This recipe comes from my moms recipe book, and they are so good! One of my dad’s favorites that she makes. I love how they they are and they never last long at her house. The marshmallow and cornflakes together are absolutely divine. I am so excited to share these with you.

When making these delicious Marshmallow Cornflake Cookies please make sure you refrigerate the dough. IF you don’t it will be a mess on the pan ¬†because these cookies do love to spread…but that is what makes them oh so good! I can’t wait for you to try them!

One of the great things about Marshmallow Cornflake cookies is their versatility. You can add nuts, chocolate chips, or other candies to the mixture to create your own unique flavor profile. Try making a big batch of these treats and freezing them for later use. Just pop a few in the microwave for a few seconds and enjoy a warm and gooey cookie anytime you want!
