Preheat your oven to 350°F (175°C) and line your baking sheets with parchment paper.
In a medium bowl, whisk together the all-purpose flour, baking soda, and fine sea salt. Set this mixture aside.
In a large mixing bowl, combine the unsalted butter and coconut oil. Beat until light and fluffy.
Add the granulated sugar, dark brown sugar, and lime zest to the creamed mixture. Mix until well combined.
Beat in the eggs one at a time, followed by the vanilla extract. Scrape down the sides of the bowl.
Gradually add the dry ingredients into the wet mixture, mixing at a low speed until just combined.
Gently fold in the white chocolate chips until evenly distributed throughout the dough.
Using a cookie scoop or spoon, drop dough onto prepared baking sheets, spacing them about 2 inches apart. Bake for 10-12 minutes or until edges are lightly golden.
Allow cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. Enjoy!
