[[Sponge cake]]s (or foam cakes) are made from whipped eggs, sugar, and flour. Traditional sponge cakes are leavened only with eggs. They rely primarily on trapped air in a protein matrix (generally beaten eggs) to provide [[leavening]], sometimes with a bit of [[baking powder]] or other chemical leaven added. Egg-leavened sponge cakes are thought to be the oldest cakes made without yeast.

[[Angel food cake]] is a [[white cake]] that uses only the whites of the eggs and is traditionally baked in a tube pan. The French [[Génoise cake|Génoise]] is a sponge cake that includes [[clarified butter]]. Highly decorated sponge cakes with lavish toppings are sometimes called ''gateau'', the French word for cake. [[Chiffon cake]]s are sponge cakes with vegetable oil, which adds moistness.<ref>{{cite book |last1=Medrich |first1=Alice |title=Joy of Cooking |date=1997 |publisher=Scribner |location=New York |isbn=0-684-81870-1 |page=949}}</ref>
