Ingredients You'll Need
- 6 Tablespoons salted butter (unsalted works too)
- 1 bag (16 oz) mini marshmallows, divided (about 9 cups)
- 1 teaspoon vanilla extract
- 7 cups Lucky Charms cereal
Pro Tip: Want a richer flavor? Use homemade vanilla extract for an extra boost of deliciousness!
Step-by-Step Instructions
1. Prepare the Pan
Line a 9-inch square baking dish with parchment paper. This makes it easier to lift out and cut the bars later.
2. Melt the Butter and Marshmallows
In a large saucepan, melt butter over medium heat. Add all but one cup of the mini marshmallows and reduce heat to low. Stir continuously until fully melted.
3. Mix Everything Together
Remove from heat and stir in vanilla extract. Quickly add Lucky Charms cereal and the remaining cup of mini marshmallows. Gently fold until fully combined.
4. Press and Set
Transfer the mixture into the prepared baking dish. Lightly press the mixture using wet fingertips to prevent sticking. Let sit for about 1 hour to firm up.
5. Slice and Enjoy!
Once set, lift the bars from the pan and cut them into squares. Serve immediately or store for later!
Pro Tip: If you prefer thinner bars, use a 13x9-inch pan instead!

Tips & Tricks for the Best Lucky Charms Treats
- Use fresh ingredients – Stale cereal or marshmallows can make these treats taste off.
- Don’t press too hard – Lightly press the mixture to keep your treats soft.
- Prevent sticking – If the mixture sticks to your hands, dip your fingers in water or butter.
- Make it extra gooey – Add an extra half cup of marshmallows for a softer texture.
- Customize your mix – Try adding chocolate chips, sprinkles, or crushed Oreos for variety!
FAQs for Lucky Charms Treats Recipe
Yes! Use about 65 regular marshmallows to equal 9 cups of mini marshmallows. Just be sure to melt them slowly for the best consistency.
Melt the marshmallows over low heat and avoid overcooking them. Also, press the mixture lightly into the pan—pressing too hard makes the bars dense.
Use parchment paper with a little overhang for easy lifting. You can also lightly grease the pan with butter or cooking spray.
Yes! Swap out the butter for a dairy-free alternative like coconut oil or plant-based butter. Also, check that your marshmallows are gelatin-free, as some brands use animal-derived ingredients.
Absolutely! Add mix-ins like white chocolate chips, rainbow sprinkles, or crushed cookies before pressing into the pan. Keep in mind that chocolate chips may melt slightly from the warm marshmallows.
Store them in an airtight container at room temperature for up to 3 days. Avoid refrigerating, as they can become too hard. For longer storage, freeze for up to 6 weeks.
