Preheat your oven to 375 degrees F and line a cookie sheet with parchment paper.

Place a single layer of saltine crackers on the prepared baking sheet, ensuring they cover the entire surface.

In a medium saucepan over medium heat, melt butter and brown sugar. Stir continuously until the mixture comes to a boil. Let it boil for 3 minutes then remove from heat. Stir in the vanilla extract.

Pour the hot toffee mixture evenly over the cracker layer, spreading it with a spatula to coat them completely.

Bake in the preheated oven for 4-6 minutes or until the toffee is bubbling and has a rich, caramel color.

In a small microwave-safe bowl, melt the chocolate chips.

Remove from the oven and immediately pour the melted chocolate over the hot toffee. Spread the melted chocolate evenly with a spatula.

While the chocolate is still soft, sprinkle toppings over the top for a festive finish.

Allow the crack to cool completely then cut into squares. You can speed up the process by placing it in the refrigerator for about 30 minutes. Enjoy!
