How to: Make Fruity Pebbles Rice Krispie Treats

Rice Krispies are extremely easy to make, and it’s no different for these fruity pebbles rice krispie treats!

The most important thing to remember when making anything with marshmallow fluff is to always, always, always spray all of your bowls and stirrers with enough cooking spray. I use avocado oil, but you can also use olive oil, butter spray, and any other more neutral cooking spray you have.

Start by melting the butter in a pot on the stove. Only medium low heat is needed to heat these ingredients well enough. 

Once the butter has melted, add in the marshmallow fluff and stir frequently – it can burn easily! Keep stirring and heating until the marshmallow is combined with the butter and is smooth.

In a large bowl, add your fruity pebbles. Pour the marshmallow and butter mixture over the cereal and use your heavily sprayed stirrer to mix. Keep stirring until it is fully incorporated and you have a nice, even mixture.

Whether using a heart mold for Valentine’s Day or another baking dish, make you sure you spray it generously. Pour in the marshmallow cereal mixture and let it sit for 1 hour to harden. Store in the fridge to preserve it longer. Enjoy!

  4. Definitely going to try this with my daughter! I have to be honest, I’ve always steered away from marshmallow fluff because it stuck to the bowl/mixer. Never thought to try cooking spray! This is a great and simple project it seems. Thanks!

    This is just the recipe I needed for this weekend, we have a children’s party to attend and have been asked to bring something tasty. I’m sure the kids are all going to go crazy over these!
