Pro tips

For the crispiest cornflake crunch, ensure your cornflakes are roughly crushed, not pulverized into a fine powder. This preserves the texture. – If your cookies are spreading too much, chill the dough for at least 30 minutes before baking. This helps the butter solidify and prevents excessive spreading.
Store leftover cornflake cookies in an airtight container at room temperature for up to 3 days, or freeze the baked cookies for up to 2 months. Thaw at room temperature or warm gently in the oven for a fresh-baked feel.

These Cornflake Marshmallow Cookies are a true delight, combining nostalgic flavors with an exciting texture. Give this recipe a try and rediscover the joy of a truly unique homemade cookie!
