Marble Cake (or Marmer Cake in Bahasa Indonesia)

This recipe will show you how to make a marble cake that I used to make in Indonesia with my sis and bro. This is how I make and how I preferred it to be, so if you think you prefer it some other way, feel free to change whatever ingredients that suits your taste. Enjoy!!

Ingredients:
• 225 gr or 250 gr icing sugar (depending on the maker preference of sweetness)
• 250 gr soft flour
• A pinch salt
• 3 tablespoon Cocoa powder
• 6 egg yolks, 5 egg whites (if using baking powder)
9 egg yolks, 7 egg whites (if NOT using baking powder)
• 250 gr butter (preferably a mixture of 150 gr Wisman butter, 100gr normal butter to have a better taste)
• 1 tea spoon vanilla essence

How to make:

The White Marble

1. Please ensure that ALL your kitchen equipment is completely CLEAN and DRY, because no cake can be done if the equipment are not dry
2. Put butter and icing sugar with a pinch salt together in 1 container and mix it with a kitchen mixer (or if you don’t have any mixer you can mix them manually by whisker). Do this until all the mixture is nicely mixed with a yellowish color (because of the butter)
3. After everything is nicely mixed, put the egg yolks in one by one with the mixer running. Now this must be done slowly, if not, the yolk will not mixed properly with the butter & sugar mixture and you definitely don’t want that to happen now do you? Do this until the color starts to turn into a bit white
4. While waiting for the mixture to turn white, beat the egg whites using another mixer (or by whisker) until it becomes foamy and fluffy
5. Back to the butter sugar thingy, after it turns white, slow down the mixer by a bit and start to pour the flour SLOWLY (do not pour all the flour directly, because it will only make the dough not perfectly mixed and you have to throw this failure product). If you use baking powder, pour it now after the flour
6. By this time both egg whites and egg yolks should be finished. Now, pour the fluffy egg whites into the flour yolk butter sugar mixture, and start to fold them by PLASTIC SPATULA together. Again, this should be done slowly or else the mixture will not merge. You can only fold one way, so if you fold left than keep folding left and vice versa (or else the mixture will not rise when baked)
7. Give 1 teaspoon of vanilla essence to give a nice aroma to the cake
8. Start to preheat your oven at around 150 or 175 degrees Celsius

The Chocolate Marble

1. After folding, take 1/3 of the batter mixture and incorporate it with the cocoa powder.
2. Mix it slowly until all the white batter becomes brown (or black)

Finishing touch

1. Pour ½ of the white mixture first to a cake mold (preferably round shape 20x20cm). Cover all the inside part with a bit of cooking oil and soft flour all around it, just a thin layer should be enough. (This is done in order for the cake to be easy to taken out once the cake is done).
2. After that pour the all the chocolate mixture evenly throughout the mold. (Because you don’t want the cake to have only chocolate on left side and only vanilla on right side, you know what I mean?)
3. Pour the rest of the white mixture on top of the chocolate until finished
4. Use whatever thing you have (in my case 1 piece of chopstick) to mix the white and the chocolate mixture evenly so that the chocolate would not be only in the middle part of the cake
5. Bake the cake in the preheat oven for 30-45 minutes with 150 to 175 degree Celsius of temperature
6. Now until it’s done, turn the cake mold upside down and you will have a nice white and chocolate marble cake
