I don’t know about you, but in our house we love all things cereal and all things chocolate. So when we get a chance to combine the two, we are in heaven. I guess you could say we’re cuckoo for Cocoa Puffs cereal bars.

How to Make Cocoa Puffs Cereal Bars
How can you not like Cocoa Puffs? The chocolaty puffs of sweetened corn, and when you’re done eating them, you have a whole bowl of chocolate milk. So, naturally, we decided making Cocoa Puffs cereal bars was a great idea. And we think you’ll agree.
Cocoa Puffs cereal bars are super easy to make. With just three ingredients you’ll be fine, especially if you’ve made our Lucky Charms cereal bars, Trix cereal bars, or Cookie Crisp cereal bars.
Let’s get to the recipe!

Step One
Put your butter in a large stock pot. Place the stock pot on a burner on your stove and set the heat to medium. It should only take a couple of minutes, but allow your butter to melt.
Once your butter has melted, get out your marshmallows. We prefer to use a 16 ounce bag of Jet Puff Marshmallows. Jet puff is typically the most consistent in flavor and texture for us, but you can use whatever you like.
Dump the entire bag into the stock pot with the melted butter. Stir it around with your spatula until everything is completely melted and it has a nice yellow buttery sheen to it.
Step Two
Now that you have a melted marshmallow base, reduce your heat to low or medium low. We do this because you do not want to cook over cook the marshmallows. Overcooking marshmallows causes them to stiffen up really quickly, and it makes it very difficult to stir ingredients later.
Now it’s time to get out your Cocoa Puffs cereal. Take out six measured cups and dump them directly into the marshmallow mix.
Grab your spatula again and stir everything together. You’ll want to fold the marshmallows over into the cereal until everything is thoroughly coated and you have one big batch.
Step Three
With everything completely mixed and coated together, pull out your 9 x 13 baking pan and canola oil baking spray. Spray the inside walls and bottom of the pan to keep it from sticking later in the process.
Scoop all of your Cocoa Puffs cereal bar mix from the pot and into the baking pan. Spread the entire mixture evenly across the bottom of the pan and flatten until it is completely level.
Now set it to the side and let it cool for about 20 minutes.
Step Four
Once your Cocoa Puffs cereal bars are cool you can cut them. Take out a sharp knife and start cutting them into 2 by 2 inch squares. Depending on how good you are at eyeballing measurements, you should be able to get between 15 and 16 squares from a 9 by 13 pan batch.
Serve and enjoy!
