Oat Flour Brownies (Gluten Free)

Oat Flour Brownies (Gluten Free!)

The universe must have really been listening to me on Wednesday, because it delivered some serious fall weather AND I LOVE IT. Big thunder storms, cooler temperatures — enough so that I actually got out my favorite sweater and spent the evening in it. Hallelujah! Keep it coming!

Oat Flour Brownies (Gluten Free!)

Also: I totally cracked open the pumpkin a day earlier than planned. I just couldn’t wait!! I’ll share what I did with it soon!

Oat Flour Brownies (Gluten Free!)

These oat brownies are something that have been on my list for a long time. It just sounded like a great idea to me: ground up oatmeal (the secret to these delicious cookies), mixed with chocolate and baked to perfection. I was psyched to try!

Oat Flour Brownies (Gluten Free!)

I’m happy to report, it worked wonderfully! Now I can make gluten-free brownies without worrying they’ll be weird, or having to use a strange ingredient. Maybe someone out there would consider oatmeal to be a strange ingredient, but I certainly don’t.

Oat Flour Brownies (Gluten Free!)

I based this recipe off of my favorite fudge brownie recipe, beefed up a little bit and translated to oatmeal-land. The oatmeal does give a distinct texture — a bit more substantial feeling (dare I say, healthy?). I’m a fan — even if I’m not gluten-free, although I suppose my posts this week have been leaning that way.

Recipe: by Mary
Ingredients
  • 1½ - 2 cups gluten-free oatmeal
  • ¾ tsp baking soda
  • ½ tsp espresso powder
  • ¾ cup unsalted butter
  • 1½ cups sugar
  • 1 cup cocoa powder
  • 1 tsp salt
  • 1 Tbsp vanilla extract
  • 3 large eggs
  • 1¼ cup chocolate chips
Instructions
  1. Preheat the oven to 350 F, and lightly grease an 8×8″ pan.
  2. In a food processor or blender, grind the oatmeal to a fine powder. Measure out 1⅓ cups oat flour, and combine with the baking soda and espresso powder. Set aside.
  3. In a saucepan over medium-low heat, melt the butter.
  4. Once melted, add the sugar and cook for another minute.
  5. Remove from heat and add the cocoa and salt. Stir to combine.
  6. Add the vanilla, and then the eggs one at a time. Whisk fully so that the mixture is smooth and glossy.
  7. Add dry ingredients to the wet ingredients, mixing until just combined.
  8. Stir in the chocolate chips (if you want them fully intact, let the mixture cool 10 minutes before doing this step).
  9. Spread the mixture into the prepared pan and cook for 30-35 minutes – the top should have a thin crust, but the center will still be quite moist.
  10. Let cool 20 minutes before cutting and serving.

    I love the idea of oat brownies, I have got to try this!

    Sounds delish! What if I don’t have espresso powder. Can it be omitted?

    • Mary says

      Absolutely!

    Saw these on Pinterest so I had to check them out. They look fantastic! 🙂 I can’t wait to try them myself. One word of caution to folks who are truly gluten free (eating gluten free for health reasons), the oatmeal/oat flour has to be certified gluten free. Mainstream oat products (e.g., Quaker, McCann’s, Country Choice) contain gluten. You might want to add “(gluten free)” after that ingredient since you’ve labeled the recipe gluten free.

    Thanks so much for the recipe!

    I’d love to make these GF brownies but I am confused about the amount of oat flour. Is it supposed to be 1-1/2 cups according to the list of ingredients, or 1-1/3 cups according to the directions? Please, let me know as soon as possible. Thank you!

    • Mary says

      9 December, 2013 at 3:00 pm

      Hi JB – sorry for the confusion! Use 1 1/3 cups oat flour. The 1 1/2 is in reference to the oats, which condense a bit after grinding into oat flour. Have fun!

        Mary this was awesome. I recently was found to fructose intolerant and have been experimenting with non wheat alternatives. Oat flour… Fantastic recipe, simple yet delightfully moorish. I added half a cup of smooth peanut butter and a handful of peanuts. This is going to be a regular. Many blessings.

        • Mary says

          20 July, 2016 at 5:18 pm

          Thanks, Liz! I’m so glad you liked it — and I love your addition of peanut butter!! YUM! xo

    My elder daughter is celiac. Tried it. Came out fantastic. While house is enjoying them. Don’t feel as if eating any GF stuff.
    Thanks a lot for sharing
    Looking for GF sponge cake recipe as well for tiramisu and chocolate mousse cake for my daughter which doesn’t have after taste like most of GF cakes and texture is also more granular like regular cakes so whole family including my daughter can enjoy them. Pls share it if possible

    Once again thx:)

    • Mary says

      12 December, 2013 at 2:48 pm

      MK – glad you liked them! I know cooking for celiacs can be a challenge. I don’t have a GF sponge cake recipe yet, but I’ll certainly let you know if/when I do!

  6. Jennifer says

    4 February, 2014 at 11:55 am

    If you replace 1/2 cup of the sugar with 1/2 of brown sugar the brownies are even better!

  7. Daniela says

    4 February, 2014 at 1:44 pm

    Just made these brownies and they are delicious! Although maybe I’ll use a bigger pan the next time, as I prefer them a bit flatter

  8. Aishah says

    5 February, 2014 at 7:28 pm

    it was soooo good! i felt good eating it cos there was no flour at all!
    mine wasnt really gluten free cos i just blended up my oatmeal.
    it wasnt as fudgy looking as yours, maybe my oatmeal flour wasnt as finely blended. but it was really good. it tastes so much better the next day, so moist and rich! thanks for the brilliant recipe!

  9. Meghan Larmore says

    27 February, 2014 at 10:17 pm

    How do I make these with just egg whites?

    • Mary says

      27 February, 2014 at 10:31 pm

      Hmm. I think leaving out the yolks (and therefore the fat) would drastically alter the texture of the brownies. If you DO go that direction, I would make sure to really whip the whites with the sugar to be quite fluffy/firm, then fold it into the chocolate. Let me know how it goes if you experiment!

    these brownies are simply awesome thanks for sharing your recipe my kid’s absolutely love these

    • Mary says

      4 March, 2014 at 9:25 pm

      Glad to hear it!

  11. Abby says

    7 March, 2014 at 11:32 pm

    Excellent! A brownie recipe, finally, that uses only oat flour (because some add some other flour, like whole wheat, AP, spelt, etc…which I don’t have on hand, except for AP when I’m into some serious refined ingredients baking). Thank you for this! All of these ingredients I have in my cupboard.

  12. Angela says

    1 April, 2014 at 9:27 am

    DO you have the nutritional info for these?

    • Mary says

      1 April, 2014 at 9:33 am

      I don’t, sorry!

    • Elsie Gasper says

      29 January, 2015 at 8:19 am

      Hi; for what it’s worth…I once calculated the nutritional value per piece of a “doctored” 9×13 carrot cake by using the nutritional values from the respective packaging of each ingredient in my cake. Maybe not a bull’s eye but close. Hope this helps.

  13. Chris says

    1 April, 2014 at 8:27 pm

    Could u do anything to cut down the amount of butter in recipe ? Maybe cut something else with butter ?

    • Mary says

      1 April, 2014 at 9:28 pm

      I haven’t done it any other way – but let me know if you try it with anything else!

      • tasha says

        16 July, 2014 at 7:29 pm

        I made mine with coconut oil instead and instead of cocoa powder I substitued organic chocolate hemp protein. Came out lovely, thanks!

    • Melissa says

      2 May, 2014 at 2:09 pm

      applesauce is a good alternative to use to cut down on butter

    • Kelly Galloway says

      27 February, 2016 at 8:51 pm

      I have substituted a significant portion (over half) of the butter in choc muffin or cupcake recipes with ripe avocado. Works wonderfully!

      • Mary says

        5 March, 2016 at 12:01 pm

        Awesome — thanks for the tip, Kelly! xo

    • Normajean Slagel says

      19 February, 2017 at 11:25 am

      You sure could try coconut oil or better yet coconut butter!

  14. Heather says

    8 April, 2014 at 6:32 am

    Can you use a sugar sub like stevia? If so how much?

    • Mary says

      8 April, 2014 at 9:28 am

      I’ve never used stevia, so I can’t answer you with certainty! I’m sure a google search would tell you the ratio for subbing! Good luck!

      • Claudette Floyd says

        11 August, 2014 at 1:38 pm

        I would try this recipe and I would used stevia too . And also coconut oil . Thanks for the recipe, and the post.

  15. aishah says

    17 April, 2014 at 9:31 pm

    yay to no flour! i made this twice and it turned out alright. just that it wasnt an fudgy as yours. mine was more like a rich cake. i wonder why.

  16. Lisa says

    27 April, 2014 at 9:54 am

    You can replace the butter completely with coconut oil. Coconut oil acts like butter but is way better for you.

  17. Gill Kim says

    6 May, 2014 at 4:38 pm

    Amazing! How do I make espresso powder? Is it as simple as it sounds. i.e. From grinding coffee beans?

    • Mary says

      7 May, 2014 at 6:28 am

      I don’t think it’s quite the same – I get the instant powder from the coffee aisle at the grocery!

  18. Sean says

    23 May, 2014 at 12:15 am

    This was a little too fragile/crumbly for me. Perhaps I’ll try a chia seed binding agent next time.

    • Mary says

      23 May, 2014 at 4:59 am

      Perhaps some flax + boiling water would work, too! Good luck!

  19. Liz h says

    7 June, 2014 at 12:07 pm

    I’ve made these several times and they never disappoint. This last time I swirled in a little peanut butter- yum! Thanks for a recipe my whole family can enjoy together!

    • Mary says

      7 June, 2014 at 5:54 pm

      Woohoo! So glad to hear you like them! Pb sounds like a great addition 🙂

  20. Manuel says

    22 February, 2015 at 8:50 pm

    I only eat egg whites: so how much egg whites would I have to use instead of the whole egg?

    • Mary says

      22 February, 2015 at 11:53 pm

      Hi Manuel! Generally, 2 egg whites = 1 whole egg. Subbing like that WILL reduce the fat content drastically, which will really change the texture of these brownies. To compensate, I’d recommend adding about 1 tsp of some sort of oil for each egg!

  21. Evie says

    26 May, 2015 at 11:43 pm

    i am intolerant to cow’ s milk’ would goat butter work instead or would it leave a strong goat taste? Or is oil an ok substitute? Thanks. E

    • Mary says

      27 May, 2015 at 11:44 am

      Hi Evie! I have absolutely zero experience with any of that, so I can’t really advise! Let me know what you end up trying, and how it works. Good luck!!

    • Sara says

      28 August, 2015 at 11:54 am

      Maybe it does make a difference, but I always use oil and mine came out perfect.. I did add 1/4 of almond milk because it was too dry for my taste.. 🙂

      • Mary says

        28 August, 2015 at 2:19 pm

        Thanks for the tip, Sara!

        • Kerrie says

          12 November, 2016 at 12:55 pm

          Mine too have come out dry and crumbly so do you suggest just a bit more liquid? Also I can find baking soda so I’m using 4 x the quantity of baking powder. Otherwise there so good just trying to get them a good consistency any other suggestions ?

          • Mary says

            13 November, 2016 at 11:54 am

            Hi Kerrie! I think the quadrupling of baking powder is probably the culprit here! Since these aren’t super leavened anyways, I wouldn’t worry about it too much — just use the normal amount (soda would be ideal, but the same amount of baking powder will be fine for this purpose!). Good luck!

  22. Michelle says

    18 June, 2015 at 2:07 pm

    These are so good! Best gluten free brownie I’ve ever had. Will definitely be my go to recipe

    • Mary says

      18 June, 2015 at 3:46 pm

      Thanks, Michelle! I’m glad you like them!

    24 July, 2015 at 7:40 pm

    Hey Mary – thanks for sharing! Unfortunately mine did not turn out like yours, but I did make a few changes. Instead of all of that sugar, I replaced it with coconut palm sugar and only 3/4 cup. I used cacao powder instead of cocoa. When mixing it, it seemed very dry, so I added some mixed frozen berries. I only baked it for 32 mins and it still came out really dry. Next time I would keep the full amount of sugar too and maybe use coconut oil instead of butter in the hope that it gives it that extra moisture?

    • Mary says

      25 July, 2015 at 9:56 am

      I think the change in sugar is a huge factor here — palm sugar acts pretty differently than white sugar, and reducing by 25% is significant! I’m not a scientist, so am not sure exactly how to instruct you… But keep trying! Good luck!

    13 August, 2015 at 12:44 pm

    I have been looking to parrot a ‘breakfast brownie’ I had earlier this summer. I’m hoping for good results with this recipe (the batter tasted great :- ). Subbed dried cherries (found them at Aldi’s) for half of the chocolate chips (ghiradelli 60% cacao), and ground some instant coffee to a powder for the espresso. Thanks, Mary!

    • Mary says

      13 August, 2015 at 4:36 pm

      What a great idea! Sounds delicious! Thanks, Marcia! xo

  25. Marita says

    4 September, 2015 at 7:56 pm

    I just put them on the oven, replaced the butter with canola oil, no coffee, and chop some pecans…amazing!!

    • Mary says

      7 September, 2015 at 7:11 pm

      Yay! I hope you loved them, Marita! Thanks for sharing! xo

    I replaced the eggs with 3 tablespoons of corn starch disolved in 9 tablespoons of water. These are awesome, I missed brownies.

    • Mary says

      23 January, 2016 at 11:58 am

      Yay! Thanks for the tip, Nikki! Welcome back to brownieland! Xo

    I tried them today and they are sooo yummy. I used dark chocolate instead of chocolate chips and the result was incredible. Thanks for the recipe!

    • Mary says

      6 February, 2016 at 2:48 pm

      Thanks for the feedback, Joey! I’m glad you liked them! xo

    21 April, 2016 at 2:45 pm

    These were the first brownies I ever made! They ended up lovely, I did not put so much sugar as I simply run out, and mixed white sugar with brown, but i liked them being not too sweet! Also used a bit of olive oil with butter and white chocolate chips together with dark chocolate ones. People didn’t realise they were gluten free!yumyy! Thank you for the recipe!

    • Mary says

      22 April, 2016 at 2:49 pm

      Thanks for your comment, Irina! I’m so glad you liked them! xoxo

    24 May, 2016 at 2:18 pm

    HI, I love these brownies! They are definelty my favorite recipe! I think you need to edit the recipe though because you called for vanilla and then the instructions never told my to put it in. I didn’t it with the rest of the wet anyway. 🙂

    • Mary says

      24 May, 2016 at 2:30 pm

      Hi Rachel! I’m glad you enjoyed these! The instruction to add the vanilla was at the beginning of #6! xo

  30. Christine Peterson says

    23 August, 2016 at 4:23 pm

    I used applesauce instead of eggs. I also used a cup of maple syrup instead of sugar and used 1/12 cups of oat flour and 1/2 cup of hemp. I used a grass fed butter and cocao nabs. its so delicious. My girls cant tell the difference. Delicious brownies that are somewhat healthy. Thanks

    • Mary says

      23 August, 2016 at 8:45 pm

      Thanks for the notes, Christine! I’m glad it’s a hit! xo

      • Jemima says

        10 January, 2017 at 2:50 pm

        I substituted butter with some water for extra moisture, cut the sugar by 1/2 cup, and cut the baking time by 10 minutes. Much better than the first round that turned out extra dry and crumbly!

        • Mary says

          12 January, 2017 at 2:37 pm

          Hi Jemima! I’m glad this round was better for you — thanks for the feedback! xo
