How to Store

Helpful Cooking Tips
- Experiment with the texture! If you prefer chewier cookies, underbake them slightly. For crunchier cookies, let them bake a little longer.
- Don’t skip the flattening step — it helps ensure even baking, so you don’t end up with uneven cookies.
- If you plan to use dry mix-ins like nuts or dried fruit, consider chopping them into smaller pieces for better distribution throughout the cookies.
Recipe Variations
Why not switch things up? Consider adding some mashed ripe banana for natural sweetness or swap the cinnamon for cocoa powder for a chocolate version. You can also incorporate spices like nutmeg or ginger for a seasonal touch, or even try nut-free butter alternatives to cater to allergies.
