Cream fat and sugar. Add eggs bit by bit. Mix flour and baking powder and stir in the egg liqueur. Grease a rabbit baking tin (approx. 1 litre capacity) and sprinkle with breadcrumbs.
Pour in the dough and bake in the preheated oven (electric: 175 °C/ gas: level 2) for about 1 1/2 hours. Let it rest for a short time, turn it over and let it cool down completely. Melt the chocolate coating separately. Cover the rabbits completely with the whole milk chocolate coating.
Allow to dry. Pour white couverture into a small freezer bag, cut off a tip and decorate the rabbit with it. Stick pistachios on it as a neck ruffle.
