Captain Crunch Cereal Bars are the perfect combination of breakfast food and marshmallowy goodness. The best part is this recipe is quick, easy, and requires no baking at all.

How to Make Captain Crunch Cereal Bars
I’m sure everyone is quite familiar with Captain Crunch cereal. So it should come as no surprise that there are also Captain Crunch Cereal Bars. Nothing is better than the delicious, sugary flavor of puffed sweet corn and marshmallows.
If you’ve ever made cereal bars before, you know they are not a lot of work but have a HUGE snack payoff in the end. Captain Crunch Cereal bars rank right up there with Cocoa Puffs cereal bars, Trix cereal bars, Trolls Rice Krispie Treats, Cookie Crisp Cereal Bars, and Cinnamon Toast Crunch Cereal Bars for best cereal bar treats.
Let’s get started!
Step One
Set a large stock pot on your stovetop. Using medium heat, start melting your butter.
After a few minutes, add in a full 16 ounce bag of Jet Puff Marshmallows to your mostly melted butter. Use a spatula to stir the marshmallows and butter together until they have completely melted together.
We prefer Jet Puff Marshmallows. They tend to have the most consistency in flavor and freshness. But any brand of marshmallows will do.
Once everything has melted together, reduce your heat to medium low or low and get out your Captain Crunch Cereal.
Step Two
Take 6 measured cups of Captain Crunch cereal and dump them into the marshmallow mixture. Again, using your spatula, stir everything together until it is thoroughly mixed.

Step Three
Once your cereal and marshmallow base is mixed, pull out a 9 x 13 baking pan. Spray the bottom and inside walls with canola oil spray. Any flavorless baking spray will work. We just prefer canola oil.
Take your cereal bar batter and scoop it into your pan. You can use your spatula to flatten the mixture into the bottom of the pan.
Now, set everything to the side for about 20-30 minutes and allow to cool before cutting.
*if you are impatient like we are you, can speed this up a bit using the fridge or even the freezer.
Step Four
Finally, once your treats are cooled, take out a sharp knife and cut them into squares. A full pan should yield around 15 to 16 squares depending on how narrow you cut them.
Serve and enjoy!
