Walnut Oat Cookie Bars

November 4, 2019 by Mia Zarlengo 14 Comments

These little bites of heaven only require 5 main ingredients.

They are so simple and SO delicious. I’m officially addicted- and I promise you will be too. A new staple in my kitchen!

They’re vegan + gluten free, and you would seriously never know! I think they taste like a bakery style cookie- but they are SO easy to make and a bit healthier ;). You can load them up with chocolate chips, or you can spread them with melty chocolate like I did here. Both ways are absolutely delicious!

I love having something sweet around made with staple ingredients. The oats combined with the nutty walnuts just gives these little squares the best flavor.

Enjoy! xx

Description

Soft, gooey, nutty walnut oat cookie bars. The best gluten free and vegan treat!


Scale

Ingredients

  • 1 cup gluten free old fashioned oats
  • 1 cup raw walnuts 
  • 1/4 cup pure maple syrup 
  • 2 tbsp avocado oil 
  • 1/2 tsp sea salt 
  • 1/4–1/3 cup mini chocolate chips (or for a melty chocolate topping seen in the photos- use 1/3 cup chocolate chips and 1/2 tsp coconut oil melted in the microwave or stovetop)

Instructions

  1. Preheat oven to 350°F. Add oats, walnuts, and sea salt to a food processor. Pulse for 15-20 seconds, until a meal forms. 
  2. While processor is still on, pour in maple syrup and avocado oil. Process until a dough forms. This should take 1 minute or less. 
  3. Spread dough onto an 8×8 square baking dish lined with parchment paper. Be patient- it will take a minute to spread the dough evenly. Tip: make sure to keep an inch or 2 of the baking dish unfilled on all 4 sides so that the bars are not spread too thin. I use a small spatula to shape the dough into a square about 1/2 inch thick.
  4. Sprinkle chocolate chips over the top (or if you want the melty chocolate topping, save that for after the bars are baked and cooled) . Bake for 11-12 minutes, then immediately lift parchment  paper up to remove bars from the baking dish. Allow to completely cool, then slice into 12 squares. Note: if you don’t allow the bars to cool before slicing, they will be very fragile!

Notes

I do not reccommend substituting a different nut here, or using aluminum foil in place of parchment paper!

    This was the first thing I ever made from Mia’s recipes and they 100% sold me. They’re incredibly easy for an easily aggravated baker such as myself.

    EASIEST dessert recipe. Took me less than a half hour. I didn’t have a food processor, but it worked relatively well with a blender. I brought it in for work and they were gone within minutes. I will definitely be making this again perfect for last minute treat to when going to a friends house.

    So good! Made these over thanksgiving and everyone couldn’t believe how easy and clean they were. Listen to Mia’s tip and let them cool awhile before cutting. I used a vitamix and consistency worked well.

    I make these every. single. week. and bring them to work. They’re the best. Have gotten me through so many afternoons of hunger at work. I have became infamous for them and my snack drawer was getting so raided that my boss had me start keeping them in her office so people wouldn’t eat our stash. The best snack ever.

    Also, I am allergic to nuts, so I just make with a double serving of oats. Also, don’t let the chocolate top intimidate you, I make these with just chocolate chips and not that full coat of chocolate on the top. I also put the chocolate chips in my food processor while mixing up the oats/syrup/oil and then add more on top at the end. Also, using pure maple syrup makes a BIG difference. Yes, it’s more expensive but tastes way better.

    I’ve made these a couple of times and got so many compliments! Such a nice change using walnuts instead of bananas or lots of flours for bars.

    Since we’re stuck in the house for a while I’ve been finding myself wanting to cook and bake more. I saw these bars and had all ingredients in my pantry so I gave it a go and WOW do those 5 little ingredients pack a PUNCH. Can’t wait to bring these to my next girls night. Thanks Mia!

    Our go-to quick and easy dessert. We keep them in the freezer! Subbed hazelnuts when I didn’t have walnuts- they still turned out great.

definitely not here to brag about my summer roll w definitely not here to brag about my summer roll wrapping game (🥲), BUT you do need this spicy almond butter sauce in your life!! this is one of my weekly go-to meals. i use whatever i have on hand- these have butter lettuce, shredded cabbage, bell pepper, and air fried tofu. so perfect!! you can also make the sauce nut free with sunflower butter- link in bio for the recipe! 

for the tofu:
press out liquid, slice into strips, and spray with a little avocado oil. season with any seasonings you like, then air fry at 400 for 10 mins or so until crisp. they will puff up a lot but deflate once out of the air fryer!
