The Secret Ingredient of this Moist Chocolate Cake
People are always surprised by this chocolate cake's secret ingredient. Are you ready for this?
It's mayonnaise. Yep. A bit of mayo incorporated into this recipe makes it extra moist. I know it seems a little unusual, but trust me, it makes for a DELICIOUS cake.
Don't worry, the mayonnaise is completely undetectable, but the resulting ultra moist crumb elevates this chocolate cake to a new level of deliciousness. You'll be tempted to throw a bit of mayo into every cake mix recipe (and maybe you should!)
This Recipe Makes Delicious Chocolate Cupcakes Too!
Whenever I need delicious chocolate cupcakes from a mix, I use this recipe. The cupcakes are so moist and chocolatey, but have a satisfying fluffiness too. Everyone loves them! We hope that you enjoy this quick, easy, and delicious recipe!
Working with fondant? Read this first!
***This is a very moist cake and softer than most of the cakes in our Recipes section. I wouldn't advise covering this cake with fondant unless you dam and frost your layers with a chocolate ganache frosting (like our Simple Spreadable Ganache frosting). Once the ganache has firmed up, it provides a sturdy shell to properly support the weight of the fondant.
Every Chocolate Cake Deserves a wonderful Chocolate Frosting!
The chocolate cake pictured above was frosted with our favorite Classic Chocolate Buttercream Frosting recipe. We piped the spirals of buttercream with a star tip 21.

Don't even think about canned frosting, this chocolate buttercream recipe is SO easy to make and tastes a million times better than anything that you can find at the store! Yummmm....
How to Make a Doctored Cake Mix Chocolate Cake
- Okay, so nobody has to know how simple this cake is to make. It'll be our little secret. We've gotten SO many rave reviews for it, and it comes together in minutes!
- First, grab your favorite boxed chocolate cake mix. (We've flip flopped over the years and currently use Duncan Hines.)
- Sift your cake mix into your mixing bowl. This step is surprisingly effective in improving the texture of your cake! Plus, every once in a while you'll find a granule of something or other that doesn't belong in your batter ;0)
- Add your ingredients as listed on the box, plus vanilla, cocoa for a little added richness, and our magical mayo that's going to make the cake extra moist.
- Mix for two minutes and pour the luscious batter into your prepared pans.
How to Make Your Cakes even more Moist...
Here's a cake Pro Tip for you! Another secret to an ultra moist cake happens AFTER baking. Once you remove the cakes from the oven, allow the layers to cool in the pan on a wire rack for about 10-15 minutes.
Then, flip out the warm layers and wrap individually with plastic wrap, then foil. Place in the freezer. (It's up to you if you want to place them on a foil-wrapped cake board for extra support while in your freezer- we often do this)
When you are ready to thaw and decorate, remove the layers from the freezer and place on your kitchen counter to begin to thaw.
Once condensation begins to form on the foil (10-15 minutes), you can remove the wrapping and thaw to desired temperature. (Sometimes its easier to assemble, fill, and crumb coat a cake while it's still partially frozen but that is up to you!)

Chocolate Cake- A Doctored Cake Mix Recipe
This moist and delicious Chocolate Cake all starts with a simple cake mix and a secret ingredient or two! Nobody would guess that this amazing chocolate cake isn't from scratch! So good!
Ingredients
- 1 box Chocolate or Devil's Food Cake Mix ( we usually use Duncan Hines cake mix)
- Ingredients as listed on the box (water, eggs, and oil)
- 1 Tablespoon cocoa powder
- 1 teaspoon vanilla
- 2 rounded Tablespoons mayonnaise (Use full fat. We like Hellman's.)
Instructions
- Sift mix into bowl and add ingredients according to box instructions. Add vanilla, mayo and cocoa.
- Mix all ingredients on medium speed for two minutes, scraping the bowl when necessary.
- Oven should be pre heated to 325 degrees. Fill two eight inch cake pans that have been greased and floured. Bake at 325 degrees for 25 to 30 minutes. When a toothpick is inserted in the center and comes out clean or with just a few crumbs attached it is done.
- This is optional but your cake will be more moist if you wrap your warm cakes in plastic wrap and aluminum foil and freeze for at least 2 hours. If you are baking in advance the cake layers can be frozen for 2 months. Just make sure they are wrapped air tight. Thaw on the countertop when ready to use.
- MAKES GREAT CUPCAKES - Fill cupcake liners ⅔'s full and bake at 350 degrees for 18 to 20 minutes.

Thanks for posting this tip, Robynne.
Will this cake work with fondant decorations such as roses? I'm making a graduation 3 tier cake (12, 9 and 6) all buttercream except the decor. There will also be a grad hat on the top, supported with dowels. Or do you recommend your chocolate wasc instead? Thanks so much!!
Hi Coreen, If you have already made the cake layers using the above recipe, it will be fine to use. However, when making a tiered cake using a doctored recipe we prefer using the Chocolate WASC because it is a bit more dense.
Will I be able to use whole milk and butter in place of the oil and water as the box directs? Just not sure with the addition of mayo and cocoa if I can still do that, thanks :) :) :)
Hi Chelsea, If you typically use whole milk and butter in your boxed cake recipes, I think it will be fine to add the mayonnaise and cocoa.
This cake looks great. Can I use sour cream in place of the mayo? I do not buy it as my family is anti-mayo.
Hi Karen, We have not used sour cream with this recipe, though I think it would be fine to do so. The mayo adds moisture to the cake. Melissa also has another doctored chocolate cake recipe that does use sour cream, here is a link if you would like to check it out https://www.mycakeschool.com/recipes-tutorials/chocolate-sour-cream-cake/
I see your white cake recipe has been updated but not this one. Is this for the 15 or 18 oz mix? If so need to know if needing to add additional mix or flour? TIA
I like to doctor my cakes up also. I use an equal amount of melted butter in place of the oil and I use milk in place of the water. I do this on ALL cake mixes, I then do some flavor specific things, like I also add 1/2 teaspoon of Almond flavoring in Chocolate cake. I do add the cocoa, occasionally a touch of cinnamon also. I will do the addition of the mayo and give that a try. If I have buttermilk I always use that rather than plain milk.
Fajowa stronka!
Hi Bebe, thi recipe is not recommended to covered with fondant, can I put on top a litlle logo with 37 gramas of fondant. And this cake can be refrigerated for how many time with out risk to this logo
Hi Dalila, Yes, a small logo on top should be fine. We have refrigerated Satin Ice Fondant and also the Liz Merck Fondant recipe with no problem. You could test the fondant by putting a small piece in your refrigerator and see how it holds up. It should be fine for 2 days. If possible, you could also add the logo just before the cake is served.
