Viral Cornflake Christmas Wreath Cookies: Easy No-Bake Holiday Treat

Every holiday season, one no-bake cookie blows up on TikTok and Pinterest, and this year it is the cornflake Christmas wreath cookie. Crisp corn flakes are folded into gooey marshmallow, tinted a festive green, and shaped into little wreaths dotted with red candy "holly berries." They look like tiny edible Christmas wreaths, taste like the classic marshmallow treats everyone grew up with, and take barely 20 minutes from start to finish. No oven, no mixer, no rolling pin — just one pot and a sheet pan.

These wreath cookies are the ultimate last-minute holiday baking project for people who do not want to actually bake. Kids love pressing the red berries on top, and the cookies firm up fast enough to package for cookie exchanges, teacher gifts, and dessert tables. They also keep beautifully for weeks, which means you can make a big batch early in December and have festive treats ready for every party, potluck, and surprise guest.

This recipe sticks close to the viral version but with a few tested tweaks: a touch of vanilla and salt to round out the sweetness, and a shaping trick that keeps the wreaths neat instead of lumpy. Follow the steps exactly and you will get crisp, chewy, bakery-window wreaths every time.

Ingredients

• 1/3 cup (75 g) unsalted butter
• 1 package (10 oz / 283 g) mini marshmallows (about 5 1/2 cups)
• 1 1/2 teaspoons green gel food coloring (or 2 teaspoons liquid green coloring)
• 6 cups (about 160 g) corn flakes cereal
• 54 small red cinnamon candies (Red Hots), or substitute red mini M&Ms (3 per wreath)
• 1/2 teaspoon vanilla extract (optional but recommended)
• Pinch of fine sea salt

Instructions

1. Prep your station. Line two large baking sheets with parchment paper. Have the red candies counted out in a small bowl, and rub a little butter on your fingertips or wear food-safe gloves — the mixture is sticky.
2. Melt the marshmallow base. In a large saucepan over medium-low heat, melt the butter completely. Add the mini marshmallows and stir constantly with a heatproof spatula until they are fully melted and smooth, about 3 minutes. Remove from the heat.
3. Color and flavor. Stir in the green food coloring, vanilla extract, and the pinch of salt until the color is even. Start with a little less coloring and add more until you reach a rich pine green — remember the corn flakes will lighten the color slightly.
4. Fold in the cereal. Add the corn flakes all at once and fold quickly but gently until every flake is coated. Work fast here — the mixture begins to set as it cools.
5. Shape the wreaths. Scoop out 2-tablespoon mounds onto the parchment-lined sheets. While each mound is still warm and pliable, use your lightly greased fingers to press it into a ring shape, making a hole in the center like a wreath. Work one mound at a time.
6. Add the berries. Immediately press 3 red candies into the top of each wreath in a small cluster, like holly berries. The warm marshmallow will hold them in place as it sets.
7. Let them set. Leave the wreaths at room temperature for 15 to 20 minutes, until firm and no longer tacky to the touch. Makes about 18 wreath cookies.

Tips for Perfect Wreath Cookies

Use fresh marshmallows. Older marshmallows melt unevenly and make the cookies too firm. Fresh mini marshmallows melt the fastest and give the chewiest texture.

Gel coloring beats liquid. Gel gives a deep, rich green without thinning the marshmallow mixture. If you only have liquid coloring, add it gradually and expect a slightly lighter green.

Keep your hands greased. A thin coat of butter or cooking spray on your fingertips makes shaping fast and frustration-free. Reapply every few wreaths.

Work in batches if needed. If the mixture firms up before you finish shaping, return the pan to very low heat for 30 seconds, stirring, to soften it again.

Skip the cinnamon candies for kids. Red Hots have a spicy bite some kids do not love — red mini M&Ms or small red jelly candies make a friendlier "berry."

Make-Ahead & Storage

These wreath cookies are a dream make-ahead treat. Store them in an airtight container at room temperature with parchment paper between layers, and they stay crisp and chewy for up to 2 weeks. For gifting, shape them up to 2 days ahead so they look their freshest. Freezing is not recommended — the marshmallow texture turns crumbly and the colors can bleed. If you need to soften slightly firm cookies, 8 seconds in the microwave brings back the chew.
