"O" Cookies!



For most people, the "O" in these "O" Cookies will stand for the type of cereal used to make them. But for me, the "O" stands for obsessed, because that is what everyone in my family has become since I started making these cookies.

Starting from the time my kids had them as one of their very first finger foods, Trader Joe's O's have remained a household favorite. Between Chloe scarfing dry fistfuls of it every morning for breakfast and Kenya slurping it down with rice milk by the bowlful, we go through a lot of O's each week. In an effort to make food exciting for kids, I'm always trying to take ingredients they love and feature them in recipes they'll hopefully adore even more.

This is my healthy take on the cereal bars you can buy at the grocery, but I used "O" cereal and decided to mold them into a cookie shape instead of a bar. These aren't exactly a tough sell no matter what shape you make them into, but I find going with cookies adds to the fun visual appeal. Not to mention I sometimes feel like I could serve my kids drywall for breakfast and simply by calling it a cookie would increase its chances of being consumed tenfold.

No matter whether you decide to make cookies, bars or balls, have fun making them and be careful, they're totally addictive. "Oh" yeah!!

For most people, the "O" in these "O" Cookies will stand for the type of cereal used to make them. But for me, the "O" stands for obsessed, because that is what everyone in my family has become since I started making these cookies. Starting from the...


  • 1/2 cup nut butter (almond, peanut or sunflower)
  • 1/2 cup rice syrup
  • 4 cups o’s cereal (you can use whatever “o”-type cereal you like: cheerios, trader joe’s o’s, etc.)


  1. 1. Place the nut butter and rice syrup in a small saucepan over low to medium heat and warm for 2 minutes or until it becomes smooth and combined.
  2. 2. Place the cereal in a bowl.
  3. 3. Pour the warm nut butter/rice syrup mixture into the bowl with the cereal and stir to combine.
  4. 4. Shape into cookies (I used a mini ice cream scooper to scoop out each portion, but you could also use a tablespoon). You can also place the mixture into a 9 x 9 inch ungreased pan, pat down and then cut into bars. As the O’s mixture cools, it will harden.
  5. 5. Serve.
O Cookies!

    What’s a good substitute for rice syrup?

    • C. McCord

      The brown rice syrup is what holds everything together and is a replacement for corn syrup which you will find on other similar recipes, so it is a necessary ingredient!

    Would love to make these but any ideas of what we can use instead of rice syrup? We try to stay away from all things rice because of the arsenic which is particularly high in brown rice syrup. Thanks!

      If he is pretty good at chewing solid foods then these should be okay. They aren’t chewy like rice krispy treats. They’re softer!

    Made these with the 5-yr old last night, using sunflower seed butter and organic chocolate-O cereals. Super easy and really tasty. I cut back just a bit on the cereal based on comments about the mix falling apart, and had no issues. He insisted on taking them to daycare this morning to share – can’t wait to hear how the other kids liked them!

    I made these tonight. I thought they were really easy and all my kids liked them. I think they’ll make a great quick breakfast on a busy school morning. I by the way, used corn syrup because it’s what I had (sugar is sugar in my opinion) and they turned out perfectly. Great idea, great recipe!

      Thank you for the comment about corn syrup. It’s all I have on hand, but it didn’t occur to me to use it. It’s not the same thing as high fructose corn syrup, people!

    Saw this on the recent Facebook posting…. PERFECT cookie replacement for my toddler! The Brown Rice Syrup was easy to find at Sunflower Market ($5 for a jar that will make 5 batches) combined with Simply Jif peanut butter. Microwaved for 2 minutes and mixed it all up with the cereal. (Oh, and a previous commenter mentioned vanilla extract – so I added a squirt of that too.)

    I used my little disher to make little cookies, but I think next time I’ll take another commenter’s suggestion of using my hands with a coconut oil on them to keep from getting O-Cookie-Mitt!

    Last night Mama and Daddy were told in no uncertain terms that they could not have any more of KJ’s cookies – so that shows you how good they are! :)

    Thanks for the wonderful recipe, Weelicious is becoming my go-to for food suggestions for my picky little man!

    i made two batches today
    #1~I love how fast these can be made.
    #2~ I made them both with O’s and GF and both were awesome.
    I didnt have rice syrup so I ued ricemellow which is rice syrup with air basically like fluff
    I increased the rice syrup amount to about 1 cup of the rice mellow (since its mostly air. I used a GF cereal that was ball shaped. They didnt stick together so well. Next time I will use 3.5 cups of GF cereal so that they are coated better.
    I used the O’s for the second batch. Oh my yummy. my new automatic go to for quick afternoon snack choice.
    yesterday we made the dutch baby and tomorrow fruit and seed bars. Thank you so much for the amazing recipes

    The first time I made these, I tried substituting the rice syrup with maple syrup (not one for one), but the “Os” didn’t stick together well. Today, I’m trying with rice syrup, making bars instead of cookies, and I hope it works. I’m taking them to a party tonight!

    I just made these and used the “Rice Crispy Treat” method my husband used as a kid. I heated the syrup and almond butter in a large pot, stirring to combine until smooth. It reaches a stage where it sticks together, and does not spread along the bottom of the pan, as it did before it was fully heated and combined. Then I turned off the heat and added the cereal, stirring quickly to combine (it is a nice workout for your arms, if you switch off). Then I patted it into a pan sprayed with coconut oil (so it will come out when cut). I chose the pan because the mixture is quite hot to touch for long, but it could make perfect balls, too. Turned out perfect for me. Thanks for the recipe! I have a lot of “O’s” to use up.

    As for other sweetener options…since I have made molasses candy, before, I think you could use it in this recipe. It might take a couple of experiments to get it right, though. You will need to heat the molasses until it thickens, maybe to thread or soft ball stage, and then stir in the nut butter, and then the cereal. I am sure it would require more molasses than rice syrup because you will be cooking it down, which would then increase your cost–not to mention the time and attention.

    I too made them & they stay together long enough to eat but then fall apart. I first tried to amke the bars but that was a disaster. They didn’t hold at all. So I tried to ball them up in my hand to make balls as in the picture & that was better but still fall apart. I used brown rice syrup & organic p.b. If there is somthing I am missing please let me know.

    • catherine

      October 19, 2010 at 6:32 pm

      Did you let them cool? Try using less O’s if you still have problems with it.

    • catherine

      September 20, 2010 at 2:42 pm

      Unfortunately, you would have to use rice syrup because of the its consistency. :( I wonder if you could email a company and ask them to package it in a plastic container?

    Can anyone attest to whether freezing these will work? They’re delicious but my kiddo won’t eat these all before they go stale! (How long do they keep, what’s the best way to keep them fresh longest – does putting them in the fridge help?) I made the ones with rice krispy-esque cereal and they went stale before we could finish them. Maybe individually wrapping them in plastic or parchment or something? Thoughts?

    • catherine

      September 20, 2010 at 2:55 pm

      Hmm – freezing would actually make them stale when you defrost. So weird that it becomes stale when you finish making them. I would use a different brand just to test it out again.

      I personally do not use corn syrup and have not tried it. It should have the same consistency as rice syrup. Do you have a health food store near you?

    I’ve been struggling with the healthy food thing with my two kiddos (who are both currently on hunger strikes!) when a friend told me about your site. I can’t thank you enough for all of your work and wonderfully creative (& yummy!) ideas! While my two aren’t eating at the moment, their parents certinaly are enjoying every recipe we try.

    One thing I found in making the “o” cookes (which I absolutely love!) – if you opt to shape these by hand, it helps to keep your hands damp with water to prevent a “o-cookie” mitt from forming 😉

    Hmmm, you know I made it exactly like the recipe says… put it in a pan hoping to cut it into bars and I had the same results as a few others :-/ it’s been in the fridge for about 2 hours now and I can cut it but when I try to pick up the pieces I cut it just falls apart :(

    I used Brown Rice Syrup and Sunflower butter. I’m thinking the problem was the sunflower butter… it was pretty thin, I could stir it easily straight from the jar. I think reg. PB would be better since it’s firmer.

    Might try it one more time.

    Also I made them with apple cinnamon cheerios (cause that’s what I had) and the taste GREAT!!! Yum, the cinnamon is a nice addition!!

    Will this work with organic molasses? The only place that I found that sells rice syrup has a small jar for $9 bucks and using molasses would make it so much more inexpensive.

      Wee2€™ll things such take yet anthoer look at to two styles of users: newly released Zune vendors who is going to be creating plans for an upgrade, and the ones performing this to come towards the conclusion between a Microsoft zune plus an ipod touch. (A good deal much more professionals worthwhile considering available to decide on from, which include the The new sony Personal stereo Times, nonetheless This certain this supplies you sufficient research to get the top thought from Zune rather of masters as apposed towards the iPod brand similar.)

      June 16, 2010 at 2:44 pm

      I have not tried it with soy butter and I have never tasted soy butter but you can. If the soy butter is not sweet as the sunflower butter, I would put a little more honey or agave in the mixture to bring out a sweetness. Let me know how it goes!

    June 10, 2010 at 6:31 pm

    I made them with brown rice syrup and sunflower butter but they never really firmed up. They stayed together enough to eat them and were very tasty. I’m just wondering how firm yours got?

    • catherine

      June 11, 2010 at 1:57 pm

      When the cool down, they firm up. You can always put them in a baking dish and let it cool and cut them into bars for a faster route! :)

    • catherine

      May 14, 2010 at 4:55 pm

      Unfortunately, Agave and Honey would not work because rice syrup has a sticky tacky texture and a neutral flavor that they do not. Also, rice syrup allows the mixture to stick together and it would not work well with agave and honey.
