Notes
To make these Peanut Butter Cornflake Cookies gluten free, use certified gluten-free cornflakes.
Verify that the peanut butter, mini marshmallows, peanut butter chips, salted butter, and oil are labeled gluten free.
Check the cornflake cereal carefully, as many standard cornflake brands contain malt flavoring or may have gluten cross-contact.
Use clean cookware, measuring cups, spatulas, scoops, parchment paper, and baking sheets to prevent gluten cross-contact.
If preparing for someone with celiac disease, use dedicated gluten-free tools and avoid shared containers of peanut butter or marshmallows that may have been exposed to gluten.
Allow the cookies to set fully before serving, as gluten-free cornflakes may soften slightly faster than traditional cornflakes.
