The best vegan chocolate cake topped with the richest silkiest vegan chocolate buttercream frosting. Perfectly moist and totally decadent.
I can’t get enough of vegan chocolate cake. It’s definitely a favorite.
And I got all arrogant with this one and called it ‘the best vegan chocolate cake’ you know, as you do.
It’s mega-chocolatey, wonderfully moist, and supremely simple using ingredients you probably already have in your pantry. Crazy simple with a spectacular outcome.
And the frosting – oh my word – the frosting.
It’s the silkiest creamiest vegan buttercream I have ever made. And paired with this two-layer decadent dream cake and topped with chocolate shavings you’ll make every chocolate lover a very happy camper with this cake.
I have already tested this cake on some non-vegans who had no idea that it was a vegan cake and they were freaking out over it. Now that’s what I like to see.
Cake Pan Sizes
What I love about this cake is that it’s a 9 inch two layer beauty that can also be made in 8 inch pans.
And since I get a lot of questions from readers asking for different size cake recipes, I was thrilled to discover that this is an either/or situation for 8 or 9 inch pans with absolutely no other adjustments.
If you make it in 9-inch cake pans, as we did for this photoshoot, it is totally gorgeous. If you make it in 8-inch cake pans, it’s just taller but every bit as gorgeous.
How To Make the Best Vegan Chocolate Cake
You will find full instructions and measurements in the recipe card at the bottom of the post. This is a summary of the process to go along with the process photos.
- This is a simple 10-ingredient recipe that takes very little time to prepare.
- Sift the all purpose flour and cocoa powder (unsweetened) into a mixing bowl. Add the sugar, baking soda and salt.
- Make up some vegan buttermilk by adding some lemon juice to a measuring jug and then pouring in soy milk, or almond milk, and letting it curdle into vegan buttermilk.
- Add the vegan buttermilk to the mixing bowl and some vanilla, vegetable oil, vinegar and applesauce and mix in. Use a hand whisk briefly to get rid of any big lumps.
- Spray two 9-inch (or you can use 8-inch) baking pans with non-stick spray and then line the bottoms with circles of parchment paper.
- Divide the batter evenly between the cake pans and then bake for 30-minutes. Let the cakes cool for a few minutes in the cake pans and then transfer them to a wire cooling rack to cool completely before frosting.
That Vegan Chocolate Buttercream!
The frosting is an ultra rich vegan chocolate buttercream. It’s only 6-ingredients and ridiculously simple to make, but it’s extremely impressive.
You can just add all the ingredients – vegan butter, powdered sugar, cocoa powder, salt, vanilla and non-dairy milk to a mixing bowl and then use your stand mixer to whisk it into a smooth and creamy vegan chocolate buttercream.
It makes quite a lot of frosting, but as you can see from the photos, probably the perfect amount really.
Unless of course you’re not a fan of frosting in which case, I don’t even know what to do with you?
Only joking. If you’re not a frosting fan, this is a cake that can be served plain or with just a sprinkle of powdered sugar or with some vegan whipped cream.
When the cakes are completely cool, spread on the frosting.
And decorate with vegan chocolate shavings.
Just a note that if you’re making this as an 8-inch layer cake, then it’s almost too much frosting. So you might want to reduce a little bit, or just have it on extra thick, which is what I did when I tested this for 8-inch pans.
Ingredient Tips
Vegan buttermilk. This creates a super moist and tender crumb. It’s a little more moist than the average sponge cake, but not overly so. It’s rich and decadent and exactly how you want it to be. I prefer soy milk for making vegan buttermilk because it’s thicker and richer. Almond milk is more watery, but you can use almond milk if you can’t use soy.
Take a look at our vegan buttermilk post which also features a video where you can see the difference in texture between vegan buttermilk made with soy milk vs almond milk. Coconut milk won’t curdle but can be used in a pinch.
Canola oil. I use oil rather than vegan butter in most of my cakes and I really love the result. For this cake I used canola oil, but I have also tested this with my other, rather unusual favorite, which is extra virgin olive oil. You can also use vegetable oil. If you want to use coconut oil then make sure it’s melted first.
Applesauce. This creates moisture without needing to use more oil and is also an ‘egg replacement’ of sorts.
Flour. Regular all purpose flour is my flour of choice for this cake. I recommend you weigh it for the best accuracy. Flour measures are tricky, and even for experienced bakers using the spoon and level method (the correct method when using cup measures for flour) it is possible to get it a bit wrong. And baking is very precise and can be a little unforgiving in that respect.
Cocoa Powder. I use natural unsweetened cocoa powder. This works great in the cake and the frosting.
Recipe FAQ
Applesauce! But I don’t find ‘egg replacements’ to be crucial in vegan baking, though I do use them for flavor/moisture. Really it’s more the vinegar/baking soda combination that is crucial in this cake. The applesauce is more for moisture than anything else.
You can use 1 ½ flax eggs. So you would mix 1 ½ Tablespoons of ground flaxseed meal with 4 ½ Tablespoons hot water and let that sit until it becomes thick and gloopy.
The vinegar reacts with the baking soda and helps the cake to rise. I used distilled white vinegar, but you can use apple cider vinegar too, they are interchangeable.
Sure, you can try this with a gluten-free all purpose flour blend, in the same quantity as the regular flour.
This recipe as is will make 18-24 cupcakes. If you want to make a perfect batch of 12 cupcakes though then check out our classic vegan chocolate cupcakes recipe.
Storing and Freezing
This cake will keep covered at room temperature for 3-4 days and in the fridge for up to 7 days. It is definitely at its best in terms of taste and texture the day of baking and the following day.
Unfortunately, you can’t make the batter in advance and let that sit in the fridge for a few days as that can cause the cake to not rise. It’s a make and bake immediately situation but the cake itself does last a fair while.
You can also freeze this cake, either frosted or unfrosted, for up to 3 months. Let it thaw overnight in the fridge when you’re ready for it.
This Is The Best Vegan Chocolate Cake Because:
- It’s wonderfully moist! Yes, I keep saying it but it really is.
- It’s extremely chocolatey. The chocolate flavor really pops.
- It’s so rich and decadent. You’ll be super satisfied after a slice of this.
- It’s really quick and easy. The hardest part about this cake is having the patience to wait for the layers to cool so you can frost it and eat it!
- Vegans and non-vegans are mad about this cake! Tried and tested and definitely true.
- It can be made in 8-inch or 9-inch pans! I have tried it both ways and it worked great. The photos are of the 9-inch cake, but 8-inch works perfectly as well the cake is just taller.
- The vegan chocolate buttercream is totally divine. It’s really the perfect topping for this cake, oh and don’t forget the chocolate shavings!

Notes

- Nutritional information includes everything, frosting, chocolate shavings, all of it!

Happy to hear you enjoyed the recipe Kelly! Thanks so much for your great review!
Hi Alison
Having used this recipe several times and everyone loving it! I am planning on using it for a wedding cake for September.I know you have had several queries regarding cake tins and I have used both an 8 inch and 9inch tins previously.I am aiming for possibly 3 tiers
Although I haven’t decided yet.Have you used other round tins or can you advise me?It is my third wedding cake but I tend to follow recipes so am not sure re. quantities! I am thinking a ten inch ,8inch and 6inch.I will do a separate gluten free small cake from your site hopefully although I have not tried that yet!Also have you frozen the un iced cakes?
Thank you
I don’t like American buttercreams so I’ve never made this frosting but this really is THE BEST vegan chocolate cake recipe. If you’re reading the reviews to help you decide, I promise you this is the one. I use this recipe frequently and I get rave reviews every single time. The only change I make is to add a teaspoon of a espresso powder to enhance the chocolate flavor and I go just a teeny bit light on the oil because it’s crazy moist.
Wow thanks so much for your amazing review Amanda! Happy to hear you enjoyed the recipe!
Thanks, once again, for a reliable and delicious recipe. I usually use your vanilla cake recipe but my daughter wanted chocolate. Simple ingredients, easy to make and delicious!
Thanks so much for your great review Julia! Happy to hear you enjoyed the recipe!
it’s says 1/2 cup of oil. what mls is this please?
Thanks for pointing that out Edel. It’s 120ml.
I made this cake over Christmas and it was very popular amongst my non-vegan family! They couldn’t believe it was vegan. Absolutely delicious, I added a few tablespoons of soya yoghurt for a bit more moisture, couldn’t fault it at all, fantastic recipe. Highly recommend!
Thanks so much for sharing and for your great review!
Hi! I was just wondering if I could make the frosting in advance? I was thinking of baking the cake and making the frosting and assembling and then doing a crumb coat the day before decorating but want to make sure the extra frosting for decorating can be kept in the fridge along with the assembled cake? So excited!
Hi Amanda, you can keep the frosting in the fridge overnight. Be sure to whip it up again to soften it up a bit before frosting your cake.
This is the best cake I’ve ever made. I’m not even the biggest chocolate cake fan, but it turned out perfectly. I’ve made several of the cakes from this blog over the last couple of years (including the lime cake for my birthday and the strawberry cake for my partner’s), and they’re always amazing. I don’t even bother looking for vegan cake recipes on other sites anymore, because they’re never as reliable, easy, and delicious as Loving It Vegan’s.
Thank you so much for your kind words! So happy to hear you enjoy the recipes!
