Why this is the BEST Chocolate Cake Recipe

Let’s head back to basics with this chocolate cake recipe! I already have a lot of basic recipes on this blog (like yellow cake, sugar cookies, red velvet, etc.) and I’m trying to complete the list. While I already have a chocolate cupcake recipe (which really an amazing recipe), I wanted a versatile chocolate cake recipe too.

I worked extra hard to come up with a chocolate cake that is:

  • Moist and tender
  • Super chocolatey and rich but not overly so
  • Easy to work with, with a simple batter
  • Can make cupcakes OR any cake

Whether you’re looking to make a perfect 8-inch or 9-inch layer cake, a 9×13-inch sheet cake, or 24 wonderful cupcakes, this chocolate cake recipe is the only one you need in your arsenal. You can use any frosting, but my fudgy chocolate frosting is by far my favorite.

Ingredients Needed

  • It has the usual cake making suspects: sugar, all-purpose flour, and eggs.
  • Cocoa is a usual ingredient in chocolate cake, and you can use natural unsweetened cocoa powder or special dark (that Hershey’s one) but you cannot use dutch process in this cake. (Read about cocoa.)
  • Oil: I love using oil instead of butter in a lot of my cakes. I find that a liquid fat gives more moisture in a cake than a solid one, hence using oil or melted butter.
  • Baking Soda and Baking Powder: The two work in tandem to create lift and keep the cake light and airy. Baking soda requires an acid to help it activate (like buttermilk). Baking powder is made up of baking soda and enough acid to already cause the reaction. Using them both gives the extra lift needed that baking soda alone wouldn’t be able to give. (Learn more about baking soda vs baking powder.)
  • Buttermilk: Since baking soda requires an acid to activate it and make it work, that’s why I used buttermilk. That tanginess of the buttermilk acts as an acid that helps the baking soda work.
  • Hot water: when added to a chocolate cake recipe, it helps to bloom the cocoa. Blooming the cocoa is an important step because it brings out the flavor and adds depth to the cake. Don’t skip the hot water!

How to make Chocolate Cake

  • Whisk granulated sugar, cocoa powder, baking soda, baking powder, salt, and flour in a large bowl.
  • Stir together buttermilk, hot water, oil, eggs, and vanilla extract.
  • Add the wet ingredients into the dry ingredients and whisk until batter forms without lumps.
  • Pour into prepared cake pans or cupcake pans. Bake until a toothpick comes out clean.

Best Chocolate Fudge Frosting

Honestly, I can eat this cake plain, but I’m weird. Vanilla frosting or cream cheese frosting is amazing. So is my Brown Butter Chocolate Frosting.

This recipe uses another favorite chocolate frosting that is super fudgy. What makes it so good and fudgy? Melted Butter!

Besides the melted butter, this frosting has the other usual subjects: powdered sugar, cocoa, salt and vanilla.

It also uses milk to thin it and it is important you use whole milk (low-fat or non-fat is fine too) and not heavy cream. Heavy Whipping Cream will make it too gloppy to spread.

The most important tip about the frosting is that, because it starts with melted butter, you have to make it right before you use it. It will start to harden after a little bit, so have the cakes all ready to frost BEFORE making the frosting, and it’ll spread just fine.

Substitutions

Using milk or nondairy milk

If you don’t have buttermilk you can substitute milk but you also need to add an acid or the baking soda won’t work. If you’re substituting milk, add 1 teaspoon of white vinegar or lemon juice to the milk; that will create buttermilk!

To use non-dairy milk, just make sure to add 1 tsp vinegar or lemon juice to the wet ingredients. This will create the chemical reaction needed to activate the baking soda.

Gluten Free Chocolate Cake

Yes! To make a gluten free chocolate cake, just substitute 1:1 gluten free all-purpose flour (my favorite is the light blue Bob’s Red Mill package).

Other Pan Sizes

I love that this cake recipe cane be used to make other size cakes and cupcakes.

Here are the best pan sizes for this cake:

  • Two 9-inch rounds (with tall 3-inch sides; that’s important!)
  • Three 8-inch rounds
  • 9×13-inch pan
  • 24 Cupcakes

Expert Tips

Baking soda and acid creates a chemical reaction. Remember that volcano from 3rd grade? It erupted right as you added the vinegar; same goes with baking. The baking soda chemical reaction begins right away and if you don’t bake it quickly enough, your cake won’t rise.

If a recipe calls for baking soda (especially a cake), it needs to be baked ASAP. There’s no wait-and-let-it-sit with this batter. Make it then bake it!

  • Measure your flour the right way.
  • Grease your cake pans properly for easy release.
  • Use the toothpick test for doneness, from the center of the cake.
  • Want an extra kick from the chocolate? Add 1 teaspoon of instant espresso or 1 tablespoon instant coffee to the hot water. You won’t taste the coffee flavor, but the coffee will bring out the chocolate flavor even more.

FAQ

How do you keep chocolate cake moist?

Make sure not to over bake the cake or it will be dry. This cake is super moist thanks to the baking soda and vinegar!

How to store chocolate cake?

Store the frosted cake loosely covered. You don’t have to chill it but you can, although the refrigerator can dry it out. Once it’s sliced I recommend storing it on the counter for up to 3 days.

Can you freeze a simple chocolate cake recipe?

You can freeze the layers before you assembling, just wrap them well in plastic wrap first. You can freeze the whole cake frozen but I don’t really recommend that unless you’re just freezing leftovers.

  1. You can always substitute plain kefir for buttermilk – in fact buttermilk is no longer the leftover from making butter, it is “cultured milk” aka kefir

  2. Made this cake last night and yes this is the first from scratch chocolate cake I have ever made as I prefer a white cake/frosting. So, I made this cake for my boss as his favorite is chocolate and I have to say it was very easy and oh my gosh….. SO delicious. The frosting is perfect in every way! I will not be making a boxed chocolate cake again.

    Also, I choose this recipe because your recipe for “better than doubletree chocolate chip cookies” are the truly best, so I knew the cake had to be good too! So thank you Dorothy!

  4. Will hot water cook the eggs? Should it be added before the wet ingredients?  I vowed to never make homemade chocolate cake again after a major disaster, but I am looking forward to trying this!

    2. No it shouldn’t cook them, as long as you’re adding all the ingredients together. Don’t let them sit in the hot water, but mix them all and it’ll be fine.
