Preheat oven to 350F and line a baking sheet with parchment paper. Set aside. In a medium bowl, whisk all-purpose flour, sea salt, baking soda and baking powder. Add sugars and butter to a stand mixer and cream together for about 2 minutes, scraping down the sides. Add egg and pure vanilla extract and mix again until just combined.

Transfer dry ingredients into the stand mixer bowl and run again until combined. Fold in chopped candy with a spatula, then scoop 3-tablespoons dough balls and drop them on the prepared pan. Bake for about 14 minutes or until lightly golden. Allow cookies to cool on the baking sheet for about 10 minutes, then transfer to a wire rack.
