In spite of what the name may imply, the Berlinerkranser is actually not German at all—in just about every recipe I have seen, these rich wreath-shaped butter cookies are said to hail from Norway, where they are a holiday tradition.
Could it be the result of German immigration patterns? Or perhaps these buttery wreaths call to mind the holiday decorations from Berlin?
Alas, while I cannot answer these questions, I can attest to their deliciousness. Buttery, crumbly, and complemented with a whisper of tartness from orange zest and plenty of sweetness from candied fruit garnish, these cookies are like a bite of holiday cheer.
