St Patrick’s Day is an under-celebrated holiday if you don’t have children, but it doesn’t have to be! Whether or not you have kids, you can enjoy St Patrick’s Day. And the easiest way to enjoy a holiday? Dessert 😉 

I have some delicious St Patrick’s Day desserts, including Lucky Charms Cookies or these Easy St Patrick’s Day Cookies! But if you’re in the mood for a no-bake, hard to mess up dessert, you’ve come to the right place. These Lucky Charms Rice Krispie Treats are the perfect solution!

What Do I Need to Make this Recipe? 

Ingredients 

Labeled ingredient shot
  1. Lucky Charms Cereal: You will need to separate the cereal from the marshmallows. Do NOT pour the hot marshmallow mixture into the cereal bowl with the Lucky Charms marshmallows still mixed into the cereal. Your lucky Charms marshmallows will melt and will mess up the look of your treat! 
  2. Mini Marshmallows: Use fresh marshmallows as they will melt better. You can also use jumbo marshmallows if preferred.
  3. Butter: This recipe calls for browning the butter to add an extra hit of flavor to your Rice Krispie treats, but feel free to omit this step if you don’t want to take the time to brown your butter. In that case, simply melt the butter, then add the marshmallows. 
  4. Sweetened Condensed Milk: This is not a standard ingredient in Rice Krispie Treats, but I love the flavor it gives! I highly recommend it.
  5. Vanilla Extract: This adds just a touch of sweetness. Feel free to sub out any other fun extracts you want, including cake batter flavor or mint. 
  6. Lucky Charms Marshmallows: I picked the marshmallows out of the cereal box, but they also sell bags of JUST the Lucky Charms marshmallows!

Tools

  1. 9×9 Baking Dish: You can use glass or nonstick. This makes for very thick rice krispie treats. Feel free to use a 9×13 pan for more plentiful, thinner treats!
  2. Pot: Use a pot that can fit 10 oz of mini marshmallows 

How to Make this Recipe

Step 1: Prepare

Bowl of Lucky Charms and Rice Krispies combined

Fill a large bowl with the Rice Krispies cereal and the Lucky Charms Cereal (but not the lucky charms marshmallows). Set aside.

Spray a 9×9 baking dish with nonstick spray. Set aside. 

 Step 2: Make the Marshmallow Mixture

In a large pot add the unsalted butter. Stir the butter continuously over low heat for about 10 minutes until the foam subsides, the milk solids gain a brown color, and the butter begins to smell nutty.

You have now browned your butter! If you want a faster recipe, you can skip the browning step and simply melt the butter and move on to step 4 right away.

Add the 10 ounce bag of marshmallows to the pot and continuously stir until they completely melt.

Add in the vanilla extract and sweetened condensed milk, stirring everything once again until combined.

Step 3: Make the Lucky Charms Rice Krispie Treats

Large mixing bowl filled with cereal and melted marshmallows

Rice Krispies pressed into an 8x8 pan

Remove the marshmallow mixture from the heat and pour over the bowl filled with the cereals. Use a large wooden spoon or rubber spatula to fold the ingredients together until evenly distributed.

While the mixture is still warm, add the Lucky Charms marshmallows and fold the two together again.

Transfer the mixture to the prepared baking dish and press into the pan evenly. Let the treats sit at room temperature for at least an hour before eating.

Cut and enjoy or store in a ziploc bag or a tightly sealed container for later. Enjoy! 

Expert Tips

  • Make sure to spray your hands or spoon with nonstick spray before trying to press your Lucky Charms Rice Krispie treats into the pan. This will keep the mess from sticking all over your fingers! 
  • Make sure to cook your marshmallow mixture on low heat. HIgh heat could lead to a burnt marshmallow mixture! 
  • Set aside some extra Lucky Charms marshmallows that you can press into the top of the treats after you have put them in the pan. This will add some extra decoration to the top. 
  • Make sure not to cook your marshmallow mixture on the stove for too long. Too long of a cook time will lead to chewy treats! 
  • Work quickly! The closer your treats get to room temperature, the harder they are to press into the pan. Don’t let them come to room temperature! 

How to Cut Rice Krispie Treats

It can be hard to cut your Rice Krispie treats perfectly considering they are such a sticky treat. But there are a few tips to make sure that you do your best! 

  1. Temperature: Make sure to allow the Lucky Charms Rice Krispie treats to chill fully before cutting into them or they will be a mess! You can even chill them in the fridge if desired.
  2. Cutting Board: If possible, remove your entire block of Rice Krispies from the pan at once. If you use nonstick spray, you should be able to use your hands to just remove the entire thing! Transfer this to parchment paper or a cutting board so that you can get an even cut. 
  3. Knife: I like to use a large knife that will cut across almost the entire pan at once! 
  4. Nonstick Spray: Spray your knife with nonstick spray so that the Rice Krispie treat mixture does not stick to the knife. 

Adaptations

Feel free to adapt this recipe any way that you think sounds delicious! Here are some ideas:
