Zebra Cake

Ingredients
4 large eggs, at room temperature
1 cup granulated sugar
1 cup milk, at room temperature
1 cup oil
2 cups all-purpose flour
1 tsp vanilla essence
1 tablespoon baking powder
2 tablespoons dark cocoa powder

Method:

In a large mixing bowl, combine eggs and sugar. 

Using a hand-held electric mixer or wire whisk beat until the mixture is creamy and light in colour.

Add milk and oil, and continue beating until well blended.

In a separate bowl, combine and mix flour, vanilla powder and baking powder. Gradually add the flour mixture to the wet ingredients and beat just until the batter is smooth and the dry ingredients are thoroughly incorporated.
Divide the mixture into 2 equal portions. 

Keep one portion plain. 

Add cocoa powder into another and mix well.

Preheat the oven to 350F (180C).

Lightly grease a 9" round pan.

The most important part is assembling the cake batter in a baking pan.

Put 3 heaped tablespoons of plain mixture into the middle of the baking pan. 

Then 3 tablespoons of cocoa batter and pour it in the centre on top of the plain batter.

IMPORTANT! Do not stop and wait until the previous batter spreads - KEEP GOING! 

Do not spread the batter or tilt the pan to distribute the mixture. 

It will spread by itself and fill the pan gradually. 

Continue alternating the batters until you finish them.

Bake in the oven for about 40 minutes.
