Marble Butter Cake

This mouth watering Marble Butter Cake is in my baking list for Christmas, but due to being overly busy and tired I have to skip it.  Even though all the ingredients are already there in my kitchen storage, but it takes quite a while for me to kick-start my baking mode.  Today I've made it, here is this soft, light and deliciously yummy Marble Butter Cake to share with all....

Ingredients:
250 g salted butter (Golden Churn)
200 g self raising flour
150 g caster sugar
4 egg yolks
60 ml. milk
10 g cocoa powder
4 egg white
50 g caster sugar

Methods:

1. Cream butter and sugar until light and fluffy.
2. Add the egg yolk, one at a time and beat each one into the batter before adding the next.
3. Fold in half of the flour, mix using the lowest speed, then add all the milk, finally the rest of the flour.  Mix just until all the flour has been incorporated into the batter.
4. Transfer 1/3 of the batter into a bowl, add cocoa powder and stir to mix using a spatula.  The remaining 2/3 batter put aside.
5. In a clean mixing bowl whisk the egg whites until foamy.
6. Add the sugar gradually and whisk until stiff peaks form.
7. Add in 1/3 of the egg white to the batter with the cocoa and fold in using a spatula.
8. Add the remaining egg white to the batter without the cocoa powder and fold this in.
9. Pour the batter without the cocoa in a lightly greased 8" round pan.  Place spoonfuls of cocoa batter around the sides and middle of the cake.
10. Use a spatula to make circular motions to create swirls.
11. Bake in a preheated oven of 170 degree Celsius for roughly one hour (for my oven) or until when a skewer inserted comes out clean.
12. Cool the cake in the pan for about 20 minutes before transferring into a baking rack to cool completely.
13. Slice and let's enjoy our afternoon tea!
