01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together the flour, baking soda, baking powder, and fine sea salt until evenly blended.
03 - In a large bowl, beat the butter, honey, granulated sugar, and brown sugar until light and creamy, approximately 2-3 minutes.
04 - Add the egg and vanilla extract to the butter mixture, mixing until thoroughly incorporated.
05 - Gradually add the dry ingredients to the wet ingredients, mixing just until no dry streaks remain. Avoid overmixing to maintain tenderness.
06 - Fold in the chopped pistachios, reserving 2 tablespoons for topping.
07 - Scoop tablespoonfuls of dough onto the prepared baking sheets, spacing at least 2 inches apart to allow for spreading.
08 - Press a few reserved pistachios onto each dough ball and lightly flatten the tops slightly.
09 - Bake for 11-13 minutes, or until the edges are golden brown and the centers appear just set.
10 - Remove from oven and sprinkle immediately with flaky sea salt. Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
