Cake
- 1 ¾ cups all-purpose flour
- ¾ cup unsweetened cocoa powder
- 2 cups granulated sugar
- 2 tsp baking powder
- 1 ½ tsp baking soda
- 1 tsp salt
- 2 large eggs
- 1 cup whole milk
- ½ cup vegetable oil
- 2 tsp vanilla extract
- 1 cup hot coffee (or hot water)
Orange Custard Filling
- 1 cup freshly squeezed, strained orange juice
- 1 tbsp orange zest
- ½ cup granulated sugar
- 2 tbsp cornstarch
- 3 large egg yolks
- 2 tbsp unsalted butter
Chocolate Ganache
- 8 oz (225 g) dark chocolate, chopped
- 1 cup heavy cream
- 2 tbsp unsalted butter
Garnish
- Fresh orange slices or candied orange peel
- Preheat and Prepare Pans: Preheat your oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment paper to ensure the cakes release easily after baking.
- Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, unsweetened cocoa powder, granulated sugar, baking powder, baking soda, and salt until well combined.
- Add Wet Ingredients: Add the eggs, whole milk, vegetable oil, and vanilla extract to the dry ingredients. Mix thoroughly until the batter becomes smooth and homogeneous.
- Incorporate Hot Coffee: Slowly stir in the hot coffee (or hot water) to the batter. Note that the batter will be thin at this point, which is normal for this recipe.
- Bake the Cake Layers: Divide the batter evenly among the three prepared cake pans. Bake in the preheated oven for 25–30 minutes, or until a toothpick inserted into the center of the cakes comes out clean.
- Cool the Cakes: Remove the cakes from the oven and allow them to cool completely in their pans before assembling the cake.
- Prepare Orange Custard Filling: In a saucepan, whisk together the granulated sugar, cornstarch, and egg yolks until smooth. Gradually whisk in the freshly squeezed orange juice.
- Cook Custard: Cook the mixture over medium heat, stirring constantly to prevent lumps, until it thickens to a custard consistency.
- Finish Custard: Remove from heat, then stir in the orange zest and unsalted butter until fully incorporated. Let the custard cool completely before using.
- Make Chocolate Ganache: Heat the heavy cream until steaming but not boiling. Pour the hot cream over the chopped dark chocolate and let it sit for 2 minutes to melt the chocolate.
- Stir Ganache: Stir the chocolate and cream mixture gently until smooth and glossy. Add unsalted butter for a shiny finish, then let the ganache cool slightly so it thickens to a pourable consistency.
- Assemble Cake: Place one cake layer on your serving plate. Evenly spread a layer of the cooled orange custard filling over the cake.
- Add Second Layer: Place the second cake layer on top of the custard, spreading another layer of orange filling evenly.
- Top and Cover: Add the final cake layer on top. Pour the chocolate ganache over the entire cake, allowing it to drip down the sides naturally.
- Garnish and Serve: Decorate the cake with fresh orange slices or candied orange peel to enhance the flavor and presentation. Serve once the ganache has set slightly.
Notes
- Using hot coffee in the batter enhances the chocolate flavor and ensures a moist cake.
- Make sure the custard filling is completely cool before assembling to prevent it from melting the cake layers.
- For best results, assemble the cake a few hours before serving to allow flavors to meld.
- You can substitute the vegetable oil with melted coconut oil for a subtle flavor variation.
- Store leftover cake covered in the refrigerator for up to 3 days.
