With just a handful of ingredients, these no-bake bars are loaded with flax seeds, oats and nut butter, which means they pack a healthy punch of omega-3 fatty acids, fiber, antioxidants, protein and a plethora of vitamins and minerals, yet, you will feel like you are eating dessert! Who doesn’t want that?
Ingredients you need
Peanut butter, oats, maple syrup…need I say more?
Many people love granola bars, but most of the ones you find in the store have some questionable ingredients.
These No-Bake Peanut Butter Oatmeal Bars are creamy and chewy, with a little crunch for texture and optional chocolate drizzle. The best part — they are good for you!! Gluten-free, oil-free, and vegan!
Ingredient notes and substitutions
Oats ~ Use old-fashioned rolled oats for best texture. Quick oats can be used in a pinch, but do not use steel cut oats.
Cereal ~ I love the crunch that crispy brown rice cereal provides. It’s a nice contrast from the chewy oats.
Note: Many cereal brands add vitamin D3 derived from animals and are, therefore, not vegan. If this is important to you, be sure to choose a vegan variety, like Nature’s Path, Barbara’s, or One Degree.
Flax ~ Use flaxmeal, not flax seeds. You can either buy flaxmeal from the store or grind your own flax seeds easily at home in a small coffee grinder. A food processor can be used as well.
Flax is high in fiber, healthy fats, and protein.
If you don’t have it or can’t have it, you can use ground chia seeds or leave it out and add additional oats instead.
Peanut butter ~ For the healthiest option, choose an organic, natural peanut butter. The only ingredients should be organic peanuts, and maybe, salt. I prefer creamy peanut butter, but you can use crunchy if you like.
You’ll need to stir this kind peanut butter before using as the natural oils separate and rise to the top. It can be quite difficult to stir in the jar. I recommend transferring the entire container to a large mixing bowl, stirring well until perfectly smooth, and then transferring back to the original container. If you store it in the fridge, it shouldn’t separate again.

For a nut-free option, try using sunflower seed butter instead.
Sweetener ~ Pure maple syrup is my sweetener of choice. It’s delicious and provides the liquid needed for this recipe.
Extras ~ I like to drizzle chocolate over the top of these easy no-bake bars before serving, but you can stir in chocolate chips, if you prefer. You can also add a scoop or two of protein powder, nuts or seeds, dried fruit, or a dash of cinnamon.
How to make the recipe
Stir together the peanut butter and maple syrup (1) until smooth (2).
Add the oats, crispy rice cereal, and flaxmeal (3) and stir well to combine (4).
Press the mixture firmly and evenly into a parchment-lined 8×8 baking dish. Place in the fridge for 20 to 30 minutes to firm up.
Cut into squares and enjoy!
Note: I cut this batch into 9 squares, but they are quite large and very rich. I suggest cutting into 16 squares instead.
Storage/Freezing
Storing: Store them in an air-tight container in the fridge and they will stay firm, yet still be soft and chewy. Leftovers will keep well for up to a week.
Freezing: You can also freeze these Peanut Butter Oatmeal Bars. Cut them into bars and place them in a single layer on a large plate or baking sheet. Transfer them to the freezer for about an hour or until frozen. Once frozen, transfer the bars to a freezer-safe plastic bag with pieces of parchment in between each bar. They should keep well for up to 3 months. Let thaw slightly before serving.
Pro tips and tricks
~ Use old-fashioned rolled oats, not instant or steel cut.
~ Don’t skip the crispy brown rice cereal. It adds great crunch!
~ Use an organic, natural peanut butter.
~ If the peanut butter is very thick and you’re having trouble mixing it easily, you can microwave it for a 10 to 15 seconds to thin it out.
~ Stir really well! Be sure to scrape the bottom of the mixing bowl to fully incorporate all of the ingredients.
~ Press the mixture firmly in the baking pan.
~ Drizzle with chocolate. Optional, but delicious!
~ For a nut-free option, use sunflower seed butter.
~ For gluten-free, be sure to use certified gluten-free oats and brown rice cereal.
FAQs
Most store-bought bars and many recipes you’ll find online are not very healthy. They typically contain butter and loads of sugar. This version contains no oil, no butter, no flour, and only unrefined pure maple syrup. They’re full of fiber, protein, healthy fats, vitamins and minerals.
If you are gluten-free, be sure to use certified gluten-free oats and crispy brown rice cereal. While they are naturally gluten-free, those products are often processed in facilities that also handle ingredients with gluten and may have cross contamination.
Yes! These bars freeze beautifully! They will keep well up to 3 months.
These bars are no-bake and are, therefore, more crumbly than baked goods. Be sure to press the mixture firmly into the pan and allow them to firm up in the fridge before slicing in bars.

These are truly delicious, and versatile. I didn’t have crisp brown rice cereal but figured 1 cup of anything “crunchy” would do. I made one batch of your bars using honey nut chex rather than the brown rice, and another batch using muesli. They were both amazing. I topped mine with fresh strawberries in the morning and OMG! Thanks for a recipe I’ll go back to again and again. I added a pinch of salt and splash of vanilla, too.
Jenn Sebestyen
Wonderful! Glad the substitutions worked for texture. Thanks for your comment!
jacquie
these look great but uncooked oatmeal doesn’t agree with me. Could i bake them?
Jenn Sebestyen
I haven’t tried it. I would say technically you can bake them, but I there isn’t enough liquid in the recipe to change the texture of the oats.
Sara
These are YUM! My husband left for a week-long business trip the day after I made them. He was bummed he didn’t get any more; however, I was quite happy that I got to eat almost all of them! The only bad thing about these was that we had chia seeds stuck in our teeth – not so pretty to look at! Is it okay to grind chia seeds or does that affect the nutrient content in some way?
Jenn S.
LOL, that happens to be sometimes too, Sara. Yes, you can grind them down in a small coffee grinder or similar. Or just leave them out. I’m so glad you liked them!! They are the perfect snack! 🙂
ingrid rivera
can this be freezed?
greetings from mexico!
Jenn S.
Hi, Ingrid. I haven’t tried freezing them, but I would think they would do so perfectly! They are probably great straight out of the freezer actually! Let me know if you try it! Enjoy!
winwinfood
Oh yes please! All my favorite flavors put together! Love it <3
Jenn S.
Thanks, Lucie! They are definitely a favorite around here!
Kelsea Britt
These are delicious! This is a breakfast I can really get behind! I just used gluten free cereal and gluten free oats and voila…gluten free yumminess!
Jenn S.
Yes! They are sooo good. My son loves to take them in his lunch too!
Kelly
Do you think this could be adapted to use the PB2 powdered peanut butter?
Jenn S.
Kelly, I’m not sure. I have never used PB2. Do you reconstitute the powder to make a “butter” or is it just used as flavor in powder form? I’m guessing if it can be reconstituted, then it would work, as long as it’s thick enough to hold everything together. Sorry, I can’t be much more help. If you try it, let me know your results. Thanks!

These sound great. Going to make them for my picky son today. Where can you find nondairy chocolate chips?
Jenn S.
Thanks, Jennifer! I buy the Trader Joe’s Chocolate Chips which just happen to be vegan (not their chocolate chunks though!). Enjoy Life is another brand that is dairy free…they can be found at Whole Foods and probably other specialty stores. If your grocery store has a Natural Foods aisle you might get lucky and find some there. Let me know if you son likes them!
Jennifer Jackson
Thank you so much. I will go out to Trader Joes Friday.
Linda @ Veganosity
I’m not sure you could make these any healthier Jenn. They look so good!
Jenn S.
Thanks, Linda! Gotta make ’em uber healthy so I don’t feel so bad when I eat 3 at one sitting! 🙂
