The thick, creamy chocolate frosting is the perfect finishing touch, creating a decadent contrast with the cake’s airy crumb. Plus, it’s easy to make ahead — just bake, frost, and let the flavors develop overnight, making it a stress-free dessert for entertaining.

Once you try this cake, you’ll agree — it truly is the world’s best chocolate cake.
1 3/4 cups (220g) all-purpose flour
3/4 cup (65g) unsweetened Dutch-process cocoa powder
2 cups (400g) granulated sugar
1 1/2 tsp baking powder
1 1/2 tsp baking soda
1 tsp salt
2 large eggs
1 cup (240ml) buttermilk, room temperature
1/2 cup (120ml) vegetable oil
2 tsp pure vanilla extract
1 cup (240ml) hot coffee (or hot water with 1 tsp espresso powder)
1 lb (454g) unsalted butter, softened
1 cup (85g) Dutch-process cocoa powder
6 cups (720g) powdered sugar, sifted
1/4 cup (60ml) whole milk, plus 1-2 tbsp more only if needed
2 tsp vanilla extract
1/2 tsp fine salt
Preheat oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper.
In a large mixing bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt.
Add eggs, buttermilk, oil, and vanilla. Mix until smooth. Slowly add hot coffee and stir until fully combined — the batter will be thin.
Divide the batter evenly between the two pans. Bake for 30–35 minutes, or until a toothpick inserted comes out clean. Let cool in pans for 10 minutes, then transfer to a wire rack to cool completely.
Beat the butter until creamy. Add cocoa powder and beat until smooth. Gradually add powdered sugar and milk, beating until fluffy (about 2-3 minutes). Add a tablespoon of milk at a time until it reaches the desired consistency for spreading or piping. Stir in vanilla and a pinch of salt.
Place one cake layer on a serving plate. Spread a generous layer of frosting on top. Add the second layer and frost the top and sides. Smooth or swirl the frosting with an offset spatula.
This frosting is enough to fill and frost a 2- or 3-layer cake generously and pipe borders or rosettes.
For ultra-smooth texture, use room temperature butter and sift the cocoa and powdered sugar.
Chill slightly before piping if the frosting becomes too soft in warm conditions.
To give the edges a neat, sharp finish:
The 1M tip creates a soft, rounded rosette with beautiful detail, making your cake look professional and elegant.
If you want an extra crisp edge around the base, use a piping tip with a straight edge (like a #47 leaf tip) for a clean, professional look.
