Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

In a large mixing bowl, cream together the softened butter, granulated sugar, light brown sugar, and honey until light and fluffy.

Add the egg and vanilla extract, mixing until fully incorporated.

In a separate bowl, whisk together the flour, baking soda, and salt before gradually adding it to the wet ingredients until just combined.

Fold in the roughly chopped pistachios into the dough.

Scoop rounded tablespoons of the dough onto the prepared baking sheet, spacing them about 2 inches apart.

Sprinkle the tops of the dough balls with flaky sea salt before baking.

Bake for 10 to 12 minutes until the edges are golden and the centers are soft.

Let the cookies cool on the sheet for 5 minutes before transferring to a wire rack.
