Creating Classic Christmas Toffee is easy when you follow these simple steps:

1. Prepare the Baking Sheet: Line a baking sheet with parchment paper and set aside.
2. Melt Butter: In a medium saucepan over medium heat, melt the butter.
3. Add Ingredients: Once melted, add the sugar, corn syrup, and salt to the saucepan. Stir continuously to combine.
4. Cook Mixture: Continue to cook while stirring constantly until the mixture reaches a golden-brown color. This usually takes about 15 minutes.
5. Check Temperature: For the best results, use a candy thermometer to monitor the temperature—it should reach 300°F (149°C).
6. Stir in Vanilla: Remove the saucepan from heat and quickly stir in the vanilla extract.
7. Pour and Spread: Carefully pour the toffee mixture onto the prepared baking sheet. Use a spatula to spread it into an even layer.
8. Top with Chocolate: Immediately sprinkle the chocolate chips on top. Let them sit for a few minutes, then spread melted chocolate over the toffee.
9. Add Nuts: Sprinkle the chopped nuts onto the melted chocolate, pressing gently to ensure they stick.
10. Cool: Allow the toffee to cool completely at room temperature for about 30 minutes, or until firm.
11. Break into Pieces: Once cooled, break the toffee into pieces for serving.

By following these straightforward steps, you’ll have a delicious batch of Classic Christmas Toffee that can enhance your holiday celebrations!
