1. Preheat oven to 350°F. Line a large baking sheet with a Silpat baking mat or parchment paper and set aside. 2. Combine flour, salt and baking soda in a medium bowl and set aside. 3. Cream butter and sugars together in a stand mixer fitted with the paddle attachment until combined. Add eggs and vanilla and beat until smooth. Slowly mix in the dry ingredients. Stir in the white chocolate chips, candy canes, and M&M's. 4. Drop heaping tablespoonfuls of dough on prepared baking sheets, about 2 inches apart. Bake for 10-12 minutes or until cookies are golden around the edges, but still soft in the center. Let the cookies cool on the baking sheet for 2 minutes. Transfer cookies to wire rack and cool completely. Note-a few people commented that they made these cookies and they were too puffy and a little dry. You can try reducing the flour to 2 1/2 cups if you have this problem. I used 3 cups of flour though and they were just fine.
