JUST Egg in Boxed Cake Mix – My Results

December 24th: I accidentally bought a cake mix that required 4 eggs because someone wanted funfetti for his birthday cake. Was Just Egg up for the job?!? YES!!!

Because six tablespoons worked so well as a substitute for three eggs, I sprang for eight tablespoons to replace four eggs. It’s every bit as moist and delicious, perhaps just a teeny teeny bit crumblier when sliced. I bet seven would have worked fine, too.

March 3rd: I originally made half a box of cake, but tonight I made a full box of cake mix substituting three large eggs for six tablespoons of Just Egg (added water and oil per the instructions). It worked out just beautifully. Super moist!!

Used olive oil for the oil and mixed the batter a minute or two longer than the recommended time for no particular reason.

…these were along the lines of what I’d been searching for last weekend when I could no longer wait to make a vanilla-flavored, vanilla-frosted confetti cake mix purchased a few weeks ago. The dairy-free mix called for oil, water, and three eggs. I hardly ever bake, and don’t recall the last time I tried to replace three eggs in a recipe (or with what) but that would be a problem for future-me!

When I do such investigative internet searching, like replacing up to three eggs for a specific baked item, I’m likely to go through multiple recipes and reviews to land on one I think is the right fit. I already had JUST Egg on hand, but all I’ve ever made was scrambled eggs and omelets with it, and wanted to give it a try. The internet surprised me by returning only one solid result to my yes/no question.

Thank you, WorldOfRandomStuff, for inspiring me to take a chance, by sharing your Just Egg: Replacement in Cake Baking Test video.

The twist to my experiment is that I only wanted to make half the box so I didn’t feel compelled to eat a whole cake for days until it was gone (even though Joel said he was OK with that). I simply halved the water and oil ingredients, and went with three tablespoons of JUST Egg. I was only going to go with two but got nervous it might not be enough.

What I Used:

  • Half (or 8 oz.) of the Betty Crocker boxed Party Rainbow Cake Mix powder (16 oz.) – it’s dairy-free!
  • 3 TBS JUST Egg
  • 1/2 cup water (half of what’s recommended)
  • 1/4 cup oil (half of what’s recommended)
  • Non-dairy vanilla frosting with sprinkles – we used all of it, so our entire dessert was half cake and half frosting… #notproud

I would think this egg substitute would suffice for most or any flavored boxed cake mix. The results were very moist, fluffy, and tasted delicious! Joel, who is omni, can’t wait until I make this again!

Do you ever take a forkful from the pan, but feel compelled to create a new line across so it’s more straight? So you take another bite? And another bite? Hoping for a straight line so anyone else in the household doesn’t think you’ve been eating from the pan? Not fooling anybody with my fork-cuts.

TLDR – I made half a box of cake mix that called for 3 eggs. I used 3 TBS of JUST Egg in half of the boxed mix recipe. Baked up perfectly and very moist. I don’t think anyone would know it was made without chicken eggs.

  1. Thank you! I’m on a family vacation where 3 of us (myself, the only vegan, included). They are planning to make a boxed cake to celebrate, which I would naturally be excluded from. Boo. Thankfully I packed a bottle of Just Egg and figured we could sub that in, but wanted confirmation that it would work. I’m so glad I found this!

    • Oops- left out part of my comment! 3 of us have birthdays this month. I’m not missing out on birthday cake, darn it!

      • Hi Nickie, make that four of us! 🙂 I will warn you, in my experience, omnis will have no problem helping you eat your Just Egg’d cake. Happy Birthday to us and thank you for your comment!

  2. Thank you very much for this recipe My grandson is 14 months and we just found out he is allergic to all egg products. It is very hard to find things for him to eat and I worry already that when he starts school and kids start to bring in cupcakes that he will try to sneak a bite. I can’t wait to try these recipes.

    • I’m so glad you found this easy substitute! I’m not fancy in the kitchen and it seemed like you can only successfully substitute a few eggs with alternatives; up to 6 TBSP seemed dicey. I was so impressed by the results, you’d never know the difference. I’ve made omelets with the liquid product, so you could easily make scrambled eggs for him. That’s how I started using the product – scrambled eggs and omelets. I wasn’t sure what else I’d do with it (one can only eat so many omelets.) I’ve used it in other recipes that called for 1-2 eggs, just never up to 6. Whole new world, so I hope you and your grandson’s parents feel inspired to give it a go! Good luck to him!
