How to Replace the Eggs in a Box Brownie Mix

July 17, 2021 By Gretchen 37 Comments

“How to Replace the Eggs in a Box Brownie Mix”?

Sadly the most offered answer is: “Just use flax or applesauce or a banana!”
My reaction to those answers is always a cringing “No please don’t!”

While yes, technically those home pantry items will work, but my question to you is, “are they the best options?”

You already know my answer. It is “No, they are not!”
Trust me you will want to ditch those suggestions and follow my instructions for how to properly replace the eggs in a box brownie mix!

Fixing the Duncan Hines Box Brownies

Many people have berated me for using a store bought egg replacer as the fix it.

They just really wanted me to continue advocating for those other handy items like the can of soda as the ultimate fixer upper for a veganized box cakes and brownies.

But I just can’t do it!

I cannot advocate for something that while yes~ technically it works but the result is quite awful in my opinion!

Notes for Success & Substitutions:

In the video I show that I am using The Plant Based Egg~ egg replacer by Freely Vegan
This product is no longer available and I regret promoting it in my recipes so heavily
I now use Bob’s Red Mill in same quantity as listed as well as the tried and true “flax egg”.

You can use another egg replacer of your choice and I am confident you will get equally great results
As long as you follow the other ingredient adjustments!

UPDATE:: as of 2023 it seems that Duncan Hines (*and other brands) have changed their formulas!

    C and H sugar packages have a multi digit code on them. The first number indicates which processing factory it came from. C and H uses both bone char and non bone char factories. If the first number of the multi digit code is either 1, 4 or 6, this indicates the package of sugar was processed at a factory that DOES NOT USE BONE CHAR. Therefore it is vegan. Plus, unlike some sugars that claim “vegan” but which use GMO sugar beets, C and H uses sugar cane only and is non GMO. I got this info from calling customer service at C and H. Hope they’re not lying.

      What is C and H?? This seems like helpful info but can’t find where C and H are mentioned so not sure what they represent.

          I believe it refers to a brand of sugar. C and H is common here in the Midwest

      Came to say that the boxes brownies came out delicious! I made three modifications based on what I had on hand, plus the need for more chocolate. Instead of eggs replacer I used a flax egg, instead of oil I used melted plant butter, and I added about 1/4 cup of chocolate chips. Oh, and to half the pan I added walnuts on the top since I love them. That makes 4 modifications – ha! Thank you so much for all the work you did to test this out, Gretchen! Totally agree that applesauce, pumpkin, baking soda, etc. do not make for what I consider great brownies.

    Wow! Since being vegan for almost 5 years and always feeling dissatisfied with the result of various egg replacements in my Duncan Hines Brownie mix, this is finally the one that worked!!! We were all so happy with the taste and texture. Actually, I think it was even better than when we used to use eggs. Thank you, thank you, thank you. Can’t wait to try your cake replacement recipe for an upcoming birthday this weekend. 😊. So happy to have found your site.

      YAY thanks for the feedback! I have gotten some negative comments on the video (YouTube) for this recipe from people automatically saying “Just use flax, applesauce, SODA!” etc.. even though my video clearly says in the beginning all about those options! But, well… you know how people want to always be right LOL SO THANK YOU for verifying that I AM RIGHT! LOLOL

        Oh that’s crazy! It doesn’t matter what egg replacement I use, it just never turned out right until I found this recipe. People don’t know what they’re missing.

    I have tried recipe after recipe to veganize box brownies over the years. This recipe will now be my all time favorite! They stayed soft after leaving them out overnight. They were fluffy (I used the cakey version) the top had crispy texture. I added wal uts to my brownies. Even though I added powdered cocoa, I think added vegan chocolate chips would be an amazing addition. I cannot rave enough! Thank you! This recipe has ended a long hunt for the best recipe. On another note- my family, thatis not vegan would not stop raving about them!

    Thank you so much for sharing this recipe! I have tried over and over to veganize brownies and the results have always been horrid! I haven’t had a brownie in YEARS! This was so simple and they turned out perfectly fudgy, even my non vegan family loved them!

    I have made this recipe so many times, it is wonderful! I have substituted and added so many things to this recipe and it always turns out great! I prefer using apple sauce or pumpkin purée as the egg substitute I found out it makes the brownies super moist, and if you want some untraditional brownies add dried cherries it will be worth your while! Keep baking! 🙂

    Could this article get any longer, with a few more ads? Geez. And to find out it’s flaxseed, which doesn’t work.

    Love your directions for boxed cakes! My family gobbles them up. One question when you add the egg replacer is that after adding the water? Ex. 2 tsp plus the water added? Thanks so much!

      Hey thanks! Since I use the Plant Based Egg by Freely Vegan (that one doesn’t need to be reconstituted) So I add it straight to the dry ingredients, but I have also used Bobs Red Mill (which technically says to reconstitute it on the package) but I have also added that one straight to the dry ingredients! 😀

            You can omit the egg replacer as long as you make the other adjustments that I list in the recipe section

      The easiest thing I found online was to use the ground flax of 2 Tbsp and water of 3 Tbsp. Then, whatever amount of oil the box says, halve that and change that half to water. That’s in addition to the water that’s already an ingredient. That’s because eggs absorb oil and egg replacement doesn’t. I sometimes use plant based countey crock sticks melted instead of oil. That’s yummy!

    Flax, banana, applesauce, soda, baking powder, egg replacer, etc. are great substitutes for eggs in cakes but are absolute trash in brownies. Pumpkin or beans works ok. I’m going to use this recipe to use up a box of brownie mix I bought on clearance, but I feel like with all the extra ingredients, you might as well make brownies from scratch!

      I agree with you on the “may as well make from scratch” I did mention that in the video (maybe on the box cake hack though) but I will also say IT WORKS GREAT! LOL

    Hi Gretchen! Will be making these brownies this weekend too 🙂 I would have made them with the Freely Vegan Egg but have been unable to get it (trying for months) and am going to use Bob’s Red Mill for this. I would eventually like to try your flaxseed and Aquafaba combined “super egg” one day but don’t know what recipes that is best suited for LOL On my bag of Bob’s it says to use 1 Tablespoon to replace an egg but your directions say to only use 2 tsp of egg replacer – I want to make sure I’m doing it correctly – so do I follow your directions or Bob’s? Do I have to soak the Bob’s in water like it says or just add in like yours? Thank you so much for your help!

      Hey thank you for pointing out that I needed to update this recipe due to the specific egg replacer no longer being available,
      I use Bob’s Red Mill now, and I add it directly to the dry ingredients

    Made these today and topped with peppermint vegan “buttercream” and crushed candy canes. They were an hit! Absolutely perfect! I was worried that they would not turn out with that little of egg replacer but they totally did. Thank you!

    Hi, Gretchen. I have a bunch of Ghirardelli triple chocolate brownie mix from Costco. Would you recommend the same substitutions?

    Reply
    • Gretchen

      January 16, 2023 at 8:09 pm

      Hmm while I’ve not tried that brand, I would suggest to compare the ingredients on the box, meaning what does Ghirardelli say to add as far as water/oil/eggs etc to their mix in comparison to Duncan Hines? Duncan says to add 1 eeg/1/3 cup water & 1/2 cup of oil to a 18.2oz box. If Ghirardelli is same or at least very similar, I would say YES to the same subs! Also compare the box weights- I want to remember that Ghirardelli boxes are pretty big?

      **keep in mind you wont be adding in those ingredients they say to add, just use it as a comparison to see if you can follow my conversions here on my recipe

    These were really good! I’m not vegan but I don’t eat eggs so I followed the recipe and used 2 tsp of yogurt as the egg replacer. We like a little bit fudgier brownies so maybe I will put a little less baking powder next time. Thanks for the great recipe!
