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!

































The cake turns good on a finished product but the texture isn’t so impressive because the vinegar reacted with the baking soda. Bubbles came out and lot of holes. I personally don’t agree with vinegar.
I have never prepared a cake using the method you described in your recipe but I went for it. The cake was excellent. Typically I will sift together my dry ingredients and add this to the butter ( or oil in this case), egg, sugar ect. alternating adding the wet and dry ingredients at the end. Just curious if this is your usual method for mixing cakes or something you developed for this recipe?
What an amazing recipe!! I used low fat yougurt as that’s all I had. I also used double cream for the centre and a different buttercream recipe for the top but it was all lovely! Thanks
Looking forward to making for my Family- can I use whole wheat flour?
Hi Tessa,
How much hot water is added to the chocolate cocoa mixture? Wasn’t clear from the directions on how much water is added to it.
Made this today and it is amazing…the butter cream is to die for.
Made this to celebrate my birthday! I had a chance to try it before the celebration (ate the pieces I shaved of the top of the bottom layer). Ah- mazing!!! So chocolatey and moist! The frosting is so smooth, and easy to spread. The combination of the two is heaven! Thank you for such an amazing recipe!
Truly delicious dense chocolate cake, love it, love it, love it!!!
Hi Tessa,
Thanks for your recipe! This looks so great that I wanna try it. It says to use 8″ round cake pan. My 8″ is a dark springform pan. Since the batter is gonna be loose, should I worry about it leaking? My other pan is only 6″.
I made this cake for my mother-in-law’s birthday last month. This was the best chocolate cake recipe I have ever used. It was moist and full of flavor, the addition of the coffee is spot on! Love love love and will make it again!!
hi,
may i use hot milk instead of hot water? thank you.
This cake was so easy i made it with a baby strapped to my chest. I even messed up a few times and it still turned out delicious.
I substituted coconut oil for butter in the butter cream because I didn’t have any unsalted butter and it turned out amazing!!! it just had to spend some extra time in the fridge before it could be finished as the warm egg whites turned the coconut oil into liquid.
