Gluten-Free No-Bake Nutella Cornflake Cookies
These no-bake cookies combine the beloved flavors of Nutella and cornflakes with mini marshmallows for an irresistibly chewy texture. The simple stovetop method creates a glossy, caramelized coating that binds everything together without any oven time required. Perfect for hot summer days when you want homemade cookies without heating up the kitchen, or when you need a quick treat that kids can help make. The combination of butter, sugar, and corn syrup creates a candy-like base that sets firm at room temperature, while the Nutella adds rich chocolate-hazelnut flavor throughout.

FAQ
Can I use regular marshmallows instead of mini?
Yes, but cut them into smaller pieces first for easier melting and more even distribution throughout the cookies.

The sugar mixture may not have boiled long enough. Return to heat briefly and boil for another 30 seconds before adding remaining ingredients.
How long do these cookies keep?
Store in an airtight container at room temperature for up to one week, though they're best enjoyed within the first few days.
