Keto Puppy Chow — Sugar-Free Muddy Buddies with Catalina Crunch
/Puppy chow — also known as muddy buddies depending on where you grew up — is one of those snacks that disappears in about four minutes flat at any party. Chocolate, peanut butter, and powdered sugar coating crunchy little cereal pieces. It's genuinely one of the best snack combinations ever invented.
The problem is that traditional puppy chow is made with Chex cereal, regular chocolate chips, and a full cup of powdered sugar. It's delicious and it will absolutely spike your blood sugar into the stratosphere. Which is fine if that's your thing — but if you're eating low carb or keto and you have a serious sweet tooth (same), you need a version that actually works.
This keto puppy chow uses Catalina Crunch chocolate cereal instead of Chex, Lily's sugar-free dark chocolate chips, no-sugar-added peanut butter, and Lakanto powdered monk fruit sweetener for the coating. It tastes like the real thing. My non-keto friends and family eat this without knowing it's sugar-free, and that is always the benchmark for whether a keto dessert actually passes.
6.4g net carbs per 1/2 cup serving. Yield: 9 servings. Takes 35 minutes including the fridge time for the chocolate to set.

1 cup Lakanto Powdered Monk Fruit Sweetener — divided (3/4 cup first, 1/4 cup after chilling)
1 bag Catalina Crunch Chocolate Cereal — see the full section below on why this works
What Is Catalina Crunch — and Why It's the Perfect Keto Chex Substitute
This is the question everyone has when they see this recipe for the first time, so let me explain it properly.
Traditional puppy chow is made with Chex cereal — specifically the Rice Chex or Corn Chex varieties, which are light, airy, and crunchy. The problem is Chex is a refined grain cereal with zero fiber and around 25g of carbs per cup. Not keto.
Catalina Crunch is a low-carb, high-protein, grain-free cereal made from a blend of pea protein, tapioca, chicory root fiber, and other plant-based ingredients. The chocolate variety has:
11g protein per serving
5g net carbs per serving
9g fiber per serving
No added sugar
A crunchy texture that holds up in the chocolate peanut butter coating without going soggy
The chocolate flavor of the Catalina Crunch also adds another layer of chocolate to the muddy buddies, which only makes the whole thing better. It's available on Amazon, at Target, Whole Foods, and most Sprouts locations. The chocolate variety is the one to use for this recipe — the Mint Chocolate and Dark Chocolate varieties also work great if you want to mix it up.
Can I use a different cereal?
Technically yes, but Catalina Crunch is the best option for this specific recipe. Magic Spoon cereal works as a substitute. Keto granola can also work but changes the texture significantly — the clusters don't coat as evenly. If you can't find Catalina Crunch locally, it's on Amazon with Prime shipping.
The Best Peanut Butter for Keto Muddy Buddies
Most peanut butter at the grocery store has added sugar, palm oil, or hydrogenated vegetable oils — none of which belong in a clean low carb recipe you're eating regularly. Here's what to look for:
Ingredients list: should be peanuts and salt, nothing else. Two ingredients maximum.
No palm oil: palm oil is commonly added to prevent separation but it's an inflammatory fat. Skip it.
No added sugar: this one seems obvious for a keto recipe but it's in more peanut butters than you'd think — check the label.
This is the peanut butter I use .
Almond butter or sunflower seed butter work as substitutes if you're avoiding peanuts — both coat the cereal well and pair nicely with the chocolate.
How to Make Keto Puppy Chow — Step by Step
Melt the chocolate mixture. Add the Lily's dark chocolate chips, softened butter, and no-sugar-added peanut butter to a medium microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until completely smooth and melted — usually 60 to 90 seconds total. Alternatively, use a double boiler on the stovetop: place the bowl over a pot of barely simmering water and stir until melted. Do not let the bowl touch the water.
Coat the cereal. Pour the entire bag of Catalina Crunch chocolate cereal into a large bowl. Pour the chocolate peanut butter mixture over the cereal and gently fold and stir until every piece is evenly coated. Work quickly — the chocolate starts to set as it cools.
Add the first coat of sweetener. Transfer the coated cereal to a gallon zip-lock bag. Add 3/4 cup of the Lakanto Powdered Monk Fruit Sweetener. Seal the bag and shake well until every piece is coated in the powdered sweetener. Don't rush this step — the more evenly you coat it now, the better the final texture.
Spread and chill. Pour the coated cereal onto a parchment-lined baking sheet and spread into an even layer. Break up any large clusters with your fingers or a fork. Refrigerate for 20 to 30 minutes until the chocolate is completely set and the coating is dry to the touch.
Final coating. Once set, transfer back to the zip-lock bag and toss with the remaining 1/4 cup of Lakanto Powdered Monk Fruit Sweetener. This second coating is what gives you that classic thick white powdered sugar look. Serve immediately or store in an airtight container.
Pro tip — room temperature matters- Make sure your butter is genuinely softened to room temperature before mixing — not melted, softened. Cold butter will cause the chocolate mixture to seize and clump instead of coating smoothly. If your kitchen is cold, give the butter an extra 30 minutes on the counter, or microwave it for just 5-8
Troubleshooting — Why Is My Keto Puppy Chow Sticky?
This is the most common issue with puppy chow in general — keto or regular. Here's why it happens and how to fix it:
The coating is wet or sticky
Most likely cause: the chocolate didn't set fully before you added the second coat of sweetener, or the sweetener absorbed too much moisture from the chocolate. Fix: spread back onto the parchment-lined sheet and refrigerate for another 15 minutes. Then re-toss with an additional 2-3 tablespoons of Lakanto powdered sweetener.
The pieces are clumping together
Most likely cause: they were too warm when transferred to the zip-lock bag, causing the chocolate to stick before the sweetener could coat them. Fix: break up gently with your hands and refrigerate in a single layer on the baking sheet until fully set.
The sweetener doesn't look white enough
Most likely cause: not enough sweetener on the second coat, or the first coat didn't dry enough before the second was added. Fix: toss with more Lakanto powdered sweetener a tablespoon at a time until you get the look you want. There's no such thing as too much powdered sweetener on muddy buddies.
The monk fruit sweetener tastes slightly different from powdered sugar
This is normal. Monk fruit sweetener has a slightly cleaner, less sweet aftertaste than powdered sugar to some people. Most people don't notice once it's combined with the chocolate and peanut butter. If the taste bothers you, try Swerve Confectioners as an alternative — it's erythritol-based and has a profile closer to powdered sugar for some palates.
How to Store Keto Puppy Chow
Room temperature
Store in an airtight container or zip-lock bag at room temperature for up to 3 days. The coating stays dry and the cereal stays crunchy in a cool, dry location. Avoid humidity — moisture is the enemy of the powdered coating.
Refrigerator
Refrigerate in an airtight container for up to 2 weeks. The texture holds well in the fridge and the chocolate stays set. Take out 10-15 minutes before eating if you prefer it at room temperature — it's good cold too.
Freezer
Freeze in a sealed freezer bag for up to 3 months. Let thaw at room temperature for 15-20 minutes before eating. The coating may need a quick toss with a little extra Lakanto powdered sweetener after thawing if it looks damp.
Meal prep
This recipe makes 9 servings and stores well, which makes it one of the best keto meal prep snacks to have on hand. Make a batch on Sunday and portion into individual snack bags or small containers so you can grab one throughout the week without going back to the big batch every time.
Serving Ideas — Parties, Holidays, and Gifting
Puppy chow is one of those universally loved snacks that works for every occasion. Here's how I use this keto version:
Holiday parties
Keto puppy chow is perfect for Thanksgiving, Christmas, and New Year's spreads. Non-keto guests eat it enthusiastically without knowing it's sugar-free — I've tested this repeatedly. Serve it in a large bowl with a small scoop, or portion it into individual treat bags tied with ribbon for a party favor or hostess gift.
Super Bowl and game day
This is the ideal game day snack — shareable, no plates or utensils needed, naturally gluten-free so it works for most dietary restrictions, and it can be made two days ahead. Make a double batch and put it in a big bowl. It won't last through halftime.
Holiday gifting
Portion the puppy chow into clear treat bags or small mason jars, tie with a ribbon, and add a tag that says 'sugar-free' — people with dietary restrictions are genuinely touched when someone thinks about them at the holidays. A batch makes 9 generous servings which divides nicely into 4-5 gift portions.
Everyday snacking
Portion into 1/2 cup servings in small snack containers at the start of the week. When you want something sweet after dinner, you've got a ready-made answer that isn't a blood sugar spike.
Variations and Swaps
Mint chocolate muddy buddies — use Catalina Crunch Mint Chocolate cereal and add 1/4 teaspoon of peppermint extract to the chocolate mixture. Perfect for Christmas.
Dark chocolate almond butter version — substitute almond butter for peanut butter for a slightly more sophisticated flavor.
Sunflower seed butter version — makes it peanut-free and school-safe. The flavor is slightly different but it works beautifully.
White chocolate drizzle — melt a small amount of Lily's white chocolate chips and drizzle over the set puppy chow before the final powdered sweetener coat.
Add sea salt — a pinch of flaky sea salt on top of the finished puppy chow elevates the chocolate peanut butter combination significantly.
Keto trail mix version — add a handful of mixed nuts, unsweetened coconut flakes, and Lily's chocolate chips to the finished batch for a more textured snack mix.
Frequently Asked Questions
What's the difference between puppy chow and muddy buddies?
Nothing — they're the exact same recipe with two different names. 'Puppy chow' is more commonly used in the Midwest, 'muddy buddies' is the name Chex uses on their official recipe. Same chocolate-peanut butter-powdered sugar coated cereal either way.
Is Catalina Crunch actually keto?
Yes. Catalina Crunch is grain-free, low in net carbs (5g net carbs per serving), and has 11g of protein per serving. It uses a blend of pea protein, tapioca, and plant fiber. It's widely available and one of the most popular keto cereal options on the market. The chocolate variety is the one to use for this recipe.
Can I use a different low carb cereal?
You can use Magic Spoon cereal as a substitute — it's another widely available keto cereal that coats well. Keto granola works in a pinch but the texture is different. Regular Chex is not keto-friendly (25g carbs per cup) so that's not a substitute for the keto version of this recipe.
Is Lakanto monk fruit sweetener a 1:1 substitute for powdered sugar?
Yes — Lakanto Powdered is a direct 1:1 substitute for powdered sugar in recipes. It has zero net carbs, zero glycemic index, and behaves almost identically to powdered sugar in terms of coating and texture. Some people notice a slight cooling sensation that erythritol-based sweeteners can cause — if that bothers you, Swerve Confectioners is another excellent option.
How many net carbs are in keto puppy chow?
6.4g net carbs per serving (approximately 1/2 cup). The recipe makes 9 servings. The carbs come primarily from the Catalina Crunch cereal and the trace carbs in the peanut butter and chocolate. Lily's chips and Lakanto sweetener contribute zero net carbs.
Can I make this dairy-free?
Yes — substitute the Kerrygold butter with refined coconut oil (same amount). The chocolate mixture will be slightly thinner but will still coat the cereal and set properly in the fridge. Make sure your chocolate chips are also dairy-free — Lily's dark chocolate chips are made in a facility that processes dairy, so check the label if you have a severe dairy allergy.
Why does my puppy chow get sticky?
The most common causes: the chocolate didn't set fully before adding the powdered sweetener, or there was moisture in the coating. Fix: spread back on parchment and refrigerate another 15 minutes, then re-toss with additional powdered sweetener. See the full troubleshooting section above.
