Easy Christmas Snack Mix

Christmas puppy chow - also called muddy buddies - is one of those addictive holiday snacks where Chex cereal gets coated in melted chocolate and peanut butter, shaken in powdered sugar until every piece is covered, then mixed with festive candy and treats to create this sweet, crunchy, chocolatey mix that's impossible to stop eating. The technique is straightforward once you understand that melting the chocolate and peanut butter completely before coating the cereal ensures even distribution, and that shaking in a bag with powdered sugar creates thorough coating without crushing the cereal. What makes this particularly appealing is how it requires no baking, comes together in about ten minutes of active work, feeds a crowd for minimal cost, and can be customized endlessly with different mix-ins from M&Ms to pretzels to caramel chips depending on what you have or what sounds good.

I started making puppy chow about fifteen years ago and initially struggled because I tried to shake the cereal in powdered sugar while it was still warm, which made the sugar melt into sticky coating instead of staying powdery and white. After learning that the cereal must cool to room temperature before adding to the sugar bag, and that shaking vigorously in a sealed bag creates even coating without crushing pieces, it became foolproof. Now I make multiple batches every Christmas with different mix-ins because it's one of those treats that disappears immediately at parties and makes excellent last-minute gifts.

Ingredients and What Makes Them Essential

For the Puppy Chow Base:

• Rice Chex Cereal (9 cups, about one 12-ounce box): Rice Chex has the perfect light, crunchy texture and distinctive square shape with holes that hold coating well. You can use chocolate Chex, corn Chex, or other varieties, but rice Chex is traditional.
• Semi-Sweet Chocolate Chips (1½ cups): Chocolate provides the main flavor. Semi-sweet is traditional and balances the sweetness, but you can use milk chocolate or dark chocolate.
• Creamy Peanut Butter (½ cup): Peanut butter adds richness and helps the chocolate coating adhere to the cereal. Use regular creamy peanut butter like Jif or Skippy, not natural peanut butter which separates.
• Unsalted Butter (¼ cup, ½ stick): Butter adds richness and helps thin the chocolate-peanut butter mixture for easier coating.
• Pure Vanilla Extract (1 teaspoon): Vanilla enhances the chocolate flavor. Optional but recommended.
• Powdered Sugar (1½ to 2 cups): Powdered sugar creates the characteristic white coating. Start with 1½ cups and add more if needed for thorough coverage.

For the Mix-Ins (Optional but Festive):

• Red and Green M&Ms (1 cup): Adds festive color and chocolate crunch.
• Chocolate Covered Pretzels (1 cup): Provides salty-sweet contrast. Make your own by drizzling melted white chocolate over mini pretzels and adding sprinkles.
• Salted Caramel Chips or Butterscotch Chips (½ cup): Adds different flavor dimension.

Step-by-Step Instructions

Melt Chocolate Mixture:

Place 1½ cups of chocolate chips, ½ cup of peanut butter, and ¼ cup of butter in a medium saucepan over low heat. Stir frequently with a rubber spatula or wooden spoon, scraping the bottom and sides to prevent scorching. Continue stirring for about 4 to 5 minutes until everything is completely melted and smooth. The mixture should be uniform in color with no chunks of chocolate or peanut butter remaining. Remove from heat and stir in 1 teaspoon of vanilla extract. Mix well.

Alternative Microwave Method:

Place chocolate chips, peanut butter, and butter in a large microwave-safe bowl. Microwave on 50% power in 30-second intervals, stirring thoroughly between each interval, until completely melted and smooth. This usually takes 2 to 3 intervals. Stir in vanilla.

Coat the Cereal:

Place 9 cups of Rice Chex cereal in a very large mixing bowl (at least 4-quart capacity to allow room for stirring). Pour about half of the melted chocolate-peanut butter mixture over the cereal. Use a rubber spatula to gently fold and stir, coating as many pieces as possible. Pour in the remaining chocolate mixture and continue folding gently until all the cereal pieces are evenly coated. Work carefully to avoid crushing the cereal - gentle folding is key.

Add Powdered Sugar:

Place 1½ cups of powdered sugar in a gallon-sized zip-top bag. Let the chocolate-coated cereal cool for about 5 minutes at room temperature - it should be barely warm to the touch, not hot. If you add hot cereal to powdered sugar, the sugar will melt into sticky coating instead of staying powdery. Pour all the coated cereal into the bag with the powdered sugar. Seal the bag tightly, removing as much air as possible. Shake vigorously for about 1 to 2 minutes, tossing and turning the bag to coat all pieces thoroughly. The cereal should be completely covered with white powdered sugar.

Set:

Line a large baking sheet with parchment paper or wax paper. Pour the sugar-coated cereal out of the bag onto the prepared baking sheet, spreading it into a single layer. Let it sit at room temperature for about 30 minutes to set and dry. The coating will firm up during this time. If you're in a hurry, refrigerate for about 15 minutes to speed the process.

Prepare Mix-Ins (Optional):

While the cereal sets, prepare any mix-ins you're using. For chocolate-covered pretzels, place 2 ounces of white chocolate chips or candy melts in a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until melted and smooth. Drizzle melted chocolate over 15 to 20 mini pretzels arranged on parchment paper. Immediately sprinkle with holiday sprinkles before the chocolate sets. Let sit for about 30 minutes until the chocolate hardens.

Add Mix-Ins and Serve:

Once the puppy chow is set and the pretzels (if making) are hardened, combine everything in a large bowl. Add 1 cup of red and green M&Ms, the chocolate-covered pretzels, ½ cup of salted caramel chips, or whatever mix-ins you're using. Toss gently to distribute evenly. Serve immediately or store in an airtight container.

Pin it

My nephew who's picky about textures and refuses to eat anything "weird" was suspicious of puppy chow because of the name and the appearance. After I convinced him to try one piece, he ate an entire bowl and asked what made the "white cereal candy stuff" so good. Now he requests it specifically for family gatherings. Getting the picky eater to love something through the right balance of sweet and crunchy feels like a small victory.

Understanding Why Rice Chex Works Best

Rice Chex cereal is ideal for puppy chow because of its specific characteristics. The square lattice shape with multiple holes provides surface area for chocolate coating to adhere while creating pockets that hold powdered sugar. The light, crispy texture stays crunchy under the coating rather than becoming soggy. The neutral rice flavor doesn't compete with chocolate and peanut butter. The size is perfect - small enough to be snackable, large enough to maintain integrity during coating and shaking. Other cereals like cornflakes would break too easily, while smaller cereals like Cheerios don't have enough surface area for coating. You can use chocolate Chex for more chocolate flavor or corn Chex for slightly different taste, but rice Chex is the classic choice.

The Importance of Cooling Before Sugar

The instruction to let the chocolate-coated cereal cool before adding to powdered sugar isn't optional - it fundamentally affects the final texture. Powdered sugar is essentially very finely ground granulated sugar mixed with a small amount of cornstarch. When hot or warm chocolate-coated cereal goes into powdered sugar, the heat melts the sugar, which then dissolves into the chocolate coating and creates sticky, glossy surface rather than the characteristic dry, powdery white coating. Cool cereal (just barely warm or room temperature) doesn't melt the sugar. The powdered sugar adheres to the chocolate coating mechanically rather than dissolving, creating that distinctive white, powdery appearance and matte finish that makes puppy chow recognizable. This cooling step takes only 5 minutes but makes the difference between correct texture and sticky mess.

Why Regular Peanut Butter Works Better Than Natural

The recipe specifies regular creamy peanut butter rather than natural peanut butter, and this matters. Regular peanut butter (Jif, Skippy, Peter Pan) contains stabilizers and emulsifiers that keep the peanut oil from separating. These same properties help the chocolate-peanut butter mixture stay smooth and homogeneous, creating even coating. Natural peanut butter contains just peanuts and salt - the oil separates and must be stirred back in. When melted with chocolate, natural peanut butter can separate, creating greasy coating that doesn't adhere properly to cereal. The stabilizers in regular peanut butter also help the mixture stay fluid longer, making coating easier. For puppy chow, regular peanut butter creates better results.

Storage, Gifting, and Shelf Life

Puppy chow stores exceptionally well, making it perfect for advance preparation and gifting. Store in an airtight container at room temperature for up to 1 week, or refrigerate for up to 2 weeks. The cereal stays crunchy remarkably well as long as it's protected from humidity. For gifting, pack into clear cellophane bags tied with ribbon, decorative tins, or mason jars. Include a label with the name and ingredients (especially note peanuts for allergy concerns). For freezing, store in airtight containers or freezer bags for up to 3 months. Thaw at room temperature or in the refrigerator overnight. The texture remains excellent after freezing. Make multiple batches and freeze some for last-minute gifts or unexpected guests.

Variations and Different Flavor Profiles

While classic chocolate-peanut butter is traditional, you can create countless variations. For cookies and cream, use white chocolate instead of chocolate chips and fold in crushed Oreos. For peppermint, use white chocolate and add crushed candy canes. For s'mores, add mini marshmallows and graham cracker pieces. For turtle, use caramel chips instead of chocolate and add pecans. For peanut butter cup, use milk chocolate and add chopped peanut butter cups. For red velvet, use white chocolate with red food coloring and add white chocolate chips. For birthday cake, use funfetti cake mix in place of some powdered sugar and add sprinkles. For sunflower seed version (nut-free), substitute sunflower seed butter for peanut butter. Each variation maintains the coating technique while creating different flavors.

Troubleshooting Common Problems

When puppy chow doesn't turn out right, there's usually a fixable cause. If the coating is sticky instead of powdery, you added hot cereal to the sugar - let cereal cool first. If chocolate won't melt smoothly, you used too-high heat - use low heat and stir constantly. If cereal is crushed, you stirred too vigorously - fold gently. If coating is uneven, you didn't shake long enough in the bag - shake thoroughly. If it's too sweet, reduce powdered sugar to 1 cup next time. If chocolate seized and became grainy, water got in - keep everything dry. If it became soggy after storage, humidity got in - store in truly airtight container. Most issues relate to temperature management, gentle handling, or storage conditions.

Pin it

After making puppy chow probably a hundred times over the past fifteen years, it's become one of my most reliable holiday treats because it consistently disappears at parties, makes excellent last-minute gifts, and can be customized endlessly based on what I have or what sounds good. I appreciate how something so simple - cereal, chocolate, peanut butter, sugar - creates something genuinely addictive that both kids and adults love. The no-bake convenience removes stress during busy holiday baking seasons. Knowing the simple secrets - cool before sugar, fold gently, shake thoroughly - transforms something that could be sticky or crushed into something with perfect texture every time. This represents exactly what holiday treats should be - impressive enough to gift, genuinely delicious rather than just festive-looking, practical enough to make in quantity, and versatile enough that you can create different versions for various occasions or preferences throughout the season.
