  2. Freeze until solid (about 1-2 hours), then transfer to a freezer-safe bag or container.
  3. When you’re ready to bake, you can either bake them straight from the freezer (adding an extra minute or two to the baking time) or thaw them overnight in the fridge before baking.

What can I substitute for walnuts?
If you need a nut-free option or just want to change things up, you can omit the walnuts entirely. Alternatively, try using pecans or almonds, which will give a different yet equally delightful crunch. If you have nut allergies to consider, leave them out and double the chocolate chips for a rich treat!
