How To Make Peanut Butter Oatmeal Protein Bars
Mainly, a protein bar is always made of nuts and protein powder to boost protein intake.
Ingredients
These oatmeal protein bars are made with 6 simple ingredients 100% vegan:
- Peanut Butter – choose natural, fresh peanut butter. It needs to be runny when taken out of the jar. Peanut Butter has a habit to dry up if left in the jar for too long. If you only have raw peanuts, you can make your own using my peanut butter recipe.
- Brown Rice Syrup – you can use maple syrup or coconut nectar instead by I prefer brown rice syrup as it is less sweet and releases slower in the body after sport.
- Rolled Oats and Jumbo Oats – I used a combo of jumbo size oat and rolled oats to add some texture to my bars. Make sure to use certified gluten-free oats if you are celiac.
- Vegan Dark Chocolate Chips – optional, but I love it!
- Vegan Pea Protein Powder – I used a vanilla one to add some extra flavor.
- Coconut Oil or Almond Milk – I prefer to use coconut oil as it makes the bars hold together better, If you prefer to use almond milk, pick unsweetened almond milk, but you can choose the plant-based milk you like.
Instructions
You can read the short instructions in the recipe card, but here are my important tips.
Combine the natural peanut butter, liquid sweetener (maple syrup, coconut nectar, or brown rice syrup), and coconut oil (or plant-based milk) in a saucepan.
Keep the saucepan under medium heat to melt the ingredients and form a runny batter.
Combine the rolled oats, vegan protein powder, and dark chocolate chips in a large mixing bowl.
Pour the lukewarm melted peanut butter mixture over the dry ingredient mix and store the peanut butter oatmeal protein cookie batter with a silicone spatula.
The dark chocolate chips will start to melt because of the warm peanut butter, it will make them softer to eat.
Setting The Peanut Butter Protein Bars
Transfer the batter into a square 9-inch x 9-inch brownie pan lined with parchment paper and flatten the top with your spatula.
Add a few more chocolate chips on the top for decoration and pop the bars in the fridge for one hour or in the freezer for 30 minutes to set.
Once the bars have set, take them out of the fridge, out of the pan, and cut them into 10 small bars.
You can, of course, flavor your bars with anything else you like. Here I topped my bars with chocolate chips but you can add vanilla extract, pecan nuts, puffed cereals, chia seeds, or even vegan candies.
The texture of these bars is chewy, with a lovely coconut flavor and bites of oats all around the bar. It is not too sweet but very fulfilling. I made 9 bars with this recipe.
Then some cereal is usually rolled oat because it makes a perfect base to boost complex carbs before running. Finally, sweeteners are most of the time brown rice syrup as it contains less sugar than honey.
Storage Instructions
These bars can be stored for quite some time because they contain no eggs or dairy.
You can keep them in the fridge for up to 3 weeks as long as they are in an airtight container.
If you store them in the pantry, you can keep them for about a week, but their texture will be softer so I prefer the refrigerator option.
Allergy Swaps
If you need to swap any of the ingredients for allergies, you can safely do the following substitutions:
- Peanut Butter: you can replace it with any other seed or nut butter such as almond butter, cashew butter, or sunflower seed butter.
- Brown Rice Syrup: you can replace the brown rice syrup with any other liquid sweetener such as coconut nectar, maple syrup, or even honey if you’re not vegan.
- Pea Protein Powder: if you can’t process pea protein powder, you can use any other vanilla protein powder such as soy or peanut protein powder. I don’t recommend using whey protein powder here as it’s not vegan and drastically reduces the shelf life of the bars.
Frequently Asked Questions
Quest protein bars are full of very highly processed ingredients. This is why it’s always better to make your own peanut butter protein oatmeal bars.
This recipe is full of simple, healthy ingredients.
I really like to use Macro Mike’s protein powders. They are natural, healthy, and made with peanut or almond proteins.
RXBARS are made with mostly healthy, wholesome ingredients, so it’s not a bad option for you.
I’d always favor making my own protein bars over buying commercial ones, but RXBAR is one of the better ones.

I have made this recipe several time and it is great!
I have started adding water when mixing the peanut butter to make the mixing easier. It has significantly improved the process.
Thanks for sharing!
Hello, would it be possible to swap the oats for quinoa? Or would that not keep well? If so how much quinoa would you say to use? Thank you
I am not sure, I never try that before sorry. XOXO Carine
Can I use almond butter for this recipe
Sure! Any nut butter will taste amazing. Enjoy, XOXO Carine
Hi,
I don’t have access to pea protein. What else could I use as a substitute? I live in Tanzania.
Thank you
Melissa
Hi Melissa, that is totally fine! The recipe would work perfectly without it, the bars might be a bit softer. Otherwise use a tablespoon of any other protein powder you can find or either coconut flour ! Enjoy the bars. XOXO Carine
Could ground flaxseed be used?
Instead of protein powder? It might work, yes.
Hi Again thanks for reply, one more question,,, so for the 10 bars its 10g per bar,,, with one tbl pwoder thats 15g for recipe…is the remainder of protein coming from the peanut butter thanks nigel ….they are very good by the way, my chocolate melted abit much but looked good
Yes! There is the full nutrition panel available just after the recipe card, scroll down a bit more and you can see it. I am so happy you enjoyed the bars! XOXO Carine.
Hi, I was wondering for the protein powder…..How many grams of protein are in the pea pwoder….Is it 100grams for the 1 tablespoon Thanks..Actually i just made recipe, if left in fridge are they still quite soft thanks Nigel
I am using this protein pea powder – it contains 20 g protein per serve (2 tbsp/30g). Those bar are no bake bars so they stay quote soft anyway. They should harden slightly in the fridge tho. Enjoy the recipe on the blog! XOXO Carine.
Hi! I would like to make these, but I don’t have any brown rice syrup. Could I make these with maple syrup instead? Thanks 🙂
Hi Michelle, Sure you can! Any liquid sweetener will work. I love using brown rice syrup but maple syrup, honey or agave will work as well. Enjoy the recipe ! Thanks for reading the blog and testing my recipes! xoxo Carine.
