Preheat oven to 350 degrees.
Unwrap candy canes, insert in a freezer zip lock bag, and beat with a meat mallet until the bits are the size you want.
Line a cookie sheet (with four sides) with tin foil and liberally spray it with cooking spray.
Line the cookie sheet with the saltines, spacing them as close together as you can.
Melt the butter in sauce pan, then add the brown sugar. Stir constantly on medium high for exactly 5 minutes.
Pour the sugar mixture evenly over the crackers. Realign the crackers with a fork as needed.
Put in the oven for 3-5 minutes. Remove and sprinkle with mini chocolate chips.
Return to oven for 1 minute. Remove and spread out chocolate chips with a spatula. Sprinkle with kosher salt and candy cane bits to taste.
Put in freezer for 30 minutes to harden. Remove and break into cracker-size pieces.
