I love using both Lucky Charms cereal and Rice Krispies cereal because the Rice Krispies cereal gives these bars the texture of an original Rice Krispies treat and the Lucky Charms cereal gives these bars a special touch, especially the magical marshmallows! Both kids and adults will love these Lucky Charms treats!
You want to be sure to coat the cereal evenly with the melted marshmallows. The marshmallow and cereal ratio is just perfect.
I love adding extra Lucky Charms marshmallows on top- this is totally optional. It’s my favorite part because who doesn’t love Lucky Charms marshmallows?! They also add some color to these treats and make them look extra magical!
All of the Lucky Charms marshmallows inside the cereal mixture adds a burst of sweetness and a little crunch. You can pick out your favorite shapes and add as many or as little as you want. Add these Lucky Charms Rice Krispies Treats to your kids lunch box, or make them for birthday parties or St. Patrick’s Day!
INGREDIENTS TO MAKE LUCKY CHARMS RICE KRISPIES TREATS
- Butter
- Marshmallows
- Lucky Charms cereal
- Rice Krispies cereal
HOW TO MALKE LUCKY CHARMS RICE KRISPIES TREATS
- Line a 13 x 9 inch baking pan with parchment paper and lightly coat with nonstick cooking spray.
- In a large pot over low heat, melt the butter. Once the butter has melted, stir in the marshmallows and stir constantly until melted. Be sure not to let the marshmallows brown, they will burn quickly.
- Once the marshmallows are melted remove from heat and stir in the cereal until evenly coated.
- Pour the mixture into the prepared pan and press evenly (coat a spatula with nonstick cooking spray on both sides or coat your hands so the mixture doesn’t stick). Add Lucky Charms marshmallows to the tops of the treats (optional). Allow to cool for a few minutes and slice into bars.
THESE LUCKY CHARMS RICE KRISPIES TREATS ARE
- Better than your typical marshmallow treat! The combination of the two cereals really make these treats extra special.
- No-bake treats, require only 4 ingredients and take 15 minutes to make!
- Easy enough for kids to make. They can help stir the melted marshmallows and cereals together or add the Luck Charms marshmallows on top.
- Perfect for St. Patrick’s Day or lunch box treats. They also make great snacks!
- Magically delicious 😉
TIPS
- When pressing the cereal mixture onto the prepared baking sheet, be sure to coat your hands or both side of a spatula to avoid getting your hands sticky!
- You can cut up these bars as little or as big as you wish. You can make them into square or rectangle shapes depending on how many bars you want.
- Dip the bottoms of these bars in melted white chocolate! They will resemble the classic Lucky Charm Treats that you can buy at the store.
- Add green sprinkles to the top of the prepared treats to make these extra festive for St. Patrick’s Day!
LEFTOVERS
Be sure to store any leftover treats in an airtight container at room temperature. I like to layer the bars with a sheet of wax paper in between layers so they don’t stick to each other. They will stay fresh for up to 3 days. I don’t recommend refrigerating these treats because they tend to get rock hard.
