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:

  1. Preheat your oven to 350°F (175°C). Grease and line the cake pans with parchment paper.
  2. In a large bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt until well combined.
  3. In another bowl, beat the eggs, milk, vegetable oil, vanilla extract, and orange zest until smooth.
  4. Pour the wet mixture into the dry ingredients, mix until just combined.
  5. Carefully stir in the boiling water until the batter is thin and well combined.
  6. Divide the batter evenly between the prepared pans. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
  7. Allow the cakes to cool for 10 minutes in the pans before transferring them to wire racks to cool completely.
  8. 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.
  9. Once cooled, layer the cakes, spreading ganache between layers and over the top. Garnish with additional orange zest if desired.
