These Toffee Cookie Bars are a beloved Christmas tradition, made with soda crackers, a homemade toffee mixture, and melted dark chocolate, topped with sea salt.
Preheat oven to 400°F.
Line a baking sheet with parchment paper and arrange club crackers in a single layer.
In a small pot, combine butter and brown sugar. Heat to a boil, stirring constantly, and let it boil for 3 minutes until it gets bubbly and thickens up.
Pour the hot mixture evenly over the club crackers.
Bake for 5-7 minutes.
Remove from oven and immediately add 2 cups dark chocolate chips over the hot crackers.
Return to the oven and bake until the chocolate chips are soft (this should be very brief).
Spread the softened chocolate evenly with a spatula.
Top with a sprinkle of sea salt.
Place the baking sheet in the freezer for a few hours to set completely.
Once firm, break the toffee bars into pieces and enjoy!
