Mix the ingredients for the dough together and place on the baking tray (lined with baking paper). Mix coconut, sugar and van sugar and spread on the dough. Bake at 210 ° C top / bottom heat on a low rack for 15 - 20 minutes until the cake is golden brown.
In the meantime, heat the whipped cream with the butter.
As soon as the cake comes out of the oven, spread the hot (important!) Cream mixture on the cake with a spoon.
