We’re using the actual marshmallows from Lucky Charms cereal for double the enchantment (and none of those boring plain bits!).
Don’t worry if you’ve never made rice crispy treats before—this foolproof recipe walks you through every step with pro tips for cutting clean squares, preventing sticky messes, and customizing your treats for different occasions. Let’s create marshmallow magic together!
Why These Are the Best Lucky Charms Treats You’ll Make
Most recipes use plain marshmallows mixed with Lucky Charms cereal, but that dilutes the vibrant marshmallow magic. Our method uses only the marshmallow pieces from Lucky Charms boxes combined with standard marshmallows—ensuring maximum color and flavor concentration in every bite. This creates:
– Brighter colors without dull beige cereal bits
– Stronger marshmallow flavor from double sources
– Textural perfection (chewy + crispy balance)
– Visual wow factor with marshmallows peeking through
Gathering Your Magical Ingredients
Here’s what you’ll need for one 9×13 pan of treats:
Core Components:
– 3 tablespoons salted butter (creates rich flavor; unsalted works too)
– 10 oz bag regular marshmallows (about 40 large marshmallows)
– 4 cups crispy rice cereal (like Rice Krispies)
– 2 cups Lucky Charms marshmallows ONLY (sorted from 2 family-size boxes)
Flavor Boosters (Optional):
– 1 teaspoon vanilla extract (enhances sweetness)
– 1/4 teaspoon fine sea salt (balances sweetness)
Pro Tip: Sorting marshmallows is easier than you think! Pour cereal into a large bowl, pick out marshmallows with clean hands or a slotted spoon, and save the cereal bits for parfaits or snack mixes.
Step-by-Step Magical Treat Creation
Follow these steps for perfect treats every time:
1. Preparing Your Pan (The Secret to Clean Edges)
Line your 9×13 baking pan with parchment paper, letting excess hang over two sides. Lightly coat with butter or non-stick spray—this prevents sticking and creates easy lifting later.
Alternative Pans: Don’t have 9×13? Use:
– Two 8×8 pans (for thicker bars)
– Muffin tin (portion-controlled “cupcakes”)
– Silicone molds (fun shapes like stars or hearts)
2. Melting the Marshmallow Base
– Melt butter over low heat in a large pot (prevents scorching)
– Add regular marshmallows and stir constantly until fully melted (5-7 mins)
– Remove from heat immediately when smooth
Key Mistake Alert: High heat creates tough, rubbery textures. Keep that burner low!
3. Combining Cereal & Marshmallows
Working quickly:
– Stir in vanilla/salt if using
– Fold in crispy rice cereal until fully coated
– Gently mix in Lucky Charms marshmallows (reserve 1/4 cup for topping)
– Transfer to prepared pan
4. Pressing for Perfect Texture
– Lightly butter your hands or a spatula
– Press mixture gently into pan—don’t compact it!
– Sprinkle reserved marshmallows on top
– Let cool for 2 hours before cutting
Texture Trick: Place wax paper over treats and press evenly with another pan for flawlessly flat surfaces.
Creative Twists & Dietary Modifications
Festive Variations
– Birthday Cake: Mix in rainbow sprinkles + substitute golden Oreo crumbs for 1 cup cereal
– Chocolate Lovers: Drizzle melted chocolate over cooled treats
– Salted Caramel: Swirl 1/4 cup caramel sauce into marshmallow mixture
Allergy-Friendly Adjustments
– Gluten-Free: Use gluten-free crispy rice cereal and confirm Lucky Charms marshmallows are GF (they currently are!)
– Dairy-Free: Substitute vegan butter sticks (like Miyoko’s or Earth Balance)
– Vegan: Use Dandies vegan marshmallows + vegan butter
Pro Tips for Cutting & Serving
– Warm Knife Method: Run knife under hot water, dry, then cut—wipes clean after each slice
– Shape Ideas: Use cookie cutters for shamrocks (St. Patrick’s Day) or stars
– Portion Control: Cut into 1-inch squares for party toothpick picks
Presentation Hack: Stack treats in a clear jar wrapped with green ribbon for leprechaun-themed gifts!
Storage & Freshness Guide
– Room Temperature: Store in airtight container for up to 5 days (place wax paper between layers)
– Refrigerator: Up to 2 weeks—may harden slightly; let sit at room temperature 30 mins before eating
– Freezer: Wrap tightly in plastic + foil for 3 months; thaw at room temp
Reviving Stale Treats: Microwave individual squares for 5-8 seconds to restore gooeyness.
6 Mistakes That Ruin Lucky Charms Treats (and How to Avoid Them)
1. Crumbly Bars: Caused by undermeasuring marshmallows. Always weigh marshmallows for accuracy.
2. Hard Texture: Overheating marshmallows kills their elasticity. Low and slow melting is crucial.
3. Soggy Treats: Humidity softens cereal. Make on dry days or add 1 extra cup cereal in humid climates.
4. Burnt Butter: Melt butter over lowest heat setting.
5. Discolored Marshmallows: High heat melts colored coatings. Never add Lucky Charms marshmallows to hot mixture.
6. Uneven Cutting: Cutting before fully cooled causes caves and crumbles. Be patient!
Your Lucky Charms Treats Questions Answered
Can I use only Lucky Charms marshmallows without regular marshmallows?
No—the cereal marshmallows alone won’t provide enough sticky binder. You need standard marshmallows’ gelatin content for proper adhesion.
Can I make these ahead for a party?
Yes! Prepare up to 3 days in advance. Store layered with wax paper in airtight containers at room temperature.
Help! My marshmallows melted completely—is it ruined?
Charm shapes dissolve if overheated, but your treats will still taste delicious—just less colorful. Reduce heat next time.
What can I do with leftover cereal pieces?
Mix into yogurt, blend into milkshakes, or bake into cookies. We love making “Lucky Popcorn” by drizzling with white chocolate and sprinkling cereal bits.
Can I freeze these if I double the batch?
Absolutely! Freeze uncut slabs wrapped in plastic + foil. Thaw uncovered at room temp before slicing.
Why isn’t my mixture sticking together?
Likely undermeasured marshmallows. To salvage, return mixture to pot, melt 1 extra cup marshmallows, and recombine.
