Using Cap’n Crunch Cereal to create marshmallow coated bars is a favorite homemade treat for our kids!

Cereal is usually eaten for breakfast and almost always eaten as a bed-time snack in our house. I ask the kids to eat whole grain cereal most of the time, but sometimes we get some fun, colorful cereal like Captain Crunch.

When we want to go the extra mile we melt our own mini-marshmallows and stir in regular Cap’n Crunch. Spread out in a 9 x 13 pan and allow to set for no-bake cereal bars.

Ideas for Other Easy Cereal Bars

I’ve made so many different versions of cereal bars from Cocoa Puffs Bars to Oreo Cookie Krispie Treats and Reese’s Puff Cereal Bars, they are ALWAYS a hit at parties and meals with kids.

If I want to impress my kids around the holidays I grab a box of cereal and whip up a batch of Halloween Treats Valentine’s Day Treats, or Christmas Chex Mix.

On a recent trip to Kroger one of the ladies was offering samples of these Captain Crunch Cereal Bars and I knew I had to make them at home.

After making these for a family party my son decided to make a batch himself a few days later. He was so proud of his accomplishment and super excited to share.

Tips for Making Cereal Bars

  • Always use fresh cereal and marshmallows
  • Stir marshmallows often during melting process to avoid burning
  • Keep fingers wet to spread out in a 9 x 13 pan
  • My son likes to cut the recipe in half because it’s easier for him to stir and manage
  • Stale cereal will make your bars hard, crunchy and difficult to cut
  • Stale or burnt marshmallows will make the recipe extra gooey and taste bad

We have a little challenge in our house where people don’t understand how to fold down a bag of opened cereal to keep air out. Or little hands tear open a bag of marshmallows to grab a handful and then leave the bag open to get a bit stale.

So use fresh marshmallows and keep stirring them often during the melting process. As soon as they have melted remove from the heat and stir in cereal to avoid burning marshmallows.

How to Make Cap’n Crunch Bars

  1. In a large saucepan melt butter over medium heat; stir in marshmallows and stir often until melted.
  2. Pour cereal mixture into a greased 9 x 13 inch pan. Wet fingers to spread out mixture.
  3. Allow about 20 minutes to set-up, cut and serve.

Step By Step Instructions

Lightly coat a 9 x 13″ dish with non-stick cooking spray.

Prepare the ingredients by opening the marshmallows and measuring out the cereal before starting to make the Captain Crunch Bars.

Over medium low heat melt half a stick of butter in a sauce pan.

The marshmallows don’t need to melt completely because they will continue to soften once removed from the heat.

Turn the burner off and move the pan to a cool part of the stove.

Pour cereal into the pan.
