These no-bake peanut butter protein bars are made with simple ingredients and super easy to whip up. They’re an awesome protein-packed snack to meal prep for the week.

I always try to eat protein with each meal and snack. There are some quality store-bought snacks that are high in protein, but a lot of protein bars at the grocery store are loaded with questionable ingredients.

That said, one of my favorite store-bought protein bars are perfect bars. They have a ton of different flavor variations and are made with real ingredients. My favorite flavor variation is dark chocolate peanut butter (obviously!), so I took it upon myself to make a homemade version.

And if I do say so myself, this homemade version tastes just like the real deal! They seriously taste like dessert, but are packed with protein and made with minimal, nutritious ingredients.

Protein Bars vs. Granola Bars

There are a few differences between these protein bars and my granola bars. The obvious difference is that these have protein! I mixed in some vegan protein powder to make these more filling. These also seem a little bit denser to me compared to the granola bars. They’re almost like protein balls in bar form where as the granola bars have more texture and seem a little lighter to me. You really can’t go wrong, both recipes are on regular rotation in our house, it just depends on what we’re in the mood for!

Ingredients measured out to make protein bars: honey, oat flour, protein powder, peanut butter, salt, vanilla, chocolate chips and coconut oil.

Here’s What You Need

  • vanilla protein powder – any vanilla protein powder works. My favorite brand is Nuzest which is plant-based and has a minimal, clean ingredient list. You can use my code eatingbirdfood for 15% off your order.
  • oat flour – make your own by grinding rolled oats or buy store-bought oat flour. Make sure to grab gluten-free if needed.
  • salt – omit if peanut butter has salt.
  • natural creamy peanut butter – you want to use natural, drippy peanut butter not a thick peanut butter spread. I usually go for the store brand and read the label to make sure it just one or two ingredients, the nuts and salt. Any natural creamy nut butter will work. Almond butter or cashew butter would be great options.
  • honey – this natural sweetener holds the bars together and gives the bars a subtle sweetness. I haven’t tested this recipe with anything else, but I think another liquid sweetener like maple syrup or date syrup would work well. 
  • coconut oil – you want it to be in it’s liquid state when you measure so heat it for a bit if needed!
  • vanilla extract – a delicious flavor enhancer.
  • chocolate chips – I recommend Lily’s chocolate chips because they have zero sugar added.

Are Protein Bars Good For You

Protein is a super important macronutrient to consume and many people find it hard to meet their protein goals without supplementing with protein products like protein bars. I personally think it’s best to get your protein from whole, real foods when possible, but protein bars are a great option when needed. And they can help with weight loss because they can keep you feeling full and satisfied between meals and prevent mindless snacking.

Of course, you can buy protein bars at the store, but I really like making my own so I know exactly what’s in them. There are some protein bars on the market that really aren’t much better than a candy bar… loaded with artificial sweeteners and preservatives. These homemade bars have 12 grams of protein and they’re made with simple whole food ingredients!

When to Eat Protein Bars

These protein bars could be a breakfast replacement if you don’t have time for a full meal or are a great snack option. I like to have one as an afternoon snack… you know, when that 3:00 PM hunger rolls around! But they’re also a great post-workout snack as well. The protein helps repair and rebuild your muscles!

How to Store

One of the best things about these bars is that they store really well! I love making a batch every couple of weeks so I have healthy, protein-packed snacks ready to grab. After the bars have set, store in an airtight container in the refrigerator for 1 week or in the freezer for up to 3 months. I like to store them in single portions so they’re ready to grab and go! If you do freeze them, just thaw in the fridge before enjoying.

    These are divine and took me no time to make! I had to substitute the oat flour for 1/2 gluten free flour and 1/2 almond meal because of what I had on hand and they turned out great! They were so easy to make and delicious!
