Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
In a large mixing bowl, combine the flour, ghee (or softened butter), and powdered sugar.
Using your hands, gently work the ingredients together until a soft, smooth dough forms. The texture should feel almost like Play-Doh. Avoid overworking the dough.
Transfer the dough onto a clean countertop. You can roll it out to approximately 1 inch thick and cut it into traditional diamond shapes, or roll small portions into smooth balls.
Gently press a pine nut, almond, or pistachio into the center of each cookie.
Arrange the cookies on your prepared baking sheet, leaving a little space between each one.
Bake for approximately 18–20 minutes, checking earlier if your cookies are small. The bottoms should be just lightly golden, while the tops remain pale. Do not allow them to brown.
Remove from the oven and allow the cookies to cool completely on the baking sheet before touching or transferring them. They will be very delicate while warm.
Once cooled, serve and enjoy these buttery, melt-in-your-mouth Middle Eastern cookies!
