Ingredients
- Fruity Pebbles cereal: The star of the show! Both name-brand and store-brand versions (like Aldi) work perfectly.
- Marshmallows: Mini or regular — whatever’s in your pantry.
- Butter: Unsalted is best, but salted butter works fine in a pinch.
- Vanilla extract: Adds that hint of sweetness and depth to balance the fruity cereal.
Tip: Don’t use wax paper when lining your pan — it will melt into the mixture (trust me, I’ve been there!). Use parchment or foil instead.
How to make fruity pebbles treats
Spray an 11x7-inch or 9x13-inch baking dish with nonstick cooking spray and line it with parchment paper for easy removal.
Melt Butter. In a large saucepan, melt the butter over medium-low heat. Add the marshmallows and stir until completely melted and smooth. Stir in vanilla extract.
Add the marshmallows and stir until completely melted and smooth. Stir in vanilla extract.
Add the marshmallows and stir until completely melted and smooth. Stir in vanilla extract.
Remove the pan from heat and quickly stir in the Fruity Pebbles cereal until fully coated in the marshmallow mixture.
Spread the mixture evenly into your prepared pan using a spatula sprayed with nonstick spray (or buttered lightly). Press it in gently — too firmly and your bars can turn hard.
Allow the treats to cool before slicing into bars with a sharp knife.
If you're in a hurry to taste these, you can pop them in the fridge for a few hours and they'll set up more quickly!

Top Tip
For extra fruity flavor, sprinkle a few extra Fruity Pebbles on top before pressing the mixture into the pan. It adds color and crunch!
Microwave Method
You can make these right in the microwave!
In a large microwave-safe bowl, melt the butter. Add marshmallows and heat in 30-second intervals, stirring between each round until smooth. Stir in vanilla and cereal, then press into the pan as directed.
Variations
Switch up the cereal: Try Trix, Fruit Loops, or Cocoa Pebbles for a fun flavor twist.
Extra marshmallowy: Press a few mini marshmallows on top before cooling for extra gooey bites.
Add a drizzle: Melt white chocolate or candy melts and drizzle over the top once cooled.
Storage & Freezing Tips
- Store: Keep Fruity Pebbles Treats in an airtight container at room temperature for up to 3 days.
- Freeze: Wrap each square in plastic wrap, place in a freezer bag, and freeze for up to 6 weeks. Thaw at room temp before serving.
Helpful Tips for Perfect Fruity Pebbles Treats
💡 Don’t overheat the marshmallows — this makes the bars tough. Melt just until smooth.
💡 Use fresh marshmallows for the best melt and chewiness.
💡 Grease your spatula or hands before pressing the mixture into the pan to keep things from sticking.
