Beat the egg whites until stiff. Gradually add the vanilla sugar and sugar. Chop the prunes and stir into the egg whites together with the remaining ingredients. Use a teaspoon to put small piles of dough from the mixture on a baking sheet lined with baking paper (you can put the dough piles close to each other, the dough hardly runs apart when baking).
Bake the macaroons in a preheated oven at 175 ° C for about 15 minutes.
Tip: You can also replace some of the prunes with raisins or other dried fruits.
