Can you really go wrong with this Old School Super-Moist Chocolate Cake with Chocolate Buttercream Frosting for any occasion? You'll want to serve this up, trust me! Besides, there's a secret in this chocolate cake that makes it super-ultra-moist.
Can you try to guess what it is?
Mayonnaise! Yes, I really said 'Mayonnaise'!
ChocolaTess Trivia! Chop!Chop! Quick history lesson today, because it's interesting to find out new facts, right? Then you can pay it forward. 🙂
Chocolate Mayonnaise Cake was a Depression-era (1929-39) dessert that was made popular by Best Foods/Hellmann's to promote their delicious mayonnaise and it also provided as an economic substitution for butter and milk and most notably, for sour cream, sour milk and buttermilk as well, which were very popular at the time.
It's an old cat-in-the-hat baking trick that's been around longer than cake mixes.
Speaking of cake mixes, did you know you can substitute mayonnaise for the the oil and eggs in a cake mix? You can! You can get more info on that over at Duncan Hines. They would know! 🙂 The fact of the matter is, this mayonnaise cake is fudgey, rich, moist, and a true classic chocolate dessert that tastes out of this world AMAZING!
Mayonnaise is essentially oil, vinegar, and egg, and while you could just add an extra egg to try and get the same effect, The Kitchn points out that the oil makes the cake tender, the egg helps the batter retain moisture, and the acid in the vinegar really brings out the chocolate flavor.
If you don't like mayonnaise
The chocolate buttercream...OH EM GEE! Perfect pairing with this cake!
I doooo love this cake and frosting and it's been such a classic cake over-time! And it always will be! *swoon*
I got this recipe from A Bountiful Kitchen and it's wonderful!

Hi Kristen! Yes I do and it would give it a richer chocolate taste as well! xo Sounds super yummy!
Hi there! I would like to make this for a wedding that I am planning. Do you think I could substitute the boiling water for coffee?
Rissa, I would have loved to taste her baked goods! YUM! Sounds like an amazing woman and baker. I love the old retro desserts and their secrets!! Thank you so much for your kind words! xo
Really love your recipes. My mom always made what she simply called a mayonnaise cake and she was the best baker in the world. She would make 15 pies at a time for our church bake sales. That’s how it was back in the day. Everything homemade. So I was glad to see your recipe for mayonnaise cake. Nice to see some of the old ingredients making a come back.
Mimo, not sure what percentage you are using, but if you do, I would taste the batter after it's done and see how it tastes before baking. It should be more like milk chocolate instead. Good luck!
Hi I want to try the cake just wanted to ask what happens if I use chocolate with more than 61%cacao thanks
Virginia it should below the last picture of cake @ http://www.thebakingchocolatess.com/super-moist-chocolate-cake-with-chocolate-buttercream-frosting/. You should be able to print it, but here it is as well.

Where can I find directions. Keep going back to comments.
Hi Pam! Happy Birthday to you and your husband! 🙂 So, I was reading your comment and I did want to let you know that I did only use 1/4 teaspoon baking powder. If you add too much baking powder, it will taste bitter and it will affect the cake by making the cake rise up too fast, causing air pockets to rupture and collapse, delivering a denser, squatter cake. I wonder if this might be the problem?
Made this cake for my husband and my birthday (we are 2 days apart)...
When reading directions, seems there is not enough baking powder in it...1/4 tespoon only?? I added 1 teaspoon! It rose up beautifully....
Also, I had to bake it just 5 minutes longer...
Been making a mayo cake with a boxed cake for 40 years....the scratch ones never interested me until this one...
Has anyone else found it to be a heavy dense cake??? Or did I do something wrong..followed directions to a tee and have been baking 50 plus years.
Thanks

Hi Lynn! Fill the cupcake liners about three-quarters full. Bake the cupcakes for 17 to 20 minutes, rotating the pans halfway through the baking time, until a toothpick inserted in the center of a cupcake comes out clean. ?Makes 24 cupcakes. Enjoy!!
Hi! I making a cake but also want to make cupcakes for a party. Any idea how many this recipe would make and how long to cook?
Thanks!
Hi Amanda! Fill the cupcake liners about three-quarters full. Bake the cupcakes for 17 to 20 minutes, rotating the pans halfway through the baking time, until a toothpick inserted in the center of a cupcake comes out clean. 🙂 Enjoy!!
I am wanting to make cupcakes. Should I adjust the temp or time on these for a cupcake pan?
I'm happy I could bring those special memories back for you! 🙂 Thank you so much for sharing!
My mother used to make what she called chocolate mayonnaise cake when i was growing up back in the 70's. I thought everyone used mayonnaise in their chocolate cakes? I remember mentioning it once and my husbands family thought i was crazy. Glad you are bringing it back! It makes the best cake i have ever had! Thank you for sharing and bringing back good memories for me!
Thank you Lucy!! 🙂

Happy Baking and let me know if you have another questions! 🙂
How long do you bake the cake and at what temp?? Also what size pans are you using?? Thank you
Yes, 1 cup. I'm so sorry that happened to you Wendy! I haven't heard of anyone else having that issue, so it must be something weird going on for you...ugh! 🙁 But thanks for letting me know.
This is what I see:
Super-Moist Chocolate Cake
2 ounces bittersweet chocolate (do not exceed 61% cacao), chopped
1 cup unsweetened Hershey's Special Dark Cocoa Powder (or regular unsweetened cocoa powder)
1 3/4 cups boiling water
2 3/4 cups all purpose flour
1 1/4 teaspoons baking soda
1/4 teaspoon baking powder
1 cup sugar
1 cup (packed) dark brown sugar
1 1/3 cups mayonnaise (do not use reduced-fat,fat-free or Miracle Whip) Hellman’s
2 large eggs, room temperature
2 teaspoon vanilla extract
Chocolate Buttercream Frosting
1 1/4 cups butter, softened
4 1/2 cups powdered sugar
3/4 to 1 cup unsweetened cocoa powder (for dark frosting, use part Hershey’s Special Dark Cocoa, about 4 tablespoons)
2 teaspoons vanilla
1/4 cup plus 2 tablespoons milk or heavy cream
It's not showing a second sugar for me. I found a similar recipe on line and added sugar. I would upload a photo to show but that's not an option. I added a cup of white sugar- is that what is listed on this recipe? It must be loading weird on my end.
Wendy, I do have both sugars listed in the recipe.
Krista, it does seem strange, but it's delish! Just make sure you don't use Miracle whip, because that will make it too sweet. 🙂 Hope you enjoy!
It says best both sugars with mayo and add eggs. There's only brown sugar listed in the ingredients. Sure wish i had noticed that because I'm making this right this minute. Lovely.
I have never heard of using mayonaise in a cake but I will defiently be trying this. Thanks for the recipe.
Awww! Thank you Maria! Definitely give it a try!! 🙂
Drooling over this cake! I've read about the mayo chocolate cake many many times, but never made it! This cake is so happening....
🙂 Pretty awesome huh?!
Would have never thought to substitute anything baking with mayonnaise!
Thank you Kelly!! It's an awesome secret ingredient! 🙂
Love this!! Chocolate overload! And the mayonnaise is the best secret ingredient ever!
