Thanks to guest blogger Harlo Bakes – Meet “The Bruce,” the ultimate chocolate cake that will leave you and your guests in awe. This decadent dessert features rich layers of chocolate cake, creamy American buttercream, and a luscious chocolate ganache. Perfect for any special occasion, or simply to satisfy your deepest chocolate cravings. Let’s get baking!
Preheat your oven to 180°C (350°F). Grease four 6-inch cake tins with butter and line them with baking paper.
Dissolve 2 tablespoons of instant coffee in a small amount of boiling water. Melt the butter in the microwave and mix it with the dissolved coffee. Allow this mixture to cool.
In a large bowl, combine 100g cocoa powder, 200g brown sugar, 210g granulated sugar, 1 tsp bicarbonate of soda, and a pinch of salt.
Stir in the cooled coffee and butter mixture, along with 6 large eggs and 1 tbsp vanilla extract. Mix until smooth.
Gradually add 300g of plain flour to the mixture and whisk until fully combined.
Divide the batter evenly between the four prepared cake tins. Bake for 20 minutes, or until a toothpick inserted into the centre comes out clean. Cool the cakes in the tins for 5 minutes before transferring them to a wire rack to cool completely.
Once the cakes are fully cooled, wrap each layer in cling film and place them in the fridge for at least 4 hours, or overnight.
In a large bowl, beat 375g of softened unsalted butter until fluffy.
Gradually add 375g icing sugar, 25g cocoa powder, and 2 tsp vanilla extract. Beat for about 5 minutes until the mixture is light and fluffy.
Add 1 tsp of full-fat milk and beat until fully incorporated.
In a microwave-safe bowl, combine 580g chopped dark chocolate, 250ml heavy cream, and 1 tsp glucose syrup.
Microwave at 30-second intervals, stirring each time, until the mixture is smooth. Allow the ganache to sit at room temperature until it thickens slightly. If needed, microwave at 10-second intervals until the ganache is spreadable.
Trim and flatten the top of each cake layer to ensure even stacking.
Spread a thin layer of chocolate buttercream on your serving plate. Place the first cake layer on top and spread a generous layer of buttercream over it. Repeat with the remaining layers.
Apply a thin layer of buttercream around the entire cake to seal in the crumbs. Chill the cake in the fridge for 1 hour.
Once chilled, spread the chocolate ganache all over the cake for a smooth, glossy finish.
Your majestic “The Bruce” Chocolate Cake is now ready to serve! Store any leftovers in an airtight container for up to 3 days.
