, scraping down the bowl as required.
Sift the flour, cornflour, cocoa powder and baking powder into the batter. Beat on low until the mixture has just combined, and then pour the batter into the lined cake tin. Smooth out flat and tap the tray gently against the bench a few times to get out any air bubbles.
Bake for 25-35 minutes, or until a skewer inserted into the middle comes out clean. Leave to cool in the tin for about 15 minutes and then remove from the tin and place on a wire rack to cool completely.
Cherry Jam
Place the cherries, caster sugar and cornflour into a saucepan over a medium heat. Stirring constantly, bring the mixture to the boil. Reduce the heat slightly and continue to stir until thickened.
Buttercream
Beat butter in a large mixing bowl with an electric mixer on medium speed for 1-2 minutes until butter is pale and creamy.
Add vanilla and 1 cup of icing sugar. Beat on a low speed to combine, then turn up to medium and mix for 30 seconds. Add the remaining icing sugar along with the greek yoghurt. Beat on medium speed until light and fluffy. If too stiff, add milk. If too wet, add extra icing sugar. It should be fluffy and spreadable.
Cherry Milk Soak
Add milk and kirsch to a small bowl and whisk to combine.
Assembling the Cake
Place your cake on a large chopping/bread board. Using the picture below as a guide, use a 6 inch metal cake cutter to cut out 2 rounds of cake and then two half pieces.

Place the 6 inch cake ring onto a plate or cake stand. Line the inside of the cake ring with a ‘collar’ of acetate, taping the edges together to join.
Place the two half pieces of cake at the bottom and press down firmly. If there are any gaps, use extra cake scraps to fill in the holes and press down very firmly to make one even layer. Carefully remove the cake ring (but leave the acetate).
Spoon 2 tablespoons of the milk soak over the cake layer. Allow to soak for about a minute. Spoon approximately one third of the chocolate ganache onto the cake layer, and spread evenly, ensuring the ganache gets right to the edges of the cake. Spoon half of the cherry filling on top of the ganache and spread out evenly to the edges of the cake. Add a few tablespoons of buttercream on top and smooth with a spatula to ensure the layer is (roughly) even.
Repeat this process for the second layer: cake, cherry milk soak, chocolate ganache, the remaining cherry jam and a thick layer of buttercream. If you need to, attach another round of acetate on top of your current cake collar (using tape to join the two collars) to ensure it is tall enough that all cake is supported.
Add the final layer of cake, spoon with the remaining milk soak and then top with the remaining chocolate ganache. Decorate with a ring of cherries and place in the fridge to set for a few hours. While the cake sets, add any remaining buttercream to the cake offcuts and enjoy as a snack!
Remove the cake from the fridge and gently peel away the acetate strip/s just before serving. Enjoy!
