Made with Rice Chex, creamy peanut butter, melted chocolate, mini marshmallows, and a dusting of powdered sugar, they’re quick to prepare and much easier to share than the traditional bag-shaken version.

Ingredients
Hosting Shortcut!
These are entirely no-bake. Melt the chocolate, peanut butter, and butter, fold in the cereal, press into a pan, and chill until firm. They’re ideal for summer gatherings, last-minute desserts, or baking with kids.
Ingredient Notes
- Rice Chex cereal – Rice Chex is naturally gluten-free, but always check the box to ensure it’s labeled gluten-free if you’re serving someone with celiac disease.
- Semi-sweet chocolate chips – Semi-sweet gives the classic flavor; swap for milk or dark chocolate to suit your taste.
- Creamy peanut butter – Use standard creamy peanut butter for the best texture. Natural peanut butters that separate can make the bars slightly greasier.
- Mini marshmallows – Adding marshmallows gives the bars a slightly chewy, cohesive texture that slices cleanly without being sticky.
- Powdered sugar – Dust lightly for the classic look, or dip each square individually into powdered sugar for a heavier coating.
How to Make Muddy Buddy Bars
Overview: Melt chocolate, peanut butter, and butter; stir in marshmallows until smooth; fold into Rice Chex; press into a lined pan; dust with powdered sugar; chill until firm. Below are the full ingredient amounts and step-by-step instructions in the recipe card.
For exact measurements, full method, printable recipe, and nutrition information, see the recipe card below.
Expert Tips
- Line the pan with parchment and leave an overhang. This makes it easy to lift the bars out in one piece for neat slicing.
- Fold gently. Use a silicone spatula and a folding motion to coat the cereal without crushing it.
- Cut to your preferred size. These bars hold their shape well—slice large squares for a hearty treat or smaller bites for a snack platter.
Storage instructions
Refrigerator
Store bars in an airtight container in the refrigerator for up to one week. They’ll also keep at room temperature for a few days, but chilling firms them up and improves slicing.
Freezer
Freeze individual bars wrapped tightly or layered between parchment in an airtight bag for up to one month. Thaw at room temperature 15–20 minutes before serving.
Make-Ahead Tip
These no-bake bars are ideal to prepare a day or two ahead. They slice cleaner when fully chilled, making them great for hosting or gifting.
Serving suggestions
These bars are excellent on dessert trays, snack boards, or packaged as edible gifts. Serve slightly chilled for a firmer bite, or enjoy at room temperature—both work well for parties, potlucks, and holiday tins.
Style tip: Dust a fresh layer of powdered sugar right before serving for the classic puppy chow appearance.

Gluten-Free Puppy Chow Bars
Ingredients
- 4 cups Rice Chex cereal (about 120g)
- ¼ cup unsalted butter (½ stick, 57g)
- 1 cup semi-sweet chocolate chips (170g)
- ¾ cup creamy peanut butter (192g)
- 5 oz mini marshmallows (140g)
- ¼ cup powdered sugar (30g), for dusting
Use a gentle folding motion to keep the cereal from breaking. Instruction photos are available above.
Instructions
- Place 4 cups Rice Chex cereal into a large mixing bowl and set aside.
- In a microwave-safe bowl, combine ¼ cup unsalted butter, 1 cup semi-sweet chocolate chips, and ¾ cup creamy peanut butter. Microwave at 50% power in 30-second intervals for 1½–2 minutes, stirring between intervals, until smooth.
- Add 5 oz mini marshmallows to the warm mixture and microwave another 30 seconds. Stir until fully melted and the mixture is thick and glossy.
- Pour the chocolate-peanut butter mixture over the Rice Chex. Gently fold until the cereal is evenly coated, taking care not to crush it.
- Transfer the coated cereal into an 8×8-inch baking dish lined with parchment paper, leaving an overhang. Press the mixture into an even layer using a greased spatula or lightly greased hands.
- Dust the top with ¼ cup powdered sugar.
- Refrigerate at least 1 hour, or until firm. Use the parchment overhang to lift the bars from the pan, slice into squares or rectangles, and serve. Optionally toss pieces in extra powdered sugar just before serving.
