Ingredients
Makes 1 (PME round cake pan 6-inch)

(A)
• 35g salted butter, melted
• 35g whole or semi skimmed milk
• 10g golden granulated sugar

Egg Yolks:
• 2 large egg yolks, cold
• 1/2 tsp vanilla extract
• a pinch of sea salt
• 1 tbsp, 10g cocoa powder
• 2 tsp instant coffee
• 35g cake flour or 23g plain flour + 12g corn flour

(B)
Egg Whites:
• 2 large egg whites, cold
• 1/2 tsp distilled malt vinegar
• 35g golden granulated sugar, optional

(C)
Dark Chocolate Ganache:
• 55g, 5 tbsp dark chocolate chips
• 25g, 2 tbsp hot milk

(D) White Chocolate Ganache:
• 30g, 2 tbsp white chocolate chips
• 10g-12g, 1 tbsp hot milk

Above (C) dark and (D) white chocolate ganache, use a very hot milk to whisk with the chocolate chips until smooth and glossy. 

Method:
1) In a saucepan, add salted butter, milk, sugar, and bring to a simmer until the sugar dissolves.
Turn off the heat. whisk the egg yolks to break them up one by one. Add the sieved cake flour, use a whisker, continue to whisk until smooth and well combined.

2) In a separate bowl, start beating the whites at low speed until they are foamy, then add half tsp of white vinegar and add sugar a little bit at a time, move on to medium or even medium-high speed, do not beat on high, until nearly stiff peaks, about 5 minutes. Turn the whisker upside down and those peaks can hold proudly.

3) Fold about 1/4 of the egg whites into the yolk mixture, then repeat until the batter is evenly combined. Pour the batter into 6-inch pan, banging and tapping your pan a few times before popping a cake into the oven, to prevent release any large air bubbles, because you don't want too much air in the cake batter, it will create holes and cracks in the finished product.

4) Use a large baking pan for a hot water bath, steam bake in preheated oven to 100ºC, always use (oven thermometer) and bake with both top and bottom heat without fan assisted and bake for 65 minutes, and increase to 130-150ºC for another 10 minutes.

5) After it is baked, let it stand in the oven for 15 minutes, until the oven temperature reached 50ºC, which can avoid your cake to collapse. Dropping the cake pan from high to prevent the cake to shrink too much during cooling. Place treats on tray! It is best served chilled.

6) Once the cake is cool, remove the lining, then pour the warm chocolate ganache on to the centre of the cake and letting it run down the sides and pour the white chocolate ganache in the piping bag for drawing on the cake top and use a toothpick for a swirls. Transfer the cake to a plate for serving. Any leftover cake can be covered and kept in the fridge for 2 days.

Reminder: To make sure your cake to succeed even better. It is best to use an oven thermometer and you'll always have the exact temperature of your oven in mind.

Helpful Tips:
1) Do not over or under-beat the egg whites. 
2) Use a clean, dry bowl, free of yolk and any other oil or grease while beating egg whites.
3) Beating egg whites is a very important process, It will help your cakes rise with perfectly.
4) Folding egg whites into a cake batter. Do not stir and never use an electric mixer.
5) I recommend one thing, do not pour the yolks mixture into the whipped whites because doing so you compress the albumen and all the work is gone. 
6) For guaranteed results it's important to follow exactly this recipe and baking at the right temperature also recommended to use an oven thermometer.
7) Please understand that everyone's oven work differently. You should also check the temperature of your oven. if not, your cake won't rise well.
8) Do not bake the cake quickly at a high temperature and don't remove hot cake out of a baking pan. otherwise the cake could fall apart and crack on top. Baking cake at a lower temperature will help the cake rise much higher and bake more evenly.
9) You can test the cake by poking it with a skewer, if it's cooked the skewer will come out clean. if not pop it back in the oven and bake until it's ready.
10) Cover with foil after a few minutes if the cake of top starts to get brown and continue rising nicely with a golden top.
11) Store in covered containers in the fridge and consumed within 2 days.
