Easy, Moist Chocolate Cake for Everyday Baking

I try to keep things simple in my kitchen and on this blog. You won’t find a lot of complicated, time-consuming recipes here. Sure, I get overly ambitious from time to time (ahem: Chocolate Peppermint Cake), but I generally like to keep things approachable and attainable.

That said, I actually resisted making this cake for a while because it seemed almost too simple. I mean, it’s a no-frills chocolate cake; as much as I love chocolate, most of the time I prefer it with just a little extra interest.

Then, today I decided I would finally make this cocoa cake recipe and let me tell you, I was wrong: it is not just a chocolate cake. The simplicity of this recipe is also the beauty of it. It’s much like what cake mixes wish they could produce.

Every dessert has its place. This is not necessarily a cake to make if you want to wow a crowd—there are no layers, no piped-on rosettes of frosting, and no surprises inside. But, it’s a great cake to whip up when you want to revel in a bit of pure chocolate goodness.

Dutch-Process Cocoa Powder vs. Natural Cocoa Powder

When it comes to cocoa powder, the two most widely-available varieties are Dutch-process cocoa and natural cocoa.

Natural cocoa is the more popular of the two—think of it as your traditional cocoa powder. It’s made by removing the cocoa butter from cacao, leaving behind a fine powder.

Dutch-process cocoa takes things a step further by removing the cocoa butter and adding an alkalizing agent, which reduces the cocoa’s acidity. Dutch-process cocoa has a smoother flavor, and it’s darker in color.

Unless a recipe specifies one or the other, you can use either. (That’s the case for this cocoa cake recipe.) But—and this is a big but!—if a recipe calls for a specific type of cocoa, you should not substitute the other. Because natural cocoa powder is more acidic, it behaves differently in a recipe than Dutch-process cocoa, so it can throw off how a recipe rises (or not) if you use the wrong type of cocoa powder.

How to Make Cocoa Cake

Here’s what you’ll need to do to make this simple chocolate cake:

Prepare. Preheat your oven to 350°F and grease a 9-inch round cake pan with butter. Dust the pan with flour, then tap out the excess.

Combine the dry ingredients. Whisk the flour, cocoa, baking soda, and salt in a mixing bowl.

Mix the wet ingredients. Use an electric mixer on medium speed to beat the butter and brown sugar until the mixture is pale and fluffy. Beat in the eggs one at a time, followed by the vanilla.

Finish the batter. Add the dry mixture to the wet mixture in batches, alternating with water and beginning and ending with the dry ingredients. Mix until just combined.

Bake. Pour the batter into the prepared pan and bake for 55 to 60 minutes, or until the cake springs back when you gently poke it and a toothpick inserted into the center comes out clean.

Cool and serve. Let the cake cool in the pan for an hour; carefully invert it onto a wire rack, then again onto a serving plate. Dust with confectioners’ sugar before slicing and serving.

Tips for Success

Want to make sure your cocoa cake turns out perfect? These hints and tips will help!

  • Don’t skip the flouring. When you’re making a cake with frosting, you can cover over any imperfections if the cake doesn’t come out of the pan smoothly. Because this cake isn’t frosted, if some of it sticks to the side of the pan when you invert it, it will show. This is why flouring the pan is so important! It’s the best way to keep the cake from sticking. If you have a cooking spray with flour, that should work, too.
  • Use room temperature ingredients. You’ll always get fluffier baked goods when your ingredients are at room temperature when you start a recipe. That’s because the batter is able to hold more air when it’s beaten, and more air means a light, fluffy texture. Depending on how warm your kitchen is, don’t let the butter come quite all the way to room temperature, as that may be too soft for creaming. Read more: How to Soften Butter
  • Don’t over-mix. It’s always better to have a few streaks of flour on the side of the bowl than to mix the heck out of your batter. Over-mixing means the flour will form tough gluten strands, which is terrible for the texture of your cake.

Simple Cake Topping Ideas

Although the appeal of this cake is its simplicity, if you’re making it for an impromptu get-together, you might want to jazz it up a little bit with some garnishes that you already have on hand. Here are some ideas:

  • Add fresh fruit. Arrange strawberries, raspberries, and blueberries on the top of the cake to gussy it up. In the fall, pomegranate arils are pretty, too.
  • Serve it with whipped cream. Homemade sweetened whipped cream is a cinch to make!
  • Drizzle it with salted caramel. Add toasted or glazed pecans, too, for a turtle-inspired dessert!

  12. This looks so good. I was going through the recipe but can’t seem to figure out where the water comes into it. Am I missing something?

  13. Let me preface with the fact that this is my favorite site!! LOVE IT! I am a baker and enjoy every photo you put on! Have had a slew of friends sign up for it! Now, made this today. Although I love most of the goodies on this website, this was just too bland. I ended up putting chocolate frosting on top just to give it some “oomph”!! Nowhere near chocolatey enough for me! Also, I would love it if people would post comments on this site that are constructive to the actual item. 95% of the comments are how good it looks or how hungry the picture makes them! Why don’t we put things that matter- like, “too sweet”,or “delicious?”!! I wish people would comment AFTER they baked the item! Just Sayin’!!

    • Lisa- My thoughts EXACTLY! We all know the pics are gorgeous, but the reason I scan all the reviews, is to find someone who ACTUALLY MADE the cake, not just loved the pics, or how they are going to make it, or how they are drooling over it! I too am a chocoholic and need cakes that are full of flavor! Maybe some coffee instead of water would be a nice boost of flavor, but thank you for your input! You’re the only one who MADE it, and I was wondering how the taste is.! So Thanks again! ( I too am a Lisa!)

  14. Awesome recipe. Simplicity rocks as always.

  15. I am a house husband.
    Tried this cake today.
    350 º what ??
    I tried 350 cº & then came to know that it is 350º F =180º C.
    Feeling Low !!
    🙁

  16. Looks like a yummy but quick to make chocolate cake recipe. I love recipes that use ingredients I am likely to have in the cupboard. Thanks for sharing 🙂

  17. It was so easy. I had to replace with Gluten free flour and the butter with oil. But everytime I bake these kind of cakes, it always breaks on the top. Its not smooth on the top. What should I be doing that this doesnt happen. This is not the first time

    • Cakes most often crack on top because the oven temperature is too high. I’d recommend getting an oven thermometer to check the accuracy of your oven’s temperature. Also, opening the oven door frequently while the cake is baking can cause cracking. I don’t bake with gluten-free flour, so I can’t say if that could be causing any issues.

  18. Lovely recipe. Although the water content in the cake evaporates, leaving the cake to be dry n muddy. The second time i baked, i replaced the butter with oil n also substituted buttermilk.

  19. This recipe was perfect for my grandson and to baked. We used a cup of water only and it came spongy. We loved it.

  20. Made this with my 4 year old, simple but very tasty!
    Thanks for the recipe

  21. I don’t know why I torture myself! I live at 7,200’ elevation so cakes are out of the question😥

  22. Dutch processed cocoa or natural?

  23. Don’t try this in a 9inch pan that isn’t over two inches deep. Lit my oven on fire and the house smells like a burned-out chocolate factory. That said, my bad for thinking close to two inches is enough. Was able to spatula some of the burned batter from the spillage and it’s fantastic. Serving the other half later tonight.
