Pączki are traditional Polish pastries, often enjoyed during Fat Thursday or Mardi Gras. They are deep-fried doughnuts typically filled with sweet fillings like jams, custards, or chocolate. The dough is rich, made with eggs, butter, and milk, giving pączki a soft and fluffy texture. These treats are often dusted with powdered sugar or glazed, making them visually appealing. While pączki are most popular in Poland, they have gained popularity in other countries, especially in areas with large Polish communities, such as the United States. They are a festive indulgence that celebrates the end of winter.
