Shirini Keshmeshi are crinkled raisin cookies and taste buttery, are chewy on the inside and crispy on the outside and absolutely my favorite for persian Norouz. For me Shirini Keshmeshi must have crinckles on top and golden edges. Therefore I made them with butter, flour, powdered sugar (creates their cracked appearance), a little bit oil, an egg, vanilla extract and they are loaded with raisins for a fine texture, sweetness and an irresistible chewing experience.
