    This is a GO-TO recipe for special events. Birthdays are happily celebrated by all with this amazing flavor! I am so happy I found it and pinned it and make it often! Planning on making it for our son’s wedding rehearsal dinner. I will be doubling it and hope it works beautifully in a pan, the cast iron is always amazing!

    • replied:

      Ahh I’m so glad to hear that, Sarah! Such a great one for celebrations 🙂 The cook time will definitely increase if you double it, just FYI!

    These were absolutely delicious!! Thank you, Monique! The walnut butter was surprisingly easy and tasted AMAZING!

    • replied:

      So happy you loved them! Isn’t that walnut butter the best?!

    Made these today with a few modifications & they turned out wonderfully! I used walnut butter & some mixed nut butter I had (with chia seeds already added in). I wanted to cut down on the sugar, so I also subbed Lakanto monk-fruit sweetened syrup for the maple syrup, subbed 1/2 of the coconut sugar with Swerve brown sugar, & used Lily’s stevia sweetened chocolate chips. I love the texture & the flavor of these!

    • replied:

      Glad those swaps worked out well!

  • says:

    These brownies are super delicious! My whole family enjoyed them. Don’t hesitate to try this recipe. You won’t be disappointed.

    Finally! After making grain free, lower carb treats, this recipe comes along!!! It’s perfection. So tasty. Tastes like a regular brownie but with magic. Thank you. This is my first recipe of yours and I can’t wait to try the rest!!!

    • replied:

      I’m glad you found this one! I have tons of delicious, grain free treats you might like – check out some of my other favorites here 🙂

  • says:

    Insanely the best brownies I have ever made! Can’t stop eating them.

    • replied:

      Amazing! Glad you loved them 🙂

  • says:

    Sounds delicious! Can i substitute the walnuts for almond butter?

    • replied:

      Yes, I think that would probably work well, although the almond butter should be very runny/drippy.

  • says:

    This looks great! Any suggestions for substitutes for the maple syrup and coconut sugar? I don’t do any kinds of “sweeteners” except monk fruit or stevia.

    • replied:

      I typically only bake with natural sugars (coconut, maple syrup, honey, etc.) so I’m not sure what the stevia equivalent would be in baking!

    I was just told to try a no grain and no dairy diet for one month. I was devastated. Then I saw your recipe. I tried it and have to say that this is delicious. I would eat the whole thing but had to be good so split it up and freeze portions for other times. Now I have a good dessert to look forward to as a treat! Thank you for sharing!

    • replied:

      I’m so glad you found this recipe, Linda! I have tons more grain + dairy free recipes here too that I think you’d love 🙂 Check out this list for some great ones!

    I have tried flax eggs before in several gluten free or paleo brownie recipes in hope, but I too have had the same results… Oily and almost tar like. Sad to say, but it might be how it goes

    • replied:

      Very strange! Flax eggs usually work well for me when I sub them. I would make sure that you let them “set” in the fridge before baking with them!

  • says:

    Is there a substitute for the chia seed? I can’t have chia. Thanks.

    • replied:

      Hi Gail – you can leave the chia seeds out! Enjoy.

  • says:

    Hi Monique! These look delicious! What if I have walnut flour? Could I substitute, and how much?

    • replied:

      Hi Ameena! I’ve actually never tried baking with walnut flour, so I’m not 100% sure how it might affect the texture. If you do replace the coconut flour with walnut flour, let me know how it goes!

  • says:

    Do I put the Pan in the oven ? at 350? and is it not going to ruin the pan?

    • replied:

      Yep! The skillet will be just fine in the oven 🙂

  • says:

    I just tried making these with flax eggs, and the recipe didn’t work for me. I cooked them for 12 additional minutes, and the center was still quite gooey. I like gooey brownies, but they tasted undercooked. Also, there was so much oil pooled in the bottom of the pan that it was literally dripping off the brownies when I scooped them out. Has anyone else tried these with flax eggs, and did they work for you? They tasted great, and I love the idea of making them from homemade walnut butter. I am curious if less water per flax egg (I used a ratio of 1 T. ground flax + 3 T. water per egg as recommended in the comments above) or an extra T. of coconut flour might make them cook better. Suggestions? I would love to try them again, but the ingredients were expensive, and I would hate for them to be undercooked/terribly oily again. Thanks!

    • replied:

      Hi Ivy! The consistency should be the same as regular brownie batter, so there shouldn’t be excess oil dripping. Maybe try using 1 flax egg rather than 2?

  • says:

    Hi!

    I only have cashews handy and dates instead of coconut sugar. Could I use these two substitutes?

    Thanks!
    Jesss

    • replied:

      Hi Jess! You can use cashews to make a cashew butter for these, but I would stick with a granulated sugar (like the coconut sugar) in order to maintain the consistency of these brownies.

  • says:

    Hi Monique, Do you have an egg substitute I could try for this recipe?

    • replied:

      Hi Mindy! Feel free to use a flax egg, which is 1 tablespoon of flaxseed meal + 3 tablespoons of water. Let it thicken up in the fridge for a bit and then it should work just like an egg!

  • says:

    Just made these and they are delicious! They are wonderfully moist and just sweet and chocolatey enough to satisfy my daily sweet tooth/chocolate craving without the guilt. BTW, I also did not know when to add the chia seeds, so I did it with the chocolate chips. It seemed to work.

    • replied:

      Such a great treat! And noted on the chia seeds here – recipes has been updated 🙂

  • says:

    I am in the mist of making this – just poured batter into a pan and realized I didn’t add the chia seeds because they’re not in the directions…when do those go in?

    • replied:

      Hi Lily! I hope you enjoyed these! Thanks for the heads-up – you can add the chia seeds when you stir in the cocoa powder, coconut flour, etc. I’ll be sure to add to the directions!

  • says:

    These look so good! I can’t wait to make them.

    • replied:

      I hope you do and love them!

  • says:

    I can’t eat a lot of brownies due to my health condition (LPR) 🙁 , but these truly look irresistible.

    • replied:

      Sorry to hear that! Sending over good vibes, Luna!

  • says:

    I have almost everything to make this and a dinner party coming up tomorrow, with a big crowd to feed. Plus, one of them is gluten-free and one is vegan so this’ll be perfect with a flax egg!

    • replied:

      Perfect! I hope everyone enjoys them!

  • says:

    Can I use a regular pan?

    Thanks!!

    • replied:

      Hi Marisa! You could use a 9×9 inch square baking pan for these 🙂

  • says:

    I currently have these in the oven but I realized that when I pulled my nuts from the pantry, I accidentally pulled pecans and made the brownies with pecans… I’m missing out on those omegas from the walnuts…. but I’ll let you know how it tastes with pecans.
    Also, on a side note… in the directions it doesn’t say when to add the chia seeds. Just an FYI.

    • replied:

      Another side note…. they were pecan pieces… I know what pecans and walnuts look like, but when they’re in pieces… I didn’t realize. HA!

      • replied:

        Whoops! Well I hope they turned out just as delicious!

  • says:

    I’m allergic to walnuts. Could I use pecans instead? I’m sure I could add homemade peanut butter. I’m allergic to cashews too.

    • replied:

      That should work just fine!

    I am LOVING these grain free desserts! I recently cut out gluten & all grains, and this recipe looks so delicious! Good work!

    • replied:

      These will be perfect for you! Hope you enjoy!

  • says:

    Could you use honey instead of maple syrup?

    • replied:

      Hi Lauren! I wouldn’t recommend it as the honey will overpower the flavor.

  • says:

    I don’t have coconut flour. Could I sub with almond flour or something else?

    • replied:

      Hi Sue! I haven’t tried another flour – the coconut flour is actually what binds these ingredients together, so I’m not sure another flour would yield the same results!

  • says:

    Have you ever substituted applesauce for the egg in this? That’s usually my go to sub and I’m curious as to if you’d tried.

    • replied:

      I haven’t, but I’ll let you know if I do!

  • says:

    Wow, I just have to try making this amazing looking brownies. They look super yummy for my tummy:)

    • replied:

      I hope you try them!

  • says:

    I mean omega 3’s in a brownie? I can’t think of a better reason to eat them!

    • replied:

      Ohh yes! So delicious!

  • says:

    if I didn’t want to make the walnut butter, how much pre made walnut butter do I put in ????

    • replied:

      Hi Joesy! You can add one heaping cup of walnut butter.

  • says:

    Oh my WORD!!! I love walnuts, especially in my brownies, and these look absolutely incredible. I just re-seasoned my cast iron this weekend so I’d say this skillet is in order!!

    • replied:

      The walnuts make them SO, so good! Fire up that cast iron 🙂

  • says:

    Okay wow, these look TOO GOOD. I love baking brownies when I’m having a bad day too. I think that’s how I discovered your “Bad Day Bars!” 😀

    • replied:

      Exactly! Brownies are the ultimate pick-me-up <3
