Recipe for a super fluffy vegan Rhubarb Crumble Cake – all dairy-free and egg-free. One-bowl vanilla batter + soft rhubarb + golden crumble on top = YUM!
May I present the fluffiest vegan Rhubarb Crumble Cake ever! This cake has everything you want: a super simple one-bowl vanilla base, soft rhubarb pieces in the middle and perfectly golden homemade streusel on top. The sweet vanilla base and streusel will balance out the rhubarb’s tartness. This is the ultimate spring goodness cake.
Cut the rhubarb in small pieces and sprinkle them with sugar. Let them sit for about 20 minutes. In this time, the rhubarb will get softer and lose some of its water. Drain the rhubarb before pouring it onto the cake batter.
Here’s everything we need: Rhubarb on the left, the one-bowl vanilla batter on top and homemade streusel in the middle. These simple streusel will make the perfect topping for our crumble cake and they are so easy to make!
The baking dish I used is 10×8 inches. The cake is big enough for 6 portions.
- 1 1/3 cup all-purpose flour
- 1/2 cup white sugar
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1 tablespoon coconut oil , liquid
- 1/2 teaspoon coconut vinegar
- 1/4 teaspoon vanilla extract
- 3/4 cup lukewarm water
- 1/2 stick cold vegan butter (EarthBalance, Alsan,...)
- 2/3 cup all-purpose flour
- 1/4 cup white sugar
- 3 stalks rhubarb
- 1 teaspoon white sugar
- For the RHUBARB: Wash, peel and cut the rhubarb stalks in pieces. Put them in a bowl, and sprinkle them with 1 teaspoon of white sugar or your preferred granulated sweetener. Let them sit for about 20 minutes.
- For the simple one-bowl VANILLA BATTER: Preheat the oven to 360°F/180°C. Place all the dry ingredients for the cake base in a mixing bowl and combine, add the wet ingredients and whisk until it's a smooth batter.
- For the STREUSEL: Put the cold butter, all-purpose flour and sugar in a bowl, mix and knead with your hands until crumbly.
- ASSEMBLE and BAKE: Oil the baking pan lightly and pour in the cake batter. Drain the rhubarb and spread the pieces evenly onto the cake better. Sprinkle the crumble on top. Bake it in the oven for about about 25 minutes. When the crumble is nice and golden, your cake is ready.
My baking pan for this cake was 10x8" / 26x20cm.

This is the most stunning rhubarb crumble I’ve seen! It’s so elegant, clean, and WHITE! Haha!
It looks like a sweet, buttery, lovely cloud just ready to be broken into with a fork!
Delicious my friend! Bravo!
Aww, thank you Rebecca! I love your description, it’s so accurate! It’s definitely the best, fluffiest rhubarb cake I’ve ever had, and the streusel on top were the perfect addition :)
This rhubarb crumble cake sounds sooo good Bianca! I was just looking at some rhubarb when I went grocery shopping yesterday but didn’t have anything in mind to make with it, so I left it there. I’m really wishing I grabbed some now so I could be making this right now! <3
Thank you, Kyra! Hahaa, I always buy neat seasonal ingredients, even if I have no idea what I want to make with it. I can’t be bothered with thinking about recipe ideas when grocery shopping, I need the pressure of having it at home and actually making something with it. I love how the rhubarb crumble cake turned out, so buttery and soft.
This fluffy dream of a dessert has been popping into my head constantly ever since I saw it in your newsletter last night :o I’m not even sure what makes it so dang light, must be the vinegar baking soda combo, but wow does it ever look magical. Almost giving me angel food cake flashbacks here with the light white cake and browned top! And did I mention I love streusel? Well I do. Deeply. This is beautiful <3
Thank you, Natalie! Yes, the vinegar baking soda combo is my go-to-leaving agent in baked goods :) Especially the coconut vinegar is so mild and soft and undetectable. It’s my favorite vinegar. I love streusel too, I’ll be adding them to more sweets & treats in the future. This was the first time I made streusel myself, I can’t believe I waited that long, they are so easy. :O
Every time I’ve seen this pop up on my social media feeds, it’s made my mouth water instantly! The texture looks so spot on. I love rhubarb season <3
Thank you Aimee! This rhubarb crumble cake is the best I’ve ever made with rhubarb. It’s so heavenly soft and perfectly balanced with the rhubarb’s tartness. It made me fall in love with rhubarb and spring in general :D
This looks so good!
Thank you Becky! I’m glad you like it :)
Hallo before I try this I have to ask what is coconut vinegar? I don’t know if I will find that here in switzerland …..can it be replaced with white vinegar?
Hi Liz, you can use white vinegar as a substitute :) I just like to use coconut vinegar because it’s a super mild, but you shouldn’t be able to notice the white vinegar in the cake. I got my coconut vinegar in an Asian store, in case you want to look for it :)
Thank you….I will look it il up in Asian shop then….have a wonderful week
That cake was just amazing. :) I had the chance to try it and I’ve been to Veg-Heaven.
I’m totally going to try some recipes at home. New ingredients are always a challenge but a fun one.
It was so nice to meet you. Thank you!

It’s so nice to hear from you, Kat! Thank you so much for leaving a comment!
I’m so glad everyone loved the cake (at least no one told me otherwise :D ).
It was such a fun day, I had a great time talking about a topic I’m really passionate about.
I hope you’ll give your vegan week a try soon :) Let me know if you need any info on substituting anything. I’m always happy to help.
All the best, Bianca
just stumbled upon your recipe and I will definitely give it a try and let you know if mine looks as delicious as yours!! :D
I hope you like it! :)
Thank you for sharing this recipe, everything is great apart from one thing. I’ve never used xylitol before, and didn’t know anything about it, until I’d used it for this recipe. It causes a laxative effect in many people! Which I didn’t know till I’d eaten it! I thought it might be worth giving people a warning maybe? I have digestive issues and this made me ill for a day. I’ve since made it again just using sugar and it was great.
Hi Emma, thank you for letting me know! You’re right, some people seem to have digestive issues with xylitol – especially when introducing the new sugar into their diet. I guess I was lucky enough to start with small amounts. However, I’ve changed it to white sugar in the recipe.
Hi Bianca, thank you so much for posting this wonderful recipe. Just checking, there is no vanilla added to the vanilla batter, is that right?
haha, I can’t believe I’ve never noticed that! I’ve just updated the recipe and added 1/4 teaspoon of vanilla extract to the batter. Thank you for being so attentive <3 I hope you like the cake if you give it a try :)
Thank you Bianca, this recipe sounds amazing and I look forward to trying it soon!
Bianca,
Thank you for the delicious cake recipe. My family and I really enjoyed it! I only made one substitution (which is really good for me:)), I didn’t have coconut vinegar so I used apple cider vinegar. I also made a rhubarb sauce (cooked down rhubarb and sugar to taste) as a side to the cake. We loved the combo!
I’m so glad to hear that you and your family enjoyed the cake, Julie. The rhubarb sauce sounds like a great addition! :)
Recipe looks awesome! Unfortunately, I’ve cut all of my rhubarb down for the year and it’s waiting to be used in the freezer. About how many cups of rhubarb do you think you used?
Thank you! I’d say you should be fine with 3 cups of rhubarb – that’s what I used. :)
