Lucky Leprechaun Rice Krispie Treats are a fun and festive twist on the classic marshmallow and crispy rice cereal snack. These treats are colorful, crunchy, and chewy all at once, usually featuring a splash of green or golden hues that remind you of St. Patrick’s Day magic. They’re simple to make but can really brighten up any party or special occasion.
I love making these treats with kids because they get so excited about shaping them into fun little pots of gold or adding sprinkles and candy “coins.” It’s one of those easy recipes where you don’t have to worry about getting everything perfect — the messier and more colorful, the better! I usually add a little extra butter to make them extra soft, and sometimes I sneak in some crushed cereal for a different texture that everyone enjoys.
When it comes to serving, I like to pop these treats into a cute container or wrap them up in little cellophane bags tied with a green ribbon. They’re great for packing in lunchboxes or handing out at classroom parties. Honestly, they’re a simple treat that brings smiles every time, and I often find myself nibbling on them long after the celebration’s over!
Key Ingredients & Substitutions
Crispy Rice Cereal: This is the base that gives crunch and structure. I like Rice Krispies, but puffed rice or homemade crispy rice will also work. For more color, adding Lucky Charms cereal brings in fun marshmallow bits perfect for the theme.
Marshmallows: They melt into the butter to bind everything. Mini marshmallows melt faster and more evenly, but regular marshmallows are fine too. For a dairy-free option, use vegan marshmallows, but results might be a little different in texture.
Butter: Adds flavor and richness while helping melt the marshmallows. Unsalted butter gives the best control over saltiness, but margarine or coconut oil can work if needed—just note it might change taste slightly.
Green Food Coloring: This gives a festive touch but is optional. You can also use natural green colors like spinach powder, though it won’t be as vivid. If you prefer no color, the treats still taste great!
Decorations: Candy eyes and fondant hats bring the leprechaun characters alive. If you want ease, edible markers or colored icing can be fun alternatives. Mini marshmallows add texture and look like fluffy clouds, making the treats extra cute.
How Can You Make Sure the Rice Krispie Treats Stick Together Perfectly?
The key to the best texture is melting the marshmallows gently and mixing everything quickly before it sets. Here’s how I do it:
- Use low heat when melting butter and marshmallows to avoid burning.
- Keep stirring until completely smooth and melted—no big marshmallow chunks.
- Work fast when adding the cereal and pressing the mixture into the pan. The marshmallow will start to harden quickly.
- Use a buttered spatula or wax paper to press the mixture evenly—it stops sticking and keeps the treats nice and flat.
- Let the treats cool completely before cutting. This helps them hold their shape and prevents crumbling.
These tricks make your Lucky Leprechaun Rice Krispie Treats soft but firm, with every bite perfectly chewy and crunchy!
Equipment You’ll Need
- Large mixing bowl – I use it to toss the cereal and marshmallow mixture easily and keep everything together.
- Large saucepan – for melting butter and marshmallows smoothly on the stove.
- 9×13 inch baking pan – perfect for spreading and shaping the treats; line it with parchment paper for easy removal.
- Spatula or buttered spatula – helps press the mixture evenly into the pan without sticking.
- Knife – to cut the treats into neat squares once they’re set.
- Decorating tools (optional) – like piping bags, small spatulas, or toothpicks for adding hats and eyes.
Flavor Variations & Add-Ins
- Swap marshmallows for chocolate chips or add a handful for extra sweetness and gooeyness.
- Mix in crushed cookies or pretzels for added crunch and flavor contrast.
- Use different colored marshmallows or food coloring for more festive or themed treats.
- Add a splash of vanilla or peppermint extract to the marshmallow mixture for a fun flavor twist.

How Much Time Will You Need?
This recipe takes about 10 minutes to prepare and mix, plus about 10 minutes to cool before cutting and decorating. The whole process can be completed in about 25–30 minutes, making it a quick and easy treat to whip up for any celebration.
Step-by-Step Instructions:
1. Prepare Your Pan:
Lightly grease a 9×13 inch baking pan with butter or non-stick spray. This will help you remove the treats easily once they’re set.
2. Melt Butter and Marshmallows:
In a large pot, melt 3 tablespoons of unsalted butter over low heat. Add your marshmallows and stir continuously until they’re completely melted and smooth.
3. Add Color and Cereal:
Remove the pot from heat and add a few drops of green food coloring. Stir well until evenly green. Quickly add the crispy rice cereal and Lucky Charms cereal, stirring until all the pieces are coated evenly with the marshmallow mixture.
4. Press and Cool:
Pour the mixture into your prepared pan. Use a buttered spatula or wax paper to press it evenly and firmly. Let it cool for about 10 minutes until firm but still soft enough to cut.
5. Cut and Decorate:
Use a sharp knife to cut the treats into squares. Decorate each square with two candy eyes on top and add mini marshmallows to create a puffed effect if you like. For festive flair, place little leprechaun hats made from fondant or pipe hat shapes using colored icing above the eyes. Let the decorations set before serving.
Can I Use Frozen Marshmallows for This Recipe?
It’s best to use fresh marshmallows for melting since frozen ones can become sticky and clump. If you only have frozen marshmallows, let them thaw completely at room temperature before melting.
How Can I Store These Rice Krispie Treats?
Store leftovers in an airtight container at room temperature for up to 3 days. Avoid refrigerating as it can make the treats hard. For longer storage, wrap tightly and freeze for up to 2 weeks.
Can I Substitute the Lucky Charms Cereal?
Absolutely! Any colorful marshmallow cereal works well to add fun shapes and colors. If you prefer, you can leave it out entirely and just use crispy rice cereal for a classic flavor.
What’s the Best Way to Cut the Treats Without Crumbling?
Use a sharp knife and wipe it clean between cuts. Press the knife down firmly in a straight motion rather than sawing back and forth to keep the edges neat and prevent crumbling.
