Why You’ll Love This Puppy Chow

• No-Bake & Fast: Ready to eat in under 15 minutes.
• Crowd Favorite: Perfectly portionable for large groups or party favors.
• Minty & Fresh: The combination of mint chocolate and green candy melts is seasonally perfect.
• Kid-Friendly: Children love helping “shake” the bags to coat the cereal in powdered sugar.

Ingredients

• 9 cups Rice Chex cereal
• 1 cup Semi-sweet Chocolate Chips
• ½ cup Creamy Peanut Butter (or Sunflower butter for nut-free)
• ¼ cup Unsalted Butter
• 1 tsp Peppermint Extract (optional, for extra minty flavor)
• 1 ½ cups Powdered Sugar
• 1 cup Green Candy Melts
• 1 cup Lucky Charms Marshmallows (the “charms” only!)
• Optional: Green and gold sprinkles or Mint M&Ms

Instructions

1. Prep the Cereal

Measure out the Rice Chex cereal into a very large mixing bowl. Set aside.

2. Melt the Chocolate Base

In a microwave-safe bowl, combine the chocolate chips, peanut butter, and butter. Microwave in 30-second increments, stirring in between, until the mixture is completely smooth. Stir in the peppermint extract if using.

3. Coat the Cereal

Pour the melted chocolate mixture over the cereal. Use a large spatula to gently fold the cereal until every piece is evenly coated in chocolate. Be careful not to crush the Chex!

4. The Powdered Sugar Shake

Place the powdered sugar in a large gallon-sized Ziploc bag. Add the chocolate-coated cereal to the bag. Seal it tightly (leaving some air inside) and shake vigorously until the cereal is white and well-coated.

5. Add the Green Flare

Melt the green candy melts according to the package directions. Drizzle the melted green candy over the powdered sugar-coated cereal (or toss a portion of the cereal in the green melts for a bi-color look).

6. Mix in the Magic

Once the green chocolate has set, gently stir in the Lucky Charms marshmallows and any extra sprinkles or M&Ms. Spread the mixture out on a baking sheet to cool completely before storing.

Expert Tips for Success

• Don’t Over-Melt: Chocolate and candy melts can burn easily. Always use short bursts in the microwave and stir thoroughly.
• The Sifter Trick: If you have too much excess powdered sugar at the bottom of your bag, pour the finished puppy chow into a large colander/sieve and shake gently over the sink to remove the “snow” before adding the marshmallows.
• Marshmallow Timing: Never add the marshmallows while the chocolate is still warm, or they will melt and lose their shape!
• Double Bagging: If you’re letting kids do the shaking, double-bag the powdered sugar to prevent a “white cloud” explosion in your kitchen.

Variations

• Nut-Free Version: Use a soy-nut butter or extra butter/chocolate in place of the peanut butter to make it school-safe.
• Pot of Gold Chow: Use yellow candy melts and gold edible glitter or sprinkles to lean into the “Leprechaun’s Gold” theme.
• Extra Minty: Use Mint-flavored chocolate chips (like Andes chips) instead of standard semi-sweet chips.
• White Leprechaun: Use white chocolate chips tinted with green oil-based food coloring for a lighter, creamier version.
