In a medium bowl, whisk together the flour, baking soda and salt.
In the bowl of a stand mixer fitted with the paddle attachment, cream together the butter, white sugar and brown sugar until light and fluffy, about 2 minutes.
Add the vanilla extract then add the eggs one at a time, beating between each addition.
Add the flour mixture to the stand mixer and beat just until combined.
Stir in 1 cup of the white chocolate chips and the crushed candy canes. Cover the bowl with plastic wrap and refrigerate it for a minimum of 30 minutes and up to overnight. (See Kelly’s Notes.)
Preheat the oven to 350°F. Line two baking sheets with parchment paper.
Drop 2-tablespoon mounds of dough on the prepared baking sheets, spacing the mounds at least 2 inches apart. Stud the cookies with the remaining white chocolate chips then sprinkle on additional crushed candy canes.
Bake the cookies until the edges are pale golden and the centers are just set, 10 to 14 minutes. Remove the cookies from the oven and let them cool for 5 minutes on the baking sheets until transferring them to a wire rack to cool completely.
