My family loves my homemade protein bars so much so, I make them weekly. To change things up, I like to give them a little flavor spin and change up the base recipe with some fun variations. These include cookies and cream protein bars, pumpkin protein bars, and s’mores protein bars.

Ingredients Needed

These delicious snack bars are made with nutritionally dense ingredients and a couple of indulgent elements (smores and chocolate chips)! Here’s what you’ll need.

  • Oat flour. Make your own oat flour using this simple recipe. Or you can get one in your regular supermarket.
  • Coconut flour. You can get this versatile flour in any grocery store these days. Sift it before use to remove any lumps.
  • Protein powder. Use your favorite protein powder. My go-to choices are generally chocolate or vanilla flavor protein powder as they go seamlessly with the this particular flavor. 
  • Granulated sweetener. Optional, but I like to add some coconut sugar or a sugar substitute (like allulose). If your protein powder is super sweet, you can omit this.
  • Graham cracker crumbs. You get the perfect textural variety with these cracker crumbs. To make it at home, you can either pulse them on low in the processor or beat them out with a roller.
  • Almond butter. It adds a fantastic flavor, healthy fats, and nuttiness to these healthy protein bars.
  • Brown rice syrup. Or any liquid sweetener of choice. I sometimes use honey or agave nectar.
  • Milk. To bring the bars together. I used unsweetened almond milk but use whichever milk you have on hand.
  • Mini marshmallows. The star ingredient! Mini marshmallows are more evenly dispersed than the larger ones.
  • Chocolate chips. Use milk, dark, semisweet, white, or a mix of different dairy-free chocolate chips.

How to make S’mores protein bars

While classic s’mores may not be the healthiest diet choices, these s’mores protein bars are super-tasty and filling snacks.

Step 1- Mix the dry ingredients. Combine dry ingredients like oat and coconut flour, protein powder, crushed Graham crackers, and granulated in a bowl.

Step 2- Make the protein bar mixture. Melt almond butter with the liquid sweetener in a microwave and pour it over the dry ingredients. Mix it until combined, and if crumbly, add milk to bring the batter together.

Step 3- Make protein bars. Once you have a thick batter, add chocolate chips and mini marshmallows. Transfer the mixture to a large dish lined with greased baking paper and press it firmly.

Step 4- Refrigerate and enjoy. Allow the slab to firm up inside the refrigerator for at least 30 minutes. Once set, slice, and enjoy!

Recipe tips and variations

  • Use the right protein powder. Your protein bars are only as good as your protein powder! Stick to the flavors you like and buy unsweetened casein or plant-based protein powders to make these bars.
  • Adjust the thickness. I prefer my protein bars to be slightly thick. For thinner bars, go for a larger baking tray.     
  • Check the consistency of the batter. If the batter is too crumbly, add more milk to adjust the consistency of the mixture. You want it to be thick, dough-like.  
  • The gourmet appearance. Sprinkle some sea salt or drizzle melted chocolate or granola butter over the bar, and enjoy it in peace!

Storage instructions

To store. S’mores protein bars keep well at room temperature for a week in a sealed container. To enjoy them for long, refrigerate them in airtight containers for over a month.

To freeze. You could also freeze them in freezer-safe bags for up to six months.

Frequently asked questions

Are marshmallows vegan?

Marshmallows often contain gelatin, a protein sourced from animals. So, if you follow a vegan lifestyle, buy plant-based marshmallows to make this recipe.

Are s’mores protein bars healthy?

With healthy and nutrient-dense ingredients like oat flour, nut butter, and protein powder, these s’mores bars will fulfill your protein requirements. For a low-calorie option, substitute the sweeteners with sugar-free alternatives.

Are these protein bars healthier than Quest protein bars?

Certainly! The store-bought ones are highly processed and loaded with artificial flavors and sweeteners. Often, they don’t contain enough protein either. That’s why making your protein bars at home is a cheaper and healthier alternative.

    Well, with the recent studies coming out – the sucralose and erythritol “bad news” “white papers” that gloss over the news links every morning, my husband started panicking , as we are Quest junkies. We LIVE on them. This is going to be a fantastic alternative – not to mention SO MUCH CHEAPER – GAH! My Quest bill monthly, for two people who exercise 1-2 hours a day (protein goals of him, 180 g per day and me, 100 g per day) is OVER $250. This will be a nice shift in money. Not to mention – using natural, whole ingredients that won’t become genotoxic once metabolized or cause a heart attack down the line is a huge plus. Phew!

    Personally, I wonder who PAID for those studies. It is always wise to remember that in the 60-70s, the sugar industry SECRETLY paid for a study from HARVARD that said sugar was NOT implicated in obesity and heart disease. That you need to worry about fat… Someone found that study in the early 90s and it went viral again – hence the birth of low fat snacks like Snackwells and all other pseudo low fat, olestra laden foods. Sheesh.

    Yeah – I will definitely be making these bars.

  2. Thanks so much for this recipe. I work with families and am going to test this recipe out on kids in an attempt to help give parents ideas for healthier snacks this summer! Question for you – how long do these bars stay good for? Do you just keep them in the fridge? Do they freeze well?

    1. Hi Jalene!

      That sounds like a fantastic idea- I hope you guys enjoy them! I usually keep them frozen (individually wrapped) for up to a month, sometimes 2 months. Refrigeration wise, they are great for a week, especially if you top them with marshmallows, instead of mixed through.
