    This coffee frosting is completely delicious! You’ll love Chocolate Cream Cheese Frosting on this cake too.

    What is Wacky Cake?

    Known as Wacky cake, ‘Crazy Cake‘ or Depression Cake, this type of cake was developed after World War II when certain supplies were hard to find. 

    The cake does not need eggs, butter or dairy products to make a moist, flavorful cake.

    It rises thanks to a chemical reaction between the baking soda and vinegar.

    You’ll never taste the vinegar.

    It’s a fun cake to make and perfect regular cake ingredients aren’t available. Also great for anyone dairy-free.

      I made this for book club and everyone flipped out! Instead of frosting, I made an easy ganache with heavy cream and high quality chocolate chips and poured that over the cake. Wowzers!

      I plan to make this into a small birthday cake for my daughter because we will be celebrating the day before leaving for the holidays and donโ€™t want any leftovers. Do you think I could bake this in a 6 inch pan for a slightly taller cake? If, so what bake time would you recommend? Iโ€™ve never made this before, but it sounds delicious and a great idea for my coffee-loving, dairy sensitive girl!

        Hi Lindsay. Iโ€™ve only made this and other wacky cakes in this format. Iโ€™ve never heard of making them taller and donโ€™t know that the chemical reaction of this type of cake would support trying to make it rise taller or work in a different size pan. Iโ€™d recommend making the recipe as written.

      I have made the chocolate wacky cake for many years โ€ฆ never used hot water recipes always called for cold water ? Iโ€™m a bit uneasy about trying the hot coffee rather than room temp liquid . I have a Vegan in the family and the cake is a great go to dessert for her . Would love to try the coffee addition but donโ€™t want a flop ๐Ÿ˜ฉ
      Reassurances please .
      Thank you

        Hi Sherry. Using hot coffee gives more flavor though room temperature or even cold coffee also work they just donโ€™t produce the same level of flavor. My feeling is you should do what you are most comfortable doing. Itโ€™s not worth the worry if youโ€™d rather stick with what you know and are comfortable doing! Do give it a try sometime; the flavor it adds is really fantastic.

      Do you think you can make cupcakes with this recipe.

        You should be able to. Fill the cupcake liners 1/2 to 2/3 full and bake until done (test with a toothpick inserted in the middle) about 15 to 20 minutes

        My apologies Sharon. It is whisked in with the dry ingredients. I’m sure it will still be delicious as you’ve made it.
