Ingredients
For the Cake:
- 1½ cups (200g) all-purpose flour
- 1 cup (225g) buttery spread, chilled
- ⅓ cup (30g) cocoa powder
- 1 cup (200g) granulated sugar
- 2½ tsps baking powder
- ¾ tsp salt
- 4 extra-large eggs
- Zest of 2 oranges, finely grated
For the Frosting:
- 9½ ounces (270g) orange chocolate, broken into pieces
- ⅔ cup (150g) salted butter, softened
- 2 cups (250g) confectioners’ sugar, sifted
- 1.5 ounces (50g) orange chocolate, roughly chopped
Instructions
Make the Cake:
Prepare the Oven and Tins:
Preheat your oven to 350°F (175°C). Grease and line two 8-inch round cake tins with parchment paper.
Mix the Dry Ingredients:
In a large mixing bowl, sift together the all-purpose flour, cocoa powder, baking powder, and salt. Stir in the granulated sugar until combined.
Incorporate the Wet Ingredients:
Add the chilled buttery spread, eggs, and orange zest to the dry mixture. Use an electric mixer to blend everything until smooth and creamy.
Bake the Cakes:
Divide the batter evenly between the prepared tins, smoothing the tops with a spatula. Bake for 25–30 minutes, or until a skewer inserted in the center comes out clean. Allow the cakes to cool in the tins for 10 minutes, then transfer to a wire rack to cool completely.
Make the Frosting:
Melt the Orange Chocolate:
Place the orange chocolate pieces in a heatproof bowl and melt them over a pot of simmering water. Stir occasionally until smooth, then let it cool slightly.
Prepare the Buttercream:
In a large bowl, beat the softened butter until light and fluffy. Gradually add the confectioners’ sugar and continue beating until smooth. Mix in the melted chocolate until fully incorporated.
Assemble the Cake:
Layer and Frost:
Place one cake layer on a serving plate and spread a generous layer of frosting over the top. Add the second cake layer and cover the top and sides with the remaining frosting.
Decorate:
Sprinkle the roughly chopped orange chocolate over the top for a decorative and flavorful finishing touch.
