For the cheese rings, cream butter and yolks until fluffy. Stir in Parmesan cheese, salt and paprika powder. Mix flour with baking powder and fold in.
Use a piping bag to pipe the mixture onto a baking tray lined with baking paper. Bake at 180 degrees for 15 minutes and remove the cheese rings from the tray when cool.
Preparation Tip:
The cheese rings are the ideal snack to accompany wine or beer.
