Secret Ingredient Chocolate Cupcakes with Chocolate Sour Cream Frosting

secret ingredient chocolate cupcakes on overtime cook

A hundred years is a long time. I mean, I wouldn’t really know. I haven’t been alive long enough. Neither has my father. Or my grandfather.

But Hellmann’s is about to celebrate 100 years of business, and when they asked me to help them celebrate, I couldn’t say no. Firstly, like I said, 100 years is super cool. Also, I use one brand of mayonnaise and one brand only. Obviously, that’s Hellmann’s. And lastly, they are partnering up with Mario Batali, who I am a teensy bit obsessed with, (like, if one chef would cook me a kosher meal, I would probably pick him) to celebrate this milestone.

In honor of their big 100, Mario Batali recreated a number of Hellmann’s classic recipes. They asked me to put my own spin on one of Mario’s recipes. Well, there were a number of yummy looking options, but when I saw the chocolate cake, I immediately knew I had to create it. Firstly, I have long been intrigued by the concept of putting mayonnaise in sweet dishes. Also, chocolate.

Anyway, you know how I love mini’s, so I had to miniaturize this recipe! Instead of a layer cake, I made cupcakes. And while Mario Batali says he likes this topped with whipped cream, I couldn’t help myself. I had to dollop on some of this magical Chocolate Sour Cream Frosting. The only other change I made was swapping out the water for coffee. Because, uh, coffee.

Anyway, the result? Moist, chocolaty, deliciousness. The mayonnaise gives these cupcakes a fabulous and rich texture!

Before we get to the recipe, I want to let you know that Hellmann’s is offering all of you a chance to put your own spin on one of Mario Batali’s recipes…and win! Click here for all the details!

    Have you tried using this batter to make cake? If so what would the baking time be and what size pan would you use. Thank you. LOVE your blog!

    I haven’t made chocolate cake with mayonnaise before. I can just imagine how moist they would be. These look fantastic, Miriam, especially with that gorgeous frosting on top.

  3. Rochie says

    If I don’t have corn starch and I only have All Pupose flour, will that work ok, or is there something else I can substitute for the corn starch?

  4. says

    Wow! I’ve heard of mayonnaise in baked goods before but never thought it could look so good. These look awesome. Although, I must say I’m still a tiny bit scared/skeptical to try on my own. :)
