I developed this no-bake treat after spotting colorful cereal at Walmart, inspired by childhood memories of kitchen experiments. The combination of Fruity Pebbles and marshmallows creates a vibrant, crunchy texture that’s impossible to resist.
This recipe uses just 4 ingredients and comes together in under 15 minutes, making it perfect for last-minute gatherings or satisfying a sweet craving. The cereal stays crisp while the marshmallow mixture binds everything together.
The result is a batch of squares with a rainbow of colors and that signature Rice Krispy snap. Each bite delivers sweet marshmallow flavor with the fruity cereal’s bright crunch.
No oven required—just melt, mix, and set. Ideal for parties, lunchboxes, or an easy dessert solution.
Ingredients for Fruity Pebbles Rice Crispy Treats Walmart
Four ingredients deliver vibrant color and that signature crunch in every bite.
| Ingredient | Amount | Notes |
|---|---|---|
| Fruity Pebbles Cereal 🥣 | 6 cups | Colorful, crisp variety required |
| Mini Marshmallows 🍬 | 10 oz | Regular size works too |
| Unsalted Butter 🧈 | ¼ cup | For melting with marshmallows |
| Pinch of Salt 🧂 | 1 pinch | Enhances sweetness balance |
The cereal is key here. Walmart’s store-brand Fruity Pebbles work just as well as name-brand (Post), and you’ll find them in the cereal aisle. Look for bright, uniform colors—pale pieces mean stale cereal. The marshmallows need to be fresh too; old ones turn hard and won’t melt smoothly. Jet-Puffed or Kraft are reliable choices widely available.
No Fruity Pebbles? Any colorful cereal works—Trix, Fruit Loops, or even a mix. Need to avoid gelatin? Dandies brand marshmallows are vegan and melt beautifully. Short on time? Pre-melted marshmallow fluff (one 7-oz jar) replaces the marshmallows and butter entirely. The salt is optional but recommended—it cuts the sweetness.
Store these in an airtight container at room temperature for up to 5 days (if they last that long). They soften slightly over time but stay delicious. For longer storage, freeze for up to 3 months—thaw at room temperature before serving.

Step-by-Step Instructions for Fruity Pebbles Rice Krispy Treats
This method ensures vibrant color and perfect texture with every batch of this beloved treat.
Step 1: Prepare the Baking Dish and Measure Ingredients
Begin by lightly greasing an 8×8-inch or 9×9-inch baking dish with nonstick cooking spray or a thin layer of the 0.25 cup Unsalted Butter. This prevents the finished treats from sticking and makes cutting easier. I prefer using a silicone brush to apply the butter evenly across the bottom and sides of the dish.
Measure out the 6 cups Fruity Pebbles Cereal and set it aside in a large mixing bowl. Also have the 10 oz Mini Marshmallows and 1 pinch Pinch of Salt ready to go. Organization is key here—once the marshmallow mixture is ready, you’ll need to work quickly before it sets.
Step 2: Melt Butter and Toast Marshmallows
In a large, heavy-bottomed pot, melt the remaining 0.25 cup Unsalted Butter over low heat. The slow melt ensures the butter doesn’t brown or burn, which would impart unwanted flavors to your treats. Add the 1 pinch Pinch of Salt to the melted butter and stir to dissolve completely.
Once the butter is fully melted, add all 10 oz Mini Marshmallows at once. Stir constantly with a heatproof spatula or wooden spoon, scraping the bottom of the pot to prevent sticking. The marshmallows will melt gradually, becoming smooth and glossy. This process typically takes 5-7 minutes on low heat—higher heat risks burning the mixture.
Remove the pot from heat as soon as the marshmallows are completely melted and the mixture is smooth. You’ll notice it pulling away slightly from the sides of the pot when it’s ready.
Step 3: Combine Marshmallow Mixture with Cereal
Immediately pour the melted marshmallow mixture over the 6 cups Fruity Pebbles Cereal in your large bowl. Using the same spatula, fold the cereal into the marshmallow mixture with a gentle but firm motion. The goal is to coat every piece of cereal evenly without crushing the Fruity Pebbles.
Work quickly but carefully—the mixture will begin to set as it cools. You’ll know it’s properly combined when every cereal piece glistens with the marshmallow coating and the colors look vibrant and evenly distributed. This usually takes 30-45 seconds of folding.
Step 4: Press and Set in the Prepared Dish
Transfer the coated cereal mixture to your prepared baking dish. Using your spatula or the back of a greased spoon, press the mixture firmly and evenly into the dish. I find that pressing down gently with my fingertips (lightly buttered to prevent sticking) helps create an even top layer without compacting the treats too much.
Ensure the mixture reaches all corners of the dish and the top is smooth and level. The pressure you apply now determines the density of your final treats—press too hard and they’ll be compact; too light and they may fall apart when cut. Allow the treats to set at room temperature for 1-2 hours or until completely cool and firm to the touch.
Step 5: Cut and Serve the Finished Treats
Once fully set, use a sharp knife to cut the treats into squares. For clean cuts, I recommend dipping the knife in hot water between each slice. This prevents the marshmallow from sticking to the blade and dragging the cereal with it.
Cut into 16 equal squares for standard serving sizes, or larger pieces if you prefer. The treats should hold their shape perfectly, with the Fruity Pebbles maintaining their vibrant colors and slight crunch. Serve immediately or store in an airtight container at room temperature for up to 3 days.
Pro Tips For Making Fruity Pebbles Rice Crispy Treats Walmart
- Melt Butter Low: Use medium-low heat when melting the butter for your marshmallows—I learned this the hard way after burning two batches at high temperatures.
- Press While Warm: Spread the mixture into the pan and press it down immediately while the marshmallows are still warm and pliable, or it’ll harden too fast to shape.
- Skip Cheap Marshmallows: Mini marshmallows melt smoother and faster than large ones, and the cheap brands just don’t hold the shape as well.
- Butter Your Spoon: Coat your spoon or spatula in a little extra butter before pressing the mix down—it keeps everything from sticking and makes cleanup a breeze.
Essential Equipment for This Recipe
Large Mixing Bowl
A 3-4 quart mixing bowl gives you enough space to fold the cereal and marshmallow mixture without spills. I use my Pyrex glass bowl from Walmart—it’s durable and easy to clean. The wide surface helps distribute the marshmallow coating evenly. 💛
Heavy-Bottomed Pot
Use a 3-4 quart pot with a thick base to melt butter and marshmallows evenly. A nonstick pot prevents sticking and makes cleanup simple. I found mine at Walmart for under $20—perfect for this recipe and other stovetop tasks.
Heatproof Spatula
A silicone spatula is essential for stirring marshmallows and pressing the mixture into the pan. It withstands heat and scrapes every bit of melted marshmallow from the pot. I keep a red silicone spatula just for baking projects like this.
8×8-Inch Baking Dish
An 8×8-inch glass baking dish creates the perfect thickness for these treats. I grease mine with a thin layer of butter before adding the mixture. The glass lets you see the vibrant colors as they set, and it’s easy to find at Walmart.
Sharp Chef’s Knife
Use a sharp 8-inch chef’s knife to cut clean squares. Dip it in hot water between cuts to prevent sticking. I’ve had my Mercer Culinary knife for years—it’s a budget-friendly workhorse for all my kitchen tasks.
Optional: Parchment Paper
Line your baking dish with parchment paper for easy removal and cleanup. It prevents sticking and lets you lift the entire batch out to cut on a cutting board. Walmart’s store brand works just as well as name brands. 💡

Frequently Asked Questions
Can I use regular Rice Krispies instead of Fruity Pebbles?
Yes, but the texture and color will differ. Regular Rice Krispies create classic treats, while Fruity Pebbles add vibrant colors and a fruit-flavored crunch. For best results, stick with Fruity Pebbles for this recipe.
How do I keep the treats from getting too hard?
Press the mixture lightly into the pan—too much pressure makes them dense. Also, avoid overcooking the marshmallow mixture. 1-2 hours setting time at room temperature ensures perfect texture.
Can I make these ahead of time?
Store in an airtight container at room temperature for up to 3 days. For longer storage, freeze for up to 3 months and thaw at room temperature before serving.
What if my marshmallows won’t melt smoothly?
Use fresh marshmallows and melt over low heat, stirring constantly. Old marshmallows turn hard and resist melting. If needed, add 1 teaspoon of water to help soften them.
