For the Berlinerschnitten, beat egg whites with a pinch of salt and 3 tablespoons sugar until firm. Meanwhile, boil the remaining sugar with the water for 2 1/2 minutes.
Mix the dissolved sugar into the beaten egg whites until the mixture has cooled down and the mixture has the desired firmness.
In the meantime, melt the chocolate with the coconut oil. Cut the ice cream waffles in half and pipe the beaten egg whites onto the waffle using a piping bag with a star-shaped nozzle.
Quickly dip the beaten egg whites including the wafer into the chocolate and let them drip off on a grid. Allow the chocolate to dry a little, sprinkle with coconut and place in the refrigerator to set.
