What purpose does vanilla serve in a cake?

Vanilla is commonly used in cakes to enhance their flavor. It adds a distinct, sweet, and delicate flavor that complements other ingredients in a cake. Vanilla pairs well with other flavors often found in cakes, including chocolate, butter, sugar, and eggs. It helps to balance the sweetness and can also enhance the richness and complexity of the cake.

Furthermore, vanilla has aromatic properties that contribute to the overall sensory experience of eating the cake. Its addition elevates the flavor profile of the cake and makes it more enjoyable. In baking, vanilla is usually used in the form of vanilla extract, vanilla beans, or vanilla paste, each adding a unique level of flavor and depth to the cake.
