Ingredients to Make Fruity Pebble Rice Krispie Treats
Here is a visual overview of the ingredients in the recipe. Scroll down to the recipe at the bottom for quantities.

- Fruity Pebbles Cereal: There are also off-brand versions of fruity pebbles which will work just as well in your dessert.
- Unsalted butter: I prefer to use unsalted butter so that I can adjust the amount of salt in the recipe according to my own tastes. If you only have salted butter, you may not need the extra salt called for in the recipe.
- Marshmallows: You can use mini marshmallows or jumbo marshmallows, as long as there is 10 oz of them. If using large marshmallows, you may want to cut them down to a smaller size to make the melting process a little smoother. Feel free to add some extra mini marshmallows into the blend later (not melted) so that you can have an unmelted marshmallow in your bites!
- Vanilla extract: If you left out the vanilla extract, your treats would still hold together nicely. But I like the fact that the vanilla adds a warm tone to the sweetness of this dish.
- Sweetened condensed milk: Sweetened condensed milk is not a typical ingredient in Rice Krispie Treats, but I love the texture that it adds. It takes your bars from basic to bakery-quality, making them extra chewy, sweet and delicious!
Recipe Variations

Rice krispie treats are so versatile so don’t limit yourself. You could make this same recipe with Cocoa Pebbles for a chocolate twist. You could also throw in some white chocolate chips for added sweetness!
Tools
- Large pot: A heavy bottomed pot will keep the marshmallows from burning faster
- Mixing Bowl: If you really want to save some dishes, you can also mix the treats right in the pot (as long as it is removed from the heat first!)
- 9×9 Baking Dish: You could use a 9×13 baking dish but your bars will turn out thinner.
How to make this recipe

Step One: In a large pot add the unsalted butter and marshmallows and stir until melted.

Step Two: Add in the vanilla extract and sweetened condensed milk.

Step Three: Pour the marshmallow mixture over your fruity pebbles cereal.

Step Four: Stir until evenly distributed.

Step Five: Press the mixture into a prepared baking dish to cool.
Expert Tips
- Your mixture will be sticky when you transfer it to your pan. Spraying the tips of your fingers with a bit of non-stick spray can make it easier to pat the mixture into your pan.
- Be gentle when pressing your mixture into your pan! Too much pressure will make for dense bars, rather than light and crispy!
- Be sure and cook your marshmallow mixture over low heat. You do not want to deal with burnt marshmallows in your pan!
