Peanut Butter Protein Bars

What is my favourite nut butter flavour? This is one of the hardest questions because I absolutely LOVE nut butter! But if I had to pick only one flavour it would have to be either chocolate hazelnut or peanut butter! Yes, I know that’s two- but hopefully i’m forgiven!

I don’t often eat protein bars, just because most store bought varieties have a strange texture, or artificial sweetener taste! I also prefer to eat whole meals, but lately I have been feeling like a sweet treat that has an extra protein kick! These peanut butter protein bars are exactly that, and super easy to make!

No-Bake Homemade Protein Bars

Now there is just something I have to say that is ESSENTIAL for any of my protein recipes. That is that you HAVE to LOVE the taste of your actual protein powder! If you’re using the protein powder in you’re baking then your baked goods WILL taste like your protein powder- so pick a tasty one!

Reese’s Peanut Butter Bars

With Easter just passing, I tried my first ever Reese’s peanut butter egg for the first time! All I can say is that it was absolutely delicious and my mind was blown! But it got me thinking, is there any way to make this higher in fiber, lower in sugar and higher in protein? So, this idea was born! Honestly, I haven’t been able to stop having them as my afternoon snack! The perfect pick me up that keeps me full until dinner!

Peanut Butter Replacements

Now I know there will be a select few who do not like peanut butter, or want to know if they can use any replacements. You could replace the peanut butter with any nut/seed butter of choice! They work especially well with almond butter, hazelnut butter and even cashew butter!

How do you make the peanut butter protein bars

The Ingredients

Oat flour- I make my own by blending oats into oat flour

Nut/seed butter of choice- Use any nut butter/seed butter if choice! My personal favourites are peanut butter or hazelnut butter

Protein powder- Vanilla protein powder of choice

Granulated sweetener of choice- I like to use monk fruit or erythritol but any granulated sweetener or sugar will work.

Chocolate of choice: Dark or milk works best! 

Almond Milk- You can use any milk of choice but my preference is almond milk



Combine all ingredients above in a bowl. Roll into desired shape.

  • cup vanilla protein powder OR almond flour 118g
  • 3-4 tbsp granulated sweetener of choice
  • ½ cup peanut butter or nut butter of choice 129g
  • ½-1 cup milk of choice Depending on your protein powder! Whey protein needs less water, and pea protein needs more. Slowly add your milk until you get a nice dough that you can roll with your hands.
