Preheat the oven to 350°F (175°C).

Line two baking sheets with parchment paper.

In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy (about 2-3 minutes).

Beat in the eggs one at a time, followed by the vanilla extract.

In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt.

Gradually add the dry mixture to the wet mixture, stirring gently to combine.

Fold in the chopped pistachios until evenly distributed.

Use a cookie scoop or tablespoon to drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart.

Sprinkle with a pinch of sea salt if desired.

Bake for 10-12 minutes, until the edges are lightly golden and centers are set.

Allow to cool on the baking sheets for 5 minutes before transferring to a wire rack.
