This classic Neapolitan cake is a delicious combination of vanilla, chocolate, and strawberry flavors. To make this cake, you will need to bake three separate layers of cake, one vanilla, one chocolate, and one strawberry. Once the cakes have cooled, you can stack them on top of each other with a layer of frosting in between each layer. Finally, frost the entire cake with a vanilla buttercream frosting and decorate as desired.
