Line 2-9"x13"x2" baking pans with parchment paper.

Preheat your oven to 350 degrees F.

In a medium mixing bowl combine the flour, cocoa, baking soda, and salt. Stir to combine and set aside.

In the bowl of a large stand mixer or large mixing bowl combine the white sugar, brown sugar, and butter. Mix until well combined.

Add the eggs and vanilla. Mix until well combined.

While mixing on a slow speed add the flour mixture a little at a time, mixing well between each addition, until all of the flour mixture is well incorporated into the wet ingredients. (Scrape the sides of the bowl between additions of the flour mixture.)

Divide the batter evenly between your lined pans and spread it out evenly in each pan.

Top each pan of batter with ¼ of the bag of milk chocolate chips, ¼ of the bag of dark chocolate chips, and 1 oz. of the crushed candy canes.

Bake at 350 degrees for 45 minutes.

Remove the pans from the oven and top them each again with ¼ of the bag of milk chocolate chips, ¼ of the bag of dark chocolate chips, and 1 oz. each of the crushed candy canes. (The chocolate and candy will melt and stick to the top of the bars while holding shape.)

Let bars cool completely in the pans before cutting into squares.

When the bars are cool lift them from the pans by the edges of the parchment paper. Cut and EAT!!!
