Line 2 baking sheets with parchment paper.
In a large bowl, stir together the flour, baking soda, and salt. Set aside.
In another large bowl, mix together the butter, brown sugar, white sugar until blended. Beat in the egg, egg yolk, pure vanilla extract, and peppermint extract until mixed well. Do not over beat!
Stir the dry ingredients into the wet ingredients and keep stirring until the batter is mixed. Then stir in the chocolate chips and chopped candy canes.
Using an ice cream scoop, scoop cookie dough into rounded balls. Dip the balls into the remaining 1/2 cup of crushed candy canes. Place all the balls coated in crushed candies onto the baking sheet lined with parchment paper. Chill the cookies for 30 minutes.
While cookies are chilling, preheat the oven to 325℉.
Bake the cookies for about 10-12 minutes, until the edges begin to harden but the centers are still soft and a bit puffy. Cool cookies on a baking rack and enjoy!
