The day is FINALLY here…I am finally sharing the recipe for these vegan peanut butter s’mores bars! If you follow along on my Instagram page, then you know this recipe has been completed for a while now, but the store we grocery shop at stopped carrying vegan marshmallows, so I couldn’t get my hands on them for a while to take photos.

Thankfully, I found them elsewhere, was able to take my photos and video and we are ready to go! So, I now introduce you to the most delicious vegan peanut butter s’mores bars.

These bars are vegan, gluten-free (see notes below under ingredients), oil-free and made with minimal ingredients, and the additional of peanut butter just takes them NEXT LEVEL. They are made in one bowl with oat flour, sweetened with unrefined coconut sugar and are packed with so many bites of melty dark chocolate and gooey marshmallows. After they come out of the oven, they are cooled, sliced and topped with graham crackers for that perfect crunch. I have made these for so many people and they are a total crowd pleaser!

Ingredients in Vegan Peanut Butter S’mores Bars

Natural Peanut Butter– use peanut butter without any added oils or sweeteners- you want to look for one that is organic and contains only peanuts and salt.

Oat Flour– to keep these bars gluten-free, I pulse gluten-free rolled oats in my blender until an utra fine and soft flour forms. Also feel free to buy packaged oat flour.

Coconut Palm Sugar

Vanilla Extract

Plant-Based Milk– you can use any plant-based milk you have on hand.

Baking Powder

Baking Soda

Pink Himalayan Salt

Dark Chocolate Chips– I use this brand that is vegan.

Mini Vegan Marshmallows– make sure to use mini marshmallows. If you can only find large vegan marshmallow, you can break them up into smaller pieces.

Graham Crackers– to top the bars with. To ENSURE that these bars are vegan and gluten-free, make sure to find vegan and gluten-free graham crackers!

How to Make

Start by preheating the oven to 350 degrees F. Line an 8×8 baking dish with parchment paper and set aside.

In a medium bowl, add the wet ingredients: natural peanut butter, coconut palm sugar, vanilla extract and plant-based milk. Whisk very well.

Next, add the dry ingredients (minus the chocolate chips and marshmallows) to the bowl: oat flour, baking powder, baking soda and mineral salt. Mix well with a spatula.

Then, fold in the vegan chocolate chips and mini marshmallows.

Add the batter to the prepared baking dish, top with more vegan marshmallows and chocolate chips (gently press the marshmallows into the batter), and bake on the center rack for about 23 to 25 minutes or until a toothpick inserted comes out clean. I use a glass dish- if you are using a darker metal pan, check on these bars sooner because they will bake quicker in a metal pan.

Let this cool for a while in the pan (about 30-40 minutes), then slice into bars and top with graham crackers right before serving. It is very important to make sure the bars have cooled before you slice them as they are very fragile when hot. Don’t worry, the marshmallows will stay nice and soft!

I like to store these covered on the counter so they stay super soft, but you can also store them in the fridge. Enjoy!

Tips for Making the Best Vegan S’mores Bars

-Use natural peanut butter and make sure its soft and drippy for the best texture

-If you are pulsing your own oats for oat flour, be sure to pulse until the oats are soft, fluffy and super fine.

-Use parchment paper to line your baking dish for easy removal

-Use mini vegan marshmallows and not the regular ones. If you can’t find mini vegan marshmallows, you can break large marshmallows up into smaller pieces.

-Make sure to let these cool before slicing as they are very fragile when hot.

FAQ

Can I use another sweetener?

You can try as long as its granulated. Do not use a liquid sweetener. Brown sugar would most likely work.

What if I have a peanut allergy?

You can use almond butter!

How long do these stay fresh for?

I keep mine covered on the counter for a few days, or you can keep them covered in the fridge for 4-5 days, although I doubt they will last that long!
