Ingredients for cheerio rice krispie
Six cups of crispy cereal meet buttery marshmallow magic for irresistible treats.
| Ingredient | Amount | Notes |
|---|---|---|
| Rice Krispies Cereal 🍞 | 6 cups | Original flavor preferred |
| Cheerios Cereal 🍪 | 3 cups | Original flavor preferred |
| Large Marshmallows 🍫 | 10 oz | Mini marshmallows work too |
| Unsalted Butter 🧈 | ½ cup | Melted for even coating |
| Vanilla Extract 🌿 | 1 tsp | Pure vanilla preferred |
| Diamond Crystal Kosher Salt 🧂 | ¼ tsp | For balanced seasoning |
| Ground Cinnamon 🌶️ | ½ tsp | Optional for warmth |
| Granulated Sugar 🍚 | 1 tbsp | For extra sweetness |
| Unsweetened Almond Milk 🥛 | 1 tbsp | For extra moisture |
The cereal blend is where texture happens. Rice Krispies provide the classic snap, while Cheerios add subtle sweetness and extra crunch. Grab the original flavors—no honey-nut or frosted versions here. For marshmallows, Big Heart or Kraft brands melt perfectly. If using mini marshmallows, reduce to 8 oz for the same volume. The butter? Unsalted is key—salted can make the treats taste flat. Melt it gently over low heat to avoid burning, then whisk until completely smooth.
No vanilla extract? Vanilla sugar or half a vanilla bean works in a pinch. Running low on almond milk? Oat milk or even water keeps the texture intact. Want more caramel flavor? Add 1 tbsp of brown sugar. For a festive twist, swap 1 cup of Cheerios for Froot Loops or Lucky Charms. The cinnamon is optional but adds warmth—start with 0.25 tsp if you're unsure. If your marshmallows are old or hard, microwave them for 20 seconds to soften before melting.
Butter melts fastest, so prep it first. Line your pan with parchment paper for easy removal—8x8-inch works perfectly. Store treats in an airtight container at room temperature for up to 5 days. For longer storage, freeze individual pieces wrapped in plastic wrap for up to 3 months. Reheat in the oven at 300°F for 5 minutes to restore crispiness. These reheat beautifully, making them perfect for quick snacks or party favors.

Step-by-step instructions for Cheerio Rice Krispie treats
Here's the method for achieving perfectly crispy edges and caramelized cornflake crunch every time.
Melt Butter and Prepare the Marshmallow Mixture
In a large, heavy-bottomed saucepan, combine the 0.5 cup unsalted butter, 10 oz large marshmallows, 1 tbsp granulated sugar, 1 tbsp unsweetened almond milk, 1 tsp vanilla extract, 0.25 tsp diamond crystal kosher salt, and 0.5 tsp ground cinnamon. Place the saucepan over medium-low heat and stir gently with a silicone spatula.
Watch closely as the butter begins to melt, then the marshmallows will start to soften and clump together. Once fully melted, the mixture should reach a smooth, creamy consistency with a glossy sheen. This typically takes about 5-7 minutes—stir constantly to prevent scorching. The mixture should coat the back of a spoon and hold its shape when drizzled, indicating it's ready for the next step.
Combine Cereals and Mix Thoroughly
Remove the saucepan from heat and let the mixture cool for 2-3 minutes—it should be warm but not hot to the touch. In a separate large bowl, combine the 6 cups Rice Krispies cereal and 3 cups Cheerios cereal. Pour the warm marshmallow mixture over the cereals and gently fold everything together using a wooden spoon or silicone spatula.
Work quickly but carefully to distribute the mixture evenly throughout the cereals. You'll notice the Cheerios begin to absorb the caramelized coating, creating those coveted crispy, caramelized pockets. If the mixture feels too dry, add 1-2 teaspoons of warm water to help bind everything together. The goal is to ensure every cereal piece is fully coated and the mixture holds together when pressed.
Press into Pan for Even Crispiness
Lightly grease a 9x13-inch baking dish with nonstick spray or a thin layer of butter. Transfer the cereal mixture into the prepared pan and press down firmly and evenly using a greased spatula or the back of a spoon. Press until the mixture reaches the edges of the pan and forms a smooth, compact layer. This step is critical for achieving crispy edges and preventing crumbly texture.
For extra crispiness, I recommend pressing the mixture in two thin layers. Press the first half into the pan, let it cool and set for 5 minutes, then press the remaining mixture on top. This technique ensures even cooking and a consistent texture throughout. Once pressed, let the treats cool completely in the pan for 1 hour before cutting.
Chill and Cut for Perfect Slices
After pressing, transfer the pan to the refrigerator and chill for at least 1 hour or until fully set. This resting period allows the treats to firm up, making them easier to cut and ensuring clean slices. The longer they chill, the crispier the edges will become.
Once chilled, remove the treats from the pan and cut into 16 even squares using a sharp knife. For extra crispy edges, dip the knife in warm water between cuts to prevent sticking. Serve immediately or store in an airtight container for up to 5 days. The contrast of crispy Cheerios and caramelized Rice Krispies makes these treats irresistibly crunchy with every bite.
Pro Tips For Making Cheerio Rice Krispie
- Melt Butter Slowly: I learned this the hard way—dumping cold butter into a pan and walking away leads to uneven melting and lumpy marshmallow goo. Instead, melt the butter over medium-low heat, stirring occasionally, until it’s fully liquid but not browned. This keeps the mixture smooth and prevents the Cheerios from getting soggy before the marshmallows even melt.
- Toast Cereals Separately: Mixing Rice Krispies and Cheerios raw just to toast them together is a recipe for uneven browning. Toast the Rice Krispies first—they burn faster—then remove them to a plate. Add the Cheerios to the pan for a few seconds until golden, then toss them back in. This guarantees crispy texture without charred bits.
- Skip Pre-Cut Marshmallows: Those tiny pre-sliced marshmallows from the store? They’re convenient, but they turn to gluey paste faster than whole ones. Buy the large marshmallows, cut them into rough chunks (no need to be precise), and they’ll melt evenly without turning the whole batch into a sticky mess. Your future self will thank you—yes, even if you’re impatient like me.
- Stir Like You Mean It: The moment the marshmallows hit the pan, stop stirring and let them melt for 10 seconds—this is non-negotiable. Then, grab a wooden spoon and aggressively scrape the bottom and sides every 15 seconds. The first batch I made sat untouched for too long, and half the Cheerios turned to mush. Keep it moving, and you’ll get that perfect, caramelized crunch.
Serving suggestions for cheerio rice krispie
Caramel Drizzle Finish
Take your treats to the next level by drizzling warm caramel sauce over the top before serving. Heat ½ cup heavy cream with ½ cup granulated sugar until sugar dissolves, then simmer for 3-4 minutes until thickened.
Let cool slightly before drizzling. For extra flair, sprinkle with crushed pecans or sea salt flakes—the salty contrast makes every bite irresistible. 🌟
Fruit Toppings
Brighten up your Cheerio Rice Krispie treats with fresh fruit. Thinly sliced strawberries, bananas, or raspberries add a refreshing crunch and natural sweetness. Arrange them decoratively on top before serving, or press them lightly into the surface for a built-in garnish.
For a tropical twist, try dried pineapple tidbits or mango pieces—just make sure they're dry to prevent sogginess. ✨
Chocolate Dip Variations
Melt ½ cup dark chocolate chips with 1 tbsp coconut oil in a double boiler, then drizzle over cooled treats. For a peanut butter chocolate version, stir 2 tbsp creamy peanut butter into the melted chocolate before drizzling.
Let the chocolate set slightly before serving—it adds a rich, decadent layer that pairs perfectly with the cereal crunch. 🍫
Warm Spiced Milk Pairing
Serve your treats with a warm cup of spiced milk for the ultimate cozy experience. Heat 1 cup whole milk with ½ tsp cinnamon, ¼ tsp vanilla extract, and a pinch of nutmeg until steaming.
The warm spices complement the caramelized cereal, creating a nostalgic dessert experience that feels like a hug in a bowl. 🥛
Mini Treat Bites
For a fun twist, press the mixture into mini muffin tins lined with parchment paper. Use 1 tablespoon of mixture per tin and chill for 15 minutes before removing.
These bite-sized treats are perfect for parties, lunchboxes, or snacking on the go. Add a sprinkle of colored sugar or mini M&M's for extra fun. 🍪
Ice Cream Sandwiches
Cut your Cheerio Rice Krispie treats into rectangles and sandwich them around a scoop of vanilla ice cream or coffee ice cream. Secure with a toothpick and serve immediately for a delightful, no-bake dessert.
For extra indulgence, dip the edges in melted chocolate before assembling. This twist turns your treats into a creamy, crunchy masterpiece. 🍦

Frequently asked questions
Can I make these treats without marshmallows?
Not recommended, as marshmallows create the signature gooey texture. For a substitute, try 1 cup melted white chocolate or ½ cup honey mixed with ½ cup butter—though the texture will be slightly different. The marshmallow mixture is key for that classic Rice Krispie treat consistency.
Why are my treats too crumbly?
Crumbly treats usually mean the marshmallow mixture cooled too much before pressing. Keep the mixture warm but not hot when combining with cereals, and work quickly. If needed, add 1-2 teaspoons of warm water—just enough to help the mixture bind without making it soggy.
Can I use a different cereal besides Cheerios?
Try Froot Loops, Lucky Charms, or even crushed graham crackers—each adds a unique flavor and texture. For a nutty twist, swap 1 cup of Cheerios for chopped pecans or walnuts. Just ensure your total cereal volume stays at 9 cups—adjust other cereals accordingly.
How do I store these treats for maximum freshness?
Keep them in an airtight container—they stay fresh for 5 days at room temperature. For longer storage, freeze individual pieces wrapped in plastic for up to 3 months. To restore crispiness after thawing, warm at 300°F for 5 minutes.
Can I make these treats ahead of time?
Yes! These treats actually taste better after sitting overnight as the flavors meld. Press the mixture into the pan, chill for 1 hour**, then store covered at room temperature. The edges will crisp up even more over time—perfect for meal prep or gifting!
