Today I’m working with Bob’s Red Mill! If you didn’t know, I’ve been working with them on bringing you recipes for 3 years now. I buy their products regularly; I love this company and all that they do and sell. Thanks for enjoying a recipe they help make possible.

Ingredients needed in healthy snack bars:

  • Peanut Butter: use the natural drippy kind that’s made with just peanuts and salt. It mixes together great and helps everything to stick together.
  • Honey: this is what makes the recipe sweet. We just harvest our honey (15 gallons!!) and I love using the raw honey to sweeten things. Shop local for honey if you can!
  • Protein Powder: lots of options here, Bob’s Red Mill has a new almond protein powder that I’m excited to try. I’ve also used their pea protein for this as well as collagen peptides. You can use vanilla or unsweetened, or feel free to try anything else you like or have.
  • Flax Seed Meal: this stuff is packed with protein and fiber and I love it. This is ground flax seed, called flax meal.
  • Chia Seeds: these little seeds are packed with all kind of nutrition too and they are great at helping your bars stick together.
  • Quick Cooking Oats: I love the complex carbohydrates these add and quick cooking oats have the best texture for this recipe.
  • Shredded Coconut: this add a little texture. Look for unsweetened.

Substitutions for this recipe:

  • If peanut butter is an issue feel free to sub it for any other nut or seed butter as long as it’s a natural drippy nut butter that has a similar texture as peanut butter. Sun butter would also work well here.
  • You can sub maple syrup, agave, or brown rice syrup for the honey if you’d like. If using one of these consider adding 1/4 cup more oats to help absorb some of the liquid from the thinner sweeteners.
  • You can use whatever protein powder you like or have on hand. Bob’s Red Mill has some good ones if you are looking for them. I generally go for unsweetened and unflavored, but I bet a vanilla protein powder would be amazing here.
  • You can change around the chia seeds and flax meal if you like, but they both help this recipe stick together. You can replace them with something like hemp seed hearts but add more oats to help things stick together.
  • Don’t want to add the oats? You can leave them out and replace them with coconut.
  • Don’t love coconut flakes? Replace them with more oats.
  • I am happy to help you make substitutions, just leave a comment and I’ll get back to you.

Frequently asked questions:

What are the healthiest snack bars?

I think it’s the ones that you’ll eat! LOL, if you don’t like them, they don’t taste good, or you can’t read the ingredients, why buy them? That’s the perk of making your own, you can pick what you like, adjust the flavors to your preferences, and make them with things you love!

Is it ok to eat 2 protein bars a day?

For this recipe, yes! These aren’t traditional “protein bars” and it’s A-OK to eat what your body says is a good amount in a day. My kids love these and I love these for a little snack in the afternoon or when I get the munchies in the evening. The serving size for this recipe is actually to “bars” or small squares, so by all means, eat two!

What’s your favorite Bob’s Red Mill product?

This feels like choosing a favorite child! BUT there are some that I use a ton and here’s my quick list. I buy their organic all purpose flour in 25 pound bags (it’s the best for sourdough bread!). I love all of their oats, they have a great medium grind cornmeal, their unsweetened coconut (flakes and shredded) are so good, and their oatmeal cups are my favorite breakfast to throw in my bag while traveling. I basically love everything they do though 🙂

  • Line an 8×8 inch baking dish with parchment or waxed paper. Leave some over hang with the paper on each side of the pan so that it’s easy to pull the bars out of the pan later. Set the pan aside.
  • In a medium mixing bowl add the honey, peanut butter, and coconut oil and stir to combine.
  • Add the protein powder, flax meal, chia seeds, shredded coconut, and oats. 
  • Stir to combine.
  • Place the peanut butter mixture into the prepared pan and press it into the bottom of the pan.
  • Melt the chocolate chips and the coconut oil together (microwave and stove top both work for this) and then spread the melted chocolate over the peanut butter layer
  • Sprinkle the melted chocolate with a little coarse sea salt if you’d like (optional).
  • Place the bars in the fridge until they are firm, about 1 hour.
  • Remove from the pan and place on a cutting board. Cut into 16 snack bars. Store bars in the fridge.


  • If you are leaving out the oats, reduce the coconut oil to 1 tablespoon.
  • These have a better texture and store the best if kept in the fridge.
  • See post for details on substitutions for this recipes. It’s very flexible!
  • You can make these bars in a 9×5 bread pan if you’d like the bars to be thicker, it works great.

    Just made this today for an outdoor snack and it was a hit with the kids and adults!!! Definitely saving this recipe for future use. I didn’t have any coconut flakes on hand (not a hug coconut fan) and the recipe still tasted great without!
