Fruit Loop Cereal Bars are seriously one of the most delicious things you will ever eat in your life! If they weren’t already a breakfast cereal I would assume they were made exclusively as a dessert snack.

Fruit Loops Cereal Bars
If you’re getting tired of the original Rice Krispie Treats, you may want to try something a little bit different. Queue Fruit Loops Cereal Bars.
They add a delicious fruit flavor to an already great classic. In fact, Fruit Loops can make any number of interesting desserts like these Fruit Loop Sugar Cookies.
These cereal bars are great for a last minuter snack for an unexpected party or if you just want to have a lazy weekend. They take the same amount of time to make as original and just as tasty.
How to Make Froot Loops Cereal Bars
Overall, froot loops cereal bars are pretty easy to make. In fact much like other cereal bar treats (for example: Lucky Charms Bars, Frosted Flake Cereal Bars and Fruity Pebble Rice Krispie Treats), you simply use the original rice krispie treat recipe and substitute in Froot Loops Cereal.
Before you get things going, you’ll need to make sure you have the right ingredients and supplies to make these.
Ingredients you’ll need are:
- Froot Loops Cereal
- Marshmallows (we like to use Kraft brand)
- Salted Butter
- (optional) butter spray
Supplies you’ll need are:
- 9×13 pan
- Microwave safe bowl or pot
- Spatula
Make sure to pre-grease both your 9×13 pan as well as your spatula before you get started. This marshmallow and Froot Loop Cereal mixture tends to be EXTRA sticky. The cereal pieces are a lot larger than rice krispies or fruity pebbles and so the marshmallow tends to be in bigger sections and chunks as it coats the cereal.
To pre-grease your supplies, you can either use non-stick cooking spray – that is our preference, although it does have a different flavor than regular butter. Or, you can simply use a pad of butter and rub it around your pan and spatula.

Step One
The first step in the process is to melt your butter. Take 4 tablespoons of butter and place them in a large stock pot. Place your pot on your stove top and set the heat for medium.
You can use your spatula to move the butter around the pan. I honestly can’t tell you if it makes it melt faster but it makes me feel like it does.
Once your butter has melted, grab your bag of marshmallows and dump the whole thing into the pot. Use a spatula to turn the marshmallows over to get coated in the butter. Continue stirring until the marshmallows have completely melted and you have a nice gooey butter/marshmallow mix.
If you want to speed up the process a little you can also melt you butter and marshmallows at the same time in the microwave. To do this, start with 60 seconds.
Once you’ve heated for a minute, stir well. Then pop back in the microwave at 30 – 60 second increments until it is all thoroughly melted together.
Tip: Don’t overheat the marshmallows as they will stiffen and become hard to mix later. They will puff up when heating in the microwave, which is normal. Just stir and push them down and keep heating.

Step Two
Remove your marshmallows from the stove top and get your Fruit Loops ready. Pour 6 cups of cereal into the marshmallows. You can stir while pouring to get a thorough mix. It can help to coat your spatula in butter first to keep everything from sticking too much.
Continue stirring until your Fruit Loops and marshmallows are completely mixed together. The key here is to have your spatula VERY well greased and also to try and mix things together fairly quickly so that the marshmallows do not cool and stiffen up.
Step Three
Once the marshmallows and Froot Loops cereal are mixed, they become much stickier and harder to work with. If you didn’t pre-grease your 9×13 brownie pan then you’ll want to do it at this time.
Using your spatula (sometimes we use an additional spatula or large spoon), start scooping your cereal mix into the pre-greased pan. Once everything is moved into the pan, pat it down with your spatula until you have an even flat surface and the entire pan is full.
Tip: Make sure not to push things too hard, or you will crush the cereal pieces and make the treats too compact.
Step Four
Now, leave your treats to sit for a while. You can also stick them in the fridge for a few minutes to speed up the process (or the freezer if you’re impatient like me). If you don’t allow them time to cool, they are difficult to cut and make a big mess.
Once your treats have cooled down, take a sharp knife and cute into even squares. You should get about 16 squares from a 9×13 brownie pan.
Serve and enjoy!
Want to save more for later?
If you don’t gobble these all up in one day, you’ll want to store them for later. Simply place them into an air tight container. They should stay good for about 5 days.
Or, you can double the recipe and make two full batches. Then you can consider freezing Rice Krispie Treats for later. Simply wrap them, pop them in a freezer bag and then put them in the freezer.
