Whisk butter, coconut oil and 100 g icing sugar with the whisk of the hand mixer until white and creamy. Add flour, 50 g grated coconut, salt and vanilla flavouring and knead to a smooth dough. Form into a dumpling, wrap in foil and chill for about 1 hour. Halve the dough and roll out between two layers of baking paper 4-5 mm thick. Cut out palm trees from the dough with a cookie cutter and place them on 4 baking trays lined with baking paper. Bake the trays one after the other in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for about 10 minutes.
Let them cool down on cake racks. Stir 150 g icing sugar and coconut milk until smooth. Coat half of the palm trees with icing. Decorate all palm trees with a cast rim and 30 g grated coconut. Let the icing dry
