Meringue - whisk egg whites till frothy with a hand held electric mixer, gradually add in the sugar in batches. Continue beating till egg whites are stiff but not dry.
Add ⅓ of the egg whites into the egg mixture, fold well with a rubber spatula. Then gently fold in the rest of egg whites till combined.
Pour the batter into 2 pieces - 20cm (8 inches) removable pie tray (no need to grease the tray), flatten batter with a spatula and bake in preheated oven 180 deg C for about 13-15 minutes. After baking, immediately drop pie tray on table top 2 to 3 times to release the hot air and prevent shrinkage. Leave cakes to cool down completely before removing them from trays.
Chocolate cream - Please chocolate pieces over a pot of hot water (do not on the heat) and set aside. Lightly boil 85ml whipping cream at medium heat and mix into the chocolate pieces, stir well with a hand whisk followed by vanilla extract and kahlua liqueur to smooth and leave mixture to cool.
Whisk 200ml fresh topping (non dairy) cream to peak form (not too stiff) and fold into chocolate mixture with a rubber spatula.

Topping - Pour 150ml fresh topping (non dairy) cream together with coffee paste and kahlua liqueur into mixing bowl and stir well. Then whisk cream to stiff peak form.
Remove cake from the adjustable cake ring. Then scoop whipped cream into piping bag and pipe pattern on top with nozzle tip (#1M). Lastly dust with some Valrhona cocoa powder on top. (or decorate as desired)
Return cake to the refrigerator and chill until it is ready to serve. (cake can be refrigerated up to 5 days)
Notes
Remaining piece of sponge cake can be kept in the freezer (wrap with baking paper and in a zip lock bag) or place it directly on top of the chocolate cream (step 7)
