Ingredients

You only need 4 simple ingredients to make Froot Loop cereal bars. They should be easy to find in your grocery store.

  • Froot Loops Cereal — or a generic brand
  • Marshmallows — 10 ounces, any size marshmallows
  • Butter — unsalted butter or salted butter will work
  • Vanilla extract — adds flavor

You will also need a 9 x 13-inch baking dish or casserole dish, a large microwaveable bowl or large pot, and a rubber spatula. Non stick cooking spray and extra butter are helpful for greasing the baking pan.

How to Make Froot Loops Bars

I always melt the marshmallows in a microwave-safe bowl, but you can do this on the stove top if you like.

Melt the marshmallows and butter starting at 30 seconds. Then, stir with the spatula, and melt in 30-second intervals until marshmallows are melted.

In my microwave, it takes about 1 minute 30 seconds.

Stir in the vanilla extract. Then, add the Froot Loops, and stir the cereal mixture until well blended.

Your arm will get a good workout!

Spray the baking dish with non-stick spray. Then, scoop the gooey marshmallow mixture into the prepared pan.

Let these colorful cereal treats cool for about 30 minutes to 1 hour. Then, slice them into bars.

Tip — spray the spatula with non-stick cooking spray so that it doesn’t stick to the marshmallow-coated cereal.

How to Store

Store these fun treats in an airtight container at room temperature. They stay fresh for about 1 week, if they last that long! You can freeze marshmallow treats for up to 3 months.

If your house is very warm, you can refrigerate them and allow them to come to room temperature before eating.

Expert Tips

For 10 ounces of marshmallows, you can use 6 cups mini marshmallows, about 40 large marshmallows or about 15 jumbo marshmallows. If you have a kitchen scale, you can weigh the marshmallows before using them to be exact.

If you have 12 ounces of marshmallows, use 7 cups cereal.

Spray or butter the pan to make the bars easier to remove. You can also use parchment paper or wax paper to line the pan.

Spray the spatula with non-stick spray so that the cereal doesn’t stick.

Recipe Variations

Garnish these tasty cereal bars with your favorite sprinkles or candy sprinkles for an extra special treat.

You can leave out the vanilla extract if you like.
