Ingredients for Magical Lucky Charms Rice Krispie Bars
For the Treats
- 16 ounces marshmallows (large or small)
- ½ cup unsalted butter, plus more for greasing the pan
- 1 teaspoon vanilla extract
- 1 cup Rice Krispies cereal
- 6 cups Lucky Charms cereal
- ½ teaspoon salt
How to Make Magical Lucky Charms Rice Krispie Bars
Step 1: Prepare the pan
Prepare a 9″ x 9″ pan by greasing it with butter, nonstick cooking spray, or lining it with parchment paper to prevent sticking. Keep in mind that using a square pan will yield thicker treats, while a rectangular pan will yield thinner treats.
Step 2: Melt the marshmallows
Coat a large mixing bowl with cooking spray, then place the marshmallows in the bowl. Microwave in 30-second intervals until they are melted and puffy. Alternatively, melt them in a large saucepan on the stovetop.
Step 3: Add butter and salt
Combine the butter and salt with the melted marshmallows until smooth. Grease spatula with cooking spray for easier mixing.
Step 4: Mix in cereals
Set aside some of the colorful Lucky Charms marshmallows for garnishing. Gradually mix Lucky Charms and Rice Krispies cereals into the melted marshmallow mixture, adding one cup at a time and stirring well after each addition.
Step 5: Press into pan
Transfer the cereal mixture to the prepared baking dish and press into an even layer using a spatula. Coat clean hands with cooking spray to firmly press the mixture into the corners.
Step 6: Add topping and set
Sprinkle the saved Lucky Charms marshmallows over the warm treats. Allow them to cool in the pan until reaching room temperature, or freeze for 20 minutes for a quick set.
Step 7: Cut and serve
Use a knife to loosen the treats from the edges of the pan, then lift them out and cut into 9 equal squares. Serve right away or store for later.
Storage Tips
After making a batch of Lucky Charms Rice Krispie Treats, it’s important to store them properly to maintain their best texture and flavor. These treats are best kept in an airtight container at room temperature. If you need to stack them, place parchment paper between the layers to prevent sticking. Surprisingly, these treats actually improve overnight as the Lucky Charms marshmallows soften slightly, creating that perfect chewy contrast to the crispy cereal. Avoid refrigerating them unless your kitchen is extremely hot, as the cold temperature can make them too hard.
For longer storage, consider wrapping individual squares in plastic wrap and then freezing them in a larger container. This method allows you to enjoy these delightful treats for up to a month. Whether you’re hosting a party, packing them for a picnic, or just indulging in a sweet treat at home, proper storage will help keep your Lucky Charms Rice Krispie Treats fresh and delicious for as long as possible.
Ingredient Substitutions
If you’re looking to make a slight adjustment to these Lucky Charms Rice Krispie Treats, consider swapping out the unsalted butter for salted butter and reducing the added salt in the recipe. The salted butter can bring a subtle savory note that complements the sweetness of the marshmallows and cereals. Just be mindful of the overall saltiness level, especially if you are using smaller marshmallows that might already contain some salt.
For a potential substitution in the cereal department, you could experiment with using a different type of crispy cereal in place of the Rice Krispies. Cornflakes or crushed graham crackers could provide a similar crunchiness while adding a unique flavor profile to the treats. This swap allows for some creativity in customizing the taste and texture of the bars while maintaining the nostalgic aspect of the original recipe. Just keep in mind the cereal’s texture and how it will interact with the marshmallow mixture to ensure the treats hold together well.
Serving Suggestions
Transform these Lucky Charms Rice Krispie Treats into a whimsical dessert by cutting them into fun shapes using cookie cutters – think shamrocks for St. Patrick’s Day, hearts for Valentine’s, or stars for the Fourth of July. Add a sprinkle of rainbow confetti on top for an extra pop of color before serving. Serve these treats on a platter alongside other childhood favorites like chocolate chip cookies and brownies for a nostalgic dessert table that will delight guests of all ages.
For a more elegant presentation, drizzle these Lucky Charms Rice Krispie Treats with a luscious white chocolate ganache before serving. The creamy sweetness of the ganache pairs perfectly with the crispy-chewy texture of the treats, elevating them to a dessert fit for any special occasion. To store leftovers, keep them in an airtight container at room temperature, stacking them with parchment paper in between layers to prevent sticking. Enjoy the treats within a few days for the best texture, or wrap individual squares in plastic wrap and freeze for up to a month for a sweet treat anytime you need a nostalgic pick-me-up.
