Ingredients You’ll Need
- 3 tablespoons butter
- 1 package (10 oz) marshmallows
- 6 cups Rice Krispies cereal
- 2 cups Lucky Charms cereal
- Green food coloring (optional)
- Sprinkles (optional)
I keep extra marshmallows on hand, because who doesn’t top off the pan? Also, use fresh Lucky Charms for maximum marshmallow-to-grain ratio — stale cereal ruins the vibe.
How to Make (Step-by-Step)
1. Melt the butter
In a large saucepan, melt the butter over low heat. I use low heat to avoid burning the butter. Do you like when the butter sizzles too much? No? Neither do I.
2. Add marshmallows (and color if you want)
Add the marshmallows and stir constantly until completely melted. If you want festive color, add green food coloring now and stir until the color blends evenly. I add one or two drops; the goal is mood, not theatrical neon.
3. Mix in the cereals
Remove the pan from the heat and add the Rice Krispies and Lucky Charms. Stir quickly but gently until well combined. The marshmallow cools fast, so move briskly. I throw in the Lucky Charms last so the cereal keeps some crunch and the marshmallows inside the cereal don’t dissolve entirely.
4. Press into the pan
Press the mixture into a greased 9×13 inch pan. Use a piece of parchment or a buttered spatula to press without squishing all the marshmallow air out — you want chew, not a hockey puck.
5. Cool and finish
Allow the pan to cool, then cut into squares and top with sprinkles if desired. I sometimes add an extra drizzle of melted white chocolate for a fancy touch. Fancy tastes better on social media, FYI.
Ingredient and Method
I always keep the ingredient list short and predictable because that’s the charm. The method stays classic: melt, mix, press, cool. This approach gives consistent results and saves my kitchen from chaos. If you control temperature and timing, you control texture — crunchy Lucky Charms bits plus soft marshmallow equals perfection.
Pro Tips for the Best Results
- Use low heat when melting marshmallows to prevent scorching.
- Work quickly once the marshmallows melt; they firm up fast.
- Don’t over-press into the pan — you want them dense but still chewy.
- Reserve extra Lucky Charms to sprinkle on top for presentation.
- Grease hands or spatula to press the mixture without stickiness.
- Store airtight to keep the cereal from going stale quickly.
- For extra chew, add a tablespoon of light corn syrup when melting marshmallows.
- If you love texture, fold half the Lucky Charms in and sprinkle the rest on top to keep more crunch.
Fun Variations & Topping Ideas
Variations:
- Chocolate Lover’s: Add 1 cup mini chocolate chips into the warm mix.
- Nutty: Stir in 1/2 cup chopped peanuts or almonds for salt and crunch.
- Fruity: Mix in dried cranberries or chopped dried strawberries.
- St. Patrick’s Day: Use green food coloring and extra green sprinkles for holiday vibes.
- Gluten-free: Use a certified gluten-free crispy rice cereal that mimics Rice Krispies.
Toppings:
- Drizzled white or dark chocolate
- Extra Lucky Charms on top
- Rainbow sprinkles
- Sea salt flakes for a salty-sweet contrast
- Mini M&M’s for an extra layer of color and chocolate
Storing and Reheating
- Refrigerating: Store in an airtight container at room temperature for up to 3 days. If your kitchen does hot summers, pop them in the fridge to avoid melting into a cereal soup.
- Freezing: Wrap individual squares in plastic wrap and freeze up to 6 weeks. Thaw at room temperature for 15–20 minutes before serving.
- Reheating: Warm gently in the microwave (10–15 seconds) to soften and renew chew. Don’t overdo it — you’ll melt all the texture away.
I always label a frozen batch with the date because I have the memory of a goldfish when it comes to leftovers.
Leftover ideas
- Cereal Bars: Chop squares into bit-sized pieces and toss into yogurt.
- Ice Cream Topping: Crumble over vanilla ice cream for instant party-level dessert.
- Milk Mix-Ins: Stir a few crumbles into milk for a cereal mashup shake.
- Trail Mix: Mix crumbled treats with nuts and dried fruit for a sweet-salty snack.
- S’mores Swap: Use a square instead of graham crackers with chocolate and marshmallow. Yes, it’s as decadent as it sounds.
Frequently Asked Questions (FAQ)
How long do these keep?
They keep fresh for 3 days at room temperature in an airtight container, or up to 6 weeks frozen. I rarely manage to keep them that long, honestly.
Can I make these ahead of time?
Yes. Make them the day before — they taste great the next day. If you want crispier Lucky Charms, add some right before serving.
Can I use mini marshmallows instead of a marshmallow bag?
Yes. About 4 cups mini marshmallows equals the 10 oz bag. Measure loosely; marshmallows compress weirdly.
Can I substitute the Rice Krispies?
Yes, but expect a texture change. Use a similar puffed rice cereal for closest results. If you try a granola, the treat becomes a different beast — still tasty, but different.
What if my marshmallows burn?
If they scorch, toss them and start over. Burnt marshmallows taste bitter and ruin the whole batch. I learned this the hard way once. Never again.
