Swirled Zebra Cake - cooking recipe

Ingredients

4 eggs
1 cup plain low-fat yogurt
2 cups sugar
2 cups all-purpose flour
2 teaspoons baking powder
2 tablespoons cocoa powder

Preparation

Preheat the oven to 350 degrees F, and lightly grease an eight or nine inch cake pan.
You need two separate mixing bowls. In each bowl, mix two eggs, 1/2 cup of yogurt and 1 cup sugar.
To each bowl, add 1 cup flour and 1 teaspoon baking powder.
To one of the bowls, mix in the cocoa powder.
Mix the batter thoroughly in each bowl.
Put one heaping tablespoon of the white batter in the middle of the cake pan. Next add one heaping tablespoon of the chocolate batter on top of the white batter. Continue alternating the batters until they're gone.
Don't worry if the batter seems to go to one side of the pan; the batter will even out and look great.
Bake for 30 to 35 minutes or until done in the center.
