Instructions

• Using a small food processor, or a knife on a cutting board, finely chop the pistachios. For extra texture, leave a few pieces of the pistachios slightly larger.
• In a large bowl, combine ground pistachios, flour, ¼ cup of powdered sugar, and salt. Mix to combine.
• Add butter and vanilla to the dry ingredients. Mix and mash together until you get a soft dough.
• Cover and chill the dough for 30 minutes to help prevent overspreading when baking.
• Preheat your oven to 350°F. Line a large baking sheet with parchment paper.
• Uncover your chilled dough and pinch off 1 tablespoon sized portions. Roll into smooth balls and arrange on the baking sheet.
• Bake in the center of your preheated oven for 12 to 15 minutes or until lightly browned along the edges.
• Cool the cookies for 5 minutes on the baking sheet or until cool enough to handle.
• Fill a medium bowl with about ¾ cup of powdered sugar then toss the cookies in the sugar to coat the outside.
• Arrange the cookies on a wire rack and set aside to cool completely to room temperature before serving.
