The Royal Dansk butter cookies are luxury cookies baked in Denmark that have a reputation for being crisp, buttery, and full of flavor. One thing that stands out is their blue tin. The tin is used to maintain freshness and has become a staple for the Royal Dansk butter cookies. Plus, people reuse the tins for other purposes as well. The tin features an iconic mix of five cookie shapes. Finnish style, country style, vanilla ring, pretzel style, and coconut. The company uses non-GMO ingredients, no preservatives, and no artificial flavors to make them taste so good!
