Ingredients

To create this incredible dark chocolate cake, gather these simple ingredients. Each component plays a vital role in achieving its signature rich flavor and moist texture.

For the Cake

• 3 cups all-purpose flour
• 3 cups granulated sugar
• 1 cup + 2 Tablespoon unsweetened cocoa powder (I love to use Hershey’s Special Dark, but regular works)
• 3 teaspoons baking powder
• 2 1/4 teaspoons baking soda
• 1 1/2 teaspoons salt
• 1 1/2 cups milk
• 3/4 cup oil (vegetable or canola oil)
• 3 large eggs, room temperature
• 3 teaspoons vanilla extract
• 1 1/2 cups boiling water

For the Dark Chocolate Frosting

• 5 1/2 cups powdered sugar
• 1 1/3 cups unsweetened cocoa powder
• 12 Tablespoons unsalted butter, softened to room temperature
• 1 cup heavy cream
• 2 teaspoons vanilla extract

Notes & Substitutions

For the best dark chocolate cake flavor, consider your cocoa powder choice. Natural cocoa powder is more acidic, while Dutch-processed cocoa powder is less acidic and delivers a darker color and milder flavor. To understand how these choices impact your bake, exploring the chemical distinctions between them is helpful, as detailed by King Arthur Baking on the difference between natural and Dutch-processed cocoa powder. Hershey’s Special Dark combines both for a truly deep, rich taste. Always use room temperature ingredients like eggs and milk. This helps them emulsify better with other ingredients, creating a smoother batter and a more even cake texture. Understanding how room temperature affects emulsion and texture can significantly improve your baking results; learn more about the science behind using room temperature ingredients in baking. If you need an alternative to vegetable or canola oil, use another neutral-flavored oil like sunflower oil. For dairy-free options, almond milk, soy milk, or oat milk work well in place of regular milk. You can also substitute heavy cream with full-fat coconut milk (canned) for the frosting. Use a plant-based butter substitute in the frosting to make it dairy-free. For a vegan alternative to eggs, try flax eggs (1 tablespoon ground flaxseed meal mixed with 3 tablespoons water per egg, let sit for 5 minutes).

Equipment

Having the right tools makes baking this dark chocolate cake a breeze. Gather your equipment before you begin.

• Three 9-inch cake pans
• Parchment paper
• Large mixing bowls
• Electric stand or hand mixer
• Measuring cups and spoons
• Rubber spatula or offset spatula
• Cooling racks

Instructions

Creating this luscious dark chocolate cake is a straightforward process when you follow these steps carefully. You will be amazed at how simple it is to achieve such a decadent dessert.

For the Cake

1. Preheat oven and prep cake pans: Preheat your oven to 350°F (175°C). Grease and flour three 9-inch round cake pans. Line the bottoms with parchment paper for easy removal.
2. Whisk dry ingredients in large bowl: In a very large mixing bowl, whisk together the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking powder, baking soda, and salt. Make sure there are no lumps and all ingredients are evenly distributed. This forms the base of your moist dark chocolate cake.
3. Add milk, oil, eggs, vanilla; mix well: To the dry ingredients, add the milk, vegetable or canola oil, large eggs, and vanilla extract. Mix on low speed with an electric mixer until just combined. Do not overmix at this stage; a few lumps are fine.
4. Slowly add boiling water; beat on high: Carefully pour the boiling water into the batter while mixing on low speed. Once added, increase the mixer speed to high and beat for exactly 2 minutes. The batter will be thin, which helps create an extra moist crumb.
5. Divide batter evenly into pans: Pour the thin cake batter evenly among the three prepared cake pans. You can use a kitchen scale to ensure precise distribution for even layers.
6. Bake until toothpick comes out clean: Bake for 30–35 minutes, or until a wooden toothpick inserted into the center of a cake comes out clean. Baking times can vary, so start checking early.
7. Cool cakes completely on racks: Remove the cakes from the oven and let them cool in their pans for about 10–15 minutes. Then, invert them onto wire cooling racks, remove the parchment paper, and allow them to cool completely before frosting. This prevents the frosting from melting.

For the Dark Chocolate Frosting

1. Stir together powdered sugar and cocoa: In a medium bowl, whisk together the powdered sugar and unsweetened cocoa powder until thoroughly combined. This prevents lumps in your smooth frosting.
2. Beat softened butter until pale and fluffy: In a large mixing bowl, using an electric mixer, beat the softened unsalted butter on medium-high speed for 3–5 minutes. Beat until it becomes light in color and fluffy in texture.
3. Gradually add dry mixture, cream, and vanilla: With the mixer on low speed, gradually add the powdered sugar and cocoa mixture to the butter, alternating with splashes of heavy cream. Add the vanilla extract during this process.
4. Beat on high speed until light and fluffy: Once all ingredients are incorporated, increase the mixer speed to high. Beat for another 2–3 minutes until the frosting is light, fluffy, and spreadable. This creates the perfect texture for your dark chocolate cake topping.

Assemble the Cake

1. Place first cake layer on platter: Place one cooled cake layer onto your serving platter or cake stand. If the top of the cake is domed, use a serrated knife to level it gently.
2. Spread generous frosting layer evenly: Using an offset spatula or knife, spread about 1 to 1 1/2 cups of the dark chocolate frosting evenly over the top of the first cake layer. Spread it right to the edges.
3. Add second layer; repeat frosting: Carefully place the second cake layer on top of the frosted first layer. Spread another generous layer of frosting over this second layer, just as before.
4. Add third layer; frost top and sides smoothly: Place the final cake layer on top. Now, use the remaining frosting to generously cover the top and sides of the entire cake. Use your spatula to smooth out the frosting for a clean finish.
5. Decorate with sprinkles or piping (optional): For an extra touch, decorate your finished dark chocolate cake with chocolate sprinkles, chocolate shavings, or use a piping bag to add decorative swirls or borders around the edges.

Pro Tips for the Best Dark Chocolate Cake

Follow these expert tips to ensure your dark chocolate cake turns out perfectly every time. These simple tricks make a big difference in the final result.

• Room Temperature Ingredients: Always use room temperature eggs and milk. This helps create a smooth, emulsified batter, leading to a lighter and more uniform cake texture.
• Do Not Overmix: Mix the batter only until just combined. Overmixing develops the gluten in the flour, which can result in a tough, dry cake.
• Measure Dry Ingredients Correctly: Spoon flour into your measuring cup and then level it off with a straight edge. Scooping directly can compact the flour, leading to too much dry ingredient.
• Don’t Overbake: Keep a close eye on your cakes during baking. Overbaking is the quickest way to dry out a cake. Remove them as soon as the toothpick test is clean.
• Cool Completely: Ensure your cake layers are completely cool before you attempt to frost them. Warm cakes will melt your beautiful dark chocolate frosting.
• High Altitude Adjustments: For high-altitude baking, you might need to make minor adjustments. Generally, reduce baking powder slightly, increase liquid, and potentially add a little more flour to prevent sinking.

Serving, Storage & Variations

This impressive dark chocolate cake is versatile for serving and storage. Explore these ideas to enjoy your creation to the fullest.

Serving Suggestions

• Serve individual slices with a handful of fresh berries like raspberries or strawberries.
• Enhance the experience with a generous scoop of good quality vanilla bean ice cream.
• A light dusting of unsweetened cocoa powder over the top adds a touch of elegance.
• Enjoy your slice with a strong cup of coffee or a cold glass of milk for a delightful treat.

Storage Instructions

• Countertop: Store your frosted dark chocolate cake covered tightly at room temperature for up to 2-3 days. A cake dome works wonderfully.
• Refrigerator: For longer storage, keep frosted cake chilled in the refrigerator, tightly covered, for up to 5 days. Bring it to room temperature before serving for the best flavor and texture.
• Freezing Unfrosted Layers: Wrap individual unfrosted cake layers securely in plastic wrap, then aluminum foil. Freeze for up to 2-3 months. Thaw in the refrigerator before frosting.
• Freezing Frosted Cake: For a whole frosted cake, freeze uncovered until firm, then wrap tightly in plastic wrap and foil. Thaw overnight in the refrigerator, then bring to room temperature.

Variations

• Adjusting Cake Layers: Easily make a 2-layer cake by dividing the batter into two 9-inch pans and baking slightly longer. For a taller, more elegant 4-layer cake, use four 8-inch pans.
• Gluten-Free: Substitute the all-purpose flour with a 1:1 gluten-free all-purpose flour blend. Ensure your blend contains xanthan gum.
• Dairy-Free: Replace milk with a dairy-free milk alternative and heavy cream with full-fat canned coconut milk. Use a plant-based butter substitute in the frosting.
• Vegan: Combine dairy-free substitutions with flax eggs (1 tbsp ground flaxseed + 3 tbsp water per egg) for a completely vegan dark chocolate cake.
• Add Espresso Powder: Stir 1-2 teaspoons of instant espresso powder into the boiling water to intensify the chocolate flavor without adding coffee taste.
• Different Fillings: Between layers, try a vibrant raspberry compote, a rich chocolate ganache, or even a salted caramel sauce for a new flavor profile.

Your cake likely sank due to several reasons, such as opening the oven door too early, inaccurate oven temperature, or overmixing the batter. Ensure your baking powder and soda are fresh.

Can I use a different type of oil?

Yes, you can use any neutral-flavored oil like canola, sunflower, or grapeseed oil. Avoid strong-flavored oils like olive oil, which can affect the taste of your dark chocolate cake.

How long does homemade dark chocolate cake last?

A homemade dark chocolate cake can last 2-3 days at room temperature when covered. When refrigerated, it stays fresh for up to 5 days.
