# What You'll Need:
→ Dry Ingredients
01 - 2 cups all-purpose flour (250 g)
02 - 1/2 teaspoon fine sea salt
→ Wet Ingredients
03 - 1 cup unsalted butter, room temperature (226 g)
04 - 3/4 cup powdered sugar (90 g)
05 - 1 teaspoon pure vanilla extract
→ Add-ins
06 - 3/4 cup roasted, shelled pistachios, roughly chopped (90 g)
07 - 4 oz dark chocolate (60–70%), chopped into chunks (115 g)
→ Finishing
08 - 1 large egg, lightly beaten (egg wash)
09 - 1/4 cup coarse sugar (e.g., turbinado or demerara) (50 g)

# Step-by-Step Guide:
01 - Whisk together the flour and fine sea salt in a medium bowl. Set aside.
02 - Beat the unsalted butter with powdered sugar until smooth and creamy, approximately 2 minutes. Incorporate the vanilla extract.
03 - Add the flour mixture gradually while mixing on low speed until just combined.
04 - Gently fold in the chopped pistachios and chocolate chunks until evenly distributed throughout the dough.
05 - Divide the dough into two equal portions. Shape each into a log measuring approximately 1.75 inches (4.5 cm) in diameter on parchment paper.
06 - Wrap each log tightly in parchment paper and refrigerate for at least two hours or until firm.
07 - Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper.
08 - Unwrap the chilled dough logs. Brush the surface with beaten egg, then roll in coarse sugar to evenly coat.
09 - Using a sharp knife, cut the logs into 1/2-inch (1.25 cm) thick slices. Arrange cookies at least 1 inch apart on the baking sheets.
10 - Sprinkle each cookie with flaky sea salt to enhance flavor.
11 - Bake for 12 to 14 minutes, until the edges just begin to turn golden brown.
12 - Let cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
