These Puppy Chow Bars will definitely not go to the dogs after you see how easy and delicious a treat they are. Of course, I want to stress that these are for humans only. By adding marshmallows to the mix, you will have a panful of this delicious and popular snack. Simply add some Golden Grahams to your ingredients to try my S’mores Puppy Chow.

When I think of Puppy Chow, I think of being covered in confectioners sugar, or at least, leaving a few sprinkles of it on my face! This recipe is very similar to my Puppy Chow recipe, except I added marshmallows and did not use vanilla.

Ingredients & Substitutions

With a few yummy and basic ingredients, you will have a pan of Puppy Chow Bars that you can bring anywhere, from your camping trip to a holiday party.

Chocolate: Semi-Sweet was the chocolate of choice for this recipe.  You could use milk chocolate too, but that might be too sweet and not have much depth of flavor.

Peanut Butter:  The great debate, creamy versus chunky.  When it comes to puppy chow, creamy peanut butter is the way to go. If you can’t have peanut butter, tree nut butter (such as almond, cashew, walnut, and hazelnut) are substitutes for peanut butter. I have not tested them.

Rice Cereal:  I use Rice Chex, but any waffle-shaped cereal will do.  This is just the vessel that holds all of the chocolatey goodness together. You can also use Golden Grahams!

Mini Marshmallows: These will help hold up your bars to make them easy to eat.

Confectioners Sugar: To coat each bar or to sprinkle on top is up to you! I chose to sprinkle the powdered sugar on top for this recipe, but keep reading to see how my mom used to do it!

Ingredients for Puppy Chow Bars

Melt and Mix

Place the chocolate chips, peanut butter, and butter in a medium-sized microwave-safe bowl. Microwave on high in 30-second intervals and stir after each session. (It’s usually fully melted in about a minute and a half.)

Here is where you add the marshmallows. Stir them in before you put the mixture back in the microwave. Again, microwave in 30-second intervals to make sure the marshmallows puff and melt.

Pour the cereal into a large mixing bowl. (Bigger than you think you need, this gets messy.) Generously coat the cereal with the marshmallow mixture by pouring it over the cereal and stirring until everything is ooey and gooey!

How Ooey Gooey Should They Be?

This is where you will determine just how much cereal you want to use. If you want a bar with every single piece of cereal coated in the chocolate peanut butter mixture, start by only adding 5 cups of cereal. You can always add more, but you can’t take cereal out, so take your time and make sure they are the exact consistency you want.

Chilling Puppy Chow Bars

Once you have your desired ooey gooey-ness, put the mixture into a 9×13 inch greased baking pan and press down firmly. Put the pan in the refrigerator to let the bars chill for 10-15 minutes. (I know, it’s hard to wait…) After the Puppy Chow Bars are chilled, take them out of the refrigerator and sprinkle them with powdered sugar. Cut them into small bars and share them.

Sugar Coated Puppy Chow Bars

As you can see by the images and recipe directions, I opted for a sprinkling of confectioners sugar. Some folks cut up the bars and toss them in a paper bag, (yes, really) add confectioners sugar, and shake shake shake. This means that every single exposed surface was generously coated in confectioners sugar. I opted not to do that for a couple of reasons… it’s messy and it’s not necessary for flavor. But you still can!

How to Store Puppy Chow Bars

These are best covered at room temperature for 2-3 days, but you can certainly refrigerate for up to 7 days.

  2. How can people really be this dumb not to know this is a human recipe. Really people. No one has and common sense anymore. This sounds yummy.

  3. Delicious! My husband and I loved these! I did add a splash of vanilla extract to the chocolate/PB mixture before adding the marshmallows. I also mixed a little powdered sugar in before pressing them into the pan as well as PS on top! Thanks so much!

  4. This is almost same as muddy buddies , ingredients are the same & mostly same as this recipe except it is not made as a loaf cake it is made as chex mix and coated in powdered sugar , shake coated cereal mix in powdered sugar.
