For the Cake:
- 1 and 3/4 cups (220g) all-purpose flour
- 3/4 cup (65g) unsweetened dark cocoa powder
- 2 cups (400g) granulated sugar
- 1 and 1/2 tsp baking powder
- 1 and 1/2 tsp baking soda
- 1 tsp salt
- 2 large eggs
- 1 cup (240ml) whole milk or buttermilk
- 1/2 cup (120ml) vegetable oil
- 2 tsp vanilla extract
- 1 cup (240ml) hot strong brewed coffee, freshly made
For the Mocha Frosting:
- 1 cup (230g) unsalted butter, softened
- 2 and 1/2 cups (300g) powdered sugar
- 3/4 cup (65g) unsweetened dark cocoa powder
- 2 tbsp instant coffee granules dissolved in 2 tbsp hot water or strong espresso
- 1/4 cup (60ml) heavy cream or milk
- 1 tsp vanilla extract
- A pinch of salt
- Preheat and Prepare Pans: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line them with parchment paper to prevent sticking.
- Mix Dry Ingredients: In a large bowl, sift together the all-purpose flour, unsweetened dark cocoa powder, granulated sugar, baking powder, baking soda, and salt to ensure even distribution and a smooth batter.
- Add Wet Ingredients: Add the eggs, whole milk (or buttermilk), vegetable oil, and vanilla extract to the dry mixture. Beat on medium speed for 2 minutes until the batter is smooth and well combined.
- Incorporate Coffee: Stir in the hot strong brewed coffee carefully. The batter will be thin, which is expected and ensures a moist cake.
- Divide Batter: Evenly pour the batter into the two prepared cake pans, smoothing the tops with a spatula.
- Bake: Bake in the preheated oven for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean, indicating the cakes are fully baked.
- Cool Cakes: Let the cakes cool in their pans for 10 minutes, then transfer them onto wire racks to cool completely before frosting.
- Prepare Mocha Frosting: Beat the softened unsalted butter in a bowl until creamy, about 2 minutes. Gradually add the cocoa powder, powdered sugar, and a pinch of salt, mixing slowly at first then increasing speed for a fluffy texture.
- Add Coffee and Cream: Stir in the dissolved instant coffee, vanilla extract, and heavy cream (or milk). Beat until the frosting is smooth and fluffy, around 2 to 3 minutes. Add more cream if a smoother consistency is desired.
- Assemble the Cake: Level the cooled cakes if needed to create flat tops. Place one cake layer on your serving plate and spread a generous layer of mocha frosting on top.
- Finish Frosting: Place the second cake layer over the first and frost the top and sides evenly. Optional decorations include chocolate shavings, coffee beans, or a light dusting of cocoa powder for an elegant finish.
Notes
- Use freshly brewed hot coffee for the best flavor infusion in the cake.
- If you prefer, substitute buttermilk for whole milk for a slightly tangier and tender crumb.
- The batter will be thin; this is normal and ensures moistness.
- Adjust the amount of heavy cream in the frosting to reach your desired consistency.
- For a dairy-free version, substitute butter and milk with plant-based alternatives.
- Store the finished cake covered in the refrigerator for up to 3 days.
- Let the cake come to room temperature before serving for optimal flavor and texture.
