Easy Brazilian Zebra Marble Cake

Beat egg whites until stiff. Add half the sugar and beat until firm. Set aside

Beat egg yolks with the remaining sugar until light and creamy. Add water and beat until foamy

Add baking powder, flour, and oil, beating until smooth

Gently fold the egg white mixture into the batter until incorporated

Divide the batter into two bowls. Stir cocoa powder into one bowl

In a greased and floured pan, place one spoonful of white batter in the center. Top with one spoonful of chocolate batter

Repeat, placing spoonfuls of white and chocolate batter alternately in the center, until all batter is used. This creates the zebra pattern
