Preheat and prep: Preheat the oven to 350°F and line a few baking sheets with parchment paper.
Make the Dough: In a large mixing bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth and glossy. Add the egg, egg yolk, and vanilla extract, whisking until well combined.
1/2 cup unsalted butter, 3/4 cup light brown sugar, 1/2 cup granulated sugar, 1 large egg, 1 large egg yolk, 1 tsp. vanilla extract
Add Dry Ingredients: Using a rubber spatula, fold in the flour, cornstarch, baking soda, and salt until a soft dough forms. Be careful not to overmix.
1 ¾ cups all-purpose flour, 1 Tbsp. cornstarch, 3/4 tsp. baking soda, 1/2 tsp. fine salt
Mix-Ins: Stir in the white chocolate chips, chopped pistachios, and dried cranberries until evenly distributed throughout the dough. Feel free to add more of any mix-in if you want a little more throughout the cookie dough.
1/2 cup white chocolate chips, 1/2 cup chopped pistachios, 1/2 cup dried cranberries
Scoop and Bake: Scoop about 3 tablespoons of dough per cookie and place on the prepared sheet, spacing about 2 inches apart. Bake for 8-10 minutes, or until edges are set and centers still look slightly soft. Do not overbake. Start Timer
Cookie Scoot (Optional): Right out of the oven, use a round cookie cutter to gently swirl each cookie into a perfect circle for that bakery-style look.
Cool and Garnish: Let cookies cool on the baking sheet for 10 minutes before transferring to a wire rack. Start Timer Once cooled, spoon some of the pistachio butter over each cookie, sprinkle with crushed pistachios and chopped dried cranberries for a festive touch and a drizzle of white chocolate.
