Ingredients

For the Cake:

  • 1 3/4 cups all-purpose flour (220g / 7.8oz)
  • 1 1/2 teaspoons baking powder (7g)
  • 1 1/2 teaspoons baking soda (7g)
  • 1/2 teaspoon salt (3g)
  • 3/4 cup unsweetened cocoa powder (75g / 2.6oz)
  • 2 cups granulated sugar (400g / 14.1oz)
  • 2 large eggs, room temperature
  • 1 cup whole milk (240ml / 8.1fl oz)
  • 1/2 cup vegetable oil (120ml / 4fl oz)
  • 2 teaspoons vanilla extract (10ml)
  • 1 cup boiling water (240ml / 8.1fl oz)

For the Chocolate Frosting:

  • 1/2 cup unsalted butter (113g / 4oz)
  • 2/3 cup unsweetened cocoa powder (65g / 2.3oz)
  • 3 cups powdered sugar (360g / 12.7oz)
  • 1/3 cup whole milk (80ml / 2.7fl oz)
  • 1 teaspoon vanilla extract (5ml)
  • Pinch of salt

Instructions

For the Chocolate Cake:

  1. Preheat your oven to 350°F (175°C). Thoroughly grease two 9-inch (23cm) round cake pans, then line the bottoms with parchment paper. Dust the sides with flour or cocoa powder, tapping out any excess.
  2. In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and cocoa powder until well combined with no visible cocoa lumps.
  3. In a large mixing bowl, combine sugar, eggs, milk, vegetable oil, and vanilla extract. Beat with an electric mixer on medium speed for about 2 minutes until the mixture is smooth and well-integrated.
  4. With the mixer on low speed, gradually add the dry ingredients to the wet mixture in batches, mixing just until incorporated after each addition. Scrape down the sides of the bowl as needed to ensure even mixing.
  5. Carefully add the boiling water to the batter, mixing on low speed until just combined. The batter will be quite thin – this is normal and creates the cake’s characteristic moist texture.
  6. Divide the batter evenly between the prepared cake pans. Tap each pan gently on the counter a few times to remove any large air bubbles.
  7. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs (but no wet batter).
  8. Allow the cakes to cool in the pans for 10 minutes, then run a knife around the edges to loosen. Invert onto wire cooling racks, peel off the parchment paper, and allow to cool completely before frosting.

For the Chocolate Frosting:

  1. In a medium saucepan, melt the butter over low heat, being careful not to brown it.
  2. Once melted, remove from heat and whisk in the cocoa powder until smooth and glossy.
  3. Gradually add the powdered sugar, alternating with the milk, whisking continuously until smooth. Add the vanilla extract and pinch of salt, mixing until fully incorporated.
  4. If the frosting seems too thick, add a little more milk, one teaspoon at a time. If too thin, add additional powdered sugar, one tablespoon at a time, until you reach the desired spreading consistency.

Assembly:

  1. Once the cake layers are completely cool, place one layer on a serving plate or cake stand.
  2. Spread approximately one-third of the frosting over the top of the first layer, extending it just to the edges.
  3. Carefully place the second cake layer on top, ensuring it’s centered.
  4. Apply a thin layer of frosting all over the cake to seal in crumbs (this is called a “crumb coat”), then refrigerate for 15-20 minutes to set.
  5. Spread the remaining frosting over the top and sides of the cake, creating decorative swirls if desired.
  6. Allow the frosting to set for about 30 minutes before slicing and serving.

Cooking Tips and Tricks

  1. Coffee Substitution: For an even deeper chocolate flavor without adding coffee taste, substitute the boiling water with hot freshly brewed coffee. The heat activates the cocoa while the coffee enhances the chocolate notes.
  2. Room Temperature Ingredients: Ensure eggs and milk are at room temperature before mixing. This creates a smoother batter and more even incorporation of ingredients.
  3. Don’t Overmix: Once you add the flour, mix just until combined. Overmixing develops gluten, which can result in a tougher cake.
  4. Even Baking: For perfectly level cake layers, use cake strips around your pans or reduce oven temperature to 325°F (165°C) and extend baking time by 5-7 minutes.
  5. Testing Doneness: The toothpick test is reliable, but you can also gently press the center of the cake – it should spring back when fully baked.
  6. Cooling Completely: Patience is key! Ensure the cake layers are completely cool before frosting to prevent melting and sliding.
  7. Frosting Technique: For a smoother finish, heat your metal spatula or knife under hot water, wipe dry, and then use it to spread the frosting.

Variations and Substitutions

  1. Gluten-Free Version: Replace all-purpose flour with a 1:1 gluten-free flour blend that contains xanthan gum.
  2. Dairy-Free Alternative: Use plant-based milk (almond, oat, or soy) and dairy-free butter substitutes in both the cake and frosting.
  3. Reduced Sugar Option: Decrease sugar in the cake to 1 1/2 cups and use 2 1/2 cups powdered sugar in the frosting for a less sweet version.
  4. Flavor Variations:
    • Add 1 teaspoon of espresso powder to the dry ingredients
    • Include 1/2 teaspoon of cinnamon and a pinch of cayenne for a Mexican chocolate twist
    • Mix in 1 tablespoon of orange zest to the batter for chocolate-orange flavor
    • Add 1/4 teaspoon of almond extract to the batter for subtle depth
  5. Frosting Alternatives:
    • Cream cheese frosting with a touch of cocoa
    • Vanilla buttercream for contrast
    • Chocolate ganache for an extra-decadent coating
  6. Filling Options:
    • Spread raspberry jam between layers
    • Add a layer of chocolate mousse
    • Include sliced strawberries on top of the filling

Common FAQs

Q: Why is my cake batter so thin? Did I do something wrong?

A: The thin batter is intentional and a hallmark of this recipe! The addition of boiling water creates a loose batter that results in an exceptionally moist cake with tender crumb. Trust the process – it works!

Q: Can I make this cake in advance?

A: Yes! The cake layers can be baked up to 2 days ahead, cooled completely, and wrapped tightly in plastic wrap. Store at room temperature. The frosting can be made 1 day ahead and stored in the refrigerator – just bring to room temperature and re-whip before using.

Q: My cake is sticking to the pan. How can I prevent this?

A: Be thorough when preparing your pans: grease them generously, line the bottoms with parchment paper, and dust the sides with either flour or cocoa powder. Allow the cakes to cool for exactly 10 minutes in the pans before removing – too soon and they may break, too long and they might stick.

Q: Can I use natural cocoa powder instead of Dutch-processed?

A: This recipe works with either type of cocoa powder. Natural cocoa powder will give a slightly more acidic flavor profile, while Dutch-processed provides a smoother, mellower chocolate taste.

Q: How do I convert this recipe for cupcakes?

A: This batter yields approximately 24-30 standard cupcakes. Fill liners 2/3 full and bake at 350°F (175°C) for 18-22 minutes. Reduce the frosting recipe by 1/3 for a perfect amount to top the cupcakes.

Storage and Make-Ahead Tips

  1. Room Temperature Storage: The frosted cake can be stored at room temperature, covered with a cake dome or loosely with plastic wrap, for up to 3 days.
  2. Refrigeration: For longer storage, refrigerate the frosted cake, covered, for up to 5 days. Allow slices to come to room temperature before serving for the best flavor and texture.
  3. Freezing Unfrosted Layers:
    • Cool completely
    • Wrap each layer individually in plastic wrap, then in aluminum foil
    • Freeze for up to 2 months
    • Thaw overnight in the refrigerator before unwrapping and frosting
  4. Freezing Frosted Cake:
    • Place the frosted cake in the freezer, uncovered, until the frosting hardens
    • Wrap the entire cake securely in plastic wrap, then in aluminum foil
    • Freeze for up to 1 month
    • Thaw overnight in the refrigerator with wrapping intact, then bring to room temperature before serving
  5. Make-Ahead Timeline for Special Occasions:
    • Up to 2 months before: Bake cake layers and freeze
    • 2 days before: Thaw cake layers in refrigerator
    • 1 day before: Prepare frosting and assemble cake
    • Day of serving: Bring to room temperature for 1-2 hours before serving
