Ingredients List

    • 2 cups all-purpose flour
    • 2 cups granulated sugar
    • ¾ cup unsweetened cocoa powder
    • 2 teaspoons baking powder
    • 1½ teaspoons baking soda
    • 1 teaspoon salt
    • 2 large eggs
    • 1 cup whole milk
    • ½ cup vegetable oil
    • 2 teaspoons vanilla extract
    • 1 cup boiling water

For the Chocolate Frosting:

    • 1 cup unsalted butter, softened
    • 3½ cups powdered sugar
    • ½ cup unsweetened cocoa powder
    • ½ cup heavy cream
    • 2 teaspoons vanilla extract
    • ¼ teaspoon salt
    • Optional: chocolate shavings or sprinkles for decoration

Timing / Cooking Schedule

Prep time: 20 minutes

Cooking time: 35 minutes

Total time: 55 minutes (plus 1 hour cooling time)

This timeline doesn't include frosting preparation, which adds another 10 minutes. Plan for approximately 2 hours from start to finish to allow proper cooling before frosting your cake.

Step-by-Step Instructions

Step 1: Prepare Your Workspace Preheat your oven to 350°F (175°C). Grease two 9-inch round cake pans and line the bottoms with parchment paper for easy removal. This prevents sticking and ensures clean layers.

Step 2: Mix Dry Ingredients In a large mixing bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt. Sifting the cocoa powder eliminates lumps and creates a smoother batter texture.

Step 3: Combine Wet Ingredients Add eggs, milk, oil, and vanilla extract to the dry mixture. Beat on medium speed for 2 minutes until well combined. The batter will be thick at this stage.

Step 4: Add Boiling Water Carefully stir in the boiling water—the batter will become thin, which is completely normal. This step creates the incredibly moist texture that makes this chocolate cake with chocolate frosting so special.

Step 5: Bake Divide batter evenly between prepared pans. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Avoid opening the oven door during the first 25 minutes to prevent sinking.

Step 6: Prepare the Frosting While cakes cool, beat softened butter until creamy. Gradually add powdered sugar and cocoa powder, alternating with heavy cream. Add vanilla and salt, then beat for 3-4 minutes until fluffy. This creates one of the best chocolate cake frosting recipes you'll ever try.

Step 7: Assemble Once cakes are completely cool, place one layer on a serving plate. Spread frosting on top, add the second layer, then frost the top and sides generously.

Tips, Variations, or Cooking Advice

Dietary Adaptations: For a gluten-free version, substitute with 1:1 gluten-free flour blend. Make it dairy-free by using almond milk and coconut oil instead of dairy products.

Flavor Variations: Add espresso powder to intensify chocolate flavor, or incorporate peppermint extract for a refreshing twist. For a mocha version, replace half the milk with strong brewed coffee.

Make-Ahead Options: Bake cake layers up to 2 days ahead, wrap tightly in plastic wrap, and refrigerate. Frost the day of serving for best results.

Common Mistakes to Avoid

Overmixing the Batter: Mix just until ingredients are combined. Overmixing develops gluten, resulting in a dense, tough cake instead of a tender crumb.

Frosting Warm Cake: Always allow cakes to cool completely before frosting. Warm cake causes frosting to melt and slide off, ruining your presentation.

Incorrect Oven Temperature: Use an oven thermometer to verify accuracy. Too hot burns the edges while leaving centers underbaked; too cool results in dry, overbaked cake.

Skipping Parchment Paper: This simple step prevents frustration when removing cakes from pans and ensures professional-looking layers.

Storage / Leftovers Tips

Store your chocolate cake with chocolate frosting in an airtight container at room temperature for up to 3 days, or refrigerate for up to 1 week. For longer storage, wrap unfrosted layers individually in plastic wrap and aluminum foil, then freeze for up to 3 months. Thaw overnight in the refrigerator before frosting.

When exploring different chocolate cake frosting recipes, remember that buttercream-frosted cakes freeze well, but cream cheese or whipped frostings should not be frozen. To refresh refrigerated cake, let it sit at room temperature for 30 minutes before serving to restore its soft, moist texture. Store leftover slices in airtight containers with parchment paper between layers to prevent sticking.
