National Pfeffernuesse Day is observed worldwide every December 23 and is dedicated to the enjoyment of pfeffernuesse, or peppernuts, which are tiny spiced cookies. These cookies are a traditional Christmas treat in Denmark, Germany, Belgium, and the Netherlands and have been part of yuletide celebrations in Europe since the mid-19th century. They were introduced to the United States by European immigrants and have gained popularity there as well. Typically made with flour, brown sugar, and spices such as cloves, cinnamon, and anise, pfeffernuesse can also be sweetened with honey or molasses and are sometimes dusted with powdered sugar. While they are hard when first baked, they soften over time, leading many to prepare them a few days before Christmas to enjoy them fresh on Christmas Eve. This practice likely contributes to the celebration of National Pfeffernuesse Day on December 23.
