Triple Peanut Butter S’mores Bars with peanut butter, peanut butter powder and peanut flour too! An easy, healthy and high protein PB S’mores bars recipe for your next snack.

These Peanut Butter S’mores Bars are the perfect blend of comfort and indulgence, bringing together the best parts of your favorite campfire treat with the rich flavor of peanut butter. They’ve got no chocolate, and have a rich pb flavor instead, so great for anyone who isn’t a fan of chocolate or has allergies.

What makes these PB S’mores Bars healthy

  • No Butter: Unlike most baked cookie bars, these pb smores bars have no butter! Just a big of peanut butter for the rich flavor and healthy fats too.
  • No Eggs in here, so quite easy to make Vegan if you need!
  • Gluten Free: I actually used a 1:1 gluten free baking flour here, so I know for certain that this recipe is great for GF!
  • No Diary! Since there’s no chocolate in this recipe and no milk either (just almond milk), you have a great dairy free s’mores bar recipe!

Ingredients for Healthy Peanut Butter S’mores Bars

These healthy peanut butter s’mores bars are made with a healthy ingredients like protein powder and peanut butter powder and have no extra sugar or fats that you don’t need already.

  • Vanilla Protein Powder needed for high protein peanut butter s’mores bars, and provide sweetness to these bars.
    I used whey-casein Vanilla protein powder from Quest Nutrition.
  • Peanut Flour like this one from PbFit.
    You can also replace this with 30g Flour + 14g Peanut Butter Powder.
  • Flour – I used 1:1 Gluten Free Baking Flour, but would also recommend Whole Wheat Pastry Flour or All Purpose Flour
  • Peanut Butter Powder, also known as Powdered Peanut Butter. I recommend PbFit.
  • Creamy Peanut Butter – I recommend anything from ADNB since they are extra high in protein and have delicious flavors too!
  • Unsweetened Applesauce
  • Unsweetened Almond Milk
  • Nonfat Plain Greek Yogurt
  • Baking Soda

And then for the s’mores effect:

  • Marshmallow Fluff
  • Graham Crackers

How to make Peanut Butter S’mores Protein Bars

These peanut butter s’mores protein bars are really easy to put together! Here’s what it takes:

  1. Whisk dry ingredients – flour, vanilla protein powder, peanut flour, peanut butter powder, baking soda.
  2. Whisk wet ingredients – applesauce, yogurt, milk and peanut butter.
  3. Add wet mix into dry mix and whisk to combine.
    Don’t over-mix the batter!
    Make sure you gently fold the dry mix into the wet to combine them.
    If you over-mix it, the protein powder will make the healthy peanut butter smores squares tough, dense and gummy.
  4. Taste the batter and see if you need some extra sweetener. I’d recommend using stevia powder to maintain the consistency of the batter and have low sugar peanut butter s’mores dessert recipe.
  5. Grease and line 8×8” baking pan with parchment paper to prevent bars from sticking to pan.
    Arrange graham crackers on bottom of pan.
  6. Pour half the batter into the baking pan and spread evenly.
    Add dollops of marshmallow fluff on top, and remaining batter.
    Smoothen our.
  7. Bake 25 minutes at  350°F.
    Remove when toothpick/tester comes out dry with only few crumbs. Bars will overcook and harden otherwise.

How to store PB S’mores Bars?

Whether you’re bringing these PB S’mores to a party or meal prepping them for a snack during the week, make sure you store them well so they remain fresh as long as possible.

Store protein fluffernutter bars in an airtight container in the fridge for a week.

You can also freeze these peanut butter s’mores protein bars in a freezer-safe zipper bags or air tight container; The peanut butter smores bars should keep for 2-3 months.

Alternatives for Peanut Butter S’mores Bars Recipe

I made these high protein peanut butter s’mores bars recipe with the ingredients and specific brands I mentioned, but here’s some alternatives you can try.

I haven’t testing them all so I can’t say how your recipe might turn out. I’d love to know if you do!

  • Flour: All purpose flour, 1:1 gluten free baking flour or Whole Wheat Pastry Flour all work here; Use the same amount by weight
  • Peanut Flour: You can replace this with 30g Flour + 14g Peanut Butter Powder.
  • Peanut Butter Powder: Instead, use 3 tablespoon Peanut Butter, nut also reduce milk to 65ml.

    This is probably the 5th or 6th recipe that I’ve tried and once again I’m LOVING it! The crumb on all her cakes is always spot on while being macro friendly enough for me to have desserts while on a cut!! I did end up making only the cake (I love peanut butter) because of that whole cut thing but it didn’t matter because the cake is soooooo good…I can imagine how crazy good it’ll be when I make it with the fluff and grahams!

      You just made my day Jody! I’m so so happy you loved this recipe.

      The peanut butter base recipe really is so good even without the mix-ins so I know you’re gonna love it even more when it has the full s’mores effect!
