Ingredients

• 3 tablespoons unsalted butter
• 1 bag (10 oz) mini marshmallows
• 6 cups Trix cereal

Other items needed

• non-stick cooking spray
• large bowl
• spatula
• baking dish

Instructions

Spray baking dish with non-stick cooking spray; set aside. Put cereal in a large bowl, big enough to add melted marshmallow to with room for stirring; set aside.

Melt butter in a pot over medium heat. Once melted, add marshmallows to pot and stir until completely melted.

Once melted, remove from heat and pour over Trix cereal. Stir with spatula until completely coated and pour evenly into the prepared baking dish.

Allow marshmallow to cool and set. Cut into 16 squares. Store in an airtight container.

I don’t think there is a way you can mess up this super easy recipe. With only 3 required ingredients and basic tools you probably already have at home, this Rainbow Marshmallow Treats recipe is as easy as it gets.

I’m sure you can notice by the photos that I like for these treats to be very marshmallow-y. If you want, you could reduce the amount of marshmallows and butter. But, I like the ooey-gooey of the marshmallow so I go all in – an entire bag.

If you think it might be too much marshmallow for you, reduce the butter down by 1 tablespoon and only use 2/3 of the bag.
