If you’ve ever wanted a one-bowl dessert that feels fancy with minimal effort, this is it. Whether you’re baking for a birthday, a potluck, or just a Monday night treat, this cake never disappoints. With just pantry staples and a few minutes of mixing, you get a lush, soft crumb and a chocolate flavor that’s deeply satisfying.
Why You’ll Love This Chocolate Cake with Mayonnaise
This cake is incredibly simple to make, yet the results are outstanding. You won’t need any eggs or butter, and there’s no complicated creaming method. The mayonnaise provides the fat and structure for the cake, making it wonderfully fluffy and rich. Best of all, it’s nearly impossible to mess up. It’s a go-to for anyone who wants something impressive but easy.
What Kind of Mayonnaise Should I Use?
Use a good-quality full-fat mayonnaise for this recipe. Avoid low-fat or flavored varieties, as they can affect the texture and taste of the cake. Hellmann’s or Duke’s are excellent options. The mayo should be smooth and creamy to blend seamlessly into the batter.
Ingredients for the Chocolate Cake with Mayonnaise
Chocolate cake doesn’t need to be complicated to be delicious. This recipe proves that with just a few key pantry staples, you can create something magical.
- All-purpose flour: Forms the base of the cake and provides structure.
- Granulated sugar: Adds sweetness and helps keep the cake moist.
- Unsweetened cocoa powder: Gives the cake its rich, deep chocolate flavor.
- Baking soda: Helps the cake rise and stay fluffy.
- Salt: Balances the sweetness and enhances the cocoa.
- Mayonnaise: The star ingredient, adding moisture and replacing eggs and oil.

How To Make the Chocolate Cake with Mayonnaise
Step 1: Prep Your Oven
Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan or two 9-inch round cake pans.
Step 2: Combine the Dry Ingredients
In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking soda, and salt until evenly combined.
Step 3: Mix in the Wet Ingredients
Add the mayonnaise, vanilla extract, and water to the bowl. Mix with a whisk or electric mixer on medium speed until the batter is smooth and lump-free.
Step 4: Bake
Pour the batter into the prepared pan(s) and smooth the top. Bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean.
Step 5: Cool and Serve
Let the cake cool completely in the pan before slicing or frosting. This cake pairs beautifully with a classic chocolate buttercream or just a dusting of powdered sugar.
