YOU GUYS. THESE BROWNIES. I seriously can’t help the all caps right there because these rich, fudgy gluten free brownies are THAT amazing.

I’ve spent years testing and perfecting a gluten free copycat for Ghirardelli boxed brownies and I’m not trying to brag but I nailed it and now you get to reap the reward!

They have the perfect amount of deep, rich chocolate flavor (I mean, who doesn’t love chocolate?!), the perfect balance of soft and chewy texture, and they are so moist and fudgy.

This gluten free brownie recipe has become my go-to recipe and a popular tried-and-true recipe for many of my long-time readers. It’s the base for many of my other brownie recipes like Peanut Butter Frosted Brownies, Coconut Frosted Brownies, and Chocolate Covered Strawberry Brownies.

You can use this recipe as a delicious canvas for different mix-ins and toppings or enjoy the recipe as is.

Pro Tips and Secrets for Baking Better than Box Gluten Free Brownies

There are a few secrets I’m sharing with you so you can achieve the same amazing baking results.

  1. Use cold water and cold eggs. I normally bake with room temperature ingredients but for this recipe, I bake with cold ingredients to prevent the brownies from rising quickly and sinking in the middle. I’ve tested this method over and over again and this is how you’ll get the fudgy, chewy, soft, evenly baked brownies you’re craving.
  2. Adding a little extra cornstarch helps produce a softer texture.
  3. A small amount of water adds just enough moisture to the brownies to keep them moist. I’ve tested this recipe by using more oil or butter but the extra fat makes the brownies too greasy. Water was the perfect compromise for keeping the brownies moist, light, and non-greasy.

Notes

  1. For dairy free brownies, use melted vegan butter in place of the regular butter.
  2. I prefer my brownies very soft and on the slightly under-baked side. Cook a little bit longer if you want the center to be a little more done.
  3. Chill the brownies for 30 minutes for cleaner cut slices.
To Double this recipe:
Use a metal 9x13 pan instead and just double the recipe.  Now it's double the deliciousness!  Now that you have some extra brownies, you can freeze them for later on. Read on below on how to best do that!

Suggestions for storing and freezing your GF Brownies:

Storing: After making these brownies, you can store them in an air tight container for 2-3 days at room temperature.
Freezing: For best results, freeze the brownies on a baking pan in your freezer on wax paper for 2-3 hours. Then, I recommend wrapping each brownie in plastic wrap and then storing in a gallon sized freezer bag. When you're ready to enjoy these little bites of deliciousness, take them out to defrost for a couple of hours ahead of time.  Easy-peasy!

  1. Christy says:

    Is there an alternative to the sugar? Like honey? Or maple syrup?

    We usually don’t have real sugar in our house.

  2. Mary G says:

    These brownies were great! Loved the fudginess! But I would like to know if the cocoa can be subbed with a baking chocolate bar? I usually have that handy and I would like to be able to use when needed. Do you think it would work with some modifications?

  3. Jackie says:

    These are five-star brownies, hands down.

  4. Jenelle H says:

    Made these last night, and they came out great! I used a cheap cocoa powder, which next time I will get a good dutch cocoa because I think that is the only thing that would have made these even better! They are super rich, which is perfect for when I’m craving something chocolaty! Another winner recipe – thanks Shay!

  5. Ruth Mclaughlin says:

    These are absolutely the best Brownies, EVER!

  6. Ruth Mclaughlin says:

    I haven’t made brownies from scratch in probably 50 years, because I like them sort of soft and gooey in the center, too. I may have tried a couple of times, but never was satisfied. So, I’m really happy to have this recipe, Shay. The brownies are in the oven now, but I can tell already by the texture and appearance that there will be no more mixes for me!

  7. Jenna M. says:

    Delicious!!!! Needed last minute brownie recipe for my brothers birthday and these turned out to be the best brownies we have ever had!!! We used Namaste Perfect Flour Blend for the flour, omitted the zanthan gum since the flour blend has it, doubled the salt, and only ended up using 1 egg because that’s what we had left in the fridge (oops!). It still worked perfectly and other than being a little messy to pick up (assuming that second egg would have helped that lol!), they were perfectly fudgy with just the right texture and richness and sweetness and chocolately goodness! Will absolutely make these again and again!

  8. Alana says:

    Do you have any idea how I could substitute ghee for butter in this recipe? Or, how would you suggest to make this dairy free?

  9. Jill says:

    Can I make these in a glass pan? I only have a 9×13 metal pan and an 8×8 Pyrex.

    • Shay says:

      Yes, you can make them in a glass pan. If you want to bake them in a 9×13 pan, just double the recipe and increase the baking time a bit 🙂

  10. Cindy Lamoureux says:

    Made these today with cup for cup flour and added the xanthan gum even though it is in the flour. I have found over the last 13 years that the texture and foundation of baked goods comes out better. I also doubled the recipe as I have company coming. These are fantastic! Best recipe for brownies I have found. Thank you, thank you!

  11. Amy Holland says:

    Amazing brownies! I made them with my granddaughter, so I cut a corner and used Pamela’s pancake and baking mix, but otherwise followed the recipe. My chocolate loving family could not stop eating them! These will be a mainstay recipe for us.

    Thank you for sharing!

    Amy

  12. holley says:

    Have you tried these fudgy brownies with coffee added? I’m a nut for mocha…

  13. Mara DeLucia says:

    Just made these this afternoon using apple flour. Honestly, hands down the BEST gluten free brownies… ever. That is saying something because we have tried many!

  14. Desiree says:

    These are so GOOD! It is the one gluten free recipe my hubby loves! He hates everything GF, so this says a lot! I on the other hand have no choice and must eat GF, so I’m happy to find a brownie recipe that tastes better than the gluten kind. Thanks for sharing!

  15. April says:

    Can the sugar be substituted with something else like coconut sugar?

    • Sharon says:

      Hi April, I haven’t tried this with coconut sugar. Let me know how it turns out if you do end up trying it. I have a feeling that the coconut sugar will make these a bit more cakey vs. fudgy.

  16. Patty says:

    5 stars
    These look awesome! How do you freeze your brownies? Thanks!

    • Sharon says:

      Thanks Patty! I cut them into pieces and then freeze them in a freezer bag. I pull out what I need and defrost them at room temperature as needed 🙂
      If I have more than one layer of brownies, I place a piece of wax paper in between the layers so they don’t stick.

  17. Karli says:

    I was going to ask the same question. I tried using flax egg instead, but that didn’t work so well. They are just so good though, but the egg is not so good for me. I was hoping someone had tried a substitute.

  18. Sarah says:

    Do you need the xantham gum and cornstarch when using Bob’s Red Mill 1 to 1?? Also do you think if I replace the water with espresso they will come out the same but with a coffee flavor?

  19. Darla says:

    Do you add the xanthan gum even if the gf flour mix has it also?

  20. Susann says:

    Can coconut oil be substituted for the avocado/canola oil? These look amazing!

  21. Natalia says:

    Sharon, I just made these because you had me mouth watering with those pictures and OH- MY- GOD!!!! I just ate half the batch on my own!!!! Top top top recipe! Super easy and super fast… Thank you for sharing it! <3

  22. Jennifer Baxter says:

    Hi, I tried these last night and loved them. I had been craving cake or something sweet since discovering my gluten allergy and these were just what I needed.

  23. Karli says:

    Ok you guys if you haven’t tried this recipe yet, you better get on it. Seriously just replaced my all time favorite brownie recipe with this one – it’s amazing! So chewy and chocolaty, just perfect! Also Sharon thank you for your help on my gluten free baking conundrum I was having with my sugar 🙂 Your help gave me the best baked goods again! Yay!!

  24. Larry says:

    Can I use more xanthan gum or arrorwroot as a substitute for the cornstarch?

    • Sharon says:

      Hi Larry,
      You could sub tapioca flour or potato starch for the cornstarch. If your flour blend has arrowroot in it (mine does) I wouldn’t use extra arrowroot as it might make the brownies too gummy.

  25. SocialTech360 says:

    How thick do these brownies turn out in the 9 inch pan?
