Chop the nuts finely. Mix flour, pudding powder and baking powder. Mix palm fat and sugar with the whisk of the hand mixer. Carefully stir in the eggs one after the other. Add the flour mixture, nuts and flavours.
Dye green with green food colouring. Form approx. 32 walnut-sized balls from the dough. Spread half of the balls on 2 baking sheets lined with packing paper. Bake one after the other in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for about 15 minutes.
Remove from the oven and let it cool down. Melt butter and mix with icing sugar and milk to a glaze. Decorate about half of the biscuits with icing and let them dry for about 30 minutes.
