Cereal Bars Recipe

Confession- I hoard leftover bits of cereal.

Although I don’t really enjoy cereal for ‘meals’ in itself, I do enjoy a bowlful as a snack before bed or when I want some texture, add it to Greek yogurt, cottage cheese or even ice cream.

Yes, ice cream. 

For some reason, I don’t really like the final handful in each bag. It’s usually made up of broken pieces of cereal, cereal dust and more cereal dust.

Saying that, I also despise wasting food so these all just pile up. A quick glance in my pantry would see close to seven cereal packets, all with barely a handful in each. However, in my grocery bag, I had a new box of crispy rice cereal. The reason for this new box of cereal was to make a weekly staple in this neck of the woods- Healthy 3 Ingredient No Bake Rice Crispy Treats.

How to make easy homemade No Bake Cereal Bars

Before I ripped open the new box of cereal to get some bar treatment, I thought for a second. Why not combine all the leftover bits and bobs of cereal and replace the crispy rice, cup for cup, and use said cereal instead.

The majority of my leftover cereal were these Whole O’s by Nature’s Path (a vegan and gluten free version of Cheerios) and some peanut butter puffins. I threw the muffins on some vanilla yogurt and combined all the remnants of Whole O’s to make a delicious, quick and easy 3 Ingredient no bake snack bar.


Saving money.

NO wasting.

Are cereal bars Healthy? 

These healthy 3 Ingredient No Bake Cereal bars literally take five minutes to prep and the hard part is waiting for them to firm up…although eating the ‘batter’ is totally acceptable.

This recipe is not impressive (and easy!) because they use three ingredients. Unlike store-bought packaged cereal bar, they contain no butter, no sugar, and no dairy, but you’d never tell.

Naturally gluten-free and vegan, they are also relatively low calorie. 

How do you get cereal bars to stick together?

  • I used this almond butter in one batch and this generic peanut butter in another. To be honest, I LOVED the latter (with all the added ingredients in it) and found it to have a much more delicious texture. If that doesn’t phase go, go for option two! 
  • Ensure cereal bars stick together by melting together your nut butter with your syrup of choice. It makes the bars hold up easily.

  • 2 cups dry cereal I used Whole O's- Cheerios would work if not strictly gluten free
  • 6 tablespoon almond butter can substitute for peanut butter or sunflower seed butter
  • 6 tablespoon brown rice syrup can substitute for maple syrup or agave nectar


  • Line a baking tray with baking paper and set aside.
  • In a large mixing bowl, add your dry cereal and set aside.
  • Stovetop or in the microwave, melt your nut butter with your sticky sweetener and then pour the mixture into the crispy rice cereal and mix well.
  • Pour mixture into the lined baking tray and press firmly into place. Refrigerate for at least 30 minutes to firm up.


Cereal bars are fine at room temperature but best to kept in the freezer or fridge for best texture.

    1. Yup yup yup simplicity at its finest. These would be perfect stored in the freezer. Then I may combine the new use of the cheerios into your marble rice crispy bars from a while back.

    2. Yuuummm. I don’t do creative things with cereal. I just eat it in a bowl. I think I could manage these, though 😉

    3. Silly rabbit, Trix are for kids. Oh wait. You didn’t use Trix. Ok then, maybe you aren’t so silly, mate. In fact, maybe you’re a genius! I love me a good cereal bar in the morning. Quick, easy and portable…what’s not to love there?? Can I top mine with colored sparkling sugar, though? 🙂

    4. I definitely don’t like to waste food! I love cereal. I add it to cookies for a little extra crunch, or add it to a mixture of nuts and dried fruit for some trail mix snack.

    5. What a neat recipe—these would be fun to bring to a party or something. I may or may not take it one step into the “are you f—ing kidding me” zone and make this with Cinnamon Toast Crunch…

    6. These would be great for party when I am in a hurry. And probably my picky niece too! I never have cereal as a meal b/c I find it so un-satisfying, but I love it as a snack!

    7. Omg I love putting cereal on my ice cream. There is just something about that combo of sweet, creamy and crunchy! Imagine if I put these crumbled cereal bars on my ice cream, now that’s what Im talking about!

    8. I HATE wasting food and I usually don’t. Probably because I’m Italian so I love to eat…and I’m that friend who always brings extra food to classes/rehearsals to make sure her friends are fed! LOL

    9. These sound amazing! I love how quick and simple they are to make. Plus they uses GF cheerios, which is basically like my favorite cereal, simply because it goes with any flavor and any food!
