Classic Chocolate wacky cake baked in a 9x13 pan, looks very dark and chocolatey.

Chocolate wacky cake is one of the best dessert recipes to have in your recipe collection. It’s nut free, egg free, and dairy free and super easy to make.

Because chocolate wacky cake is such a no-fuss recipe, it’s my go to recipe when I need a dessert in a hurry. I have probably made hundreds of orange chiffon cakes in my youth. When I saw that I could mix wacky cake ingredients in a 9×9 baking dish and bake the batter in the same dish, I love the simplicity of making a chocolate cake that tastes delicious.

Update (2/2/2023): This post has been updated with minor edits. Also please note that since I originally shared this recipe, Rodelle’s cocoa products now have the following allergen advisory: Produced in a facility that processes milk, wheat, soy, eggs, sesame, almonds and coconut. Contact us for allergen questions.

I took a quick photo of this wacky cake baked in a 9×13 pan for another recipe I was making. Note how dark and chocolatey the cake is. It’s also super moist and tastes wonderful the next day.

Nut Free, Egg Free, Dairy Free Chocolate Wacky Cake

I learned that chocolate wacky cake was invented during the depression era (1930s) and uses the most basic baking ingredients. At the same time, chocolate wacky cake happens to be nut free, milk free, and egg free. My son who is allergic to eggs doesn’t like chocolate so I make a lemon cake which we all love as an alternative flavor.

I have baked a lot of nut free and egg free desserts and birthday cakes for my kids over the years. And because some of their friends are also allergic to milk, wacky cakes are a perfect base recipe that friends can enjoy together and I put in some effort into transforming a simple wacky cake into something special, such as decorated cupcakes or adding some chocolate chips on the cake as it comes out of the oven or sprinkling powdered sugar when the cake completely cools. I use chocolate wacky cake as a base for an aquafaba meringue covered ice cream cake, Baked Alaska. My kids think it’s amazing that I put an ice cream cake in an oven under the broiler, lol.

Why is Rodelle Gourmet Baking Cocoa So Chocolatey?

There was one time I ran out of Rodelle Gourmet Baking Cocoa (affiliate link) and had to use a baking cocoa product that I used before I became a Rodelle brand ambassador. I was shocked to notice that the other baking cocoa looked pale in comparison and the chocolate flavor was negligible using the other brand.

I reached out to my contact at Rodelle to find out why and she told me that “Rodelle Gourmet Baking Cocoa has a lot richer flavor due to the higher percentage of cocoa fat that we add to the cocoa powder. Most cocoa powder on the market has 10-12% cocoa fat while ours has 16-18%. The Dutch-processing, or processing with alkali, also helps with the rich, dark color.” I think you’ll notice the difference and love the taste too.

I also used Rodelle Chocolate Extract to give the recipe an extra chocolatey flavor boost. If you prefer, you can substitute it with 2 teaspoons of Rodelle Vanilla Extract or 2 teaspoons of Rodelle Chocolate Extract instead. I usually buy Rodelle products when I find them at Costco and if they’re not available at yoru local store, you can check on Amazon.

Rodelle does not use any peanuts or tree nuts in their vanilla and extract products, however, as I noted above, their cocoa products now have an allergen advisory for almonds, coconut, and other allergens. If you have other allergen concerns be sure to reach out to their customer service department.

Nut-free alternative cocoa options: I haven’t tested this recipe with other brands but I would start with Gerbs Dutch Cocoa (affiliate). I also see that Guittard and King Arthur also make Dutch processed cocoa but I don’t know if they are nut-free at this time.

This recipe is free of peanuts, tree nuts, eggs, milk, soy, fish, shellfish, and sesame as written.

This recipe is a great cake base for my latest favorite recipe: Allergy Friendly Aquafaba Baked Alaska, which is also egg-free and nut-free!

Ingredients

  • 1 ½ cup all purpose flour
  • 1 cup organic sugar
  • 4 tablespoons Rodelle Gourmet Baking Cocoa
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 6 tablespoons oil I use extra virgin olive oil
  • 1 teaspoon Rodelle Vanilla Extract
  • 1 teaspoon Rodelle Chocolate Extract
  • 1 tablespoon apple cider vinegar
  • 1 cup water
  • Frosting options: allergy safe chocolate chips or powdered sugar

Instructions

  1. Preheat oven 350 °F
  2. If baking in a rectangular pan, mix the ingredients in a mixing bowl. If baking in a square pan (8×8 or 9×9), you can mix the ingredients in the pan if desired.
  3. Combine flour, sugar, cocoa, baking soda, and salt with a fork or a whisk until evenly mixed, make 3 wells.
  4. Pour the oil into one well, the extracts into one well, and pour the apple cider vinegar in last.
  5. Pour water over the entire container and stir until well mixed.
  6. Transfer the batter into a baking dish (if you didn’t mix it in a square pan) and bake in the middle rack of a preheated oven.
  7. The cake is ready when a toothpick poked into the center of the cake comes out clean: 18-20 minutes in a 9×13 pan or 30-40 minutes in a square pan.
  8. Cool for 30 minutes to serve as is OR sprinkle chocolate chips on the cake when it comes out of the oven OR cool completely and sprinkle with powdered sugar.

Recipe Notes

If you are baking in a square pan, you could mix the cake batter in the baking pan or in a bowl and then bake for about 30 minutes. If you are baking in a rectangular 9×13 pan, mix the batter in a bowl and then transfer the batter to a 9×13 baking pan and bake for 18-20 minutes.
