Why Eat Protein Bars?

It can be challenging to meet our protein needs for some individuals. Depending on your nutrition goals (if you want to lose weight or gain muscle), the level of activity you participate in (sports or exercise), if you’re pregnant or breast feeding, these will all increase your protein need. To help fill in the protein need gap, consuming protein bars can help you to meet your goals. I like to eat these instead of a sugary dessert like a cookie as it fulfills my sweet tooth and has more protein.


Chocolate Chips:
You can use what ever kind of chocolate chips you prefer. I love gharadelli personally, but have used store-brand or costco bulk brand before to save on costs.

Peanut Butter:
I used natural, creamy peanut butter. I’m sure a chunky peanut butter would be delightful in this recipe and give more of a “snickers bar” feel.

I used gluten free bob’s red mill, but any rolled oat will work or oat flour.

Maple Syrup: Opt for pure maple syrup as a natural sweetener for this recipe because of the additional nutrients it provides like: riboflavin, zinc, magnesium, calcium and potassium.

Milk: I used 2% milk because it’s typically what we have on hand. To make this recipe dairy-free, opt for soy milk or almond milk.

Vanilla Extract: Vanilla extract helps to bring out the natural flavors of this recipe and heighten the sweetness. It is optional because we’re not baking it, so choose what flavor you want.

Vanilla Protein Powder: I used Vega Vanilla protein powder and I opt for the stevia-free versions typically as I have a sensitive belly. You could opt for the stevia version of this protein powder if you are looking to further reduce the sugar in the recipe. However, what ever protein powder you get I would ensure it’s third party tested.

How To Make Chocolate Peanut Butter Protein Bars

To make these protein bars you will want to prepare an 8 x8 pan with cooking spray or butter (I used avocado oil spray). Then you will want to blend your rolled oats into a flour using the blender. Combine the first 6 ingredients (peanut butter, oat flour, vanilla extract, maple syrup, milk and protein powder) in a kitchen aid mixer or by hand until well combined and forming a “dough”. Finally, combine chocolate chips and coconut oil in a microwave safe bowl, heating for 30 second increments until melted and stirred easily. You’ll layer the oat mixture into your 8×8 pan and then pour the melted chocolate on top, spreading evenly. Stick the 8×8 pan into the freezer and freeze for 3 hours or over night. Cut the bars into squares and enjoy!

What’s The Best Protein Powder To Use?

The best protein is one that you enjoy the taste of. Seriously, there are so many types of protein supplements out there and as someone who regularly consumes protein powder I can be quite picky. As I mentioned above I usually stay away from artificially sweetened protein powders for tummy related side effects, and I opt for a protein powder that has been third party tested by NSF sports. This helps to ensure that there is nothing in the protein powder that isn’t supposed to be there.

How To Store?

I cut these into squares and then put them into a freezer-safe tupper ware container and put them back into the freezer. They stay good for up to 3 months, however we always eat ours within a week.
