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! Try these Peanut Butter Rice Krispie Treats or these No Bake Samoa Cookies too!

    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.

    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!

    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!

    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.

    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

    Would you adjust the amount of maple syrup if you were using conventional peanut butter (Skippy or Jiffy)?

      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.

    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!

    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!

    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!
