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.

Why I Updated This Recipe
This chocolate cake has been one of the most popular recipes on Handle the Heat for years… but something always bothered me.
I kept getting the same question: “How can I make it more moist?” So I went back to my kitchen and tested it again. And again. And again.
After nearly 10 test batches, multiple recipe testers, and a lot of side-by-side comparisons, I realized the answer was counterintuitive: less chocolate actually made a better chocolate cake. Removing the melted chocolate from the batter improved moisture, texture, and flavor, making the recipe quicker, easier, and cheaper to bake!
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.

FAQs
What makes chocolate cake moist?
Oil, brown sugar, and sour cream keep this chocolate cake moist. Oil stays liquid at room temperature, while brown sugar and full-fat sour cream prevent drying.
Can I make this chocolate cake without coffee?
Yes. Replace the espresso powder and water with hot water only. The cake won’t taste like coffee either way.
What are the best cake pans?
I adore my Fat Daddio’s 8-inch cake pans. I prefer the 2-inch deep size. If you use 3-inch-deep cake pans, note that you may experience more cake doming.
Can I make this into a sheet cake?
I haven’t tested that, but I do have a Chocolate Sheet Cake recipe already!
What frosting works best with chocolate cake?
I wrote this recipe with my favorite Chocolate American Buttercream because it’s easy, smooth, and balances the cake without overpowering it. However, you can also use my Chocolate Swiss Meringue Buttercream if you prefer.
Why do my cake layers have big holes in them?
Big holes, or tunnels, happen when the batter is overmixed or ingredients aren’t at room temperature. Overmixing forms strong gluten strands that trap air bubbles, creating holes. To prevent this, mix just until combined, use room-temperature ingredients, and tap your pans before baking to release large air pockets. Also, try sifting your dry ingredients!
Why did my chocolate cake sink?
This is often due to underbaking your cake. Make sure your cake tester or toothpick comes out with moist crumbs, not wet crumbs. Check out my article on how to prevent sinking cakes here.

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.

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!

































Made it for my guest. Everybody just loved it.
I used the regular cocoa powder and skipped the vinegar. Still came out perfect… shared it with my Neighbours too amd got great compliments!
It’s a fool proof recipe… must try!
Just wasn’t sure about how to make the frosting… any videos? I couldn’t see the link too:( so whipped out my own frosting but would love to try this one too:)
I’m so happy everyone enjoyed your cake! If you check out the pink tip box above the cake recipe, I talk about the Swiss Meringue Buttercream Frosting and provided a link to a step-by-step tutorial with a video 🙂
Hello, sounds delicious! I’d like to make a 6 inch 4 layer cake….can I double the cake reciepe?
I haven’t tried baking this recipe in 6-inch pans, so I can’t say for sure how it’d turn out. Will you be baking all four pans at the same time? How deep are your cake pans? Make sure they’re at least 2 1/2-inches deep (I use 3-inch deep pans myself to guarantee they won’t overflow). I normally suggest following cake recipes with the recommended pans to ensure a great outcome or finding a recipe that uses the pans you’d like to use.
The cake looks divine but I’m struggling with the frosting. My whisk attachment I discovered to be missing (I know – how do you lose it?!) and am whisking by hand. Afraid the butter wasn’t fluffy enough before I added the chocolate, so the frosting is beautifully silky but not thick enough. It is chilling now to see if that will help. Will try again after I have replaced the mixer attachment!
You’ll definitely want your whisk attachment for this buttercream recipe to ensure the best outcome, hope you can find it!
Hello, I love and respect the hardworking you put into your recipes but I came across this recipe and your chocolate sheet cake recipe and got confused. I assumed it will be the same ingredients but they are not, is there any reason for using sour cream here versus buttermilk in the sheet cake version, different measurements of granulated sugar and brown sugar compared to the sheet version , different amounts of eggs …
I just wanted to know if there is any reason with regard to taste, type of baking pans , if both recipes can be interchanged or if you have a preference.
I know this is a lot , I over analyze a lot and that’s how I function. I am sorry
No reason other than for the Easy Chocolate Sheet Cake, I went with easy ingredients for people to find and that even possibly already had in their pantry 🙂 I haven’t tested these recipes by switching out ingredients, you’d have to experiment on your own.
Marvelous delicious cake. I have made this with the chocolate frosting and also made it with my regular vanilla butter cream frosting. A huge hit both times!
Delicious! I’m so happy to hear this 🙂
What if I made a 6” -2 layer cake?
We have family members who prefer chocolate cake with white buttercream frosting. Have you ever tried this and does it still taste as good?
I’m more of a chocolate person myself, so I haven’t tried this recipe with vanilla buttercream; however, I’m sure it’d be delicious! You’re welcome to get creative with the flavors and fillings as well!
Wow just made this cake and had it whilst it was still warm with double cream on top.
I have only done the 2 cakes with no buttercream and it was still delicious, soo light, soft, chocolatey and not sickly at all.
I have used regular cocoa powder, used Greek yogurt instead of sour cream.
And used a dark tin as that is all I have at the moment but will look into getting the lighter ones.
Thank you very much for this recipe!
Wonderful! I’m so pleased you loved this recipe and that your substitutions worked perfectly 🙂
Hi Tessa,
I’ve made this cake a couple of times already, huge hit! I followed it to a tee and each time it turned out delicious, I was just wondering though how I would amend the recipe if I want it to fit a number 4 cake tin? The measurements being 13.4″ (34cm) high x 10.6″ (27cm) wide (measured from furthermost edges), also if I make the whole cake one day in advanced will the icing be fine to be on the counter top or do you recommend putting it in the fridge? It will be decorated as well with kit kats and smarties (Ill put the smarties on the morning of the party so the colour does not bleed)
Warm regards

I haven’t tried that, but I always recommend using Wilton’s cake serving guide! If you plan on using this specific buttercream recipe with the egg yolk, I highly recommend refrigerating it. Just make sure you give it some time to come to room temperature the day of your party!
Thank you Tessa,
Should I use your other buttercream recipe just to be on the safe side? It’s for young children or will the SMBC be fine, so long as it’s in the fridge? x
Would this be just as good without the coffee?
I talk about the espresso powder in the pink box above the recipe 🙂
What is the mixture that is added to cakes layers before you add the frosting and then next layer?
Hi Ruth, I’m not sure what you mean, can you elaborate? First there is a cake layer, then a layer of frosting, then the second cake layer, and then the cake is completely covered in frosting. There isn’t an additional mixture added.
I made this amazing cake, it the best chocolate cake I’ve ever tasted!! The frosting is out of this world. So delicious. Gonna make it again. ⭐⭐⭐⭐⭐
