These homemade protein bars are made with wholesome ingredients and naturally sweetened- they need just 4 ingredients! I love how each bar has over 21 grams of protein each!
Love high protein snacks? Try peanut butter protein balls, protein cookie dough, and protein granola bars.
I grew up eating Pure protein bars and Quest protein bars, but not anymore. Sick and tired of forking out tons of money for a store-bought protein bar, I opted to make my own and feel SO much better about it… and my wallet is thanking me too!
This protein bar recipe combines two of my favorite no bake snacks: protein balls and oatmeal energy balls. I love packing them in my bag for a quick and healthy snack between meals.

Why I love this recipe
- Made with just 4 simple ingredients, they take minutes to prepare. We try to make a batch at least once a week, so we always have some on hand. However, they taste so good, they rarely last that long.
- They use wholesome ingredients, like coconut flour, and are sweetened with just a touch of maple syrup.
- Each bar packs in over 21 grams of protein.
- They are great to enjoy between meals as they always keep hunger at bay!
Ingredients needed
- Protein Powder. Any protein powder works, including whey protein powder, casein protein powder, and pea protein powder. For flavored protein bars, why not try a flavored protein powder? Chocolate, peanut butter, and cinnamon roll are all fabulous flavors.
- Coconut Flour. This helps hold the protein bars together while ensuring they have a soft and doughy texture.
- Peanut Butter. Smooth and drippy peanut butter with no added sugar. You can also use almond butter.
- Maple Syrup. Sweeten the bars without adding refined sugar. I’ve also made these with honey and agave nectar which works well.
- Chocolate Chips. To cover the protein bars with! To keep these as plain peanut butter protein bars, you can omit the chocolate.
How to make homemade protein bars
I’ve included step-by-step photos below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the recipe card at the bottom of this post.
Step 1- Mix the ingredients. Add all the ingredients in a mixing bowl and mix until combined. Fold through the chocolate chips.
Step 2- Let the bars set. Transfer the mix into a lined pan and press down until smooth on top. Refrigerate for an hour.
Step 3- Slice. Using a slightly wet knife, slice into protein bars, then serve.
Recipe swaps and substitutions
This protein bar recipe is very forgiving and it’s easy to make them compliant to a plethora of diets out there with a few simple swaps.
- Cut the sugar. Replace the maple syrup with a sugar free maple syrup.
- Replace the coconut flour. Either oat flour or almond flour can be used instead. You may need to add a little extra flour to compensate for the extra moisture.
- Make them peanut-free. Almond butter or cashew butter are both great nut butters to use. You could make chocolate protein bars by using healthy Nutella.
- Make them nut-free. Tahini or sunflower seed butter have an almost identical texture to nut butter.
- Vegan and/or gluten free. Make vegan protein bars instead.
Storage instructions
To store: Homemade protein bars are best stored in the fridge in an airtight container. They will keep well for up to two weeks.
To freeze: Place the bars in a ziplock bag and store them in the freezer for up to 6 months.

This might be the best recipe I have ever tried.
I used pulverized Gluten Free Oats instead of coconut flour
and I used Powdered milk for the protein powder,
Trader Joes Almond butter instead of Peanut Butter
I mixed the batter up with a hand mixer, because it is a really thick dough.
I prepped a 9 x 12 glass pan by wiping it down with a couple of teaspoons olive oil.
Then I lined it with parchment paper.
I pressed the batter in as evenly as I could, but it was too thin on the edges so I folded the edges over so it was more like an 8 x 8 pan. That’s a much better thickness.
Then I used the bottom of a glass to press down evenly, but I ended up transferring the parchment and dough to the counter so I could run the rolling pin over it evenly, That worked better.
Then I sliced it on all 4 sided with a pizza cutter to make a perfect square. Save the scraps.
I pulverized a generous handful of homemade trail mix*** for a topping.
I heated the ground topping mix for 30 seconds and then pressed it evenly across the square, coated my hands with a bit of olived oil and pressed the topping into the bars, then scatter the scrap dough on top of the topping and roll across a couple of times to press it all in together.
Slice into squares with a pizza cutter, and refrigerate.
(***Trail Mix: Mixed up Trader Joe’s roasted nuts, dried fruit and chocolate chips)
Thanks so much for sharing your method, Pam- that homemade trail mix sounds SO good!!!
Seriously good protein bars!
I want to make them for my movers tomorrow but i dont have cocont flour. I have tapioca flour, gluten free flour, and walnut I could grind up to make like a nut flour. Can I use one of those and could you recommend which one? Thanks for thr recipe, it looks amazing
Hmmm I think walnut flour would work- Gluten-free flour would too, but you’d need to heat treat it first. Wait, sorry, just realized you’d made them already haha
Can we use egg white protein powder instead ?
I don’t see why not!
What flavor is this is it vinilla? or maple syrup?……
All of the photos show a “candy” type coating on the outside of the bars. The recipe does not mention this. Am I missing something?
Best homemade protein bars ever!
Made these last night. I used sugar free PB Fit and sugar free maple syrup. These taste just like the Tiger Bars I used to eat when I was a kid. So yummy!!
😀 love that, Laura!
Great recipe! Simple and delicious.
Hi! Just wondering please if you could you use a Natural Gelatin or Collagen Powder as the protein powder in this recipe? Thank you.
You could try!!
Can you use almond flour instead of coconut flour?
Yes! Just add a little more if needed 🙂
Such a simple protein bar recipe 🙂 will make again.
