What is the flavor of the traditional cake used in many of Porto's birthday cakes?

The traditional cake flavor used in many of Porto's birthday cakes is vanilla. This classic flavor serves as a versatile base that complements a wide range of fillings and frostings, making it an enduring favorite for celebratory occasions. Vanilla cake is known for its simple yet rich flavor, which pairs well with a variety of toppings, such as fresh fruit, chocolate ganache, or buttercream frosting. This inherent sweetness and the ability to enhance other flavors is why vanilla is often chosen for birthday cakes, allowing for a delightful and satisfying experience.

In contrast, although chocolate, red velvet, and carrot cakes are popular cake flavors, they tend to be more niche in their appeal and are often chosen for specific occasions or personal preferences rather than as a traditional standard for birthday celebrations.
