This coconut marble cake is a tropical twist on the classic marble cake. To make this cake, you will need all-purpose flour, baking powder, salt, unsalted butter, granulated sugar, eggs, vanilla extract, milk, shredded coconut, and cocoa powder. The cake batter is divided into two parts, and one part is mixed with shredded coconut to create the coconut batter. The two batters are then swirled together with cocoa powder to create the marble effect. This cake is moist, tender, and has a beautiful coconut and chocolate swirl pattern. It's perfect for anyone who loves coconut desserts.
