Ingredients

Chocolate Orange Cake Batter

  • 210 grams (1 and ½ cup) all purpose flour, dip and sweep
  • 50 grams (½ cup) unsweetened cocoa powder, dutch processed
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 250 grams (1 and ¼ cup) granulated sugar
  • 2 tablespoons (18 grams) orange zest
  • 2 large eggs, room temperature
  • 150 grams (⅔ cup) unsalted butter, melted
  • 160 grams (⅔ cup) buttermilk*, room temperature
  • 120 grams (½ cup) fresh orange juice
  • 120 grams (½ cup) hot water
  • 1 recipe ganache, chocolate orange ganache
  • 1 recipe (optional) candied orange slices

Instructions

  • Preheat the oven to 350°F(177°C). Grease the bottom and sides of two 8-inch round cake pans and line the bottom with same-size parchment paper rounds and set aside the pans. 
  • Place the flour, cocoa powder, baking powder, baking soda and salt in a large bowl and stir with a whisk. Set aside.
  • Combine the orange zest and sugar in a medium bowl either rubbing with your fingers or stirring with a fork to bring the orange flavor out.
  • Add the eggs and stir with a whisk until combined for 20 seconds or so.
  • Add the melted butter, buttermilk and orange juice and stir with a whisk.
  • Pour the wet ingredients over the flour mixture and stir with a whisk.
  • Mix in the hot water.
  • Divide the mixture into 2 greased and parchment paper lined pans and bake for 24 minutes or until a toothpick that is inserted into the center comes out clean.
  • Prepare the ganache: While the cake is baking, you can make the ganache.  First let it cool at room temperature and then keep it in the fridge until it becomes a spreadable consistency.
  • Once cakes are baked, remove them from the oven and place on a wire rack to let them completely cool in the pan. After 20 minutes gently release the cake from the sides with a small spatula so you can remove them easily from the pan once needed. As they cool at room temperature, cover the pans with parchment paper and continue to cool in the fridge at least for an hour . This way you can level them (there may be domes in the middle part of the cake so you may need to level them to make them flat) and apply the frosting easily as they set.
  • If you want to decorate the cake with candied orange slices, you can make the recipe while waiting for the ganache and cake to set.

Assemble

  • Level the top of the cakes with a serrated knife. This way when you spread the filling between the layers, there will be no gaps between the layers as the tops will be flat.
  • Place the first layer on a cake plate and add a little less than half of the ganache over the first layer and spread it evenly with an icing spatula. Place the reverse side of the second cake layer on top and spread the ganache on top and cover the sides with a little ganache. Using the edge of the spatula make wave patterns. If using decorate with candied oranges.
  • Let the cake cool at least an hour before serving to let the cake set and cut proper sllices.

Notes

*You can make your homemade buttermilk by stirring 160 grams (⅔ cup) whole milk and 2 teaspoons of lemon juice.  You should leave it as is for 5-10 minutes.  Once curdled, it is ready to use.  Before using give it a stir.
How to store:  You should store the cake in the fridge as there is a ganache filling.
You can keep the tightly covered cake in the fridge for up to 5 days or in the freezer for up to a month.
Make Ahead:  Make the cake layers, let the cool completely at room temperature and once set, remove them from their pan and cover with plastic film and store in the fridge for up to 2 days. You can make the ganache 2 days in advance as well even prior to this time. You can also make candied orange slices up to 5 days in advance. When you are ready, you can assemble the cake. If you want to make this cake way ahead, you should freeze the cake layers and ganache. You should thaw overnight in the fridge before assembling. You can make the candied orange slices and keep in the fridge for up to 2 weeks.
