Using an electric hand mixer, beat 1 cup of room temperature butter with 3/4 cup of brown sugar and 1 cup of granulated sugar in a large bowl until creamy
Add 2 large eggs and 2 teaspoons of vanilla extract and mix until fully incorporated
Add 375 grams (3 cups) of all purpose flour, 1 teaspoon of baking soda and 1/2 teaspoon of salt into the bowl and mix until just combined
Fold 1 cup of dark chocolate chips and 1 cup of chopped pistachios into the dough until evenly distributed
Using a greased cookie dough scoop, drop 2 tablespoons of dough onto a baking sheet and freeze for about 30 minutes
When you are ready to bake, preheat your oven to 350 degrees
Place the chilled portions of cookie dough onto a parchment lined baking sheet at least 2 inches apart
Bake the cookies in a 350 degree oven for 10-12 minutes or until the edges are lightly golden brown
Transfer the baking sheet onto a cooling rack and allow the cookies to rest on the baking sheet for at least 5 minutes before transferring directly onto the cooling rack
Store leftovers in an airtight container at room temperature for 3-4 days or freeze for up to 3 months
