Hamantaschen are traditional Purim cookies that are shaped like triangles and filled with various sweet fillings such as fruit preserves, chocolate, or poppy seed paste. These delicious treats are a must-have during Purim celebrations. The dough is made with butter, sugar, eggs, and flour, and is then rolled out and cut into circles. The filling is placed in the center of each circle, and the dough is folded up to create the iconic triangular shape. Hamantaschen are typically baked until golden brown and enjoyed by people of all ages.
