Split
the eggs. Beat the egg whites until they are fluffy. Beat the yolks with half
of the sugar until they are white and thick. Beat the butter with the rest of
the sugar, mix with the yolks. Stir in flour and custard powder. Carefully
stir in the egg whites. Split the batter in two; in one half, stir in the
spices and the cacao.
Put a very thin layer of dark batter in an oven dish and put under the grill
for approximately 3 minutes (watch out for burning!). Add a layer of yellow
batter and repeat the procedure; than dark again, etc, until all batter
finished. Turn off the grill and leave the cake in the oven for 15 minutes.
Spiced layer cake (Kwee Lapis) is an Indonesian recipe, which
is also very popular in the Netherlands (where it is called "spekkoek")
It takes some tame to prepare but the result is magnificient and delicious.
