Sea Salt Cashew Butter Chocolate Protein Bars

I constantly have a supply of proteins bars (omg GoMacro is my long time fav) but sometimes it’s fun to make your own! Not only are homemade protein bars easy to make, but they’re also an amazing, inexpensive alternative to buying protein bars.

These simple yet oh-so-delicious cashew butter chocolate protein bars are made with plenty of pantry staples and your go-to protein powder. The result seriously tastes like dessert, so you’re gonna want to keep some in the fridge for when that sweet tooth hits!

Post-workout, post-dinner or even lunch dessert — make a batch of these babies and get ready to devour.

I hope you love keeping these bars in the fridge and enjoying them as a snack or treat!

Everything you’ll need to make these chocolate protein bars

These easy no bake cashew butter chocolate protein bars are made with plenty of pantry staples and a boost of protein from your fav protein powder. Here’s everything you’ll need to make them:

  • Cashew butter: I love using cashew butter because it’s mild and really allows the chocolate flavor to come out.
  • Coconut oil: a little coconut oil helps to keep the bars together and adds additional flavor. There is no substitute (except butter) so please don’t ask me for one!
  • Honey: I like to use honey to sweeten the bars a bit. You’ll also need a little vanilla extract.
  • Rolled oats: some rolled oats add a complex carb to the protein bar. You can use gluten free oats if desired, but do not use steel cut oats as the texture will be gritty.
  • Chia seeds: get a boost of omega-3 fatty acids, fiber and antioxidants from chia seeds.
  • Protein powder: I want to recommend my favorite chocolate protein powders for you. I use Aloha Plant Based protein powder in most of my baking recipes. Another great one is Tera’s Whey Chocolate. Please let me know if you use any other chocolate protein powders that you recommend in the comments section!
  • Dark chocolate: the dark chocolate adds a double chocolate dose of love to the bars so don’t skip it! Feel free to use 1 ounce of an 85% dark chocolate bar or a few tablespoons of chocolate chips (dairy free if desired).
  • Sea salt: a little sprinkle of sea salt on top takes these bars to the next level.

Easy ingredient swaps

Because these healthy chocolate protein bars are made with simple ingredients, they’re easy to customize with what you have on hand! Here’s what I can recommend:

  • To make vegan: feel free to use brown rice syrup or coconut palm syrup in place of the honey. Then be sure to use a plant-based protein powder as well as dairy free chocolate on top.
  • For the cashew butter: I love the mild taste of cashew butter in these bars, but you can also use peanut butter, almond butter, or even sunflower seed butter for a nut free alternative! Just be sure the nut or seed butter is all natural and is just made with nuts or seeds and salt.

DIY chocolate protein powder

If you don’t have chocolate protein powder on hand, you can mix 1/2 cup of your favorite vanilla protein powder with 2 tablespoons of cacao or cocoa powder. So easy!
