Wacky Cake Is The Easiest Chocolate Cake You’ll Ever Make!
No mixer, only a few simple ingredients, and a 9×13 pan and you’ll have a chocolate cake. It seems too good to be true, I know it does, but trust me on this! No eggs, dairy free…and did I mention you mix it right in the 9×13 pan you bake it in? I’ll explain it all, I promise!
What IS Wacky Cake?
This recipe is a major throw back. I found a version of this in my mom’s recipe box, and then after a quick google search, apparently everyone’s mom probably made this one too.
And here’s your history lesson for the day…
- It’s also known as Depression Cake and was created back in the Depression Era where ingredients were scarce and expensive.
- This cake is made without eggs or any dairy, which makes it lighter on the wallet, but also great for anyone who suffers from an egg or dairy allergy!
Of course I frosted it…and the frosting isn’t dairy free…but the cake itself absolutely is!

That’s Right, NO Mixer Needed!
Crazy, right? A cake without having to use a mixer? Or at least another bowl? It’s true. Pinky swear! A TRUE one-bowl cake!
When following my moms recipe I was a little skeptical about this…because not only do you use your cake pan as the mixing bowl, you don’t grease the pan. I certainly envisioned a huge cake fail…but alas, it worked.
Let me show you…

You Don’t Have To Grease The Pan!
I know it’s hard to believe. And yes, if you’re not convinced you can absolutely mix the ingredients in a separate bowl and coat the pan with nonstick spray. But the point is, you don’t HAVE to.
There is a tiny amount of sticking, but it’s a sheet cake and it really doesn’t matte, in my opinion!
Here are the simple steps:
- Sift the ingredients right into the ungreased pan. Sifting the ingredients together is the easiest way to combine them. I also whisked them together too.
- Make 3 “wells” in the dry mix. You pore vinegar in one, vanilla in another and oil in the last.
- Then pour water over everything and whisk it together to combine. I found online that using a fork here works well too.
- Once it’s all mixed, go ahead and bake!

What Kind Of Frosting Should You Use On Wacky Cake?
Wacky Cake is a chocolate cake, so there are TONS of frostings that work well here.
If you are trying to keep this dairy free, my buttercream frostings might not be the best option, but you can sub the butter out for a non-dairy butter substitute!

How does this work with no eggs and dairy and can you leave the cocoa out and make it a vanilla “wacky cake”?? lol
i might try that one next!!! great idea
Yes. Add a little more vanilla
This cake has been made over 70 years in my family! Slightly different measurements and we use regular vinegar. You can also mix it in a bowl and pour into pan. Comes out perfect every time!
I’ve never heard of this but it does sound incredibly cool! Thanks for sharing 🙂
My mom was never a baker; still isn’t, but we were raised on this cake!! I still love it to this day & make it on occasion. She would do a margarine (yuck, I know!), coconut, pecan topping on it that was really tasty & still made it dairy free!
The cake topping your mother used sounds just like the one used for German Sweet Chocolate Cake. I remember it well. Add that fact to my making the Wacky Cake years ago from a children’s cookbook from the 50s and I feel like I just took a trip down Memory Lane!
I grew up eating this cake. We never put frosting on it. We put butter. To me it would taste strange with frosting. I might try it.
Oh my word! Butter on cake?! That might be the most genius thing I have ever heard!
I’ve been making this cake for over forty years and my family loves it! I usually put 7minute frosting on it. Yum!
Hello! Looks really delicious! could you tell me please with what supplant apple cider vinegar? I really really hate vinegar.
You can’t taste the vinegar at all. It helps with the texture of the cake!
While the cake is still hot I place plain Hershey bars on the cake to melt then carefully spread to cover the entire cake. My sister just pours chocolate chips over the warm cake.
Great idea!!
I have been making this cake for over 40 years because of children with allergies. The cake is so good that it is often used for special occasions. So quick, so easy, so good!
Hi I have been using this recipe for a long time. Always a winner in my house and with the friends. I use a different frosting. 250 ml fresh cream, beat to stiff peaks, add 1 can of caramel treat and mix. Then add 3 tbs of cocoa power with and mix again. Spread over the cake. Try it and see how you like that. Greetings from South Africa.
I’ve made this for many years. My family an solute loves it with my homemade peanut butter icing, and it’s very moist.
Stephanie, please share your frosting recipe, if you could.
