Why you’ll love this recipe ..

  • Each serving of chewy bars has 11 grams of protein compared to 1 gram in store-bought.
  • Customizable to the flavors you’re craving.
  • Uses simple wholesome ingredients and no seed oils.
  • This a delicious and easy snack the whole family can enjoy!

Granola bars are one of my kid’s favorite snacks. I figured it was time for me to create something that I felt good about them eating and that the whole family could enjoy. These chewy bars are completely customizable to whatever flavors you prefer without any seed oils and high fructose corn syrup. We prefer a peanut butter chocolate chip flavor base from my Chewy Chocolate Protein Granola Bars recipe for these s’mores chewy bars but you can use almond butter in place of peanut butter for a different take on these bars. Or add dried fruit and nuts for another variation of these easy homemade granola bars. S’mores scream summer and the best part is there is no baking (or campfire!) involved making them the best snack to make during the hot summer months.

How to make these bars dairy and gluten-free

​You will need to use a dairy-free protein powder, dairy-free chocolate chips and dairy-free marshmallows. Orgain and Nuzest make a popular dairy-free vanilla protein powder. 

This recipe is not gluten-free due to the rice cereal, oats and graham crackers. However, there are many gluten-free options for cereals and oats so feel free to use one of those to make this a gluten-free granola. Simple Mills Sweet Thins would be the perfect gluten free topping her in place in graham crackers!

What you’ll need to make this chewy granola bar recipe

These are the main ingredients and substitutions. See recipe card below for full ingredients list and instructions for chewy bars.

Old Fashioned Oats: I like using Quaker but any brand with work here.

Puffed Rice Cereal: this adds a lot of volume to the bars, I get Arrowhead which is found towards the bottom shelf in a bag at my local stores. You could also use rice crisps or brown rice crisps in it’s place.

Vanilla Protein Powder: my favorite brand to bake with is Optimum Nutrition Vanilla Ice Cream. You can use your favorite brand or a dairy-free alternative. Orgain and Nuzest make a popular dairy-free vanilla protein powder. 

Granulated Sweetener: this chew bar recipe uses 1/2 cup of Stevia in the Raw. You can replace it with your favorite granular sweetener or brown sugar but to keep the calories low and protein high I opted for Stevia.

Natural Peanut Butter: use your favorite or substitute with almond butter or your favorite creamy nut butter. You can also make a PB2 peanut butter and use that instead but it will taste different and a bit artificial in my opinion.

Almond Milk: I love using unsweetened vanilla almond milk from Costco for just about everything. You can use any milk you prefer.

Lite Pancake Syrup: substitute with honey or maple syrup. Again, to keep the calories low we’re using a lite pancake syrup.

Salt: this recipes uses 1/4 tsp. of table salt but you can swap with sea salt, vanilla baking salt or whatever salt you prefer.

Mini Chocolate Chips: use dairy free if needed, regular size chips will work too but I like the mini so there’s more in every bite.

Mini Marshmallows: the key to the bars! Do not skip this part as you’ll want lots of tasty marshmallows in every bite.

Graham Crackers: you’ll need one graham cracker sheet to crunch on the top of the bars prior to placing in the refrigerator.  Any brand will do! Simple Mills Sweet Thins would be the perfect gluten free topping her in place in graham crackers!

How to make chewy bars

Prep the pan

Line an 8×8-inch baking dish with parchment paper, leaving some overhang on the sides for easy removal.

Combine dry ingredients

In a large bowl, combine the oats, puffed rice, protein powder, sweetener, and salt.

Add the wet ingredients

In a microwave-safe bowl, combine the peanut butter, almond milk, and syrup. Microwave in 30-second intervals, stirring after each, until the mixture is smooth and pourable. Stir in the vanilla extract.

Mix and add to the pan

Pour the wet ingredients into the oat mixture, stirring until everything is well coated. You will need to use a rubbed spatula to fold everything together to ensure the dry ingredients are well incorporated. Fold in 1/2 cup of marshmallows and half the chocolate chips and reserving half for the top. If the mixture is to dry add a drop of almond milk and combine. 

Transfer the mixture to the prepared baking dish, pressing it down firmly into an even layer and top with the remaining chocolate chips, 1/4 cup marshmallows and crumbled graham cracker lightly smashing into the mixture so they don’t fall off when cutting.

Refrigerate for at least 1.5 to 2 hours, or until the bars are firm enough to cut.

Cut and enjoy

Using the parchment paper, lift the bars out of the pan. Cut into 12 equal bars.

Store the bars in an airtight container at room temperature for up to a week, or in the refrigerator for up to 2 weeks. Keeping these chewy bars at room temp will help them to be less dense and chewy (my preferred method) but they’re great straight out of the fridge too. If you take one to go wrapped with parchment paper it’ll be as if you stored it at room temp.

Add in ideas!

While these bars are a great snack as is with their chewy texture and flavors, having other options is always fun! Try adding graham crackers crumbs to the mix vs. on the top, cocoa butter, dried fruit, sliced almonds, pumpkin seed, sunflower seeds, your favorite seed butter or other tree nuts.

What is the serving size for these chocolate chip granola bars?

You can absolutely weigh your final dish prior to cutting and divide by 12 to get the exact grams per serving or you can eyeball (which is what I do!) and cut it into 12 equal slices and enjoy.

While these bars are almost 100 calories more than the storebought brand you’re used to these have 11 grams of protein compared to 1 gram! See the recipe card below for the full nutrition information.
