For the pumpkin seed cookies, knead flour, powdered sugar, butter, rum and pumpkin seeds into a dough. Roll out this dough on a floured work surface to a thickness of approx. 2 mm, cut out Christmas trees and bake at 180 °C for approx. 10 – 15 minutes.
Then glue two Christmas trees together with Nutella and decorate with the melted dark chocolate.
