Wacky cake is a spongy, cocoa-based cake. It is unique in that unlike most pastries and desserts, no eggs or milk are used to make the cake batter.
It is commonly believed Wacky Cake may have been created as the result of rationing during World War II, when milk and eggs were scarce. Active ingredients in wacky cake include flour, sugar, cocoa powder, baking soda, vegetable oil, white vinegar and vanilla extract.[1] Some recipes add brewed coffee as an additional ingredient. The cake may be topped with icing or confectioner's sugar, or even served plain.
It is not known for a fact where Wacky Cake first originated, or who created it. However, it has been said that the recipe was first created by Beatrice Fe O'Hearn, who has passed it down through her family and friends since the late 1930s. The cake is considered a popular delicacy at bake sales in numerous rural regions of the United States.
