Ingredient breakdown: key components

Step-by-step guide to no bake cornflake cookies
- Gather your equipment: a large mixing bowl, a saucepan, a spatula, and a parchment-lined tray. The bowl is for mixing, saucepan for melting marshmallows and butter, spatula for folding, and tray to set the cookies.
- In the saucepan, melt 1/2 cup (115g) butter over low heat. Keep the heat gentle; bright melting means it’s ready. Stir occasionally until fully melted, about 2-3 minutes.
- Add 10 oz (about 40 large) marshmallows to the melted butter. Stir continuously until they’re completely melted and gooey, about 3-4 minutes. The smell of toasted marshmallows should fill the air.
- Remove from heat. Quickly pour in 4 cups (about 150g) cornflakes. Fold gently with the spatula, pressing down to coat all the flakes evenly. Watch for the cereal to stay crispy but coated in sticky marshmallow goo.
- Scoop spoonfuls of the mixture onto the parchment-lined tray. Use the back of the spoon or a small ice cream scoop for uniformity. Slightly press each cookie to flatten if desired.
- Let the cookies rest at room temperature for about 30 minutes. They’ll firm up and set, with a shiny, sticky exterior and crunchier edges. If in a hurry, refrigerate for 15 minutes.
- Once set, check the texture: cookies should hold shape but still be chewy inside. The appearance should be glossy and slightly crackled. If they’re too soft, give them more time to firm up.
- Enjoy your no-bake cornflake cookies, feeling the crunchy exterior give way to gooey marshmallow. Store leftovers in an airtight container at room temp for up to 3 days.

Notes
Tips & Tricks for Perfect Cookies
- Use fresh marshmallows for maximum gooeyness—older ones can be dry and less sticky.
- Melt butter and marshmallows over low heat—bright bubbling indicates perfect melting, avoid high heat to prevent burning.
- Fold cereal gently—overmixing can crush flakes, preserving crunch is key for texture.
- Chill the mixture slightly before scooping—this helps the cookies hold shape better when setting.
- Press the cookies lightly with the back of a spoon—this ensures even thickness and compactness.
- Let the cookies rest at room temperature—about 30 minutes until they’re firm and glossy, no rush to refrigerate.
- Add a pinch of salt or vanilla—enhances sweetness and depth, don’t skip the flavor boost.
Common mistakes and how to fix them
- FORGOT to check marshmallow melt → Use low heat and stir constantly to prevent burning.
- DUMPED in too many cereal → Add cereal gradually, folding gently for even coating.
- OVER-TORCHED the butter mixture → Remove from heat immediately if smell turns smoky or color darkens.
- MISSED the resting step → Let cookies cool and set at room temperature for best texture.
Quick fixes and pantry swaps
- If marshmallows seize or burn, splash in a little cold water to stop the melting.
- When cookies stick to parchment, grease the paper lightly or use a silicone mat.
- Splash a few drops of vanilla or water if the mixture feels too dry or crumbly.
- Patch over cracks by gently pressing the mixture back together while still warm.
- Shield from humidity by storing in an airtight container; moisture makes them lose crunch.
Prep, store, and reheat tips
- You can prepare the mixture a day in advance; keep it covered in the fridge to prevent drying out, and it will stay fresh and sticky.
- Store the finished cookies in an airtight container at room temperature for up to 3 days; the edges stay crisp, and the marshmallow retains its chewy texture.
- Refrigerate for 15-20 minutes if you want a firmer cookie; the coolness intensifies the marshmallow flavor and makes them easier to handle.
- Gently reheat leftovers in the microwave on low power for 10-15 seconds if the marshmallow feels too stiff; the smell of toasted marshmallow and butter will refresh beautifully.
