For the nougat caps, first prepare the dough.
Knead a smooth dough from flour, baking powder, sugar, vanilla sugar, salt, milk, butter and rum aroma. Refrigerate for approx. 30 minutes.
Roll out the dough to a thickness of approx. 3 mm. Cut out cookies with a small round cookie cutter. Bake at 175° for 10 minutes.
Mix Nutella and almond slivers. Crumble 1/3 of the cookies and mix into the cream. Place small heaps on the cookies in the shape of a dome and refrigerate for approx. 2 hours.
Cover the cookies with chocolate icing.
