Making Chocolate Toffee Crack is straightforward. Follow these simple steps to create this delightful dessert:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).
2. Prepare Baking Sheet: Line a baking sheet with aluminum foil and spray it with non-stick cooking spray for easy removal.
3. Arrange Crackers: Lay the saltine crackers in a single layer on the prepared baking sheet, covering the entire surface.
4. Make Toffee Mixture: In a saucepan over medium heat, melt the butter and brown sugar together, stirring constantly until it comes to a boil.
5. Boil the Mixture: Once boiling, let it boil for 3 minutes without stirring. Remove from heat.
6. Pour Over Crackers: Immediately pour the hot toffee mixture over the arranged saltine crackers, spreading it evenly with a spatula.
7. Bake: Place the baking sheet in the preheated oven. Bake for 5-7 minutes, or until the toffee is bubbly.
8. Add Chocolate Chips: Remove from the oven and sprinkle the chocolate chips evenly over the hot toffee. Let them sit for a couple of minutes until melted.
9. Spread Chocolate: Using a spatula, spread the melted chocolate evenly over the toffee layer.
10. Add Nuts: If using nuts, sprinkle them on top of the melted chocolate, pressing them down gently.
11. Cool: Allow the entire pan to cool at room temperature for about 30 minutes, then place it in the refrigerator for 1 hour to set completely.
12. Break Apart: Once set, break the Chocolate Toffee Crack into pieces and serve.
