Tips & Tricks When Making These Lucky Charms Rice Krispie Treats
- Use fresh marshmallows and don’t overcook them! If you overcook the marshmallows your bars will become incredibly sticky
- Low heat prevents scorching and helps keep the melted marshmallows smooth
- Be ready to work quickly. Once the butter is browned you need to immediately add the salt and vanilla and then marshmallows. When the marshmallows are melted you need to add the cereal right away and then once mixed move into the 9×9 pan right away so that you get them formed in the pan before they harden.
- Bring extra color to your bars– reserve a few Lucky Charms marshmallows to put on top of your bars when they are still warm, push them down lightly and you will have bright, colorful bars to serve!

Variations To This Recipe
- If you don’t have unsalted butter you can use salted butter and just cut the added salt in half
- You can use regular sized marshmallows but they may take a little longer to become soft/gooey
- Be very attentive when browning your butter, after the butter melts it browns fairly quickly and can burn so it’s important to watch it closely and constantly stir. This article talks a little more about the art of browning butter if you are interested.
- Try drizzling melted white chocolate on top for an extra sweet treat

Storage & Serving Suggestions
Store in an airtight container at room temperature for up to 4 days.
Wrap in plastic wrap or place between layers of wax paper to prevent sticking.
They are perfect for sharing at birthday parties or packing as a school snack!
These Lucky Charms Rice Krispie Treats are the best thing for a quick, tasty treat with a bit of nostalgia.
