These Puppy Chow Topped Peanut Butter Brownies are made with fudge brownie filled with a layer of creamy peanut butter and topped with puppy chow (aka muddy buddies).
Quick Tips
- Bake these for at least 30 minutes or until a toothpick comes out without any brownie batter on it (you will see the peanut butter filling on the toothpick). The filling causes these to need a longer bake time!
- Don’t add the chocolate ganache and puppy chow topping until you are ready to eat these! The puppy chow will get stale in 1-2 days after it’s added to the brownies
- Using the pan that you will bake the brownies in, first create your peanut butter filling by melting and spreading the peanut butter over the bottom of the lined pan. Then freeze it for 20-30 minutes so that you can add it to the center of your brownie batter
Equipment
- 8×8 baking pan (metal pan is recommended)
- Parchment paper
- Hand or stand mixer
- 2-3 mixing bowls
- Silicone spatula
- Measuring cups and spoons
- Food scale (optional – for weighing the peanut butter)
Ingredient Notes
- Unsalted butter: salted butter is OK too, but then remove added salt
- Granulated sugar
- Unsweetened cocoa powder
- Chocolate chips: chopped baking chocolate is OK too, semi-sweet chocolate is recommended, but milk or sweetened dark chocolate will work too
- Eggs
- Vanilla extract
- Creamy peanut butter: do NOT use natural peanut butter (it’s too runny). I prefer Jif brand
- Chex cereal: corn or rice Chex works, or any rice square ceral
- Heavy cream
- Powdered sugar

How to make Puppy Chow Topped Peanut Butter Brownies
These puppy chow topped peanut butter brownies can be broken down into three steps.
- Prepare the peanut butter filling
- Prep and bake the brownies
- Top the brownies
How to prepare the peanut butter filling
Line an 8×8 pan with parchment paper. I recommend using a metal (not a glass) pan as the brownies will bake more evenly in these.
Heat up the creamy peanut butter until it is pour-able but not too hot. Do NOT use natural peanut butter for the filling as it is too runny. I recommend Jif Brand.
Lastly, pour the peanut butter over the lined 8×8 pan and spread it evenly throughout the pan. Freeze it for 20-30 minutes or until the peanut butter has set. Leave the pan in the freezer until you are ready to assemble the brownies.
How to prep and bake the brownies
Preheat the oven to 350 degrees. Use the convection bake setting if you have it.
In a medium-large mixing bowl, add melted butter and granulated sugar. Whisk together (or use a hand or stand mixer) for 1-2 minutes.
Next, add the eggs, vanilla extract, melted chocolate and salt. Mix until combined.
Then add the cocoa powder and flour and mix carefully until fully combined. Scrape down the bowl once complete.
Prepare a new parchment lining for the 8×8 pan, then remove the peanut butter filling from the freezer. The peanut butter will begin to melt again as soon as you remove it from the freezer, so you will need to move quickly on this step.
Remove the parchment and frozen peanut butter from the pan and set aside. Re-line the pan with your new parchment paper and add half of the brownie batter to the pan. Spread it evenly throughout the bottom of the pan.
Add the peanut butter filling over the half of the batter by turning the frozen peanut butter over and adding it on top of the batter. Then peel away the parchment paper.
Add the remaining brownie batter over the top of the peanut butter filling and spread it evenly throughout the pan.
Finally, bake the brownies for 30-40 minutes or until a toothpick comes out with no brownie batter on it (you will see the peanut butter filling on the toothpick, but no batter should appear).
How to top the brownies
You can prepare the chocolate ganache topping and puppy chow while the brownies bake. The chocolate ganache will act as a ‘glue’ for the puppy chow to stick to the brownies.
Remove the brownies from the oven and allow them to cool to room temperature before adding the topping. WAIT TO ADD THE TOPPING UNTIL YOU ARE READY TO EAT THE BROWNIES. The puppy chow gets stale on the brownies after 1-2 days.
To make the chocolate ganache, heat the cream in a small microwave safe bowl for 30-60 seconds, or until almost boiling, then add the chocolate chips and mix until smooth. Set the mixture aside (or store in an airtight container in the fridge) until you are ready to top the brownies.
To make the puppy chow topping, add the butter, peanut butter and chocolate chips to a microwave safe mixing bowl. Melt them in the microwave (60-90 seconds) and mix together until smooth. Then add the Chex over the melted chocolate mixture and fold together lightly until the cereal is completely coated in chocolate.
Lastly, add the powdered sugar and fold it together gently until all of the cereal is coated. Set the puppy chow aside (or store in an airtight container in the fridge) until you are ready to top the brownies.
Once the brownies have cooled to room temperature, pour the warmed chocolate ganache over the brownies and spread it evenly throughout the pan.
Immediately add the puppy chow to the tops of the brownies, sprinkling it evenly throughout the pan. Try to make sure that all of the puppy chow pieces are touching the ganache so that it will stick to the brownies.
Place the brownies in the fridge for 30-60 minutes to allow the chocolate ganache to set. Enjoy at room temperature or chilled.

If you don't plan to eat them right away, simply make the brownies and keep the ganache and puppy chow separate (in airtight containers in the fridge) until you are ready to assemble.
- Once the brownies have cooled to room temperature, pour the warmed chocolate ganache over the brownies and spread it evenly throughout the pan. The ganache acts as a glue for the puppy chow.
