No-Bake Peanut Butter Oat Bars on 100 Days of #RealFood

I’ve got a new recipe for you today that’s technically part of my baking series. But no one will mind if you don’t actually have to bake them in the oven, will they? My girls seriously love them so much that they dance around the kitchen when they see me making them. :)

And I love it when I have a batch of these bars on hand because then I am prepared with yummy, filling snacks when I hear the inevitable, “I’m hungry…” These bars would also be a great way to supplement a lunch or even have as a quick breakfast with a side of fruit. I think the moral of the story is that it’s hard to go wrong with this recipe, so I hope you and your family enjoy them just as much as we do!

    I love this recipe! So simple yet delicious! I substituted the peanut butter for homemade cashew butter (my husband has peanut allergies) and the bars barely lasted the afternoon! Thank you for sharing this with us.

    These are sooo good! Great crunch! Not too much peanut butter for my family:) They were gone within a few days. Making more now….thank you!

    I made these and they were good, but I also thought it was way too much peanut butter. Either add more cereal and/or oats or reduce the peanut butter to a cup. I also found them to be crumbly.

    I made these yesterday and they are absolutely delicious. We enjoyed them this morning with our green breakfast smoothies (also a recipe from this website), and we all loved them. I would go so far to say that I prefer them over sugar-laden peanut butter cookies — they could totally pass as dessert. I made them as-is; I found Enjoy Life cereal at our local Whole Foods and for the peanut butter I used Adams crunchy and it worked great. I did not find them to be crumbly as others have reported. I used a spatula to spread out the mixture and made sure it was pressed very firmly into the pan. I chilled for about 4 hours before cutting and stored them in an air-tight container. This will definitely go into our grab-and-go breakfast rotation. Thank you!

  5. Do you think you could sub the Maple Syrup for Honey? Have a sensitivity to maple so I’m trying to eliminate from my diet. These look soo good, I ordered my flax cereal this weekend can’t wait to make them!

  6. Made these today and they did not disappoint. They came out a little bit crumbly, but I’m thinking it’s the peanut butter I used (Teddy’s). So glad I found this recipe and thank you for sharing it! They are so good!

  7. Hi – I love Lisa’s recipes and usually have good luck. I’ve made these twice exactly as instructed and they do not hold together. As soon as I try to cut them into squares they crumble. Super frustrating as they are not inexpensive to make.

  8. I just made these as I found the crunch flax cereal today at big lots! We haven’t tried them yet as they are chilling but it just seemed like way too much peanut butter compared to the 2 cups of cereal/oats. I think next time I would use only 1 cup peanut butter

      Hi Laura. Since flax seeds are so tiny, there would be a pretty big difference in volume. You could try nuts or a different whole grain cereal.

  9. This sounds so good. How sweet would you say they are? We don’t really do much sugar here. Also, what do you think adding mashed banana to this? I don’t know why but I love bananas in almost everything and would like to know what you think.

    Thank you!

  10. This looks delicious! You mention in the blog post honey and raisin juice concentrate. I don’t see those in the recipe.

  11. Thank you so much for introducing new whole foods but keeping it real!
    So many people are cooking with highly specialized food now and it’s discouraging for eating healthy to mean I must have high priced ingredients shipped in for every day cooking. I keep coming back to your site and cookbook because I can find what I need for your recipes at my local grocery. And, your recipes are healthy and delicious!

  12. What kind of peanut butter do you like to have on hand? I’m just starting out the cleaning eating and trying to find a good peanut butter, as I love peanut butter but know that JIF is a no no for this lifestyle change.

  13. Thank you for using Enjoy Life products in your recipe! My son has multiple food allergies and there company makes a lot of great products that are safe for people with food allergies. I will be whipping up a batch of these.

      While I don’t no exactly how to sub in this recipe. If you do a google search for no-bake gluten free cookies, you might find a recipe that you like. I know some use puffed-rice cereal.

  14. These sound amazing and so simple. Could they be frozen? I like to make big batches to use later. My kids always beg to eat a whole batch if they are just in our fridge :)

    I definitely don’t mind that these aren’t baked – it means there is significantly less time between prep and eating! The crunchy flax cereal looks delicious too :) do you think I could use buckwheat kernels as a substitute?

    I have another formula for you today that is in fact a piece of my preparing arrangement. Be that as it may, nobody will mind on the off chance that you don’t really need to prepare them in the stove, will they?

      Hi there. We use organic peanut butter with no added ingredients; just nuts and a little salt. These are not baked.

    Great recipe! My local grocery outlet actually had this exact cereal for just 1.49 a box!! I didn’t have maple syrup, so I substituted honey and actually cut that in half bc I don’t like too much sweetness. Whipped them up this morning and added a few mini chocolate chips pressed into the top. My boyfriend actually moaned with happiness when he tried them! Great recipe!

    Outstanding! And a good “base” recipe. I didn’t have the cereal on hand so I used chopped pecans. Oh my it was good. Now I’m thinking of other combinations. Thank you!

  19. I have all of these ingredients on hand (we are GFCF) What a good way to use up the 3 boxes of this cereal I bought my boys don’t care for it. Do you think you could add chocolate chips to it somehow? My kids probably won’t eat them otherwise!

      1. Yes, the chocolate chips are definitely needed, otherwise too peanuty buttery for us. Mine crumbled when I cut them, is this normal? I followed the directions exactly. Almost like they are too dry.

      2. Hmmm what am I doing wrong. I used Skippy peanut butter. I measured everything to, whereas I usually “eye” it in these types of recipes. Maybe add more syrup?

    1. There is a store locator on the product website – looks like Whole Foods, HT and Bilo’s all carry this cereal :-)

    1. If you go to the company’s website they have a store locator for their products. You choose the product and they give you a list of stores close by. Many stores around me carry them!
