Protein Muddy Buddies (Gluten-Free + Dairy-Free)
These protein Muddy Buddies are the classic chocolate-peanut-butter snack with 16 grams of protein per cup — no baking, one bowl, about 15 minutes start to finish. Gluten-free, dairy-free, and easy enough that the kids can make them without me.
I started making them because protein bars are expensive, and my boys took one bite of half the ones I bought and handed them right back. I wanted a bar’s worth of protein in a form they’d actually finish. Not choke down — finish, and come back for more.
All my teen boys tried these and said the same thing: “Wow, Mom, this is actually good.” Even one of my pickiest.
Fair warning — these are not diet food, and they’re not trying to be. They’re built to fuel growing kids and teen athletes, the ones who empty the pantry by 4 pm. (If that’s your house too, I keep a running list of gluten-free, dairy-free snacks that actually hold up.)
Why You’ll Love This Recipe
- As much protein as a protein bar (16g per cup!)— but in a snack kids actually reach for, not the one that sits in the pantry.
- Gluten-free and dairy-free — made with Rice Chex and dairy-free chocolate, no separate batch needed.
- Real fuel for teen athletes — perfect for before or after sports when they need to load up on protein and calories.
- Lunchbox-friendly — as long as your school allows peanuts (more on that below).
- So easy the kids can make it — no baking, no special equipment, one bowl and a zip-top bag.
- Not just for kids — adults trying to get more protein in will happily eat these too.
- Egg-free and nut-free-adaptable — see the swaps in the FAQ.
Ingredients
Here’s what goes in and why. Quantities are in the recipe card below.
- Rice Chex — the gluten-free base. Rice Chex is naturally gluten-free (double-check the box, but the rice version is the one you want). They stay crunchy and hold the coating well.
- Dairy-free mini chocolate chips — I use Enjoy Life semi-sweet minis. They melt smoothly and are free of the top allergens, so they’re an easy dairy-free pick. They are easy to find at Walmart, Target, and Amazon.
- Natural creamy peanut butter — I use Skippy Natural. It melts into the chocolate and gives that classic Muddy Buddy flavor.
- Refined coconut oil or vegan butter — helps the chocolate coating go on smooth and set up firm. I prefer vegan stick butter like this Country Crock one I love from Walmart. But, if you use coconut oil, use refined so there’s no coconut taste.
- Vanilla and salt — small amounts, big difference. The salt keeps it from tasting flat-sweet.
- Unflavored collagen peptides — this is one of the two things that turns dessert Muddy Buddies into protein Muddy Buddies. I use unflavored collagen because it blends right into the hot chocolate mixture and disappears — no grit, no weird taste. I buy Vital Proteins at Costco when it’s on sale; it’s one of the most affordable, allergen-friendly protein powders I’ve found. It’s the same trick I use in my peanut butter oatmeal protein breakfast cookies.
- Powdered sugar — the classic outer coating. It’s what makes them Muddy Buddies.
- Peanut butter powder (PBfit No Sugar Added) — the second protein booster, tossed into the powdered sugar coating. If you haven’t used it, PBfit doesn’t have much flavor on its own, and that’s exactly why it works here — it adds protein to the coating without making the flavor weird. I get it at Walmart or on Amazon.
Packing these for school lunch? They’d fit right into my whole food lunch box guide — just check your school’s nut policy first.
How to Make It
- Add the Chex to a big bowl and set it aside. You want plenty of room to fold and toss later, so go bigger than you think.
- Melt the chocolate, peanut butter, and vegan butter together. Microwave in 30-second bursts, stirring between each, until it’s smooth — about a minute to a minute and a half total. Short bursts matter here; chocolate scorches fast if you walk away.
- Whisk in the vanilla, salt, and collagen while it’s still warm. This is the step that makes or breaks the protein part. Add the collagen right away, while the mixture is hot, and whisk until no lumps remain. It dissolves clean and disappears when it’s warm — let the mixture cool first and it won’t blend in as nicely.
- Pour the coating over the Chex and fold gently. Take your time and fold until every piece is coated. Gentle is the word — you don’t want a bowl of cereal dust.
- Whisk the powdered sugar and PBfit together, then coat. Combine the two so the protein powder is evenly mixed in, add it to the cereal, and toss in the bowl — or dump everything into a big zip-top bag and shake. The bag is the easy-cleanup, kid-friendly way to do it.
- Spread on a parchment-lined sheet to set, about 15 minutes. Then store airtight.
That’s it. No oven, no chilling overnight, no fuss.
Substitutions
Here’s the quick rundown of what you can swap and what to expect. I’ve only tested the version as written, so treat any swap as a solid starting point.
- Rice Chex → another gluten-free cereal: Corn Chex or a plain gluten-free rice square works the same way. Stick with something sturdy — flakes turn to dust as soon as you start folding.
- Peanut butter → sunflower seed butter: Swaps in for the melted coating and sets up the same. (Nut allergy — see the FAQ below.)
- Vegan butter → refined coconut oil: Both make the coating go on smooth and set firm. Use refined so there’s no coconut taste.
- Collagen peptides → another unflavored protein powder: Unflavored is the requirement, not the type — flavored and vanilla versions throw the taste off. I use collagen because it disappears into the hot chocolate with no grit; I haven’t tested whey or plant-based powders here, and whey isn’t dairy-free.
- PBfit → more powdered sugar: Straight powdered sugar coats them just fine and tastes classic. You lose that part of the protein, so the total lands lower.
- Powdered sugar: No swap. It’s what makes them Muddy Buddies, and it’s what the coating clings to.
- Dairy-free chocolate chips: Any dairy-free semi-sweet chip works. I keep Enjoy Life minis on hand because they’re free of the top allergens.
How to Store Them
Store them airtight at room temperature. They keep for about a week — if they last that long around here, which they don’t.
Two things worth knowing. Let them set the full 15 minutes on the parchment before anything goes in a container, or the coating smears and you lose the powdery outside. And if you’d rather the coating be firmer, keep them in the fridge — it sets up harder in there.
If you want another make-ahead protein snack that keeps like this, my no-bake monster protein balls live in our fridge on repeat.
FAQ
How much protein is in these? 16 grams per cup – a lot for a snack. The protein comes from two places — collagen peptides whisked into the chocolate coating, and peanut butter powder mixed into the powdered sugar. Between the two, a serving lands right around what you’d get from a protein bar. Exact macros are in the recipe card, calculated from these specific brands.
Are these actually a health food / low calorie? No, and that’s on purpose. These are meant to fuel growing kids and teen athletes who need calories AND protein — not to be a diet snack. If you’re feeding hungry, active bodies, that’s a feature. If you want something lighter, this isn’t the recipe for that.
Can I make these nut-free? The peanut butter is the sticking point. For the melted coating, sunflower seed butter swaps in well for the peanut butter. For the coating powder, you can leave out the PBfit and just use powdered sugar (you’ll lose that bit of protein) — a nut-free seed-based protein powder can work, but taste as you go since flavors vary. Always double-check every label if you’re cooking around a real allergy.
My collagen clumped — what happened? It usually means the mixture cooled too much before the collagen went in. Add it while everything is still warm and whisk right away; it dissolves clean when it’s hot. If you do get lumps, a few more seconds in the microwave and a good whisk will smooth it back out.
Can the kids make these themselves? Yes, and that’s half the point. Aside from the quick microwave step, this is a fold-and-shake recipe. It’s a great one to hand off to a kid who wants to “cook.”

Protein Muddy Buddies
Ingredients
- 9 cups Rice Chex
- 3/4 cup dairy-free chocolate chips I love Enjoy Life mini chips
- 2/3 cup peanut butter thick and creamy, not the kind you have to stir
- 2 tablespoons vegan butter or coconut oil
- 1 teaspoon vanilla
- 1/4 teaspoon salt
- 1/2 cup + 2 tablespoons unflavored collagen powder I love and use Vital Protein
Dry Coating
- 1 cup powdered sugar
- 1/2 cup PBfit No Sugar Added peanut butter powder
Instructions
- Add the Chex to a big bowl and set it aside. You want plenty of room to fold and toss later, so go bigger than you think.
- Melt the chocolate, peanut butter, and vegan butter together. Microwave in 30-second bursts, stirring between each, until it's smooth — about a minute to a minute and a half total. Short bursts matter here; chocolate scorches fast if you walk away.

Add the collagen right away, while the mixture is hot, and whisk until no lumps remain. (It dissolves cleanly and disappears when it's warm — let the mixture cool first, and it won't blend in as nicely). The mixure will thicken, but still be pourable.
- Pour the coating over the Chex and fold gently. Take your time and fold until every piece is coated. Gentle is the word — you don't want a bowl of cereal dust.
- Whisk the powdered sugar and PBfit together, then coat. Combine the two so the protein powder is evenly mixed in, add it to the cereal, and toss in the bowl — or dump everything into a big zip-top bag and shake. The bag is the easy-cleanup, kid-friendly way to do it.

Nutrition
Do you think I could substitute with a different protein powder? I have vanilla and chocolate paleo protein and have subbed it for the protein muffins with good results. Might give it a try this weekend
Hi! Thanks for wanting to make these. This note is in the recipe for that question:
CAN I USE A DIFFERENT PROTEIN POWDER? Possibly, but it needs to be one that dissolves in hot liquids. Double-check yours does, or it will result in a clumpy, non-pourable mess once you add it to the melted chocolate or leave a gritty texture.
