Muddy Buddies are Rice Chex coated in melted chocolate and peanut butter, then shaken in powdered sugar until every piece is covered. The whole thing takes 25 minutes, uses no oven, and costs next to nothing. If you need something sweet for a crowd tonight and your pantry has cereal, peanut butter, and chocolate chips, you’re already there.
Before you start
Two things actually matter here. First, don’t rush the chocolate melt. Whether you’re using the microwave or a double boiler, go slow — overheated chocolate turns grainy and seizes, and there’s no fixing it once it does. Short bursts, stir between each one, stop when it’s mostly melted and let residual heat finish the job. Second, let the coated cereal cool for a few minutes before you add the powdered sugar. If it’s still hot when it hits the bag, the sugar dissolves into a paste instead of a dry coating. A couple of minutes on the sheet pan is enough — you’re not waiting for it to go cold, just for the steam to stop rising.
Ingredient notes
- Chocolate chips: Semi-sweet is standard, but milk chocolate works fine and gives a sweeter result. A rough-chopped chocolate bar from the baking aisle melts more evenly than chips and is often cheaper per ounce.
- Peanut butter: Shelf-stable, no-stir peanut butter (Jif, Skippy, store brand) blends into the chocolate smoothly. Natural peanut butter can separate and make the coating oily — if that’s what you have, warm it and stir it very well before using.
- Butter: Unsalted or salted both work. If you’re out of butter entirely, a neutral oil like vegetable or canola does the job — use the same amount.
- Powdered sugar: No substitutes here; granulated sugar won’t coat the same way. If yours has clumped, sift it before adding or you’ll get uneven patches.
- Rice Chex: Corn Chex is a direct swap and equally crunchy. Crispix also works. Skip wheat-based cereals — they soften faster and lose their texture within a few hours.
Common problems and fixes
- Coating is wet and clumpy, not dry and powdery: The cereal was too warm when it went into the bag. Spread it back out on the sheet pan, let it cool another 5 minutes, then re-shake with a fresh handful of powdered sugar.
- Cereal is getting crushed during shaking: The bag is too full or you’re shaking too hard. Use a 2-gallon bag and work in two batches if needed — a gentle toss is all it takes.
- Chocolate coating is thick and uneven: The chocolate-peanut butter mixture cooled too much before you added the cereal. Next time, pour the cereal into the warm bowl immediately. If it’s already happened, a 10-second microwave blast on the chocolate (before adding cereal) brings it back.
- Powdered sugar disappears after sitting: This happens when the coating is still slightly warm and the sugar absorbs in. Add a second round of powdered sugar once the batch is fully cooled — skip the garnish of extra sugar on top though, it’s not worth the extra dish.
- Mix tastes flat: A pinch of salt in the chocolate mixture makes a real difference. If yours tastes one-dimensional, a light sprinkle of flaky salt over the finished batch fixes it without starting over.
Leftovers and make-ahead
Muddy Buddies keep well at room temperature in an airtight container for up to 5 days — no refrigeration needed, and actually better without it, since the fridge introduces moisture that softens the cereal. If you want to make them ahead, the full batch can be done the night before with no quality loss; the coating firms up nicely as it sits. For longer storage, freeze in a zip-top bag for up to 6 weeks. Let them thaw at room temperature for 20–30 minutes before serving — they come back to full crunch without any reheating.
Puppy Chow Chex Mix (Muddy Buddies)
Equipment
- Large mixing bowl (at least 6–7 quarts)
- Microwave-safe bowl (1.5–2 quarts) or small saucepan/double boiler
- Rubber spatula
- Rimmed sheet pan
- Parchment paper
- 2-gallon zip-top bag or large lidded container
- Measuring cups and spoons
- Instant-read thermometer (optional, for chocolate temperature)
- Fine-mesh strainer (optional, to sift powdered sugar)
Ingredients
Puppy Chow Chex Mix
- 9 cups Rice Chex cereal Fresh and crisp; Rice Chex is naturally gluten-free. Corn Chex also works.
- 1 cup Semisweet chocolate chips About 6 oz; choose 50–60% cacao for best balance (e.g., Guittard, Ghirardelli).
- ½ cup Creamy peanut butter No-stir style (Jif, Skippy) melts most smoothly; if natural, stir until perfectly homogenous.
- 4 tablespoons Unsalted butter, cut into cubes About 1/2 stick (2 oz).
- 1 teaspoon Pure vanilla extract Adds aroma and rounds sweetness.
- ¼ teaspoon Kosher salt Enhances chocolate and peanut flavors.
- 1 ½ cups Powdered sugar (confectioners’ sugar) Sift if clumpy; Domino recommended for consistent texture.
- ½ cup Powdered sugar (extra, as needed) Use only if the coating still looks shiny after first toss.
- 1 cup Mini pretzels (optional, for serving) Stir in after the mixture is fully cooled.
- ¾ cup Mini M&M’s or chocolate candies (optional, for serving) Add after cooling to prevent color bleed.
Instructions
- Prep the pan and cereal (2 minutes): Line a rimmed sheet pan with parchment. Add 9 cups Rice Chex to a large mixing bowl so it’s ready for coating.
- Melt chocolate, peanut butter, and butter (3–4 minutes): In a microwave-safe bowl, combine chocolate chips, peanut butter, and butter. Microwave at 50% power for 60 seconds, stir, then continue in 20–30 second bursts until smooth and glossy, about 120–130°F (49–54°C). Do not exceed 130°F (54°C) to keep the chocolate silky. Stovetop option: melt gently over a double boiler with barely simmering water (~185°F / 85°C) beneath; keep the bowl bottom off the water and the chocolate below 130°F (54°C).
- Flavor the base (30 seconds): Stir in vanilla and kosher salt until fully incorporated. The mixture should smell nutty and aromatic with a light fudge-like sheen.
- Coat the cereal (1–2 minutes): Pour the warm chocolate mixture over the cereal. Using a rubber spatula, fold gently from the bottom up to avoid crushing. Continue until every piece looks evenly glossy with no dry pockets.
- Sugar toss (2–3 minutes): Transfer coated cereal to a 2-gallon zip-top bag. Add 1 1/2 cups powdered sugar, seal with most air pressed out, and shake vigorously until every piece is matte and evenly dusted. If areas still look shiny, add up to 1/2 cup more powdered sugar and shake again.
- Set the coating (5 minutes): Spread onto the lined sheet pan and let stand at room temperature 68–72°F (20–22°C) until the coating feels dry to the touch. In humid kitchens, chill for 5 minutes to speed setting—avoid longer chilling to prevent condensation.
- Optional add-ins and serve (1–2 minutes): Once fully cooled and dry, fold in mini pretzels and mini M&M’s if using. Serve immediately or store airtight up to 1 week (or freeze up to 1 month).
Notes
Jen’s Tips
- Sharper chocolate flavor: Use 60% cacao chips or mix half milk chocolate with half dark for a balanced sweetness.
- Nut-free: Swap peanut butter for sunflower seed butter or cookie butter (Biscoff) and use allergy-friendly chocolate.
- Vegan: Use dairy-free chocolate and plant-based butter.
- Gluten-free: Stick with Rice Chex and confirm add-ins are certified gluten-free.
- Clump control: If large clusters form, break them gently while tossing in sugar to keep a light, even coat.
- Extra-crisp finish: After setting, sift a little extra powdered sugar over the top for a snowy look that photographs beautifully.
- Flavor twists: Add 1/2 teaspoon ground cinnamon to the powdered sugar for a churro vibe, or 1 tablespoon cocoa powder for double-chocolate.
Serving Suggestions
- Heap into a parchment-lined bowl for height and drama; finish with a light snowfall of powdered sugar and a few colorful candies for contrast.
- Pair with cold milk, hot cocoa, or coffee. Aromas should be nutty-chocolatey with a hint of vanilla; the texture crisp outside and tender within.
Culinary Context
Born from American home kitchens and popularized by Chex in the late 20th century, this no-bake treat became a Midwestern potluck staple for its speed and universal appeal. Despite the nickname, it’s strictly a human dessert.Optional Advanced Instructions
- Make-ahead: Measure cereal and line the pan up to 1 day ahead; keep cereal sealed for maximum crunch.
- Scaling: Recipe doubles cleanly; melt in two batches to keep chocolate below 130°F (54°C) for best texture.
- Cleaner coating: Sift powdered sugar before use to avoid speckles and ensure a delicate finish.

Frequently asked questions
Can I use a different nut butter instead of peanut butter?
Yes — almond butter and cashew butter both work well and behave similarly to peanut butter in this recipe. Sunflower seed butter is a good nut-free option, though it can give the coating a slightly greenish tint over time due to a reaction with the powdered sugar, which is harmless but worth knowing.
Do I need a candy thermometer or instant-read thermometer?
No. The thermometer is listed as optional and you genuinely don’t need it if you melt the chocolate slowly in short microwave bursts and stop as soon as it’s smooth. The main thing to avoid is scorching, and low-and-slow melting takes care of that without any equipment.
Can I double the batch for a party?
Yes, and it scales easily. The only adjustment is that you’ll need to work in two or three shaking batches — a 2-gallon bag can’t handle a doubled recipe at once without crushing the cereal. Melt the chocolate in one go, coat all the cereal, then divide it between bags for the powdered sugar step.
