How to Make Fruity Pebbles Treats
Here’s how to make rice crispy treats with Fruity Pebbles. They’re so easy!
- Step 1: Prepare the Pan. Spray a 9x13-inch baking pan with cooking spray. This makes it easy to get them out of the pan when you go to serve them.
- Step 2: Melt the Butter and Marshmallows. In a large microwave-safe bowl, melt the butter first, then add mini marshmallows and heat in 30-second intervals, stirring between each, until completely smooth and melted.
- Step 3: Add the Vanilla and Cereal. Stir in the vanilla extract, then gradually fold in the Fruity Pebbles, gently mixing until all cereal pieces are evenly coated with the marshmallow mixture.
- Step 4: Press and Set. Transfer the mixture to your prepared pan, lightly spray your hands with cooking spray to prevent sticking, then gently press the mixture into an even layer without compacting it too firmly. Let them set for 30 minutes before cutting into squares.
Hint: Press Gently
You don’t need to push too hard when pressing these Fruity Pebbles marshmallow treats into the pan. Otherwise, they can get too dense and chewy. Just press lightly to give the best texture.

Expert Tips
- Folding in the Cereal: You'll want to work quickly to combine the cereal with the melted marshmallows. It begins to set quickly so you don't want to delay.
- For the Best Texture: Press gently when putting the mixture into the pan. Otherwise it can crush the cereal and make the treats more dense and chewy than you want them.
- Clean Cut Squares: Let the treats set for 30 minutes then use a knife lightly coated with cooking spray to slice them.
Storing Tips
- Storing: Leftover Fruity Pebbles marshmallow treats keep in an airtight container for up to 3-4 days. Place parchment paper between layers to prevent the bars from sticking to each other. I don't recommend freezing.
- Make Ahead: These treats are perfect for making 1-2 days ahead of parties or events. Allow them to set completely before cutting and storing in an airtight container.
Serving Suggestions
These are the perfect late-night snack, special lunch treat, or on-the-go dessert! Here are some ideas for serving after you make this Fruity Pebbles treats recipe.
- Have a dessert potluck and bring extra treats to go with the rice crispy treats! For a fruity theme, make orange creamsicle cookies, strawberry fluff salad, and fruit pizza.
- Serve with an ice-cold glass of milk or a scoop of homemade vanilla ice cream.
- Have an easy picnic and serve them with grilled chicken wraps and Hawaiian macaroni salad.

Recipe FAQs
Yes, you can heat up rice crispy treats in the microwave for 10-15 seconds. Keep in mind that this will make the marshmallows sticky.
For best results, it is recommended to store rice crispy treats at room temperature in an airtight container. Refrigerating them will cause the marshmallows to become hard and dry.
