What is the signature item that combines a rich chocolate cake with cream cheese frosting at Porto's?

The signature item that combines a rich chocolate cake with cream cheese frosting at Porto's is indeed the Red Velvet Cake. This cake is known for its distinctive red color, which is typically achieved using food coloring, and it features a moist and velvety texture. The cream cheese frosting adds a deliciously tangy contrast to the sweetness of the cake itself, enhancing the overall flavor experience.

While other options like chocolate lava cake, chocolate ganache cake, and mocha cake are also popular desserts, they do not specifically incorporate both the rich chocolate cake and cream cheese frosting combination that the Red Velvet Cake does. The emphasis on the cream cheese frosting is a hallmark of Red Velvet Cake, distinguishing it from other chocolate-centric desserts on the menu.
