5 Simple Ingredients To Start

This easy recipe starts with just a handful of simple ingredients–nothing tricky or fancy! 

• Lucky Charms. First up, we’re using Lucky Charms cereal in place of Rice Krispies/crisp rice cereal. I recommend the traditional varieties since they have such classic colored marshmallows, but feel free to try one of their seasonal or special edition varieties if you like!
• Butter. Next up is plenty of melted butter. This gets your melted marshmallows extra smooth and glossy, and keeps the cereal treats from drying out quickly.
• Mini Marshmallows. The small marshmallows melt easier than the big ones do, so they’re best for making homemade Lucky Charms treats.
• Vanilla & A Pinch Of Salt. My secret ingredients! These two play up the vanilla notes from the marshmallows, and balance the sweetness a bit. They shouldn’t end up tasting salty by any means, just not flat or too sweet.

How To Make Lucky Charms Rice Krispie Treats, Step By Step

As always, you can find the full recipe, with ingredient amounts, detailed instructions, and tips in the recipe card below.

1. Prep Your Pan. Line an 8-inch or 9-inch square pan with parchment paper or grease with a little butter. (For thinner bars, you can use a 9×13 or an 11×7 pan!)
2. Set Aside Cereal. Start by pouring the cereal into a large mixing bowl (use your biggest bowl!). If desired, set aside 1/3-1/2 cup of the Lucky Charms marshmallows to sprinkle on at the end.
3. Melt Butter & Marshmallows. Add butter and mini marshmallows to a saucepan, and stir over medium-low heat or medium heat. If your mixture doesn’t seem to be coming together, use a whisk to mix it. It should pull together easily!
4. Stir In Vanilla & Salt. Quickly stir in the vanilla extract and kosher salt and stir to combine.
5. Pour Marshmallow Mixture Over The Cereal. Next, pour the melted marshmallow mixture over the cereal and use a spatula to gently stir.
6. Stir To Coat. Use the spatula to gently mix until the cereal is evenly coated in the marshmallow mixture (it will be sticky!)
7. Pat Into Pan. Transfer the cereal mixture to your prepared baking dish and use very gentle pressure to pat the mixture into an even layer. Sprinkle with reserved Lucky Charms marshmallows if desired.
8. Cool & Cut. Let the Lucky Charms Treats cool and set before cutting into 9 large squares, 12 rectangles or 16 small squares.
9. Store. Transfer leftover cereal bars to an airtight container or bag and store at room temperature 4-5 days. They’ll stay even more fresh if you individually wrap the squares in plastic wrap first!

Can I Just Use The Microwave? Yep! Some people prefer to melt the marshmallows and butter in the microwave. If you do, too, add marshmallows and butter to a large microwave safe bowl and melt in 20-30 second increments, stirring after each interval until the marshmallow mixture is smooth.
