Preheat your oven to 350 degrees.

Line a baking sheet with nonstick parchment paper or aluminum foil sprayed with nonstick spray.

Place all of the crackers in a single layer on the baking sheet. You will want to use a large sheet pan, if using a smaller one then you will want to use 2 baking sheets.

In a medium saucepan over medium-high heat stir the butter and sugar until it comes to a boil.

Once it has come to a boil reduce the heat to medium and let it simmer for 5 minutes.

Remove the pan from the heat and slowly pour the brown sugar mixture over the crackers and use a nonstick spatula to carefully spread it across all the crackers.

Place the tray in the oven and bake for 5-6 minutes, keep an eye on it, when it starts bubbling when you want to remove it from the oven.

Remove from the oven and sprinkle the top with the chocolate chips.

Once the chocolate starts to melt using a nonstick spatula spread the melted chocolate across the whole top of the toffee in a thin layer.

Sprinkle the coarse salt on top of the chocolate and add any of the toppings that you are wanting to add.

Let the Christmas Crack completely cool then break into smaller pieces.
