Ingredients You’ll Need

Tip: You’ll find the full list of ingredients and measurements in the recipe card below.

Main Bars

• 2 tablespoons butter
• 5 cups (9 oz) mini marshmallows
• 6 cups (6.5 oz) Fruit Loops

Glaze

• 1 cup powdered sugar
• 2 tablespoons milk
• 2 tablespoons colored coarse sugar or sprinkles

Let’s Get Started

Prepare the Pan

Lightly spray a 9×9 inch square pan with non-stick cooking spray. This prevents sticking and makes removal easier. Set the pan aside.

Melt the Butter and Marshmallows

Place a large saucepan on medium-high heat. Add the butter and allow it to melt fully.
Once melted, add the mini marshmallows. Stir continuously until the marshmallows are fully melted and smooth.

Stir in the Fruit Loops

Add the Fruit Loops directly into the melted marshmallow mixture. Work quickly and fold until every piece of cereal is coated.

Transfer to the Pan

Pour the mixture into the prepared pan.
Use lightly greased hands or a silicone spatula to press the mixture evenly into the pan. Avoid pressing too hard—keeping it light helps maintain a soft, chewy texture.

Let the bars sit for 1–2 hours at room temperature to set.

Make the Glaze

In a small bowl, whisk together powdered sugar and milk until smooth. The glaze should be thick but drizzleable.

Decorate

Drizzle the glaze over the set cereal bars using a spoon. Sprinkle coarse colored sugar or rainbow sprinkles over the top before the glaze sets.

Slice and Serve

Once everything is set, slice into squares and enjoy!
