Place 1 ball of confectionery on each, fill up with dough until the confectionery is covered. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 20-25 minutes. Rest the muffins in the tin for 10 minutes.
Remove and let it cool down. For the icing, mix icing sugar, egg white, grated coconut and 2-3 tablespoons of water. Brush the muffins with the icing. Roast the coconut chips in a pan without fat. Decorate muffins with it.
