Letterbanket is a flaky Dutch pastry that is typically made with a combination of flour, butter, and eggs. The pastry is shaped into letters, filled with almond paste, and dusted with sugar. The letter is usually the first letter of the family’s last name, but sometimes each person gets a small letterbanket with the first letter of their name.

These sweet treats are traditionally served on December 5, known as Sinterklaasavond. Letterbankets are also quite popular in the United States, particularly in Iowa and Michigan.
