Marshmallow Cereal Bars

These marshmallow cereal bars are a fun snack, breakfast on the go and great for lunch boxes. Use your favorite cereal and enjoy!

Cheerios remind me of tea parties, because tea parties when I was a kid consisted of cheerios and water. Rather extravagant wouldn’t you agree? Back-in-the-daaay there was only one kind of cheerio and it came in a giant yellow box. It finally dawned on me while in the cereal section  that there are a TON of different kinds of cheerios now. I mean there’s apple-cinnamon, fruity, multi-grain and CHOCOLATE! I don’t mean to sound whiny *ahem General Mills* but why couldn’t you have sported these flavors when I was a kid?

Sugar cereals were totally banned from my childhood pantry… but I bet ya fifty bucks that if it had Cheerios on the front my Mom would have bought it! The fruity Cheerios would’ve easily replaced the leaves-your-breath-smelling-like-stinky-feet yellow box for sure. Just sayin.

Okay. Back to the cereal bars. These are like Rice Krispies Treats if you think about it. But jazzed up a bit.

I’m using the multi-grain with some oaty clusters… but as I said before, the fruity Cheerios would be SOOO rock solid in this recipe, maybe just minus the almonds and replace with… sprinkles!!

Marshmallow Cereal Bars l

Add a quarter cup of almond into the cereal and toss together with you impeccably clean fingers.

Line a 13×9 pan with some parchment paper to keep the bars from sticking to the pan. No sprays needed, promise.

Marshmallow Cereal Bars l

Melt butter in a large pot. I twirled the pot to get the butter up along the sides so the marshmallow would stick less.

Marshmallow Cereal Bars l

Add in the 6 ounces of mini-marshmallows. The regular size would work but it will take a lot longer to get those suckers to melt… and who has time for THAT?

Marshmallow Cereal Bars l

Keep on stirring…

When the marshmallows are just about completely melted add in the vanilla.

If there are a few lumps it’s really no bigs. Who would cry over a lump of marshmallow in their cereal bar? Uhhhh not this girl.

Marshmallow Cereal Bars l

Dump in the cereal and almonds.

Marshmallow Cereal Bars l

Mix it all around until the melty-marshmallow goodness is through-out.

Plop it into the 13×9…

I quickly greased up my fingertips with some coconut oil and pressed the cereal mound into the pan. It takes all of two seconds.

Now just sit and stare at it while it cools. Painful… yes. But totally worth it. When I’m making Rice Krispies Treats… I never EVER get it to this stage of the game. We eat it straight out of the pan while still warm.

Marshmallow Cereal Bars l

The very moment they are cooled; remove and slice into twenty or so bars. Orrrrr don’t cut it at all… just eat it as one giant bar! How fun is that?

Marshmallow Cereal Bars l

This is my attempt and some pretty wrappers for the bars. Fail? Maybe. Thank YOU brown paper bags that I’ve had for 5 years and never seem to run out of.

The rest went into a storage container. A perfect afternoon snack or as a grown-up breakfast, now if there’s one perk to being a grown up then it’s being able to have marshmallow cereal bars for breakfast!

Marshmallowy Cereal Bars

Yield: makes 20 bars

Combine the cereal with the almonds and set aside.

In a large pot melt the butter. Add in the mini-marshmallow and stir until almost completely melted. Add in the vanilla and stir. Next add in the cereal/almond mixture and fold the cereal in with the marshmallow.

Dump the cereal mixture into a parchment lined 13x9 pan. With lightly oiled finger tips, press the cereal into the pan. Let the cereal cool for 20-30 minutes. Remove and with a sharp knife, cut the cereal into 20 equal sized bars. Store in an airtight container for up to one week.

    WHY have I never thought to do this?? I can't tell you how many times I have wanted to make rice krispy bars, look in the pantry and find the only thing I'm missing is the actual rice cereal (but there's always that big yellow Cheerios box), so I sit home sulking. I am making these ASAP!

    Thak you for this! I may well be 40-something but my favorite Marshmallow Cereal Treat is Lucky Charms and make them extra chewy by using 7 cups of cereal to 6 cups mini marshmallows

    This is such a great change up from your normal rice krispie treats!I thinkI'd prefer the crunch to the cherrios better too!

    Just found your blog, I think through Life, Cultivated if memory from last week is still correct. Love your photography, sense of humor and practical approach to simplicity.

    I am not ready to give up my Oreo's and Cheez-It's forever, but I can't wait to make my first homemade cracker, french dip sandwich, and now – cheerios treats.

    Your blog presents great

    still love your blog but i dislike the reader change – i.e. only preview, no more full posts. clearly, you can do what you want. i just wanted to give you feedback that i miss the full posts in the reader! but i'll eventually get over it if you never change it back. =)

    Hi Danielle~ I had to switch it in order for the feed to actually be delivered. I was getting messages that my feed wasn't getting sent to inboxes because it was too large! Until I can figure out a way to get it delivered, I'll have to keep it that way! SORRY!! But thanks for understanding!

    Oh my goodness! I love Rice Krispies Treats, so this is right up my alley!

    I love your all from scratch approach to cooking. I try to cook the same way at my house. (Of course, notice I said "try". 🙂

    I just made these! I ended up using a full 10 oz. bag of mini marshmallows and about 7 cups of cereal. I didn’t have any sliced almonds, but did add in a big blop (maybe 1/3 cup) of peanut butter instead of the vanilla. I bet crunchy peanut butter would be fabulous! Rather than dirty a pan on the stove, you can put the butter and marshmallows in a big bowl in the microwave for 90 seconds. Works perfectly every time 🙂

      Ooooh peanut butter… NICE!!
