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:

  1. 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.
  2. Make 3 “wells” in the dry mix. You pore vinegar in one, vanilla in another and oil in the last.
  3. Then pour water over everything and whisk it together to combine. I found online that using a fork here works well too.
  4. 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!

  1. I will make this and share it with all my family and see what they think. I have been making a Wacky Cake for over 50 years. It was from my Dads side of family. And We liked it very much. It had a few different items in it.






  2. I’ve made chocolate and white wacky cakes …we call this cake..chocolate peanut butter icing, the family bday cake hahah…anyway, I will make black walnut cakes with this minus the chocolate. I’m out of flour..gasp!..but have a box cake. Can I make the box cake like the wacky cake..I live how heavy the wacky cake is!

  3. This was the first time I made this cake so very very easy good flavor. and my house smells great.thank you for sharing.






  4. Had this at a friend’s house tonight and oh my! We had it warm with a simple raspberry glaze and vanilla ice cream. It was soooo good!






  5. I have been making this cake for at least 40 years. It always turns out great, and there are very seldom leftovers. I have made many different types of frosting, but our favorite is chocolate/peanut butter. I put in about 1/3 cup cocoa in a bowl, along with 1/4 cup butter. I put it in the microwave for about 30 seconds, or long enough to melt the butter, then stir. It gives the frosting a darker brown color. I then add 1/2 cup peanut butter, vanilla, and cream it all together. Then start adding powdered sugar and a little milk until you get the consistency you like. I use non-dairy creamer instead of milk when my grandchildren are there as they are lactose intolerant. Delish!






  6. Easier than a cake mix. Seriously. And delicious. I submitted it as a vegan entry in a work bake-off with a vegan buttercream and won. Even the vegans didn’t believe it was vegan.






  7. I love wacky cake and am very excited to make this! Do you think it’s sturdy enough to layer 2 9x13s for a larger sheet cake? Thanks!
