What is "marble cake"?

Marble cake is a classic and beloved type of cake that is popular all over the world. It is made by combining two different flavors of cake batter, usually vanilla and chocolate, which are then swirled together to create a marbled effect. The cake batter is typically made from a mixture of flour, sugar, eggs, butter, and baking powder, and can include other ingredients, such as cocoa powder or vanilla extract, to add more depth and complexity to the flavor. The cake is often baked in a loaf or bundt pan and can be served plain or with a light glaze or frosting. Marble cake is a popular dessert for special occasions, such as birthdays or holidays, and can be found in bakeries, coffee shops, and supermarkets.
