Fluffy Vegan Lemon Cake Recipe that quite honestly doesn’t even need icing!
Lemon juice and lemon zest to the buttercream for a lemon cake that is going to have you begging for more!

This time I baked all the batter into a 9″ x 13″ cake pan for an easy sheet cake
However this recipe will also yield 2- 8″ cake layers or 3- 7″ cake layers as well

The texture of this cake reminds me of my cream cheese pound cake from my past life
Except there is no cream cheese in this recipe, just velvety lemon good that literally melts in your mouth!

This lemon cake recipe bakes into cupcakes too!
Just be aware that this cake will not dome so your cupcakes will be flat
Fill the cupcake liners slightly more than half full and bake at 350°F for 18 minutes

WATCH THE VIDEO TUTORIAL FOR HOW TO MAKE THIS CAKE

Notes for Success:
Because of the mix method I have created here for this super fluffy cake
It is essential to have the high speed power AND balloon whip attachment of an electric stand mixer. *see video for more
Many people ask about replacing the aquafaba in this recipe
If that is you I would recommend to use THIS EASY LEMON CAKE Recipe instead
When measuring cornstarch I cannot stress enough that a kitchen scale is the best way to go.
Cornstarch is a very difficult ingredient to measure consistently with a volume spoons measure
So while I list both measures below I cannot stress enough how the grams measure with a scale is going to give you the best results.
For best results I am using cake flour, if you don’t have that you can use all All Purpose flour
But the total quantity should be only 3 cups total weight (360g)
You can also use all vegan butter if you do not have or want to use coconut oil
This is a very delicate cake batter so be sure to bake it immediately no hotter than 350°F or it will get too brown and slightly dry on the edges
For larger cakes I will turn the oven temperature down to 325°F after the first 15 minutes of baking
PAN SIZES
This recipe will make 1 sheet cake baked into a 9″ x 13″ pan
Or it will also make 2-8″ layers OR 3-7″ layers.
Bake time will vary depending on pan size so be sure to check cakes at 20 minutes
Be aware that this cake recipe does not rise very much
So the depth that you fill your pans will be the end result as well

Fluffy Vegan Lemon Cake Recipe
Ingredients
for the icing
- 1 Recipe Buttercream
- 4 Tbs Lemon Juice
- 2 Tbs Zest
For the Cake Batter:
- 8 Tbs Vegan Butter 113g
- 8 Tbs Coconut Oil 113g
- 1¾ cups Granulated Sugar 350g
- ½ cup Plant milk 118ml
- ½ cup Lemon Juice 118ml
- 2 teaspoons Lemon Zest
- 1 teaspoon Lemon Extract 5ml
- 6 Tbs All Purpose Flour 48g
- 3 cups Cake Flour 360g
- 4 teaspoons Baking Powder
- ½ teaspoon Salt
- 2 Tbs Cornstarch 16g
- ¾ cup Aquafaba 177ml
Instructions
- Grease & parchment line your cake pans *see notes for success for pan sizes
- Preheat the oven to 350°F
- Prepare your favorite buttercream recipe as per the instructions & add the zest along with the juice at the last stage of mixing. Whip to smooth
- Prepare the cake batter~ Note: All of your ingredients should be at room temperature before mixing Cream the vegan butter with the coconut oil & sugar on high speed until light and fluffy approx 5 minutes
- Combine the plant milk with the lemon juice, extract & zest & then in a separate bowl combine the cornstarch with the aquafaba.
- Add the cornstarch/aquafaba mixture to the creamed butter mixture on low speed & once it is incorporated whip on high speed to emulsify. *the mixture will look severely curdled but will come together to a smooth silky batter by whipping on high speed. Be patient!
- Meanwhile sift together both flours, the baking powder & salt and then add about 1/3 of the dry ingredients to the mixer bowl while mixing on low-medium speed.
- Now add half of the milk/lemon mixture & mix just until incorporated
- Add another 1/3 of the dry ingredients mixing just until incorporated lightly then add the last of the liquid & then the last of the dry
- Whip on high for 10 seconds to develop the batter
- Pour the batter into your prepared pans & bake in the preheated 350° oven for 25-35 minutes or when a toothpick inserted into the center comes out clean. *for larger sized pans I like to turn the oven temperature down to 325℉ midway through baking to ensure it does not over brown on the top & edges
- Cool in the pan then flip out onto your serving platter then iice with buttercream, or build a layer cake as you desire!

Does it matter if I use aquafaba from a tin of chickpeas that contain salt?
Hey Gretchen! Can I use ALL vegan butter in this recipe?
yes!
Hi
The fluffy vegan lemon cake looks lovely. Could I make it into a lemon drizzle loaf cake?
I have a recipe for lemon drizzle using eggs, but I cannot find a good vegan one. I have tried several but they are not quite the same.
I hope that you can help me.
Thanks
Julie
Hey there! I’m not so sure I’m understanding what you mean by lemon drizzle cake. Since I think a lemon drizzle would simply be confectioners sugar with lemon juice to the consistency of a pour able glaze?
In which case- no eggs would ever be in that. So that leads me to believe I am thinking something completely different. IF by chance I am correct though- YES to Loaf pan and yes to confectioners sugar/lemon juice glaze! LOL
Can you please add cake size variations? I often have to make larger cakes and have to figure the adjustments for larger cakes.
Can I use flax meal instead of aquafaba. And what would be the amount.
Thank you Gretchen
While I have not tried this substitution, if I were to give it a go, I would probably use
3 Tbs of flax meal with 12Tbs water~ add the cornstarch to it same as shown in the video tutorial
https://youtu.be/9oCtPGpYVe0
I’m going to be trying this today Gretchen with flax meal. Just wanted to check do I need to just mix the flax meal with water and add cornstarch to it or should I cook it or rest it for a bit.
Hey Gretchen!
What would you suggest for cooking time for 8 inch rounds?
I would check at 18 minutes (toothpick test) see how it is going
Hi Gretchen, thanks for all of your wonderful recipes. Do you think I can substitute the flax aquafaba (from your buttercream recipe) here instead of the chickpea?
Thanks! Amanda
Yes! I believe it will work great!
Hello Gretchen! I made this recipe, it’s beyond delicious. I loved that fluffiness, ne er tasted such a good cake before. But, I would like to make it into just a white cake, I will be using a raspberry buttercream, your recipe of course. So should I substitute plant milk for the lemon juice? Thank you so much!
She has a white cake recipe here on her website! It’s delicious I’ve tried it!????
Omg, Gretchen
I have used tons of your recipes and getting into the veganess. I made the lemon cake recipe because I have to do a birthday party and wanted to vegan it out!! The batter of this cake is AMAZING!! The fluffiness, the taste is delicious. I know if the batter is good the cake will be the bomb. Thank you for all you share. ???????????????? And Happy Mothers Day!!
Is it possible to cut down the sugar and butter in this cake? Thanks
The ratio of ingredients are balanced in a way to make this cake perfectly fluffy, moist & have the rise necessary for that texture. Once you start to omit or change the ingredients you will see a dry crumbly cake that resembles cornbread instead of cake
Thank you for another fabulous recipe! I made this for a party with almost all non-vegans, and it was a huge hit. I used your recipe for cake flour by replacing some flour with cornstarch, I used all butter instead of butter and coconut oil, and I baked it as a 3-layer 6″ cake. I don’t have your decorating prowess, but it was still gorgeous. I made as smooth a surface as I could, then piped a few simple rosettes and did a little decoration around the bottom rim.
People said it was the best lemon cake they’d ever had, and that they were in love with the cake. (!!!)
You are the best. Thank you for this recipe, and all your other recipes.
OMG I just noticed I was supposed to add 6 tbsp of regular all-purpose flour as well as the cake flour and the 2 tbsp of cornstarch… I inadvertently omitted the all-purpose flour and it still turned out fabulously! It was so fluffy and soft and delicious.
Just made this cake ???? , got a bit confused with the instructions and added the Aquafaba and cornstarch together with the other liquids. My batter would not combine (think it had to do with mix up and the fact I had a hand mixer). I ended up with a three layer 9 inch round cake ???? wowsers what a. Big cake.
I also cut the icing sugar in half. Despite the mishaps it turned out fantastic. My daughter ❤️ it and so did everyone else
Thank you
WOW! I’m surprised that it turned out despite the reduced sugar (typically reducing my that much will result in a dry- cornbread like texture vs. a fluffy light crumb)
Were you able to watch the video tutorial for how to mix this recipe? It really does help to see it before you start
**It’s linked above the written recipe
Hallo gretchen,
Can I use gluten free flour instead the cake flour?
Greats nienke
Hi There, I have not tried GF flour with this recipe. I’m sorry I have no proper answer for you. If you try please let me know so I can note that here on the recipe
Gretchen,
Would this cake and method be safe to add blueberries to the batter or would it make it unstable?
I love all of your recipes!
Thank you!
Hi Thanks! This cake would be fine to add blueberries or any “add-ins” that are not liquids!
Hi Gretchen,
Can I use sunflower oil instead of coconut oil? I like the combination of butter and oil but I’d rather not use coconut oil.
Yes! I used coconut oil because it can be semi solid at times which helps in creaming versus just “sloshing” with straight up liquid oil, but in the summer when my coconut oil refused to be the least bit solid, I have done it with great results, thus making any liquid oiil you prefer a fine sub!
Hi Gretchen,
the ingredients for the batter do not list the lemon zest (which is only listed for the buttercream. How much lemon zest goes into the batter itself? 🙂
Thanks, Lee
Hey thank you for pointing that out! it would be the zest of 1 whole lemon about 2 teaspoons
I made this today and the crumb is sooo light and fluffy! Literally almost melt-in-your-mouth! While it did take a long time, it was SUPER worth it! I did make a personal “mistake”, and wanted to share in case anyone was wondering: had an unexpected meeting and the toothpick didn’t come out completely clean, so I turned off the oven and left it in there before I left the house. This caused the exterior became crispy (which is actually kind of nice, like a brownie haha!) but the interior was still very fluffy. I can see this cake pairing beautifully with a strawberry or raspberry jam for a layer cake 🙂 Will make again in the future. Thank you for the recipe!
Excellent! Thanks Anna for the review!
Thank you! Can this recipe work with a loaf pan too?
Yes!
Thanks, do I need to adjust the baking time?
hi Gretchen, thank you for a great recipe, could I use it for a lemon upside down cake? line a tin with slices of lemon, and pour this cake batter over top? thanks !
yes you can!
