Ingredients You’ll Need
The magic of Puppy Chow Bars comes from a handful of simple, pantry-friendly ingredients that each play a vital role in creating its signature taste, texture, and look. From the crispy crunch of the Rice Chex to the silky smoothness of melted peanut butter and chocolate, every component is essential and easy to find.
- Rice Chex cereal (7 cups): Start with 5 cups and adjust to get the perfect crunchy-to-chewy balance in your bars.
- Semi-sweet chocolate chips (1 cup): Provides rich chocolate flavor and smooth melting quality.
- Creamy peanut butter (1 cup, 258 g): Adds that classic nutty taste and creamy texture to bind the bars.
- Unsalted butter (¼ cup, 57 g): Enhances richness and helps the chocolate and peanut butter mix seamlessly.
- Mini marshmallows (1 bag, 10 ounces): Melts into a gooey binder that also adds sweetness and softness.
- Confectioners’ sugar (¼ cup, 31 g): Lightly dusted on top for a pretty, sweet finish that balances the chocolate.
How to Make Puppy Chow Bars
Step 1: Prep Your Cereal Base
Start by pouring your Rice Chex cereal into a large mixing bowl. This will be the crunchy foundation of your bars, so make sure the bowl is big enough to comfortably mix later on without spilling. Remember, you can start with 5 cups and add more to achieve your desired crunch and chew ratio.
Step 2: Melt the Chocolate, Peanut Butter, and Butter
In a medium microwave-safe bowl, combine the semi-sweet chocolate chips, creamy peanut butter, and butter. Microwave the mixture in 30-second bursts, stirring in between, until everything melts together into a smooth, glossy sauce. This luscious blend is the heart of your Puppy Chow Bars, delivering that dreamy peanut butter and chocolate combo we all crave.
Step 3: Add and Melt Mini Marshmallows
Next, stir in all the mini marshmallows. Return the bowl to the microwave and heat again in 30-second increments, stirring each time, until the marshmallows puff up and melt into the chocolate mixture. The resulting thick, creamy mixture is key to sticking all the crispy cereal pieces together into bars you can cut and hold.
Step 4: Combine Cereal and Marshmallow Mixture
Pour the molten marshmallow-chocolate mixture over your Rice Chex in the big bowl. Use a spatula or large spoon to gently but thoroughly coat every piece of cereal. Taking your time here ensures that each bite of the Puppy Chow Bars has the perfect blend of gooey sweetness and crispiness.
Step 5: Press Into the Pan and Chill
Lightly grease a 9×13 inch baking dish and spread the coated cereal mixture evenly inside. Press down firmly to pack it into a uniform layer—this helps your bars hold together when sliced. Pop the pan into the refrigerator for 10 to 15 minutes to let the bars set and firm up just right.
Step 6: Dust with Confectioners’ Sugar and Serve
Once chilled and firm, remove the bars from the fridge and lightly dust the top with confectioners’ sugar. This final touch adds a delicate sweetness and a lovely, snowy appearance that makes these Puppy Chow Bars feel extra special. Slice into squares and get ready to dive in!
How to Serve Puppy Chow Bars

Garnishes
You can keep it simple with just the touch of confectioners’ sugar, or add a drizzle of melted white or dark chocolate for contrast. Crushed peanuts sprinkled on top give a crunchy, nutty finish that complements the peanut butter beautifully.
Side Dishes
Puppy Chow Bars are sweet and rich, so pairing them with a cup of cold milk or a scoop of vanilla ice cream makes a wonderful balance. For a cozy gathering, hot chocolate or coffee with a splash of cream can elevate your snack time into a special treat.
Creative Ways to Present
Set out Puppy Chow Bars on a festive platter with colorful napkins for easy sharing at parties. For kid-friendly occasions, wrap individual squares in parchment paper tied with a ribbon for cute grab-and-go snacks. You can even layer them between sheets of wax paper in a clear container to show off their gooey texture without mess.
Make Ahead and Storage
Storing Leftovers
Store any leftover Puppy Chow Bars in an airtight container at room temperature for up to 3 days. This keeps the bars chewy yet firm without drying out.
Freezing
You can freeze these bars by wrapping individual squares tightly in plastic wrap and placing them in a freezer bag. They keep well for up to 2 months. When ready to enjoy, thaw at room temperature for about 30 minutes before eating.
Reheating
If you like your Puppy Chow Bars a bit softer and warmer, microwave a single square for 10 to 15 seconds. This gently melts the chocolate and peanut butter back to a pleasantly gooey texture without making the whole bar messy.
FAQs
Can I use crunchy peanut butter instead of creamy?
Yes, you can swap in crunchy peanut butter, which will add a lovely extra crunch within the bars. Just note that the texture will be a bit more varied but still delicious.
Are Puppy Chow Bars gluten-free?
Rice Chex cereal is typically gluten-free, but always double-check the packaging to be sure. If confirmed, these bars make a tasty treat for those avoiding gluten.
Can I substitute mini marshmallows with regular-sized ones?
Absolutely! Just measure out the same total amount but chop the larger marshmallows into smaller pieces so they melt evenly within the mixture.
What if I don’t have confectioners’ sugar? Can I skip it?
The confectioners’ sugar is mainly for dusting and adds a subtle sweetness and pretty finish. If you don’t have it, the bars are still wonderful without—it just won’t have that snowy look.
How can I make these bars nut-free?
To make a nut-free version, swap peanut butter for a seed butter like sunflower seed butter. The flavor will differ but the bars will still hold together nicely.
