What is Rice Krispies Cereal?
Before we dive into the recipe, let’s take a moment to talk about the cereal that started it all: Rice Krispies. A household name since 1928, Rice Krispies is a classic breakfast cereal made from crisped rice, sugar, and a dash of salt. It’s loved for its light and crunchy texture, which holds up well when mixed into marshmallow treats. But Rice Krispies cereal isn’t just limited to breakfast — it has found its way into the hearts and kitchens of bakers everywhere, serving as a base for everything from homemade bars to cake pops and beyond.
Though originally marketed as a healthy breakfast option, the invention of Rice Krispies Treats in the 1940s transformed this simple cereal into something much more indulgent. The combination of crispy cereal and gooey marshmallows has become an American favorite that transcends generations.
Now, let’s talk about the twist we’re adding to this classic recipe: colorful cereal! Think about the possibilities — adding cereals like Froot Loops, Lucky Charms, or even Cocoa Pebbles to the mix can add a whole new layer of texture and fun to your Rice Krispies Treats.
Ingredients and Prep
To get started, you’ll need the following ingredients. These are all easy to find and most likely already stocked in your pantry!
Ingredients:
- 6 cups of Rice Krispies cereal – This is the foundation of your treats and gives them that perfect crispy crunch.
- 2 cups of colorful cereal (such as Froot Loops, Lucky Charms, or any cereal with fun shapes or colors) – Adding a colorful twist to your treats, making them visually appealing and extra fun!
- 5 cups of mini marshmallows – These provide the essential gooey sweetness that binds everything together.
- 1/4 cup of unsalted butter – For the rich, buttery flavor that makes these treats melt in your mouth.
- 1/2 tsp vanilla extract (optional) – Adds a subtle depth of flavor.
- A pinch of salt – Balances the sweetness of the marshmallows.
- Optional add-ins: chocolate chips, peanut butter, crushed candy bars, sprinkles, or even dried fruit for a unique twist!
Prep Time and Cook Time:
- Prep time: 10 minutes (getting your ingredients and tools ready)
- Cook time: 5 minutes (melting marshmallows and butter)
- Total time: 15-20 minutes (cooling and cutting into bars)

Step-by-Step Instructions
Step 1: Melt the Butter and Marshmallows
In a large saucepan over medium-low heat, begin melting the butter. As the butter begins to melt, add the marshmallows, stirring constantly. Be patient and keep stirring to ensure the marshmallows melt evenly and smoothly. This process takes only a few minutes, but be careful not to overheat it, or the marshmallows could burn and become gritty. Once everything is melted together into a smooth, gooey mixture, remove the pan from the heat.
Step 2: Mix the Cereals
Now it’s time to add the fun part! Pour in your Rice Krispies cereal and your colorful cereal. Stir gently with a spatula to make sure the marshmallow mixture evenly coats all the cereal. It’s important to mix everything carefully to avoid crushing the cereal and losing that delicious crunch.
Step 3: Press the Mixture Into a Pan
Next, grab a 9×13-inch baking dish and line it with parchment paper or lightly grease it with butter. Pour your cereal and marshmallow mixture into the dish, spreading it out evenly. Now comes the tricky part: pressing it down. You don’t want to press too hard, or the bars will be too compact. Aim for a light and even press, ensuring that all the cereal is nestled tightly together to form solid, but not hard, bars.
Step 4: Let It Set
Allow the treats to cool at room temperature for about 30 minutes. You’ll know they’re ready when the bars feel firm to the touch. If you’re in a rush, you can pop the pan in the refrigerator for about 15 minutes to speed up the process.
Step 5: Cut and Serve
Once the treats have set and firmed up, it’s time to cut them into squares or rectangles. Use a sharp knife to slice them into even pieces, and voilà — you have a batch of Rice Krispies Treats Cereal Bars ready to enjoy!

Tips and Tricks for the Perfect Rice Krispies Treats
Creating the perfect Rice Krispies Treats requires a bit of care. Here are some tips to ensure your treats are a hit:
- Use fresh marshmallows: Fresh marshmallows melt more smoothly and create that signature chewy texture. If your marshmallows have been sitting in the pantry for a while, they may not melt as well.
- Don’t over-melt: Keep an eye on the marshmallows and butter as they melt. Overheating the mixture can cause it to become too hard when it sets.
- Press lightly: When pressing the mixture into the pan, don’t overdo it. Press too hard, and you’ll end up with dense, hard treats instead of light, chewy bars.
- Add extra flavor: Feel free to mix things up! You can add peanut butter to the marshmallow mixture for a richer taste, or drizzle melted chocolate on top for an extra layer of sweetness.
How to Make This Recipe Your Own
The beauty of Rice Krispies Treats is how easily they can be customized. Here are some fun ideas for making these treats even more special:
1. Holiday-Themed Treats
One of the easiest ways to make these treats more festive is to incorporate seasonal colors and flavors. For Christmas, try adding green and red cereals or some crushed peppermint candy. For Halloween, a mix of orange and black cereals, along with a sprinkle of edible glitter, can make your treats extra spooky!
2. Flavor Additions
Want to make these Rice Krispies Treats extra indulgent? Try adding different flavorings to the marshmallow mixture. A spoonful of peanut butter or Nutella will make these bars even more decadent. Or, for a sweet and salty twist, sprinkle some crushed pretzels or toffee bits on top before pressing them down.
3. Mix-ins and Toppings
For even more variety, consider mixing in other fun additions like chocolate chips, M&Ms, or even chopped-up candy bars. You could also sprinkle rainbow-colored sprinkles on top for an added burst of color.
