A childhood throwback recipe, Fruity Pebbles Marshmallow Treats are super easy to make and great for picnics and potlucks!
This recipe is not any different than it was thirty years ago. It’s not technical and not revamped. It’s just a great throwback recipe that was great then and is just as great now. A little reminder of simpler times!
What You’ll Need to make Fruity Pebbles Marshmallow Treats
- Butter – We use regular salted butter, but unsalted butter may also be used.
- Mini Marshmallows – 10 ounce bag, about 4 cups. Regular marshmallows may be used but they will take longer to melt!
- Vanilla Extract – Adds flavor and enhances other flavors.
- Fruity Pebbles Breakfast Cereal – While other types of cereal can be used (the sky is the limit!) we love these when made with Fruity Pebbles.
How to Make Fruity Pebbles Marshmallow Treats
Four ingredients and no baking. These are the perfect addition to any picnic or potluck. Tasty, transportable and full of childhood memories!
Generously butter an 8×8 or 9×9 inch square pan and set aside.
Note: The marshmallow mixture is always pretty sticky – grease the pan more than you think you should!
Melt 1/4 cup of butter in large saucepan over medium-low heat. Add the marshmallows.
Note: 4 cups of mini marshmallows will melt faster than a bag of the large ones!
Stir until the marshmallows are almost completely melted then add in the vanilla extract.
Continue to stir until the mixture is completely smooth and then remove from the heat.
Add Fruity Pebbles cereal.
Stir with a spatula or wooden spoon until the cereal is well coated.
Transfer the mixture to the prepared pan.
Spread the mixture evenly in the pan with buttered wax paper or a spatula.
Cut into squares when cool. These are best if made and served on the same day. Enjoy!
