Preheat your oven to 350°F (175°C) to ensure even baking.
In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy, about 2-3 minutes.
Add the pure vanilla extract and ground pecans to the mixture, mixing until well combined.
In a separate bowl, whisk together the all-purpose flour and crushed potato chips, then gradually add to the wet ingredients until just combined.
Using a cookie scoop, portion out the dough onto a lined baking sheet, leaving space between each cookie.
Bake for 12-15 minutes until the edges are golden brown; the centers may look soft but will firm as they cool.
Let cookies cool for a few minutes on the baking sheet before transferring to a cooling rack. Drizzle with melted chocolate and sprinkle with flaky sea salt while warm.
