Method
Make the Syrup:
- Combine water and granulated sugar in a small saucepan.
- Heat until the sugar dissolves, then whisk in dark cocoa powder.
- Set aside to cool to room temperature.
2. Prepare the Cake Layers:
- Preheat oven to 350°F (175°C). Grease and line three 8-inch round pans with parchment paper.
- In a large bowl, whisk together flour, granulated sugar, dark cocoa powder, baking powder, baking soda, and salt.
- In another bowl, mix warm water, sour cream, vegetable oil, eggs, vanilla extract, and instant espresso (if using).
- Gradually add wet ingredients to dry ingredients, mixing until just combined.
- Divide batter evenly among prepared pans.
- Bake for 23-26 minutes or until a toothpick inserted in the center comes out clean.
- Cool in pans for 15 minutes, then transfer to wire racks to cool completely.
- Trim tops of cakes to level the layers.
3. Make the Buttercream Frosting:
- Beat unsalted butter in a large mixing bowl until smooth and creamy.
- Add dark cocoa powder, vanilla extract, and salt, mixing well.
- Gradually add powdered sugar, alternating with heavy cream, until frosting reaches desired consistency.
- Mix in melted dark chocolate chips for a rich, silky finish.
4. Assemble the Cake:
- Brush each cake layer with cooled syrup to enhance moisture and chocolate flavor.
- Spread a generous layer of buttercream between each cake layer.
- Cover the entire cake with buttercream, smoothing with an offset spatula.
5. Decorate the Cake:
- Press mini chocolate chips around the sides of the cake for added texture.
- Pipe decorative swirls or rosettes on top using remaining buttercream.
- Garnish with additional chocolate chips or shavings for a stunning presentation.
