Ingredients
For the Cake:
- 2½ cups (300g) all-purpose flour
- 3½ tbsp cocoa powder
- 1¾ tsp baking soda
- 1¾ tsp baking powder
- 1¼ cups (225g) sugar
- 4 tbsp golden syrup or light corn syrup
- 4 extra-large eggs, beaten
- 1 cup (275ml) sunflower oil
- 1 cup (275ml) milk
For the Frosting:
- 1 lb + 2 oz (500g) dark chocolate, broken into pieces
- 1 cup (250g) unsalted butter
To Finish:
- 2½ oz (70g) Belgian white chocolate, coarsely grated

Instructions
Make the Cake
Start by preparing the moist and chocolatey base that will be the heart of this indulgent dessert.
Prep the Oven and Tins:
Preheat your oven to 350°F (175°C). Grease two 8-inch round cake tins and line them with parchment paper for easy removal.
Mix Dry Ingredients:
In a large bowl, sift together the flour, cocoa powder, baking soda, and baking powder. Stir in the sugar to combine.
Add Wet Ingredients:
In a separate bowl, whisk together the golden syrup, eggs, sunflower oil, and milk. Gradually pour this into the dry ingredients, mixing until you have a smooth batter.
Bake the Sponges:
Divide the batter evenly between the prepared tins. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool in the tins for 10 minutes before transferring to a wire rack to cool completely.
Make the Frosting
Create a silky, rich frosting that will take this cake to the next level of decadence.
Melt the Chocolate and Butter:
In a heatproof bowl set over a pot of simmering water, melt the dark chocolate and butter together, stirring occasionally until smooth. Let the frosting cool slightly so it thickens enough to spread.
Assemble the Cake
Bring it all together with layers of cake, frosting, and a stunning chocolate topping.
Layer and Frost:
Place one cake layer on a serving plate and spread a generous amount of frosting on top. Add the second layer and cover the entire cake with the remaining frosting, smoothing it with a spatula for a polished look.
Decorate:
Sprinkle the grated Belgian white and dark chocolate over the top of the cake for a striking finish.
