Bring orange juice and sugar to the boil. Stir pudding powder in 2 tablespoons of cold water until smooth, add and bring to the boil once. Add 40 g pistachios and let the cream cool down. Whip cream and vanilla sugar until stiff and fold into the cooled cream.
Cut out a rabbit shape and 2 ears from the sponge cake base. Fill everything with the cream and put it together. Stir icing sugar and lemon juice until smooth. Put some aside and colour the rest of the icing pink with red food colouring.
Cover the rabbit with it. Pour white glaze into a piping bag with a small perforated spout and decorate the rabbit with it. Colour the rest of the glaze blue and spray eyes and dots onto the fly.
Spread the ears with the remaining pistachios. Results in about 12 pieces.
