Ingredients Checklist

Starting with high-quality ingredients is essential for an unforgettable chocolate cake. Here’s everything you need for a classic, triple-layer chocolate cake and two types of chocolate frostings. Options for substitutions and add-ins are included.

For the Chocolate Cake

• 2 cups (240g) all-purpose flour

• 1 3/4 cups (350g) granulated sugar

• 3/4 cup (85g) Dutch-process cocoa powder (or a blend of Dutch and black cocoa for extra depth)

• 2 teaspoons (8g) baking soda

• 3/4 teaspoon (3g) baking powder

• 1 teaspoon (6g) fine salt

• 1 cup (240ml) buttermilk, at room temperature (or whole milk + 1 tbsp vinegar, rested 5 minutes)

• 1 cup (240ml) very hot water or strongly brewed coffee (enhances chocolate flavor)

• 1/2 cup (109g) neutral oil (vegetable, canola, or avocado)

• 3 large eggs, at room temperature

• 1 teaspoon (4g) pure vanilla extract

• Optional: 1 tablespoon espresso powder (for deeper flavor)

For Classic Chocolate Ganache Frosting

• 1 cup (236ml) heavy cream

• 12 oz (340g) semisweet or bittersweet chocolate, chopped

• Pinch of fine salt

• 2 tablespoons unsalted butter, room temperature (for extra sheen)

For Silky Chocolate Buttercream

• 2 cups (452g) unsalted butter, slightly chilled

• 5 cups (625g) powdered sugar, sifted

• 3/4 cup (65g) Dutch-process cocoa powder

• 1 tablespoon (14g) pure vanilla extract

• 1/4 teaspoon salt

• 6–8 tablespoons (90–120ml) heavy cream or milk, as needed

Optional Fillings or Toppings

• 1 cup mini chocolate chips or chopped chocolate for layering

• Chocolate shavings, curls, or sprinkles for decoration

• Fresh berries or candied orange peel for garnish

• 1 cup toasted nuts (pecans, walnuts, or hazelnuts)

Step-by-Step Instructions

A reliable method is just as important as great ingredients. Follow these steps for consistently moist, tall, and rich chocolate cake layers.

1. Prep and Pan Preparation

• Preheat oven to 350°F (175°C).

• Line three 9-inch (23cm) round cake pans with parchment paper. Grease and flour sides or use baking spray.

2. Mix the Dry Ingredients

• In a large bowl, whisk together flour, cocoa powder, baking soda, baking powder, salt, and espresso powder if using. Sift for a lump-free batter.

3. Mix the Wet Ingredients

• In a separate bowl, combine the sugar, eggs, and oil. Whisk until smooth.

• Stir in buttermilk and vanilla extract.

4. Combine and Add Hot Water

• Pour wet ingredients into the dry mixture and whisk gently until nearly combined.

• Gradually add hot water or coffee, whisking until the batter is smooth and pourable.

5. Bake the Cake Layers

• Divide the batter evenly between the prepared pans.

• Bake for 28–33 minutes, or until the cakes spring back when pressed and a toothpick inserted in the center comes out with a few moist crumbs.

• Let cakes cool in pans for 15 minutes, then turn out onto a rack to cool completely.

Tips for Perfect Results

Room Temperature Ingredients
Bringing eggs, buttermilk, and butter to room temperature helps the cake rise evenly and ensures a smooth frosting.

Use Dutch-Process Cocoa
Dutch-process cocoa creates a darker, more intense chocolate flavor and pairs well with buttermilk.

Don’t Overmix
Stir just until ingredients are combined. Overmixing can make your cake dense or rubbery.

Check for Doneness Early
Ovens vary—start checking your cake at the lower end of the suggested time to avoid overbaking.

Level the Layers
For a professional finish, trim domed tops with a serrated knife before stacking.

Ganache or Buttercream
Ganache creates a rich, truffle-like layer; buttercream is fluffy and ideal for piping. Use both for extra decadence!

Crumb Coat
Apply a thin layer of frosting to seal in crumbs, chill for 15 minutes, then finish with a smooth or decorative layer.

Serving Suggestions

A classic chocolate cake is always a hit, but you can make it even more special:

• Decorate with chocolate curls, gold leaf, or a dusting of cocoa powder.

• Add fresh raspberries, strawberries, or cherries on top for color and a flavor contrast.

• Drizzle with extra ganache for a dramatic look.

• Serve with a scoop of vanilla ice cream or dollop of whipped cream.

• Make mini cakes or cupcakes for parties and celebrations.

• For an adult twist, brush layers with espresso or coffee liqueur before frosting.

Storage and Make-Ahead Tips

Room Temperature
A fully assembled cake can sit covered at room temperature for 1–2 days.

Refrigeration
Store leftover cake in an airtight container in the fridge for up to 4 days. Bring to room temperature before serving for best flavor and texture.

Freezing
Wrap cooled, unfrosted cake layers in plastic and foil. Freeze for up to 2 months. Thaw at room temperature. Buttercream can also be frozen; re-whip before using.

Make-Ahead
Bake cake layers a day ahead for easier handling. Both ganache and buttercream can be made up to 3 days in advance and stored in the fridge; bring to room temperature before assembling.
