Crazy Chocolate Cake

This crazy cake is made without butter, eggs or a mixing bowl. All you need are some pantry staples, which are mixed directly in your baking pan. The result is a deliciously moist and tender made-from-scratch chocolate sheet cake. This is such an easy and quick cake to make.

I recently stumbled upon the concept of crazy cakes and of course I was intrigued and had to try it out for myself. This recipe seems particularly fitting now, since this cake can be made with just a few pantry staples.

What is Crazy Cake?

Crazy cake, sometimes referred to as wacky cake is a cake that was created during World War II rationing, when ingredients like eggs and milk were scarce. I’ve also made an Italian water cake, which is the same concept – no eggs, butter or milk required.

All the ingredients are added directly to the baking pan and mixed before going into the oven to bake. The cake bakes up much like a traditional cake, with a tender and moist crumb.

Crazy Cake Taste and Texture

The cake tastes very much like a traditional chocolate sheet cake, though a little bit less rich. The cake reminded me a lot of my chocolate cake mix mug cake, which is not a huge surprise since that is also a cake made without eggs or dairy.

How to Make Crazy Cake

The process for making crazy cake reminds me of the dump cake recipes I’ve shared.

  • First, you add all the dry ingredients directly into your pan and whisk them together.
  • Then you make a few wells in your dry batter to pour in the wet ingredients.
  • Everything is then whisked together until your batter is smooth and evenly combined. The cake is then ready to go in the oven.

Ingredients

  • 1 1/2 cups all-purpose flour
  • 1/3 cup unsweetened cocoa powder
  • 1 cup granulated white sugar
  • 1 tsp baking soda
  • 1/2 tsp table salt
  • 1 tsp white vinegar
  • 1 tsp vanilla
  • 1/3 cup olive, vegetable, or canola oil
  • 1 cup water

Chocolate Ganache Frosting (optional, not dairy-free)

  • 4 oz heavy cream
  • 4 oz semi-sweet chocolate finely chopped

Instructions

  • Preheat oven to 350°F. Line an 8 inch x 8 inch baking pan with parchment paper.
  • Add flour, cocoa powder, sugar, baking soda, and salt directly into baking pan. Whisk together until evenly combined.
  • Make two small wells and 1 large well in the dry ingredients. Add vanilla to one small well and vinegar to the other small well. Add oil to the large well. Pour the water over the top and whisk everything until batter becomes smooth and evenly combined.
  • Place cake into oven and bake for about 35 minutes or until a toothpick inserted comes out clean. Let cake cool completely before frosting. You can top with your favorite chocolate frosting, powdered sugar, or chocolate ganache.
  • To make chocolate ganache: Add chopped chocolate to a medium bowl. Bring heavy cream to a simmer on the stove. Pour heated heavy cream over chopped chocolate and immediately start to mix until the chocolate is completely melted and smooth. Let chocolate ganache cool at room temperature or in the fridge until it becomes firm enough for frosting the cake.

Notes

  • Recipe from Barefeet in the Kitchen.
  • If your cocoa powder has clumped up due to moisture, break up the clumps before adding it to the baking pan.
  • Do not leave out the vinegar. It is used to activate the baking soda.
  • The recipe can be doubled and baked in a 9 x 13 inch baking pan. Baking time should be about the same and should not be doubled.
  • Estimated nutrition does not include frosting.

  1. I’ve been making this cake since I was in college in the early ’70s (found it in Peg Bracken’s “I hate to cook” book).

    One time I was out of cocoa powder but had a box of instant cocoa mix, the kind that you make with just hot water. So I used that in place of the unsweetened cocoa, doing a bit of math to figure out how much of each packet was sugar (look at the nutrition info on the cocoa mix label, every 12.5 grams of of added sugar is a tablespoon of sugar) and how much was cocoa so I’d know how many packets to use and to figure out if I needed to add more sugar. I worried that the dry milk powder in the mix would change the flavor, it did, but it made it even better, like a sour cream chocolate cake.

  2. How long does this cake keep for if stored in a cake tin please?

    • It will keep for a few days at room temperature or you can keep it in the refrigerator for a few days longer. Be sure to cover it tightly with plastic wrap.

  3. This was really helpful for me

  4. Can you substitute applesauce instead of using
    Oil in the recipe,
    Thanks!

  5. i would like to try your crazy cake but i am diabetic do you have a no sugar version that could work for me please and thanks

  6. I’ve made ganache using a can of coconut milk removed from the fridge and only using the cream part on top, not the clear fat on the bottom of the can. Add the chocolate and whip after melting then let cool. I’m so happy to have found this recipe. Your site is awesome. Can’t wait to make it!

  7. “Crazy Cake” is an old recipe, known as “Whacky Cake”, and is in many cookbooks.
    Great cake I make it often and everyone loves it!!

  8. Would this recipe work ok in a round tin?

  9. Very difficult to make wells with lined parchment paper in a 8×8 baking pan.

  10. This sounds great. I am raising a child who is allergic to cow’smilk, peanut, wheat, egg and soy. This post gives me hope that there could be something out there i could whip up for him. Is there anything i could use to substitute wheat flour?

  11. I made Crazy Cake for many years, but totally forgot about it as I don’t bake much anymore. It is the most delicious chocolate cake ever. I would frost with creamy white frosting, but any frosting or none at all works. I now look forward, once again, in surprising my husband with this great dessert. Serve with ice cream too.

  12. I’m going to try making the recipe sometime soon. Your advice please; ok to add (say) chopped walnuts or chopped dates?

    I hope you dont mind –  its not my intention to bastardise your beautiful recipes; on the contrary, I find them very inspirational!

    • We haven’t tried adding mix-ins to the batter, but if you do it’s probably a good idea to finely chop them since the cake is delicate.

  13. That’s incredible

  14. I made the crazy chocolate cake and forgot the oil! No problem as it turned out, husband stated best chocolate cake he’d ever tasted. I also thought it was delicious. Bit high in calories, half portion eaten.
