Christmas puppy chow goes by a dozen names depending on where in the Midwest you grew up: muddy buddies, reindeer chow, monkey munch. The recipe is the same everywhere. Melt chocolate chips and peanut butter together, coat Chex cereal in the mixture, then shake it all in powdered sugar until every square is covered in a sweet, dusty shell. The name "puppy chow" comes from its resemblance to dry dog food, which admittedly does not sound appetizing, but one handful converts every skeptic.
This version adds red and green sprinkles and holiday M&Ms to make it unmistakably Christmas. The recipe is dead simple and requires zero baking, which makes it one of the most practical holiday treats you can bring to a party or package as a gift. The coating ratio here leans heavy on the chocolate and peanut butter so every piece is fully covered, not patchy.
Equipment
Instructions
Tap each step to track your progress
- 1
Measure the Chex cereal into a very large mixing bowl. The bowl needs to be big enough to toss the cereal without pieces flying out. A large stockpot works if you do not have a bowl large enough.
- 2
Combine the chocolate chips, peanut butter, and butter in a medium microwave-safe bowl. Microwave in 30-second intervals, stirring after each, until completely smooth. This usually takes 90 seconds total. Do not overheat or the chocolate will seize. Alternatively, melt in a saucepan over low heat, stirring constantly.
- 3
Stir the vanilla extract and salt into the melted chocolate mixture until evenly incorporated.
- 4
Pour the chocolate-peanut butter mixture over the Chex cereal. Using a large silicone spatula, fold gently until every piece is evenly coated. Work carefully here; the goal is full coverage without crushing the cereal into crumbs. Take your time and scrape the bottom of the bowl.
- 5
Add the sifted powdered sugar to a large paper grocery bag or a gallon-size zip-top bag. Transfer the coated cereal into the bag, seal the top, and shake vigorously for 60 seconds until every piece is thoroughly coated in powdered sugar. If the coating looks thin, add another 1/2 cup of powdered sugar and shake again.
- 6
Spread the coated puppy chow onto a parchment-lined baking sheet in a single layer. Let it cool and set at room temperature for about 10 minutes, or speed it up in the refrigerator for 5 minutes. The chocolate coating should feel dry to the touch, not tacky.
- 7
Transfer the cooled puppy chow back to the large bowl. Add the holiday M&Ms and sprinkles and toss gently to distribute evenly throughout the mix.
Tips & Tricks
Use rice Chex, not corn or wheat
Rice Chex holds up best to the wet chocolate coating without getting soggy. Corn Chex works in a pinch but tends to get softer. Wheat Chex absorbs too much moisture and turns mushy. Stick with rice.
Sift the powdered sugar
Lumpy powdered sugar creates clumps that do not distribute evenly. A quick pass through a fine-mesh sieve takes 30 seconds and makes the coating noticeably smoother and more uniform.
Do not skip the vanilla
Vanilla rounds out the chocolate and peanut butter flavor and prevents the mix from tasting one-dimensional. Without it, the coating tastes flat.
Make it ahead for gifting
Puppy chow actually improves after sitting for a few hours because the coating firms up and the powdered sugar adheres better. Make it the morning of a party or a full day ahead. Package in mason jars, cellophane bags, or tins lined with wax paper.
Use real peanut butter, not natural
Conventional peanut butter (like Jif or Skippy) contains stabilizers that help it blend smoothly with the melted chocolate. Natural peanut butter separates and creates an oily, uneven coating that slides off the cereal.
Troubleshooting
The chocolate coating is patchy and uneven
You either did not use enough chocolate mixture or tried to stir too quickly and broke cereal pieces before they were coated. Pour the melted chocolate slowly and fold gently. If pieces at the bottom are over-coated and pieces at the top are bare, you need a bigger bowl so you can fold properly.
The powdered sugar won't stick
The chocolate coating cooled too much before you added the powdered sugar. The cereal needs to be warm and slightly tacky for the sugar to adhere. If it has already cooled, shake it in the bag anyway, then drizzle a tablespoon of melted chocolate over the cereal, toss, and shake with more powdered sugar.
The cereal is crushed and crumbly
You stirred too aggressively. Chex is fragile, especially once wet. Use a folding motion, not a stirring one, and use a spatula, not a spoon. Some breakage is inevitable, but you should have mostly intact squares.
It tastes too sweet
Cut the powdered sugar to 1 1/2 cups and use dark chocolate chips instead of semisweet. You can also increase the salt to 1/2 teaspoon. The salt makes a significant difference in balancing the sweetness.
Variations
White Chocolate Reindeer Chow
Replace the semisweet chocolate chips with white chocolate chips and reduce the peanut butter to 1/2 cup. The flavor is sweeter and milder. Toss in dried cranberries and crushed pretzels instead of M&Ms for a red-and-gold color scheme.
Nut-Free School-Safe Version
Swap the peanut butter for sunflower seed butter (such as SunButter) and use nut-free chocolate chips. The sunflower seed butter gives a slightly more earthy flavor, but the texture and coating are nearly identical. Check M&M labels for nut-free processing if needed for allergy safety.
Dark Chocolate Peppermint Puppy Chow
Use dark chocolate chips (60% cacao) instead of semisweet, omit the peanut butter, and add 1/2 teaspoon peppermint extract to the melted chocolate. Replace M&Ms with crushed candy canes. The result is richer, less sweet, and intensely minty.
Vegan Puppy Chow
Use dairy-free chocolate chips and replace the butter with refined coconut oil. Swap in a plant-based peanut butter (most are already vegan, but check for honey). Skip the M&Ms and use vegan sprinkles and dairy-free chocolate candies. The powdered sugar coating works exactly the same.
Serving & Gifting
Serve Christmas puppy chow in a large bowl at parties and let people scoop their own portions. It works well in individual cups or cones made from parchment paper for a buffet-style setup. Pair with hot chocolate, coffee, or cold milk. For a cookie swap, pack it into clear cellophane bags tied with ribbon, which shows off the red and green mix-ins.
Storage & Freezing
Store in an airtight container at room temperature for up to 2 weeks. Do not refrigerate; the condensation makes the powdered sugar coating dissolve into a sticky paste. The puppy chow freezes well for up to 2 months in a freezer bag with the air pressed out. Thaw at room temperature in the sealed bag, then toss with an extra dusting of powdered sugar to refresh the coating.
Common Questions
What is the difference between puppy chow and muddy buddies?
They are the same recipe. "Muddy buddies" is the trademarked name General Mills uses on the Chex cereal box. "Puppy chow" is the Midwestern colloquial name that predates the branding. Both refer to Chex cereal coated in chocolate, peanut butter, and powdered sugar.
Can I make Christmas puppy chow without peanut butter?
Yes. Sunflower seed butter, almond butter, or cookie butter (Biscoff spread) all work as direct substitutes. Sunflower seed butter is the best nut-free option for allergy concerns. Use the same amount called for in the recipe.
How far in advance can I make puppy chow?
You can make it up to 2 weeks ahead if stored in an airtight container at room temperature. The coating firms up nicely overnight. If the powdered sugar looks faded after a few days, toss it with a few extra tablespoons of sifted powdered sugar before serving.
Can I use chocolate candy melts instead of chocolate chips?
You can, but the flavor will be noticeably waxy and less chocolatey. Real semisweet chocolate chips produce a much better result. If you want a smoother melt, add a teaspoon of coconut oil to the chocolate chips instead of switching to candy melts.
Is puppy chow gluten-free?
Rice Chex cereal is labeled gluten-free by General Mills, which makes the base recipe gluten-free as long as your other ingredients (chocolate chips, peanut butter, powdered sugar) are also certified gluten-free. Always check labels if cooking for someone with celiac disease.
Why is my puppy chow sticky and clumping together?
The cereal was still too warm when you added the mix-ins, or you did not use enough powdered sugar. Spread the coated cereal on a baking sheet to cool completely before adding M&Ms or sprinkles. If it is clumping, shake it with more powdered sugar to absorb excess moisture from the chocolate coating.
