RAN THE OTHER WAY.
I know these cupcakes sound crazy, but they are also crazy good. The unexpected secret ingredient keeps them soft, light, and super fudgey, without any added oil. They taste almost like a brownie in the shape of a cupcake, and they’re so rich they don’t even need any frosting!

Using mayonnaise to add depth and flavor to cakes is hardly a new concept. The idea is much older than me, and it’s probably older than most of you as well. Also known as Wacky Cakes or Chocolate Depression Cakes, the origin of mayonnaise cakes can be traced back to the Great Depression, when ingredients such as butter, eggs, and milk were scarce, which forced bakers to get creative.
Today I’m posting a healthier cupcake adaptation of my grandmother’s popular Wacky Cake recipe. (Her version of the classic cake is most likely similar to other versions you’ll find either online or passed down from generation to generation in your own families.)
I’ve played around with the original recipe’s ingredient proportions in order to cut back on the sugar while still maintaining a delicate and fluffy texture—these rich and decadent cupcakes turned out so much better than I’d even hoped.
Instead of frosting, I topped them with Healthy Nutella.
They’re also delicious without any frosting at all!

Why the recipe works:
Vinegar reacts with the baking soda, which forms bubbles and thus makes the cupcakes rise, without needing any eggs. Just be sure to follow the recipe instructions and bake immediately after pouring wet into dry, as the vinegar reaction begins as soon as the two ingredients meet. You’ll find vinegar in many of my recipes, such as Eggy Breakfast Bread or the Chocolate-Chip Biscuits, as it’s a trick I often employ for light, fluffy baked goods.
In this particular recipe, the vinegar present in the mayonnaise is what reacts with the baking soda. I can vouch for the recipe working with Vegenaise (low-fat or regular) as well as Earth Balance Mindful Mayo. If you want to use a homemade mayo-type spread: although I can’t vouch for every single homemade mayo spread out there, it should work as long as your mayo spread includes vinegar (or lemon juice) and a fat source such as oil or cashews. If you are using a homemade mayo-type spread, I highly recommend omitting any onion powder and mustard that might be called for in your recipe!

 Chocolate Mayonnaise Cupcakes
(or Devil’s Food Cupcakes)
- 1/2 cup spelt or all-purpose flour (65g) (Arrowhead Mills gf also works.)
- 3 tbsp cocoa powder (15g) (not Dutch)
- 1/4 tsp baking soda
- 1/4 tsp salt
- 1/2 cup xylitol or sugar of choice (90g)
- 1/4 cup mayo-style spread, such as Vegenaise (See above paragraph for other brands that work.) (58g)
- 1 1/2 tsp pure vanilla extract
- 1/3 cup plus 1 tbsp water (95g)
Preheat oven to 350 F and place 6 cupcake liners inside a muffin pan. In a large bowl, combine first five ingredients and sift very well. In a separate bowl, combine remaining three ingredients and whisk until the mayo is completely smooth. Now pour wet into dry and stir until just combined. Immediately divide among the cupcake liners—it won’t seem like a lot of filling, but these cupcakes rise a lot! Bake 21 minutes, then let sit 15 minutes before removing from the pan. These taste ten times more fudgey and rich the next day, so bake the day before eating if possible. Store in the fridge. (Cupcakes in the photos are frosted with my healthy Nutella recipe linked below the second photo on this page.)

Are you brave enough to try them?
Or have you ever tried using mayonnaise in baked goods before? Honestly, I think this might be the best cupcake I’ve ever eaten!
Link of the Day:
…….Vanilla Chai Breakfast Shake

















If I am going to use a GF flour w/o xanthan gum, should I add it separately? I primarily use Pamela’s just because that’s what I have around… I could use the baking mix (which is probably more similar to the Arrowhead mills because it already contains xanthan gum) or the Artisian flour blend (no xanthan gum). Thoughts?
You will have to experiment!
These were pretty damn good! My boyfriend demanded mayonnaise cupcakes with sour cream frosting (this is like my nightmare) but they were super decadent and really chocolatey! Thanks for the recipe.
Can almond flour be used in place of spelt flour?
Hi Katie!
Love your recipes! My sister has this idea that I’m a really good baker now because of them so thank you! She’s in grade school and she’s been going to fish fry’s during this lent and yesterday was the day she brought home a baked good. It was bound to happen sometime. She brought home chocolate cupcakes. She and I were talking and now we’re slated to bake cupcakes together for next friday’s Fish Fry. I’ve been looking at a ton of recipes and this is one that I’d like to try, but I was wondering where you buy your Vegenaise? From my research, it’s not too different from regular Mayo, but if it’s near by at Rainbow Blossom, Krogers, or Whole Foods, I’d love to try it! Thanks.
I’m sure I’ve made cake with mayo before, I will definitely try these, they look great 🙂
Omg just made these they are delicious & my girls love them too
You are right..this is the best cupcake ever. Its taste is fudgey moist. But…(!).they are falling apart. I dont know how well the icing will go on. It may be because of the changes i made. this is the fourth recipe ive made from this site, and i usualy double them all, and that sometimes means trouble. I also didnt have any baking soda, so replaced it with 2 teaspoons of baking powder. Would this be the reason for the crumbly texture?? I dont find they rose as.much as i thought they would…anyways..i will def. Try them again…soooo good.
Just made the Mayo Cupcakes. They are incredible! My husband hates all healthy desserts and he loves these!
OMG. These cupcakes are delicious. I made them this afternoon, with low-fat Vegenaise, and had one still warm out of the oven. Seriously, this are great. Also, thank you for having gram measurements for your ingredients! I recently got a kitchen scale, and I love using it with your recipes!
Why not dutch cocoa? Does it react badly with the vinegar?
