Preheat your oven to 350°F (175°C).
In a mixing bowl, whisk together the flour, baking soda, and salt; set aside.
In a large bowl, cream together the softened butter, granulated sugar, and powdered sugar until light and fluffy.
Add the egg and peppermint extract, and mix until fully combined.
Gradually add the dry mixture to the wet ingredients, mixing until just combined.
If using, divide the dough and mix in a few drops of red gel food coloring into half the dough.
Take teaspoons of each dough and roll them into logs, then twist them together to form a spiraled shape.
Place the formed cookies on a baking sheet lined with parchment paper, spacing them about two inches apart.
Sprinkle crushed candy canes over the top of each cookie before baking.
Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden.
Allow cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack.
