Best Chocolate Cake

This is the best chocolate cake I’ve ever made, no joke. It’s deeply chocolatey, ultra-moist, and surprisingly easy. (Apologies in advance for the excessive use of the word “moist.”)

After 7 years of reader feedback and over a year of testing, I simplified the ingredients, improved the texture, and made it more moist than ever. The result is a homemade chocolate cake that stays soft for days and tastes rich without being too heavy or overpowering.

Ingredient Notes

Dutch-Process Cocoa Powder
This recipe relies on cocoa powder for the primary chocolate flavor. Cocoa powder actually transmits more chocolate flavor than solid chocolate. Dutch-process cocoa creates a smoother, darker, more balanced chocolate taste without bitterness.

Espresso Powder + Hot Water (Or Coffee)
Espresso powder intensifies chocolate flavor without making the cake taste like coffee. Blooming cocoa powder in hot liquid releases fat-soluble flavor compounds, giving the cake a deeper chocolate taste. Hot coffee works too, as well as just hot water if you don’t drink coffee.

Light Brown Sugar
Brown sugar adds moisture and softness thanks to its molasses content. In testing, replacing granulated sugar with all brown sugar yielded a more moist and flavorful cake that stayed moist for longer.

Sour Cream
This is a key moisture and flavor ingredient! The acidity activates the baking soda and, coupled with the fat content, tenderizes the texture and balances the sweetness with its distinct tang. Use full-fat for best results. You can also use full-fat plain yogurt.

Eggs
Eggs are key to both structure and richness. Room-temperature eggs emulsify better, creating a smoother batter and more even crumb. I have yet to find a suitable substitute for eggs.

Oil (Not Butter)
Oil stays liquid at room temperature, which keeps this chocolate cake moist for longer than butter-based cakes. Use any neutral oil that doesn’t solidify: vegetable, canola, avocado, etc., but not coconut oil.

How to Make Chocolate Cake (Step by Step)

Prep the pans and oven
Preheat your oven to 350°F. Line two 8-inch round cake pans with parchment rounds (I like these ones with pull tabs!) and spray with nonstick spray (I like Baker’s Joy). This ensures a clean release.

Bloom the cocoa
Pour boiling water over the cocoa and espresso powder (or use coffee). Whisk until smooth and glossy. Set aside to cool completely. This “blooms” the chocolate flavor compounds in the cocoa.

Mix the dry ingredients
In a large bowl, whisk together the flour, salt, and baking soda. Add the brown sugar and whisk or use your fingers to break up any clumps until it looks like sand.

Combine the wet ingredients
In a separate bowl, whisk the sour cream, oil, eggs, and vanilla until smooth.

Make the batter
Create a well in the dry ingredients and pour in the wet mixture. Mix gently from the center outward until mostly combined. Avoid overmixing, which can cause “tunnels” in your baked cake or make the final texture rubbery.

Add the cocoa mixture
Pour in the cooled (!) cocoa mixture and whisk until the batter is smooth and evenly combined. If this mixture is too hot, it’ll overly activate the baking soda and cause doming.

Bake
Divide evenly between pans (about 740 grams per pan if you’re using a scale). Tap pans on the counter to remove air bubbles. Bake 32–35 minutes, until a toothpick comes out with moist crumbs.

Cool completely
Cool in pans for 30 minutes, then turn out onto a rack and cool fully before frosting. For even easier frosting, chill the cake layers in the fridge for 30 minutes beforehand.

Cake Decorating Tips

There are a few products + tricks that make cake decorating a breeze. Luckily, this recipe is particularly easy to assemble and decorate. The cake layers are sturdy and the frosting is so velvety smooth that it’s perfect for beginners. 

• Parchment Strips: Cut and tuck rectangular strips of parchment underneath the border of your base cake layer to catch stray frosting for quick and easy cleanup and presentation.
• Cake Leveler (optional): If your cake has domed at all, this makes easy work of leveling it flat for easier assembly and frosting. You can also use a serrated knife.
• Cake Turntable (optional): This is basically a lazy susan for cake, and it makes decorating so quick, easy, and enjoyable. I like to place my cake plate on top of this so I don’t need to worry about moving a frosted cake later.
• Offset Spatula: Practically an essential tool for cake decorating with any semblance of smooth and even frosting.

Sprinkle of Science

Why removing melted chocolate made this cake better:

Solid chocolate firms up as it cools. That’s because it’s saturated fat, like butter. This can create a tighter crumb and denser texture in cake that dries out faster. 

Cocoa powder, on the other hand, delivers intense chocolate flavor without adding a ton of saturated fat that solidifies. Combined with oil (which stays liquid), the result is a cake that’s softer, more flavorful, and stays moist longer.

Storage & Make Ahead

Frosting: Cover and refrigerate for up to 2 days. Bring to room temperature and re-whip before using. It will oxidize (darken in color), but this won’t affect flavor or texture.

Unfrosted cake layers: Wrap and freeze for up to 2 months.

Frosted cake: Refrigerate for up to 2 days. Serve chilled for an extra fudgy cake, if desired!

Freezing leftovers: Freeze slices for up to 2 months. Freeze on a parchment-lined baking sheet until solid, then wrap in plastic and place in an airtight container. Thaw overnight in the fridge.

Test Kitchen BTS

This recipe underwent about 20 iterations between myself and four recipe testers in four different states.

We experienced just about every issue you could imagine: sinking, doming, tunneling, dry edges, sticky cake layers, etc. I gave away multiple cakes and involved many friends in taste testing! It was a journey.

Ingredients 

For the cake:

• ▢ 1 cup (85 grams) Dutch-process cocoa
• ▢ 2 teaspoons instant espresso powder*
• ▢ 1 cup (237 grams) boiling water
• ▢ 1 3/4 cups (222 grams) all-purpose flour
• ▢ 1 teaspoon fine sea salt
• ▢ 1 teaspoon baking soda
• ▢ 2 cups (400 grams) lightly packed light brown sugar
• ▢ 1 cup (227 grams) sour cream or full-fat plain yogurt, at room temperature
• ▢ 4 large eggs, at room temperature
• ▢ 1/2 cup (112 grams) neutral oil, such as canola or avocado oil
• ▢ 2 teaspoons vanilla extract
• ▢ 1 batch Chocolate Buttercream Frosting

Instructions 

Make the cake:

• Preheat the oven to 350°F. Line two 8 by 2-inch cake pans** with parchment rounds and spray evenly with nonstick cooking spray.
• In a small heatproof bowl, whisk together the cocoa powder and espresso powder. Pour the boiling water over mixture and whisk gently until smooth. Set aside to cool completely.
• In a large bowl, either sift*** or whisk together the flour, salt, and baking soda. Add brown sugar and use your hands to break up any clumps until the mixture resembles sand.
• In a separate small bowl, whisk together the sour cream, oil, eggs, and vanilla until smooth. Make a well in the center of the dry ingredients and pour in the wet ingredients. Starting in the center, use a whisk to slowly pull the dry ingredients into the wet until mostly combined. The batter may be slightly lumpy.
• Add the cooled cocoa mixture and whisk until the batter is smooth and evenly combined.
• Divide the batter evenly between the prepared pans (about 740 grams per pan). Tap each pan firmly on the counter a few times to pop any air bubbles. Bake for about 32 to 35 minutes, or until a toothpick or cake tester comes out with moist crumbs attached.
• Cool in the pans for 30 minutes, then (if needed) run a thin knife around the edges and remove to a wire rack to cool completely.

Assemble the cake:

• If your cake has domed at all, level with a serrated knife or cake leveler until it is flat.
• Place one cake layer on a cake turntable or cake stand. Place strips of parchment paper under the cake to prevent a frosting mess.
• Spread a generous, even layer of frosting over the top, pushing it out over the edges slightly. Place the second layer upside down onto the frosting so the top of the cake is nice and flat.
• Using an offset spatula, spread the remaining frosting evenly all over the cake, smoothing the edges. Serve immediately, or cover and refrigerate for up to 2 days. Let sit at room temperature for an hour before serving.

Recipe Notes

*If you don’t have espresso powder, you can replace both the espresso powder and boiling water with 1 cup hot strong coffee. If you don’t like the taste of coffee or espresso, just use hot water and omit the espresso powder completely.

**Using 8 by 3-inch pans instead will give you slightly domed tops. You may want to level them before assembly.

***If you commonly experience cake tunneling (lots of holes in your cake layers) then I recommend taking the time to sift these dry ingredients together.

I made this chocolate cake for my dad’s birthday and it was a big hit! PS: Can you see my husband’s smiling proud face in the reflection of the microwave? Ha!
