Gluten Free and Vegan No Bake Protein Bar Recipe

No Bake Protein Bars Recipe

We love our homemade protein bar recipes on here. We’ve had our mint chocolate chip protein bars, easy no bake protein bars, and cinnamon roll protein bars

The inspiration for these 4 Ingredient No Bake Protein Bars was sparked several years ago when I was weight lifting consistently.

 The gym I was part of offering a complimentary personal training package for all new recruits and I was offered three sessions. The second session with my trainer saw him offer me nutrition advice, the biggest one being ‘eat a balanced post workout snack of protein and carbs’.

He recommended me to blend a banana with protein powder and milk but at that time, the thought of smoothies made me want to gag. He suggested a simple bowl of oatmeal with protein powder mixed in.

Protein powder and oatmeal became my standard post-workout meal but eventually, the university started again and I didn’t have the luxury of microwaving a bowl in the comfort of my home. Instead of resorting to the shakes, I would just combine the oats, almond butter, maple syrup with protein powder and enough to milk to make a ‘dough‘ and would chow on that straight after the gym and this replaced the oats. 

Naturally vegan, gluten-free and refined sugar free, these easy no bake protein bars take less than 5 minutes to make!

How to make easy no bake protein bars with oatmeal and peanut butter

Homemade Protein Bars Ingredients

  • Gluten-Free Rolled Oats
  • Almond butter
  • Pure Maple Syrup
  • Protein Powder

That’s it!

I have definitely tried this recipe with several other options, and can vouch for the following-

Gluten-Free Rolled Oats– You can substitute the oats for quinoa flakes or even quick oats. Be sure to add a little extra of either you use, otherwise your protein bars will be too soft. 

Almond Butter– Almond Butter can be substituted with peanut butter, sunflower seed butter or tahini

Pure Maple Syrup– For non-strict vegans, you can use honey or agave nectar

Protein Powder– Check out my shop page for all my tested recommendations. 

How to make easy protein bars

  • Line an 8 x 8-inch pan with parchment paper and set aside
  • In a large mixing bowl, combine your rolled oats and protein powder and mix well.
  • In a microwave-safe bowl or stovetop, combine your peanut butter and maple syrup and mix well, until combined. 
  • Combine your wet ingredients into your dry ingredients and mix until fully incorporated. If the batter is a little too crumbly, add a dash of milk.
  • Transfer your protein bar mixture into the lined pan and press firmly into place. If desired, top with extra chocolate chips.
  • Refrigerate for at least 30 minutes, to firm up.

When to eat protein bars

There are so many misconceptions about when is the best time to eat protein bars. Honestly, these homemade protein bars can be enjoyed any time of the day- after a workout, as a snack between meals or even several eaten for breakfast!

Storing protein bars

Homemade protein bars should be stored in the fridge, as they will remain soft and chewy the entire time. 

Refrigerated protein bars will keep fresh for up to 1 month. 

You can freeze leftover protein bars to enjoy at a later date. Wrap each bar in parchment paper and place in a ziplock bag.

Frozen protein bars will keep for up to 6 months.

  1. Agreed! It’s also hard for me to pin point my sources of inspiration. They come from..well everywhere! I just started a Pin board for no bake snacks, and I think your recipes will account for majority of the recipes pinned haha. Here’s another one to add 😉

  2. MAKING RIGHT NOW! yes I am. I told Jason I’d make him some breakfast bars and then THESE are here, so – yep, they are currently setting up in the fridge. THANK YOOOOUUUU

    1. You’re welcome my friend. I’m waiting for bloody portobello mushrooms to go down in price to start hacking at your recipes. At the moment, they are close to $5 each. EACH.

  3. Dear Arman, I know my daughter would really love these! I am going to have to share this with her. It is so easy to make too which I love. Have a wonderful day, Catherine

  4. Ew to both personal trainers and protein shakes. Ok…I sometimes add vanilla protein powder to oats or something because the almond milk I have is plain and not vanilla. I don’t think I could ever drink it with plain water 🙁 My recipes come from simple laziness. I like things to be quick and tasty. I have no problem taking help from the store and making an amazing sandwich. Sandwich ideas are what I search most frequently on Pinterest. I have made a version of these three ingredient bars before with complete success. Thanks for the idea!

  5. I can’t get over how simple these are, not to mention delicious! Can’t wait to try these out. I think these will give anyone motivation to work out 😉

  6. Yum!! I’m all about adding chocolate to bars. I think you can get inspiration anywhere and everywhere, and nope, I’ve never had a personal trainer. Do YouTube videos count? 😉

  7. These look really good, Arman! I love anything with chocolate chips, and I love that these are made with just 3 ingredients!

  8. Can’t believe how easy and healthy these are! Of course I’d probably add too many of the goodies to keep them that way 🙂 Love it!

  9. These protein bars are exactly what I need to carry with me everywhere. I am really bad about taking lunch with me, so, this would be perfect snack to have. Not to mention, they look super delicious.

  10. What you said about smoothies making you want to gag makes me all sorts of sad considering I drink around 2 or 3 a day. I’m calling off our friendship 😛

  11. I love chocolate and would definitely try this recipe, delicious!!
    For me food is the motivating factor and other two not required
