FAQ
Can I use natural peanut butter instead of creamy?
Yes, but stir the oil in thoroughly or the mixture may be too wet. Use the same quantity and expect slightly less structure.
What if my air fryer cooks faster than 6-8 minutes?
Start checking at 4-5 minutes. Air fryer temperatures and sizes vary significantly. Cookies should have golden edges but soft centers when done.
How long do baked cookies keep and can I freeze them?
Store in an airtight container at room temperature for up to 5 days. Freeze baked cookies up to 1 month or freeze dough portions up to 1 month before cooking.
