Why This Lucky Charms Recipe Works!
- They are no bake and only take about 15 minutes to make. It doesn’t get easier than this!
- With only 5 ingredients it’s easy to have the ingredients on hand to make whenever you need a quick treat.
- Bright, fun colors, plus delicious, so kids love them and so do adults!
Only 5 Ingredients Needed!
- Lucky Charms Cereal – They are so many fun twist on Lucky Charms cereal. We used the traditional type, but mix it up with different ones.
- Butter – Grab the salted butter for this recipe because it will help balance out the sweetness.
- Mini Marshmallows – Skip the big marshmallows and go for mini ones to help them melt evenly. Plus we add a few extra in after we mix the cereal to add to the ultimate gooey marshmallow factor.
- Vanilla – Optional, but we love the added boost of flavor it adds in this recipe.
- Pastel Sprinkles – Also, an optional ingredients, but the sprinkles on top make it all the more fun!
How to Make Lucky Charms Treats
- Prep – Spray a 9’’ x 13’’ pan with non-stick spray or line with heavy duty aluminum foil greased with non-stick spray. If using foil let it drape over the sides of the pan for easy removal of bars.
- Reserve Marshmallows – In a large bowl measure out Lucky Charms. Take out 1/4 c. of the marshmallows from the cereal and set aside. Remove two cups of mini marshmallows and set aside.
- Melt – Place the butter slabs and remaining mini marshmallows in a large microwave safe container. Microwave for 2 minutes. Remove and stir until butter and marshmallows are melted and combined. Add vanilla and stir until combined.
- Combine – Quickly mix cereal into the melted marshmallows and stir until it is combined. Add reserved mini marshmallows and stir until they are softened and partially melted. You do not want them to completely melt as the provides those delicious pockets of marshmallow goo.
- Finish – Press mixture into prepared pan. You can butter your fingers to help press them into the pan with less mixture sticking with to them or use the butter wrapper to push the mixture into the pan. Damp fingers also work to help press the mixture into the pan without getting it stuck to your fingers.
- Top – Take the 1/4 c. reserved Lucky Charms marshmallows and press into the top of the bars. Then sprinkle with sprinkles if desired.
- Cool – Let cool at room temperature for at least a hour.
Pro Tips!
- Line Pan – To make it easy to remove the bars, line your baking dish with enough tin foil so you have extra that hang over the edges of the pans. That way, you can grab it and lift the bars out in one whole piece before you slice them. If you skip lining it make sure it’s butter or sprayed with non-stick spray.
- Use Fresh Marshmallows – Marshmallows that have been around too long harden and if you if use them to make these treats your bars won’t be chewy they’ll be rock hard!
- Use PURE VANILLA EXTRACT – Pure vanilla extract is made with real vanilla, so don’t substitute regular vanilla extract otherwise you won’t get that wonderful natural vanilla flavor.
- Do not press firmly into pan – When you press the bar mixture into the pan don’t press too hard otherwise your bars will be too dense and too chewy. Lightly press it in so that there is still plenty of air in the bars.
- Use wet hands or buttered hands to press into pan – If you’ve ever tried to press sticky marshmallows and cereal with your hands you know you end up with more stuck to your hands than in the pan! To make it easier, butter or wet your hands with water when you handle the mixture so it goes in the pan and doesn’t stick to you.

These look great! How many drops of green food colouring did you add? 🙂
Julie Evink says
Ah I can’t remember! Just keep adding till you like the green color. It’s different if you use regular food dye v.s. a gel dye too. I used the gel dye so I wouldn’t have used as much!
