One Bowl Chocolate Cake Recipe

Cook Time: 30 minutes

Skip the store-bought mix and make this one-bowl chocolate cake from scratch. It's almost as easy as the boxed stuff, but it's so much more delicious. The Allrecipes community agrees: You don't want to miss this simple chocolate cake recipe.

How to Make One-Bowl Chocolate Cake

It truly couldn't be easier to make this chocolate cake just combine the ingredients in a mixing bowl and bake! Here's a brief overview of the steps:

  1. Mix the dry ingredients in a large bowl.
  2. Mix in the eggs, vanilla, and oil on medium speed.
  3. Stir in the boiling water.
  4. Pour the batter into prepared pans.
  5. Bake until a toothpick comes out clean.

Step 1: Prepare the Dry Ingredients

In a large mixing bowl, combine the sugar, flour, cocoa powder, baking powder, baking soda, and salt. Stir well to ensure everything is evenly mixed.

Step 2: Add the Wet Ingredients

Add the eggs, milk, vegetable oil, and vanilla extract to the dry ingredients. Mix on medium speed with an electric mixer for about 2 minutes until the batter becomes smooth and well-combined.

Step 3: Incorporate the Boiling Water

Now, carefully stir in the boiling water. The batter will be quite thin, but this is perfectly normal and will give the cake its moist texture.

Step 4: Bake the Cake

Pour the thin batter evenly into the prepared 9-inch round cake pans. Place the pans in the preheated oven and bake for about 30 to 35 minutes. To check if the cake is done, insert a toothpick into the center if it comes out clean, the cake is ready!

Step 5: Cool the Cake

Allow the cake to cool in the pans for 10 minutes before transferring it to a wire rack to cool completely.

Best Frosting for Chocolate Cake

When it comes to frosting, you have plenty of options. One of our favorites is the top-rated Creamy Chocolate Frosting, which comes together quickly and uses ingredients you likely already have. If you prefer classic options, try cream cheese frosting or a buttery buttercream. For a fun twist, consider a Fluffy Peanut Butter Frosting for a decadent flavor pairing.

How to Store Chocolate Cake

The best way to store your chocolate cake depends on the frosting you use. A buttercream-frosted cake can sit at room temperature for up to five days, as long as it's covered. If you use cream cheese frosting, refrigerate it within two hours of baking.

Can You Freeze Chocolate Cake?

Yes, this cake can be frozen! For the best results, freeze the individual, unfrosted layers. Wrap the cooled layers tightly in plastic wrap, then cover them with aluminum foil labeled with the date. To keep the cake well-protected, place the wrapped layers in an airtight . Freeze for up to three months, and thaw overnight in the refrigerator before serving.

I found that this recipe is quite similar to "Black Magic Cake," which I personally prefer. The cake turned out to be not as dense or fudgy as this one, with just slight variations. While this cake is deep and rich in chocolate flavor, I felt that it was overly moist and dense for my liking. It's hard to pinpoint the exact reason for the difference since the recipes are almost identical, so it might just come down to personal preference. Although this cake was good, I think I'll stick with the other recipe moving forward.

Wonderful recipe that was simple to follow and a hit with the kids! I made a few adjustments - used 1/2 cup of boiling water instead of a full cup, reduced sugar to 1 cup instead of 2, and baked it for 40 minutes in a large round pan. My family enjoys desserts that are less sweet, and this turned out to be a deliciously rich and moist chocolate treat. It has quickly become a new family favorite! Thank you!

I swapped out black coffee with boiling water, let the cake pans sit overnight, and then removed the cakes. I used 6-inch pans and ended up with two cakes (three layers each) using this recipe. I also mixed black cocoa (1/3) with regular cocoa (2/3). The cake isn't overly sweet, but it is incredibly moist and delicious - probably the best cake I've ever baked. This recipe is definitely a keeper!

I substituted 2/3 cup of agave for each cup of sugar in this recipe. I mixed agave into cocoa and cooked it over heat until it became syrupy. Then, I poured the mixture into a square pan. The final result was a moist cake that wasn't overly sweet but had a delightful taste. I topped it with slivered almonds this time, but I'm thinking of using pecans next. Overall, this cake is absolutely delicious!
