Chocolate Orange Marble Chiffon Cake

Directions

1. Cream the egg yolks and sugar (Group A) by using high-speed mixer.
2. In separate container, lightly combine the canola/vegetable oil, fresh orange juice, orange rinds and vanilla essence by using spoon or fork. Pour this mixture into the egg yolk and sugar mixture by using spatula.
3. Fold the flour and milk powder into the cake batter by using spatula. Mix well and set aside.
4. In separate bowl, mix egg whites and sugar with high speed mixer. Add the cream of tar-tar slowly into the mix. Keep on mixing until we get stiff egg whites with soft peak - this means the mixture doesn't fall back under its own weight.
5. Combine the egg white mixture to the orange cake batter by using spatula.
6. Take some of the cake batter and mix it with the cocoa powder.
7. Add few drops of orange colouring if necessary to the other cake batter.
8. Alternately pour the orange and chocolate cake batters into a tube pan. Do not grease the tin.
9. Bake the cake for about 50-55 minutes in a preheated oven. Keep a small fire throughout the baking process and do not attempt to open the oven lid before the cake is baked for at least 45 minutes.
10. Once done, let the cake cool down completely before releasing the cake from the tin. Use a sharp thin blade to take the cake out from the tin.
