Tips for Success
Use room temperature ingredients: Cold eggs can make the dough harder to mix evenly.
Adjust sweetness: If you prefer a less sweet version, reduce the sugar to ¾ cup.
Go for crunchy peanut butter if you love a little texture.
Fork technique matters: Press gently but firmly to create that criss-cross pattern without flattening the cookies too thin.

Storage Recommendations
Room Temperature: Store in an airtight container for up to 5 days. Keep them soft by adding a slice of bread to the container (it keeps the moisture in the cookies).
Freezer: Freeze baked cookies for up to 3 months. Thaw at room temperature or microwave for 10 seconds for that just-baked feel.
Make-Ahead Dough: You can also roll the dough into balls and freeze them. Just bake from frozen, adding 1–2 extra minutes to the baking time.
These cookies travel well too, making them ideal for school lunches, holiday cookie swaps, or cozy gifts wrapped in kraft paper.
