These Cap’n Crunch Cereal Treats will bring out the kid in anyone. Each crunchy bar is loaded with gooey marshmallows and can be made using plain Cap’n Crunch cereal or Crunch Berries.
Did you grow up eating Cap’n Crunch cereal? How about Rice Krispie Treats?
Imagine blending these childhood favorites together to create these crispy, crunchy, chewy, Cap’n Crunch Cereal Treats.
We’ve had so much fun using a variety of kid-friendly cereal to create delicious marshmallow cereal treats including Fruity Pebbles Rice Crispy Treats, Cocoa Krispie Treats, and Froot Loops Cereal Bars.
These new treats made using Cap’n Crunch Berries Cereal are my absolute favorite, so far! I really thought they would be too sweet but they were not as sweet as expected. These bars really taste like cereal and milk.
Unlike a traditional rice crispy treat, that is made using small crisp rice cereal, these treats made using Cap’n Crunch Berries Cereal have much fewer cereal pieces to blend with the marshmallows, so you really see the gooey marshmallows when you look at these bars.
I really enjoyed the fruit flavors of the Crunch Berries but you can definitely make these with plain Captain Crunch cereal.
I also love the bright colors of the berry shaped cereal balls. These treats are colorful and fun enough to serve for a birthday party but are easy enough to make for an afternoon snack.
Let’s make cereal treats.
You’ll Need:
- 4 tablespoons of European-style salted butter (this will give you the absolute best flavor)
- 10 ounces Kraft Jet-Puffed Marshmallows (store brand marshmallows might be a bit stickier, so you may need to add more cereal if you use store brand marshmallows)
- 6 cups Cap’n Crunch Crunch Berries Cereal
- 8-inch or 9-inch pan (well-buttered or sprayed with non-stick baking spray)
Stovetop method:
- Begin melting the butter in a saucepan set over low heat.
- Then add the marshmallows and stir occasionally until about 75% of the marshmallows are melted.
- Remove the pan from the heat and continue to stir, smashing the marshmallows using a rubber spatula or the back of a wooden spoon, until the marshmallows completely melt and become smooth.
- Stir in the Cap’n Crunch Berries Cereal.
- Pour into a well-buttered 8-inch or 9-inch square pan.
- Allow to cool for at least 1 hour before cutting into rectangles or squares.
Microwave Method:
- Combine the butter and marshmallows in a large microwave-safe bowl.
- Heat on high power for 1 minute then remove and stir until the melted butter blends with the marshmallows.
- Keep stirring until the marshmallows melt.
- If needed, reheat for 15-second increments, stirring after each, until the marshmallows are fully melted.
- Stir in the Cap’n Crunch Cereal then spread into a well-buttered 8-inch or 9-inch square pan.
- Give the cereal treats time to cool before cutting.
Pro Tips
- Do not overheat your marshmallows.
- If marshmallows get too hot, the sugar will begin to caramelize, thereby making your treats hard and crunchy instead of gooey.
How to store cereal bars
- These treats are best the day they are made but they can be kept in an airtight container for up to a week.
- If you refrigerate the treats, the cereal may become too soft.
- If you wrap the treats well in non-stick tin foil then place in a zip-top bag you may freeze the treats for up to a month. To thaw set the treats on your counter for at least 1 hour before un-wrapping the treats.

My daughter begged me to make these for her and she wanted me to tell you that they were the best dessert we’ve made during the time we’ve been stuck at home. I’ve made cakes and cookies and even pies and she loved these treats made with 3 ingredients the best. HaHa. They did taste better than I ever imagined and they made her very happy.
