This easy peanut butter breakfast bars recipe is made in one bowl in 30 minutes, and is loaded with fiber, protein & omega-3s to keep you full all morning long!
When I decided to start this website in 2016, I knew right away that this would be my very first post. These Healthy Breakfast Bars have been my constant companion for the last 15 years are are, hands down, my favorite recipe of all time.
These breakfast bars gave me energy through my career as a high school chemistry teacher. They helped me grow all the necessary parts of our very first tiny little human, and the second, and the third, and the fourth, and the fifth, and the sixth.
These healthy oatmeal breakfast bars sustained me as we moved across the country away form all our friends and family. Every night when my head hits the pillow and I close my eyes, I know one of these beauties will be waiting for me when I wake up. I love them. Truly I do.
I mean, what’s not to love? These breakfast bars are full of fiber, protein, potassium, omega-3s, and are SO delicious. They are gluten, dairy and refined sugar free, but they are hearty enough to keep you full for hours. And they’re easy to make! To me, they are perfect.
Healthy Breakfast Bars: Ingredients & Substitutions
I get a lot of questions about possible substitutions for this breakfast bar recipe, so let’s chat about them now! A great thing about this recipe is that it’s fairly customizable.
- Quick Cookingย Oats. Old fashioned oats work well, using them will result in a chewier texture.
- Almond flour/meal: If you’d prefer to not use almond meal, omit it and increase the amount of oatmeal by ยฝ cup.
- Ground Flaxseed:ย You may substitute ยฝ cup of almond meal or extra oats in place of the ground flaxseed.
- Protein Powder:ย This is an optional ingredient. I love using Vanilla Protein Powder for a little flavor and protein boost, but you can omit it entirely if you don’t keep this ingredient on hand!
- Honey:ย maple syrup is a good substitute. Or, add an extra banana or an extra ยผ cup applesauce instead if you’d prefer a less-sweet, sugar free option.
- Peanut Butter:ย ย I use creamy or crunchy and choose your favorite variety.
How to Make Breakfast Barsย
Since I have made this breakfast bar recipe every week for 15 years now, I’m pretty sure I could make them in my sleep! However, in order to be helpful I want to walk through all the steps in this recipe for you.
Combine Wet Ingredientsย
To make these breakfast bars in one bowl, start by mashing the banana. I use a potato masher, but a fork would work as well.
Then add the rest of the ingredients and stir until the mixture is uniform throughout!
Add Dry Ingredients
Next, add all the dry ingredients to the wet mixture and stir to combine.
As you can see, the final mixture should not be runny. It should be moist but not at all liquidy.
Bake for 20 Minutes
This healthy breakfast bars recipe requires two sessions of baking. First, bake the breakfast bars naked (without any peanut butter on top) for 20 minutes.
The top should be slightly firm when the breakfast bars are removed from the oven. Since all ovens are different your baking time may vary slightly. However, it is important that the top isn’t mushy and that you can spread peanut butter around on it without it becoming a mess!
Top With Peanut Butter
After 20 minutes of baking, remove the oatmeal breakfast bars from the oven and spread a layer of peanut butter on top. The amount you use will depend on your taste.
I enjoy a super thick layer of peanut butter, so I use about 1/4 to 1/2 cup. Use as much or as little as you’d like!
Bake for 10 Additional Minutes
Return the breakfast bars topped with peanut butter to the oven for 10 more minutes. This step sets the peanut butter and finishes baking the bars.
As you can see, the final product will have nice little sinkholes of peanut butter on top! YUM!
Chill Overnight
These breakfast bars are best served cold. I always make them the day before I want to eat them and let them cool in the refrigerator overnight.
I have eaten them warm when I didn’t have my act together and they’re still good, but not as good if catch my drift!
Cut & Enjoy
Finally, once the breakfast bars have cooled in the pan overnight, cut them into squares and enjoy! Or you can cut them and save them for later! I always cut them into 9 breakfast bars, because it’s the perfect size breakfast for me to enjoy with a green smoothie.
Store/Freeze
I make a large batch of these (sometimes a double batch) to eat all week long. Wrap them individually in plastic wrap and store them in an airtight container in the refrigerator for up to 1 week or in the freezer for up to 2 months. Thaw slowly in the refrigerator (do not microwave).
Breakfast Bars Recipe FAQs
To store these breakfast bars, simply cut them and put them in an airtight container in the refrigerator. If you think it will be over a week before you finish them all, I recommend wrapping them individually in plastic wrap and then putting them in an airtight container.
If stored in an airtight container in the refrigerator these breakfast bars will last for up to one week!
Yes, double the ingredients and bake in a 9×13″ pan. You may need to bake them 5 minutes longer.

Healthy Peanut Butter Breakfast Bars Recipe

- 1 ยฝ cup quick cooking oats
- ยฝ cup almond meal

- 2 teaspoons ground cinnamon
- ยฝ teaspoon fine sea salt
- 2 Tablespoons vanilla protein powder (optional)
- 1 teaspoon pure vanilla extract
- 2 overripe bananas (mashed)
- ยฝ cup unsweetened applesauce
- ยผ cup creamy peanut butter
- 2 Tablespoons honey (or maple syrup)
Topping
- โ cup creamy peanut butter
Instructions
- Preheat oven to 350 degrees F. Grease an 8×8 square baking dish
- In a small bowl combine the dry ingredients (oats, almond meal, flaxseed, salt, cinnamon and protein powder if using), set aside. (alternately add the dry ingredients after mixing the wet ingredients).
- In a large bowl mash the banana. Add applesauce, honey, 1/4 cup peanut butter and vanilla. Mix well.
- Stir dry ingredients into wet until combined. Spread mixture into the pan (should be moist but not soupy).
- Bake 20 minutes (should be slightly brown around the edges and top should be set), remove from oven and spread peanut butter over the top of the bars (I like a really thick layer of peanut butter but itโs to your own preference)
- Continue baking for 10 minutes more or until firm and lightly browned around the edges. At this point the peanut butter layer will have tiny little bubbles in it.

Oh my! These are so good that even my meat eating hubs loved them!
I like this post wonderful thanks. for tasty recipes
Can’t wait to try these! Thank you for sharing!! Did you use sugar free applesauce or regular?
Unsweetened! But either works.
Hi Laura,
I have oat flour – can I substitute the quick oats and use oat flour? Would be a 1:1 substitution? Thanks in advance!
I have not tried it – I imagine it’d work but you might need to add less.
absolutely amazing! best thing I ever ate. everything Iโve made from lauraโs recipes ha turned out 100% perfection. the banana bread was out of this world. thank you
Thank you for this recipe it’s absolutely delicious! I just made them with a little bit of dark chocolate chips swirled into the top layer of peanut butter… I’m not sure they will make it to the fridge. ๐คค
Iโm in love with this recipe! Im always trying to find ways to incorporate flax seed into anything – I bought a huge bag when I was trying to boost my breast milk supply & I loved the health benefits of it, but never thought I could use it for anything else after exhausting many ways of sneaking it into recipes! Haha. But it just so happened I was looking for make ahead breakfasts & ran into this recipe! So I followed it as best I could with what I had. The changes I made were that I didnโt have any plain oats so I used cinnamon apple oatmeal. & I didnโt have any bananas or apple sauce so instead I added more peanut butter & used a small amount of apple juice. & wow. I have gotta say, itโs amazing! I was worried bc of the changes I made, but it honestly tastes like apples & peanut butter (one of my favorite snacks) but in like a granola form. Thanks for the recipe! I know my kiddos are gonna love it too!
I don’t have flax seed meal .Can i just add A super seed mix? It has Sunflowers pumpkin seeds, chia seeds , hemp seeds and flax seeds
I was informed by a friend who bakes more than I do that you can sub in the same amount of extra almond flour (also called almond meal). If you use the seed mix, I would suspect they’d need grinding up a bunch since “meal” refers to the seeds being ground up.
Would love to try! We have a nut allergy though. Suggestions to substitute the almond meal?
Simply replace it with an additional 1/2 cup of oats!
Loveeee these! I have used almond butter, both types of oats (old fashion and quick), powder PB- all turned out great! I have also added a layer of Hope Chocolate Spread (itโs plant based from Costco!!) and then some coconut flakes on top after baking. So good every time! This is a new staple in our house!
Thank you so much Kelsi! Since this is my all-time favorite recipe it always brings me joy when others enjoy them as well!
