Recipe Ingredients
- Rice Krispies: The base of these cereal bars providing the perfect crisp texture.
- Lucky Charms: We will use the cereal AND extra marshmallows. They sell bags of just the Lucky Charms Marshmallows if you don't want to pick through the box (arguably the best part, so the extras won't go to waste).
- Marshmallows: I prefer mini marshmallows because they soften and melt better.
See the recipe card below for a full list of ingredients and measurements.
Substitutions and Variations
A few ways you can switch up these treats:
- Cereal: I used both Lucky Charms and Rice Krispies because I like multiple textures. Feel free to use only Lucky Charms or try replacing the Rice Krispies with another cereal like Cheerios, Captain Crunch, or Chex.
- Marshmallows: Try rainbow marshmallows for an extra colorful treat.
- Butter: Salted, unsalted, or vegan butter all work. You can also sub coconut oil.
- Extras: Add vanilla to the melted butter for extra flavor! Also try dipping the bottom of the cooled bars in melted white chocolate to make them more like the store bought Lucky Charm Bars.
How to Make This Recipe
1. Heat a large pot on medium-low heat. Once warm, add the butter and let it melt. Stir continuously so it does not burn.
2. Once butter has melted, add the marshmallows.
3. Continue stirring until the marshmallows are 75% melted. Turn off the stove and remove the pan from heat.
4. Pour in Rice Krispies 3 cups Lucky Charms, the Lucky Charms cereal from the separated portion, and salt.
5. Stir cereal and marshmallow mixture together. Do not over stir or marshmallows will become overly stiff.
6. Spray a 9x13 pan generously with cooking spray and pour the cereal mixture into the pan. Spread evenly. Then press the Lucky Charm marshmallows on top. Let the treats chill for 30 minutes. Then, cut and enjoy!
Expert Tips
Do not press the cereal mixture hard into the pan. This'll create much too dense of a texture. You want the marshmallow and cereal mixture to create a web so they're not too hard when you eat them.
Don’t let the butter/marshmallow mixture harden. You’ll want to work quickly so the melted marshmallows can coat the cereal. If you wait too long the cereal and marshmallows will not combine.
To make these extra festive for St. Patty’s Day, add clover sprinkles to the top, too!
Recipe FAQs
I prefer to store Rice Krispie Treats in the refrigerator, but the counter is also fine. They keep for up to 3 days. Just note that the longer they sit, the less crisp they will hold. Make the day of serving for optimal freshness. These freeze well too!
These are Rice Krispies Treats with Lucky Charms cereal instead of just the Rice Krispies alone. We all love the tiny colored marshmallows in Lucky Charms, so we’re adding those on top, too.
Spraying a pizza cutter or large knife works great for cutting Rice Krispie treats. Be sure the bars are completely cooled and set before attempting to cut them.
This recipe has not been tested with off brand Lucky Charms or Rice Krispies, so I cannot tell you if they'll turn out. Just know that might change the texture or flavor!

I made these for my son’s St. Paddy’s party at school. I love that they are allergen friendly for those who are nut free. They are fast, easy, and delicious! We elected to drizzle with white chocolate (using green food coloring) to add a festive color!
