Marble Buttercake

Ingredients:
227gm unsalted butter
200gm castor sugar
227gm self raising flour
1/2 tsp salt
3/4 tsp baking powder
4 eggs
2 tbsp cocoa powder
7 tbsp milk
1 tsp vanilla essence

Method:

1. Preheat oven to 170 degree Celsius (my oven would be 155 degree)
2. Grease and lightly flour an 8 x 8 square baking pan or a tubed pan
3. Mix cocoa powder and half of the milk in a medium bowl and set aside.
4. In a mixing bowl, beat butter and sugar until creamy. Add eggs one at a time, beating well after each addition. Add salt.
5. In a separate bowl, sift flour and baking powder 2-3 times. Fold in the sifted flour into the butter mixture alternately with milk, starting and ending with flour.
6. Add vanilla essence and combine well.
7. Transfer 1/3 of the batter into the chocolate mixture and mix well.
8. Scoop the plain batter and chocolate batter alternately into the baking tin. Run a fork or a knife through it to get marbled effect. No specific way, just run it as you like...but, actually there is a kinda cool way using a spoon so that you can get a kind of wave effect but that would be in another entry...(soon :)). Smooth the top and bake for about 45 - 50 minutes or until a skewer inserted into the center of the cake comes out clean.
9. Remove cake from oven and let it cool completely.
