    Bring this camping classic right into your kitchen by whipping up a batch of these delicious vegan peanut butter s’mores cookies! They’re oil-free, and because they’re made with oat flour, they’re also gluten-free!

    I planned to get this recipe up before the weekend was out, but some cooking and blog projects took hold, we celebrated Mother’s Day, and before I knew it, Monday had arrived. I feel for people who couldn’t be with their moms to celebrate; I’m in the somewhat unique situation of having a longer-than-intended layover at my parents’ since the pandemic postponed my May moving plans, so I actually felt incredibly grateful to be with my mom on Mother’s Day. We had a quiet day; I made my Mediterranean Chickpea Burgers into meatballs and served them on pasta with marinara sauce and cashew parmesan, with a side kale salad. For dessert, I made my Vegan Maple Vanilla Cupcakes which I had honestly forgotten about until my friend Anna made them last week!

    Surprisingly, I haven’t been doing a lot of baking or dessert-making during the pandemic, since I’ve been living with my parents and baking is my dad’s purview. He LOVES to bake, and he loves dessert, so I’ve been leaving a lot of that up to him. It gives him something to do, and then I get to focus on developing more savoury recipes. The odd time, I have managed to fit in a dessert recipe development session, and these Vegan Peanut Butter S’mores Cookies are one of the results!

    S’mores are such a quintessential campfire recipe, but I have a feeling not too many of us will be going camping this summer. So why not bring s’mores into your kitchen by whipping up a batch of cookies with vegan marshmallows and chocolate mixed in? And while we’re at it, why not use a peanut butter oatmeal cookie base that just so happens to be oil-free, gluten-free, and not that bad for you?

    Dandies kindly gifted me a few bags of their phenomenal vegan marshmallows a couple of months ago, so these s’mores cookies are probably the first of several vegan dessert recipes that incorporate them!

    To make these Vegan Peanut Butter S’mores Cookies, you’ll:

    1. Whisk together a flax egg, smooth peanut butter, coconut sugar, maple syrup, non-dairy milk, and vanilla in a large bowl.
    2. One by one, add the baking soda, baking powder, salt, oat flour, chocolate chips, and marshmallows, stirring after each addition.
    3. Roll the dough into 16 equal balls and place them on parchment paper-lined baking sheets. Lightly flatten with your fingers. (The dough is very sticky, so use wet hands for this step!)
    4. Bake for 12 minutes and enjoy! I love serving these with a glass of non-dairy milk, but I’m also thinking that they would be positively marvelous as ice cream sandwiches!

    troubleshooting these cookies

    A few of you have shared photos of these cookies on Pinterest, and you found that the cookies didn’t spread out much. I’m not too sure why this is, because I make them regularly and they always flatten out to how they look in the photos in this post. The thing that is absolutely ESSENTIAL when making these cookies is to make sure that you roll out the dough with wet hands, because it is stickier than cookie dough made with wheat flour, and to flatten them with wet hands. 

    Also, because these are made with all oat flour, they are not going to have the same consistency as cookies made with wheat flour. Oat flour gives them a toothsome texture, which my family and I love, but might not be for everyone. So, if gluten is not an issue for you, use light spelt flour in place of the oat flour for a more traditional cookie.

    Description

    Bring this camping classic right into your kitchen by whipping up a batch of these delicious vegan peanut butter s’mores cookies! They’re oil-free, and because they’re made with oat flour, they’re also gluten-free!


    Ingredients

    Scale
    • 1 flax egg (1 tbsp ground flax mixed with 2.5 tbsp water)
    • ½ cup smooth, runny peanut butter
    • ½ cup coconut sugar
    • 2 tbsp pure maple syrup
    • 3 tbsp non-dairy milk
    • 1 tsp pure vanilla extract 
    • ½ tsp baking soda
    • ½ tsp baking powder
    • ¼ tsp fine sea salt
    • 1 ½ cups oat flour
    • ½ cup semi-sweet chocolate chips or chopped dark chocolate
    • ½ cup vegan marshmallows (I recommend Dandies brand) 

    Instructions

    1. Preheat the oven to 350 degrees F and line two baking sheets with parchment paper. 
    2. Add the flax and water to a large bowl. Whisk to combine and wait a couple of minutes for it to thicken. 
    3. Add the peanut butter, coconut sugar, maple syrup, non-dairy milk, and vanilla. Whisk to combine. 
    4. One by one, add the baking soda, baking powder, and salt, whisking after each addition. 
    5. Next, stir in the oat flour, followed by the chocolate chips and marshmallows. The dough will be quite sticky, but this is normal!
    6. With wet hands, roll the dough into 16 balls and place them on the prepared baking sheets. Lightly flatten with wet fingers. 
    7. Bake for 10-12 minutes and let the cookies cool for a few minutes before transferring them to a wire cooling rack. 

    Notes

    Any nut or seed butter should work in this recipe. The runnier the nut or seed butter, the better, though!

    This recipe was adapted from my Vegan Peanut Butter and Jam Sandwich Cookies.

      This is exactly what I was looking for before the May long weekend. I made them yesterday and we devoured all but two cookies. They were delicious! Now I have to make another batch. Fabulous.

        You might be able to! I’ve only ever made them with coconut sugar, though. If you use honey or maple syrup, you might have to add more oat flour to compensate for the additional liquid. If you use dates, you might want to blend them into a paste before adding them. Let me know how they turn out if you use any of those sweeteners! 🙂 Enjoy!

      These cookies are amazing! I followed your instructions exactly and they turned out perfect. Definitely need to wet hands when rolling the dough into balls. I love them. Will definitely make them again.

      Can I use just a regular egg in place of the fax seed egg?

        I haven’t tried using a regular egg but it should work! If the dough seems too wet, I would just add a bit more oat flour. Hope this helps and I hope you enjoy them! 🙂

      I made these tonight using runny, smooth almond butter instead of peanut butter and almond extract instead of vanilla. They were a hit for those with allergies and those without! I appreciate the recipe, thank you so much for sharing!
