Chef’s Notes & Pro Tips for Flawless Results
- Make-Ahead: These cookies can be made in advance and stored for later enjoyment; they taste even better after a day in the fridge.

- Using Old Cornflakes: Stale cornflakes can impact the texture. Always use fresh cereal.
- Mismeasuring Ingredients: Accurate measurements are key; always level off dry ingredients.

- Skipping Salt: It plays a crucial role in enhancing overall flavor. Don’t overlook it!
Creative Variations & Customizations
