Tips
Chill dough logs thoroughly for clean slicing - soft dough will crush the toffee bits and create uneven cookies
Use a sharp knife to slice through toffee bits cleanly, wiping blade between cuts if needed
Don't overbake - cookies continue cooking on hot pan after removal from oven

FAQ
Can I make the dough ahead of time?
Yes, wrap dough logs tightly and refrigerate up to 3 days or freeze up to 3 months for convenient slice-and-bake cookies.
What if my dough is too soft to shape?
Chill the dough for 30 minutes before shaping, or add flour 1 tablespoon at a time until manageable consistency.
How do I know when cookies are done?
Edges should be lightly golden brown - centers may look slightly underbaked but will finish cooking on the hot pan.
