Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Place the Saltine crackers in a single layer on the prepared baking sheet.

In a medium saucepan, melt the butter and brown sugar over medium heat, stirring frequently until boiling.

Let the mixture boil for 3 minutes without stirring.

Carefully pour the hot toffee mixture over the crackers, spreading it evenly.

Bake in the preheated oven for 10 minutes.

While the crackers are baking, melt the white chocolate chips in a microwave-safe bowl in 30-second intervals, stirring in between.

Once the crackers are out of the oven, immediately drizzle melted white chocolate over the top.

Use a spatula to spread it evenly over the crackers.

Allow the Christmas Crack to cool completely at room temperature.

Once set, break it into pieces and enjoy.
