Marble cake is one of the most delicious classic desserts, combining the flavors of chocolate and vanilla in an attractive marble-like design. This cake contains ingredients rich in nutritional benefits; eggs provide high-quality protein and essential vitamins like B12 to support energy, milk adds the calcium necessary for bone health, while cocoa powder contains antioxidants that promote heart health.
