Gluten-Free Vegan Walnut and Oat Brownies

Gluten-Free Vegan Walnut and Oat Brownies | The Healthy Family and Home

Although I thought I’d never stray from my Flourless Zucchini Brownies that I make very frequently, these Gluten-Free Vegan Walnut and Oat Brownies I came up with are pretty hard to pass up.

It’s another chocolate, gluten-free and vegan treat I can enjoy without any guilt and will easily satisfy a brownie craving…especially when they are covered with the thick raw cacao topping.

Even though the rest of my family doesn’t necessarily need to eat gluten-free, I don’t like making desserts for them using white flour, even though when I do, I buy organic, unbleached white flour.

I like that I can make them brownies that are healthy and that doesn’t use any flour at all.

Here are the typical ingredients found in a traditional homemade Walnut Brownie recipe (the boxed versions are even worse):


S.A.D. Standard American Diet Walnut Brownie Ingredients:




In summary, that’s 2 1/3 cups of refined sugar, 1/2 cup of butter and it contains white flour, milk and eggs.

This healthier version is flourless, vegan, gluten-free, dairy-free, egg-free and contain no refined sugar.

Where to Buy:  If you have trouble finding any of the ingredients to make this recipe, you can order online from Amazon and have them delivered straight to your door!



Tip #1:  The second step in the recipe isn’t necessary, but one that I prefer.  Instead of using the large, whole pieces of oats (which makes the brownies extra crunchy, almost like having coconut flakes in them), I put them in the food processor and lightly pulse them to break them down into smaller pieces (approximately 20 – 25 long pulses).  I also add the dates (pitted) when I do this because it helps break them into smaller pieces too, as opposed to dicing them by hand.

You have to be careful though, to not over process the oats because they will turn into oat flour.  So in trying to prevent this from happening, the dates may not get processed into tiny enough pieces.  Just take them out and cut the larger pieces of dates into smaller pieces.  It also helps to process them with the oats because they get a little powdering coating on them (from the oats) and they aren’t as sticky to handle when trying to cut them.

Tip #2:  When making the chocolate frosting, you need to find a medium with the coconut oil.   You don’t want it to be completely liquid/melted (it will be too thin and not like a frosting) and you don’t want it to be completely solid (it will be too thick and not spread) but somewhere in the middle, like soft and semi-melted.  You will know when it’s right because it will either be too thick or too thin otherwise.  But it should have a similar consistency of traditional frosting and spread easily on the brownies with a knife.

Tip #3:  Try to keep an eye on them in the oven.  If you want them to be more of a chewy texture, don’t leave them in as long.  If you want more of a harder, crunchy, cookie-like texture leave them in a little longer, just taking care they don’t burn.

Tip #4:  Make sure the brownies have cooled ~completely~ before adding the icing.  The heat from the brownies will melt the coconut oil in the frosting and it will become runny.  And keep them in the refrigerator too or the same thing will happen if they are left out at room temperature and the icing gets too warm.


Gluten-Free Vegan Walnut and Oat Brownies (Vegan, Gluten-Free, Grain-Free, Flourless, Dairy-Free, No Refined Sugar) The Healthy Family and Home


For the brownies

  • 1/2 cup organic raw cacao powder
  • 4 tablespoons organic coconut oil (melted/liquid)
  • 3/4 cups organic quick rolled oats (gluten-free, if needed)
  • 4 Large organic medjool dates (diced)
  • 1/4 cup organic raw coconut crystals (or granular sweetener of your choice)
  • 3 tablespoons organic ground flax seeds
  • 1/4 cup organic unpasteurized almond flour
  • 1/2 teaspoon baking powder (aluminum-free)
  • 1/2 teaspoon Himalayan pink salt
  • 1/2 teaspoon organic vanilla bean powder
  • 2 flax eggs (2 tablespoons ground flax seeds + 4 tablespoons water)
  • 1/3 cup organic walnuts (chopped)

For the frosting

  • 1/2 cup organic raw cacao powder
  • 4 tablespoons organic coconut oil (soft/semi-melted)
  • 2 tablespoons organic maple syrup (or raw honey, coconut nectar, etc)


Prepare the flax eggs
Step 1 Prepare the flax eggs by mixing 2 tablespoons ground flax seeds + 4 tablespoons purified water and whisk until well combined.

Let the mixture thicken while you prepare the rest of the ingredients.
OPTIONAL STEP: Process the oatmeal and dates
Step 2 Put the dates (pits removed) and oatmeal in a food processor and process with 20 - 25 long pulses just enough to dice up the dates and break the oats into smaller pieces.

Don't over process because the oats will turn into oat flour.

If the dates are not in small enough pieces, remove them from the food processor and dice them into smaller pieces.
Prepare the cacao mixture
Step 3 Add the cacao powder, melted coconut oil and vanilla extract in a small bowl and stir until well combined. Set aside.
Prepare the dry mixture
Step 4 Add the diced dates, oats, coconut crystals (or other granulated sweetener), 3 tbs ground flax seeds, almond flour, baking powder, pink himalayan salt, walnuts into a medium size bowl and stir together.

Combine all ingredients
Step 5 Mix the dry mixture, the cacao mixture and the flax eggs together and stir until well combined.

Put the mixture into an 8 x 8 glass baking dish and use your hands to pat it down flat because the mixture will be thick.

Bake at 350 degrees for approximately 20 - 25 minutes, or until cooked completely.
Prepare the chocolate frosting
Step 6 Add all the ingredients for the frosting in a small bowl and stir until well combined.

Let the brownie cool completely before adding the frosting.

Keep the brownies in the refrigerator until ready to serve.



This recipe will make approximately 16 brownies.

    May I suggest that you put the “yield x amount of servings” on your recipes. I have 7 grandchildren so I really need to know how many servings a recipe makes. Thanks

    • Karielyn says

      Hi Melody! I make these in an 8 x 8 glass dish and if you cut them into regular square sizes, you should get about 16 squares. You could also cut them into smaller squares to get more servings.

      Thanks so much and I hope your grandchildren like them. You’re a good grandmother for making them healthy treats 😉

  2. Lisa says

    I have just started my new clean eating way of eating and made these yesterday. They were fabulous, and the children loved them. Definitely will do them again. Can they freeze well? Cheers, Lisa

    • Karielyn says

      Hi there Lisa! Congratulations on making a change to healthier eating..yay! I’m so glad you enjoyed the brownies and that your children loved them as well.

      I’ve never had any leftover to freeze, but I don’t see why they wouldn’t do well. The icing will get hard and solid because of the coconut oil, but if you leave them out at room temperature for a little bit (maybe 5 – 10 minutes or so?) the icing will soften up. But don’t leave them out too long because then the icing might get too soft and melt, again because of the coconut oil.

      Thanks so much for trying out the recipe and for taking the time to let me know you enjoyed them 😉
