This recipe for Chocolate Mayonnaise Cake makes a beautiful, tender, light-textured cake that’s incredibly moist and indulgent.
Being a food blogger, I often have friends that like to surprise me with their bakes. One of my friends made a delicious chocolate cake and proudly asked me to guess the secret ingredient. When she announced, mayonnaise, I must admit I was pretty amazed. I quickly got to work on creating my own version of her delicious cake.
Why This Recipe Works
- Mayonnaise adds richness and moisture to this incredible cake.
- Using coffee compliments the chocolate and gives an extra depth of flavor.
- Buttermilk helps give the cake extra moisture and sublte tangy taste.
Using Mayonnaise In Cake
Being made mainly made of eggs, vinegar, and oil, mayonnaise adds extra moisture, and rich flavor to cakes and produces a light tender crumb.
This cake has a deep chocolatey flavor that pairs perfectly with my Chocolate Glaze that’s smooth and creamy without being too sweet.
Ingredients Notes
- Flour– Use all-purpose (plain) flour. I recommend a good quality unbleached all-purpose flour with 4-5g of protein).
- Baking Powder & Baking Soda be sure to check the date on your package as out-of-date products may not add the lift you need.
- Cocoa Powder– I use unsweetened Dutch-processed cocoa powder, but any unsweetened variety will do.
- Sugar– this recipe calls for granulated sugar to keep things simple, but I use superfine sugar (aka caster sugar) because I like the way it easily mixes into the batter.
- Mayonnaise – Full-fat mayonnaise is essential for moisture in this recipe as it’s replacing any other fats in the cake such as butter or oil.
- Eggs – Use large eggs.
- Buttermilk– I’ve full or reduced-fat buttermilk in this recipe with the same result.
- Coffee – I used strong, brewed coffee, but you can instant coffee or espresso powder to make yours. The stronger the coffee, the more it enhances the flavor of the chocolate.
- Vanilla Extract: You can use anything from imitation vanilla flavor to pure vanilla extract or vanilla bean paste.
- Salt: Regular table salt is fine to add seasoning and enhance the flavors.
How To Make Your Own Buttermilk
To make your own buttermilk at home, add 1 tablespoon of white vinegar or lemon juice to 1 cup of milk. Full-fat milk is best, low-fat or skimmed milk will still work. Stir and let stand for 5 minutes. The mixture may look a little curdled, but that’s fine.
For this recipe: 1 cup of butter milk = 1 tablespoon of vinegar or lemon juice.
How to Make Chocolate Mayonnaise Cake

- Combine wet ingredients and mix well.
- Stir the wet mixture and dry mixture together along with coffee.

- Serve and enjoy!
Step by Step Instructions

In a separate bowl add mayonnaise, eggs, buttermilk, and vanilla. Then add the cup of coffee.
Add the wet ingredients into the dry.
Mix until combined.
Add to the greased pan.
For this cake, I used the Nordic Ware Anniversary Bundt Pan which you can get at Amazon. (#paidlink).
Bake and allow the cake to cool on a wire rack.
Glaze before serving if desired (I used my chocolate glaze recipe).
Serve and enjoy!
Erren’s Top Tips
- To avoid the cake sticking to the pan, use a good quality, non-stick pan that’s greased well with baking spray or shortening (butter can cause sticking).
- Always use full-fat mayonnaise, low fat and light mayonnaise will not provide the moisture you need.
- Be sure to follow the steps of the recipe. Mixing the wet and dry ingredients separately before combining them helps to avoid overmixing.
- Try to use the best quality cocoa powder you can find. It really makes a huge difference to the flavor of your cake.
Storing & Freezing Instructions
Storage – Store covered at room temperature for up to three days.
Freezing Instructions: Freeze the cooled, unfrosted cake wrapped well for up to 3 months.

Annie says
I’ve never used coffee in a recipe before so I want to make sure I am understanding this correctly. Can I use a cup of brewed coffee?
Erren Hart says
Hi Annie, I’m so glad you asked! I updated the recipe to say brewed coffee. A cup of instant coffee would have been a disaster! Thank you for pointing out that it could be confusing!

Mercy says
I would really love to try your recipe. Im just confuse about the coffee. I mean, how much coffee powder should you put in a cup of hot water.? Thanks. Waiting for your answer…
Erren Hart says
If you’re using instant coffee, add a heaping teaspoon to the water, but be sure to allow it to cool enough before adding it to the batter or you can risk cooking the eggs.
Jill Wilson says
How does this cake do when chilled? Some chocolate cakes get super crumbly when cold…does this one? Thank you!!
Erren Hart says
Hi Jill, You’re right that some cakes can dry or crumbly when refrigerated. This is because the cold temperature can cause the moisture in the cake to evaporate more quickly, leading to a drier texture. Chocolate cakes are particularly susceptible to drying out, as the cocoa powder and sugar can absorb moisture and make the cake more brittle. However, the mayonnaise in the Chocolate mayonnaise cake recipe helps to add moisture and structure to the cake, which can slow down the process of becoming too dry or crumbly when chilled, but all cakes will dry out when chilled. Nonetheless, bringing the cake to room temperature before serving is always a good idea, as this can help restore its texture and flavor. I hope that helps clarify things, and please let me know if you have any further questions!
