Preheat oven to 400°F and line a baking sheet with parchment paper.
Arrange the saltine crackers in a single layer.
In a saucepan, melt butter and brown sugar together, bringing it to a gentle boil. Pour evenly over the crackers.
Bake for 5 minutes.
Remove from oven, sprinkle chocolate chips on top, and let them melt slightly before spreading evenly.
Add a few drops of Candy Cane Flavour, top with crushed candy canes, and refrigerate for 1 hour (if you can wait that long).
Break into pieces, serve, and prepare to make another batch — you’ll want to.
