You know that feeling when you’re rummaging through the pantry, half-hungry and dreaming of something sweet and crunchy, but you really don’t want to fire up the oven? That was me one sweltering July afternoon last year. I’d promised my granddaughter “cookies that look like unicorn rainbows,” and the moment I said yes, I went straight into panic mode—until I remembered the box of Fruity Pebbles hiding on the top shelf. Life (and snack time) was saved.
These Fruity Pebbles Cookies are pure nostalgia in your hand: bright cereal clusters wrapped in melty marshmallow, shaped into cute little rounds. No baking required, just a quick stir, a bit of pressing, and—boom—you’ve got a tray of cheery, craveable treats that both kids and grown-ups go wild for.
Why You’ll Love This Recipe
- No oven needed—just a saucepan and spatula (seriously, it’s that easy!).
- Ready in under 30 minutes including chill time—perfect for last-minute parties.
- Rainbow crunch that makes every bite feel like a celebration.
- Uses pantry staples plus a box of Fruity Pebbles you probably already have.
- Light on butter but big on sweet, gooey marshmallow goodness.
- Kiddos beg for these; adults can’t resist sneaking a few when nobody’s looking.
- Vegan and gluten-free swaps make it allergy-friendly—yes, really!
- Easily doubled or tripled when you need a crowd-pleaser for bake sales.
Ingredient Notes
- Fruity Pebbles: I recommend Kellogg’s for the brightest, cheeriest colors. Want extra crunch? Add up to 1 cup of crisp rice cereal (Rice Krispies works great).
- Butter or coconut oil: Just ¼ cup (½ stick). If you’re dairy-free, swap in solid coconut oil—tastes surprisingly close!
- Mini marshmallows: About 8 ounces (roughly 4 cups). Vegan marshmallows are your friend if you need a plant-based version.
- Vanilla extract: A half-teaspoon of pure stuff really brings out that cozy sweetness.
- Sea salt: Just a pinch to balance all that sugary fun.
- Nonstick spray or parchment: A little oil or paper keeps your hands (and scoop) from turning into a gooey mess.
Tip: For an extra snap, pop your cereal in the freezer for 10 minutes before mixing. It helps those little rice bits stay crisp even under all that marshmallow hug.
Directions
- Prep your station: Line a baking sheet with parchment paper or lightly spray it. You’ll thank yourself later when cleanup is a breeze.
- Melt the fat: Over low heat in a medium saucepan, stir your butter (or coconut oil) until it’s just melted—no browning, please! Too much heat, and the marshmallows can seize up on you.
- Add marshmallows: Toss in all those mini puffs and stir constantly. When you still see a few tiny marshmallow bits, take the pan off the heat—they’ll finish melting in their own time.
- Flavor boost: Quickly stir in the vanilla and salt. This teeny pinch of salt is what turns sweet into sublime.
- Mix in the cereal: Pour in your Fruity Pebbles (and optional crisp rice). Gently fold with a silicone spatula—no pulverizing, just enough to get every flake coated in gooey goodness. (I like to spray the spatula first so it slides right through.)
- Shape the cookies: Let the mixture rest for 1–2 minutes so it’s cool-ish but still pliable. Then use a 2-tablespoon scoop or your greased hands to form rounds about 1 inch apart on the sheet. Don’t skip letting it cool a bit—hot marshmallow will burn little fingers (or melt your gloves).
- Chill to set: Pop the tray into the fridge for 15–20 minutes. This is where chew meets crunch and magic happens.
- Enjoy: Once they’re firm, dig in! Or pack them up for later (see tips below).
Quick aside: If your first batch feels too sticky, just chill them a few minutes longer. Patience is a virtue—even for cookies.
Variations & Flavor Twists
- Peanut-butter swirl: Drop ½ teaspoon of creamy peanut butter on each mound before you press—it gives a dreamy nutty note.
- Chocolate drizzle: Melt 2 ounces of dark chocolate and zigzag it over the chilled cookies for a touch of indulgence.
- Sprinkle blast: Mix in or sprinkle on mini rainbow jimmies for extra color (and a little extra crunch!).
- Froot Loops remix: Swap half the Fruity Pebbles for Froot Loops to up the fruity flavor complexity.
- Nutty crunch: Stir in 2 tablespoons of toasted chopped almonds or peanuts—just mind any allergy warnings.
- Marshmallow mushroom: For a festive twist, add one larger marshmallow in the center of each cookie before chilling.
Storage & Reheating Tips
- At room temperature: Store in an airtight container for up to 3 days—just make sure your kitchen isn’t a sauna.
- In the fridge: They’ll keep up to a week, though they might lose a little snap (the chew is still delish!).
- Freezer-friendly: Stack them with parchment between layers in a sealed bag or box. They last up to a month. When you’re ready, let them sit on the counter for 10 minutes or give ’em a 5-second zap in the microwave.
- Gift packing: Layer in a pretty tin with tissue paper for adorable, grab-and-go party favors.

Fruity Pebbles Cookies
Ingredients
- 4 cups Fruity Pebbles cereal Kellogg’s recommended for brightest color
- 1 cup crisp rice cereal optional, for extra crunch
- ¼ cup unsalted butter ½ stick; you can sub coconut oil for dairy-free
- 8 oz mini marshmallows about 4 cups; vegan marshmallows work too
- ½ teaspoon pure vanilla extract
- Pinch fine sea salt balances sweetness
- Nonstick spray or a sheet of parchment paper for easy shaping
Instructions
- Line a baking sheet with parchment or coat it lightly with nonstick spray—this speeds up cleanup.
- In a medium saucepan over low heat, stir the butter until it’s just melted (no browning). Keeping heat low prevents scorching.
- Toss in the mini marshmallows and stir constantly; remove from heat when only a few small marshmallow bits remain (they’ll finish melting off the heat).
- Stir in vanilla and a pinch of salt—this little extra makes all the difference.
- Pour both cereals into the pot and fold gently with a silicone spatula until every grain is coated in gooey marshmallow.
- Let the mixture cool for 1–2 minutes so it’s still pliable but not scorching. Use a 2-Tbsp cookie scoop or your hands (greased or wearing food-safe gloves) to form rounds, placing them on the sheet about 1 inch apart.
- Pop the tray into the fridge for 15–20 minutes. This firms the cookies and gives them that chewy-crunch balance we love.
- Once set, they’re ready! Transfer to a plate for immediate munching or follow the storage tips below.
