Ingredients:
- 1 ¾ cups (220g) all-purpose flour
- ¾ cup (65g) unsweetened cocoa powder
- 2 cups (400g) granulated sugar
- 1 ½ teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt
- 2 large eggs
- 1 cup (240ml) whole milk
- ½ cup (120ml) vegetable oil
- 2 teaspoons vanilla extract
- Zest of 1 large orange
- 1 cup (240ml) boiling water
- 1 cup (240ml) heavy cream
- 8 ounces (225g) semi-sweet chocolate, chopped
- 2 tablespoons orange juice
- Additional orange zest for garnish (optional)
Instructions:
- Preheat your oven to 350°F (175°C). Grease and line the cake pans with parchment paper.
- In a large bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt until well combined.
- In another bowl, beat the eggs, milk, vegetable oil, vanilla extract, and orange zest until smooth.
- Pour the wet mixture into the dry ingredients, mix until just combined.
- Carefully stir in the boiling water until the batter is thin and well combined.
- Divide the batter evenly between the prepared pans. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
- Allow the cakes to cool for 10 minutes in the pans before transferring them to wire racks to cool completely.
- Heat heavy cream in a double boiler or microwave until just simmering. Pour over chopped chocolate and let sit for 5 minutes. Add orange juice and whisk until smooth.
- Once cooled, layer the cakes, spreading ganache between layers and over the top. Garnish with additional orange zest if desired.
