From The Old Town’s website in my translation. Sadly they don’t have the original text up, though it could be fun.
Vanilla Wreaths - 1866
Old recipe for Vanilla Wreaths from 1866.
Knead flour, egg, butter, sugar, vanilla and almonds together, until the dough doesn't stick to your hands.
Roll the dough into finger thick sauceges
Cut each into about 12 cm long pieces and shape the wreaths so they have a large hole in the middle. Otherwise they will close. Use a bit of flour on your fingers while shaping them.
If you have a meat grinder with a vanilla wreath plate use that.
Bake them golden brown for 20 min at 180 C
