Gluten-Free Vegan Walnut and Oat Brownies

Today I have for you another clean, healthy brownie recipe to add to your arsenal - Gluten-Free Vegan Walnut and Oat Brownies!

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:

Walnut Brownie Ingredients:  1/2 CUP BUTTER, 1 CUP GRANULATED SUGAR, 1 TSP VANILLA EXTRACT, 2 EGGS, 1/2 CUP ALL-PURPOSE (WHITE) FLOUR, 1/3 CUP UNSWEETENED COCOA, 1/4 TSP BAKING POWDER, 1/4 TSP SALT, 1/2 CUP CHOPPED WALNUTS

Chocolate Frosting Ingredients:   1 1/3 CUP CONFECTIONER'S SUGAR, 3 TBS MARGARINE, 2 TBS COCOA, 2 TBS MILK, 1/4 TSP VANILLA, 1/4 CUP CHOPPED WALNUTS

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

My healthier version is plant-based, vegan, gluten-free, dairy-free, egg-free, flourless, contains no refined sugar and is paleo-friendly.

Expert Tips + Ingredient Substitutions For Gluten-Free Vegan Walnut and Oat Brownies

Here are some expert tips to make this recipe perfectly:

Oats + Dates. 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 my Vitamix 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.

Coconut Oil.  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 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. In addition, if you don't like the taste or smell of coconut oil, use organic refined coconut oil which has zero coconut taste or flavor.

Brownie Texture. 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.

Cooling Time. 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.
