Ingredients
- 4 cups Rice Chex Cereal
- 1 cup Green Candy Melts
- ¼ cup Creamy Peanut Butter
- ½ Tbsp Vegetable or Canola Oil
- ¾ to 1 cup Powdered Sugar
- ¼ cup Green M&Ms
- ¼ cup Shamrock Sprinkles (or Wilton Shamrock Mix)
- ¼ cup Shamrock Marshmallows (picked out of a Lucky Charms box)
Instructions
1. Prep the Cereal
Measure out 4 cups of Rice Chex cereal and place it into a large mixing bowl. Set aside.
2. Melt the Coating
In a medium microwave-safe bowl, combine the green candy melts, peanut butter, and oil. Microwave on high for 30 seconds. Stir, then continue microwaving in 15-second intervals until the mixture is completely smooth.
3. Coat the Cereal
Pour the melted green mixture over the cereal. Use a rubber spatula to gently fold the cereal until every piece is evenly coated. Be careful not to crush the Chex!
4. The Powdered Sugar Shake
Transfer the coated cereal into a large gallon-sized Ziploc bag. Pour in the powdered sugar. Seal the bag (leave some air inside) and shake vigorously until the cereal is white and well-coated.
5. Cool and Set
Spread the sugar-coated cereal onto a cookie sheet lined with wax or parchment paper. Let it sit for about 15–20 minutes until the coating has completely set.

6. Mix in the Luck
Once set, toss the cereal with the green M&Ms, shamrock sprinkles, and the Lucky Charms marshmallows. Serve immediately or store in an airtight container.
Expert Tips for Success
- Pick the Marshmallows: For the most festive look, pick only the green shamrock marshmallows out of the Lucky Charms box. If you’re in a rush, you can now find “marshmallows only” bags in many baking aisles!
- Don’t Overheat: Candy melts can be finicky. Always use short bursts in the microwave and stir thoroughly to prevent them from seizing or burning.
- The Sifter Hack: If you have too much excess powdered sugar in your bag, pour the chow into a colander and shake gently over the sink to remove the extra “dust” before adding the candies.
- Oil for Smoothness: The small amount of vegetable oil is the secret to getting a thin, even coat of candy melt that doesn’t clump too much.

Variations
- Minty Lucky Chow: Add a drop of peppermint extract to the melted candy mixture for a “thin mint” inspired flavor profile.
- Double Color Mix: Make one batch with green melts and one batch with white chocolate, then mix them together for a beautiful two-tone look.
- Pot of Gold: Add gold-wrapped chocolate coins or yellow M&Ms to the mix to symbolize the leprechaun’s treasure.
- Pretzel Punch: Add a cup of mini pretzels to the cereal mix before coating for an extra sweet-and-salty kick.
FAQ: St. Patrick’s Day Lucky Chow
Q: Can I use white chocolate chips instead of candy melts? A: Yes. You can use white chocolate chips and add a few drops of oil-based green food coloring. Note: Regular water-based food coloring will make the chocolate seize.
Q: How do I store this? A: Store in an airtight container at room temperature for up to 1 week. It can also be frozen for up to 2 months.
Q: Can I make this nut-free? A: Yes. Simply omit the peanut butter and replace it with an additional tablespoon of oil or butter to help the candy melts coat the cereal.
Q: Why is my puppy chow clumpy? A: This usually happens if the candy melt mixture is too thick or if you added the powdered sugar before the chocolate had a chance to cool slightly. Use the oil as directed to keep the mixture thin.
