Your friends and family will have no idea these soft and delicious grain-free brownies are made with cassava flour. They’re gluten-free and paleo friendly!

This post is sponsored in partnership with Bob’s Red Mill. Thank you for supporting the brands I work with that help me bring you new recipes! As always, all opinions and thoughts expressed are my own. 

Cassava what? 

I want to call these “Casanova Brownies” because they’ll have you falling in love with every bite.

Casanova – cassava… get it?

Okay but SERIOUSLY. You won’t believe how delicious these brownies are. And they’re made with CASSAVA FLOUR – a new-to-me flour that I’m excited Bob’s Red Mill has added to their collection of products! You may know I am a huge Bob’s fan (who isn’t?) and I’m excited to continue our partnership this year using their high-quality products.

What is Cassava Flour?

Cassava flour is a gluten-free, grain-free and nut-free flour made from the whole root of the cassava plant. Bob’s Red Mill cassava flour has a mild flavor and fine texture that is perfect for gluten free cooking and baking, and it’s also non-GMO project verified.

Bob's Red Mill Cassava Flour

I wanted to test my hand at cassava flour and it’s been a while since I’ve shared some brownies with you so let’s do this!

Note: Some say it’s a 1:1 conversion with wheat based flours, but unless you’re an avid baker I would use caution when subbing. This recipe was tested several times specifically using Bob’s Red Mill cassava flour. 

The Best Cassava Flour Brownies

Ingredients You Need

  • dark chocolate chips – please use a higher quality brand if possible! We’re using a full cup of chips and using a cheap store-brand bag will affect the outcome of this recipe.
  • unsalted butter – unsalted butter is best here, but oil may work as well.
  • granulated sugar – something like coconut for a paleo friendly recipe would be best, but cane sugar also works.
  • eggs – eggs help hold everything together here. I haven’t tested this recipe without.
  • vanilla – enhances flavor
  • unsweetened cocoa powder – I love this one.
  • cassava flour – grain free, nut free and gluten free!
  • salt & baking soda

How to make Cassava Flour Brownies

These brownies come together like a traditional, fudgy brownie recipe.

Melt Chocolate / Whisk in Sugar + Eggs

First you melt down the chocolate with butter until smooth – you can do this via stovetop or microwave.

TIP: If using the microwave I recommend using half power (my microwave is pretty strong) and time intervals of 30 seconds, whisking until smooth.

Why melted chocolate? Because that’s where the fudge factor comes in. 

Next you’ll whisk the sugar into the slightly cooled chocolate–butter mixer. And add the eggs and vanilla.

Combine Dry Ingredients with Wet

Next the dry ingredients – cassava flour, cocoa powder, salt and baking soda – get added into the mixing bowl. The batter will be thick and fudgy-looking – almost a cross between frosting and batter.

Don’t Over-Bake

Then the brownies go into the oven! You’ll need about 17-20 minutes here, but everyone’s ovens are different. And it would be tragic to over-bake these so watch your baking time and brownies closely.

How to tell when brownies are done

While baking time can help give you an idea as to whether or not your brownies are done, the best indicators are your nose, eyes and the toothpick test.

  • Your house should begin to fill with the lovely scent of baking chocolate
  • Brownies edges should rise slightly
  • The top lighter in color
  • An inserted toothpick coming out with crumbs – not completely wet batter but also not completely clean.

NOTE: The brownies will set upon cooling (about 45 minutes) and you’ll get a lovely fudgy bite when they’re baked just right.

Recipe Notes

  • FLOUR: I have *not* tested these brownies with another flour. I also only used Bob’s Red Mill Cassava Flour so I can’t vouch for results from other cassava flours. I’ve heard different brands can produce different results.
  • BUTTER: You can sub a dairy-free butter but I did not test these with coconut oil.
  • SWEETENER: The granulated sweetener is needed her to keep the brownies from being bitter. It is not a good idea to sub with maple syrup or honey as the wet-to-dry ratio of ingredients will then be altered. I did not test with different sweeteners other than granulated and coconut sugar.
  • CHOCOLATE CHIPS: Since the chocolate chips also add sweetness to the recipe, it is best to use a high quality chocolate morsels that have some sweetness to them, i.e semi-sweet or 60% dark chocolate.
  • DO NOT OVER-BAKE: It is best to keep these brownies almost under-done, to avoid crumbling. They’ll set upon cooling. Trust me!

I opted for a little chocolate drizzle and sea salt dusting for a little extra “oomph,” if you will. But these cassava brownies are totally delicious without the extra presentation.

Happy baking!

Delicious, soft and fudgy grain-free cassava flour brownies. Whether you’re following a gluten-free diet, looking for a paleo dessert or just want a healthier baked good, you will love these!

  • Author: Ashley
  • Prep Time: 10 minutes
  • Cook Time: 20 minutes
  • Total Time: 30 minutes
  • Yield: 16 squares 1x
  • Category: dessert
  • Method: Oven
  • Cuisine: American
  • Diet: Gluten Free

Ingredients

Scale
  • 3 tablespoons unsweetened cocoa powder
  • 1/3 cup plus 1 tablespoon cassava flour* (weighed 60 grams)
  • 1/2 teaspoon salt
  • 1/4 teaspoon baking soda
  • 1 cup quality dark chocolate chips (6 ounces)
  • 1/2 cup unsalted butter
  • 3/4 cup granulated sugar (organic cane or coconut)
  • 2 large eggs
  • 2 teaspoons vanilla extract

Instructions

  1. Preheat oven to 350ºF and line 8×8 metal baking pan with parchment paper; set aside.
  2. Combine dry ingredients: In a medium bowl combine cassava flour, unsweetened cocoa powder, salt and baking soda; set aside.
  3. Combine wet ingredients: Using medium saucepan over low heat melt together chocolate chips with butter (or ghee), whisking until smooth. If using microwave, use large glass bowl and melt chocolate chips with butter on half power in 30 second intervals, whisking in between time until smooth. Allow mixture to cool slightly, then whisk in sugar until smooth, about 1 minute. Add vanilla and whisk in eggs for 2 minutes (or use hand mixer on medium speed).
  4. Transfer chocolate mixture to large bowl (if you used a saucepan) and add dry ingredients; use large silicone spatula or wooden spoon to mix until combined. Batter will be thick and fudgy, almost frosting-like consistency. Transfer to prepared baking pan, making sure batter is evenly spread into all four corners. Gently bang on the counter to settle the batter if necessary.
  5. Bake brownies for 17-20 minutes. Watch baking time carefully – Edges of brownies should rise slightly when done. Use inserted toothpick to check for wet batter. If toothpick comes out with very wet batter, brownies probably need another 2 minutes. If toothpick comes out with crumbs, brownies are done. I think it’s best to be more cautious with this recipe and bake them almost under-done. You don’t want the toothpick to come out clean – that means the brownies are over-done.
  6. Cool: Allow brownies to cool at room temperature in pan for 45 minutes to 1 hour. You can also cool brownies in fridge. Lift parchment paper and set brownies on cutting board; use large sharp knife to cut brownies into 16 squares. Tip: wipe knife clean with damp paper towel before each cut.  ENJOY!

Notes

Please follow recipe as written following notes in blog post for best results! Use an 8×8 metal baking pan, as different materials hold heat differently.

If you’d like to add the chocolate drizzle, melt together 3 tablespoons of chocolate with 1/2 teaspoon coconut oil. Drizzle over cut brownies on parchment paper and dust with flaked sea salt. Option to also omit last 1/3 cup of chips from batter if you don’t want chocolate chips baked into brownies.

*I have not tested this recipe with other cassava flours. I’ve heard sometimes they can produce different results depending on the recipe. I can only recommend Bob’s Red Mill here.

**I have not teste this recipe with coconut oil but it may work. A dairy-free butter like Earth Balance should work though.

    I tried it with Otto’s casava flour and sugar in the raw. They were good but came out moist dry (Still good though) vs fudgy. I wonder if it’s because of the flour as you mentioned. The sugar in the raw was a good substitute. Kids loves them so there’s that!

      Unfortunately they’d be quite bitter without the additional sugar! I don’t necessarily recommend it unless you don’t mind unsweetened brownies.

    This recipe makes a very rich and delicious brownie. I prefer a denser chewier brownie and this one is rather tender and delicate. Still a keeper. I used Vitacost brand flour and took the brownies out when slightly under done, as per instructions above. Thank you!

    This is the best thing I’ve eaten since going plant paradox. I’m in love with these. I did make changes. I used monk fruit and coconut oil. Baked in a muffin pan for 25 minutes. Oh and wal mart brand cassava. Fantastic!

    Followed this to a T. But it was so so so dry. I have never made dry brownies in my life. I ended up making a pudding and poking holes in it and pouring it over. Really I don’t know how people get this to work for them.

      So sorry these didn’t work out for you, Lauren! The type of cassava flour used could be a factor. Or oven temp/time.

    This recipe made delicious gluten free brownies! I was very surprised by the texture—very moist and light and super chocolatey. First time using casssava flour and I will continue to use it! Thanks so much! I recently had to turn gluten-free for a thyroid issue so giving baked goods was disappointing but these make up for it. My kids liked them too!

    My husband is abstaining from egg yolks, made with 2 egg whites. Gooey after 18 minutes. Baked an additional 15 minutes. Batter was a bit oily. Came out a bit dry but very good. Thank you for creating and sharing.

    I am an avid baker of both grain free and conventional flour recipes and these are hands down the best brownies I have ever made. The pan was gone in less than a day……so next time I make double 🙂

    I can testify to the fact that granulated Swerve works perfectly in these as a sweetener, 1 to 1! I also used Lily’s semi-sweet chocolate chips, which melt really nicely and are sweetened with stevia and erythritol. Both of these ingredients are 0 net carbs. For my body, I can handle the glycemic load of the cassava and cocoa powder, but I know adding sugar and sugary chocolate chips on top of that would be a bad idea. If it helps anyone, with the above ingredients, 1 brownie (1/16 pan) is only around 3.11 g net carbs, per my calculations!

    These brownies came out amazing. I’m so happy to have found this recipe, and swaps that work, as the cassava flour brownie recipes I’ve tried that were designed for low-glycemic sweeteners have come out horrible. Thank you SO much for this recipe, Ashley!
