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.
Espresso Cake
Wacky cake is usually made as a chocolate cake.
The addition of some hot coffee transforms this recipe to rich, mocha flavored cake.

This looks so amazing. We’re pre-baking our cakes for our final for pastry school tonight, and I wanted a layer of my 3 tier cake to be this flavor – will this hold in the fridge until we start decorating next week?
