Can I make the dough ahead of time?
Yes. Refrigerate the dough for up to 48 hours in an airtight container, then bake as directed. You may need to add 1–2 minutes to the bake time if baking from cold.
Why are my cookies spreading too much?
Your butter may be too warm or your dough too soft. Ensure butter is softened but cool, and chill the dough for 15–30 minutes before baking.
Can I substitute the chocolate chips?
Yes. Use dark chocolate chips, milk chocolate chips, or a mix. You can also use chocolate chunks or melted chocolate folded into the dough.
How do I store baked cookies?
Keep cooled cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze baked cookies for up to 3 months.
What if I don't have walnuts?
Walnuts are optional. Omit them entirely, or substitute with chopped pecans, macadamia nuts, or an equal amount of additional chocolate chips.
