Mandelbrot is a traditional Jewish cookie that is often enjoyed during Purim. It is similar to biscotti, as it is a twice-baked cookie that is crispy and crunchy. The dough is made with flour, sugar, eggs, and oil, and it is flavored with vanilla and almond extract. Chopped nuts, such as almonds or walnuts, are added to the dough for extra flavor and texture. The dough is shaped into logs and baked until golden brown. Once cooled, the logs are sliced into cookies and baked again until crispy. Mandelbrot is a delicious treat that pairs well with a cup of coffee or tea.
