This black velvet buttermilk cake is super soft, moist, and oh-so-dark. The secret to an ultra-dark color is black cocoa powder! Similar to my incredibly popular red velvet, white velvet, green velvet, and pink velvet cake recipes!
This is the best black velvet cake because it's rich, chocolately, and has that classic velvet texture and flavor. Velvet cakes have a very soft and tender crumb (hence the name) and is different than a traditional chocolate cake. Thanks to a little buttermilk that tenderizes the cake, every bite is full of delicious chocolate flavor.

Black velvet cake ingredients
Black cocoa powder is the most important ingredient in black velvet cake. This is the same type of cocoa powder they use to make Oreo cookies and has a very distinct flavor. It's also alkalized and has less fat content than dutched cocoa powder or natural cocoa powder so we are using a little more fat (oil) in this recipe to make up for that.
If you don't have black cocoa powder, you can use dutched cocoa powder, which will perform the same way as black cocoa powder, but the color won't be as dark, and the flavor will be a bit different. You can make up the color by adding in a bit of black food coloring.
Did you know not all cocoa powder is created equally? You might read our blog post on cocoa powder to find out more about how using dutched or natural cocoa powder can really affect the final cake!
How to make the cake layers
- Adjust an oven rack to the middle position and preheat to 350ºF/176ºC.
- Grease three 8" cake pans with cake goop or your preferred brand of pan release.
- In a medium-sized bowl, whisk together the melted chocolate, cocoa powder, hot coffee, vanilla, and oil until combined (it will look lumpy).
- Then mix in the warm buttermilk until everything is combined. Set it aside for now.
- Add the softened butter to bowl of your stand mixer with the paddle attachment attached and beat at medium-high speed until smooth and shiny, about 30 seconds.
- While mixing on low, gradually sprinkle in the sugar. Continue mixing until the mixture is fluffy and almost white, about 3-5 minutes.
- While mixing on low, add the eggs 1 at a time, mixing in fully before adding the next egg.
- Whisk the flour, baking powder, baking soda, and salt in a medium bowl.
- While mixing on low, add in ⅓ of the flour mixture, then ⅓ of the chocolate mixture. Repeat two more times.
- Stop to scrape the bowl after all the ingredients have been added and mix them for 15 more seconds to make sure everything is combined. Don't over-mix.
- Divide the batter evenly between the prepared pans. Smooth the tops with a rubber spatula.
- Bake the cakes until they feel firm in the center and a toothpick comes out clean or with just a few crumbs on it, about 30-35 minutes.
- Transfer the pans to a wire rack and let them cool for 20 minutes.
- Invert the cakes onto the rack and pop the cakes out of the pans. I freeze my layers for about 1 hour before frosting them, which helps lock in the moisture.
How to decorate your first cake
How to make the frosting
- Cream your softened butter until smooth with the whisk attachment (by hand or in the stand mixer is fine)
- Add in the vegetable shortening to the butter and cream it until it's smooth.
- While mixing on low, start adding in your sifted powdered sugar one cup at a time until it's all combined with the butter mixture.
- Add in your salt, vanilla, and, milk and whip on medium for 10-15 minutes until the buttercream is very light and fluffy.
- If your frosting is too thick, you can add in 1-2 more Tablespoons of water or milk to thin it down to your desired consistency.
- You can now add in your desired food coloring if you prefer your frosting to be colored. I used electric pink, electric green, and electric yellow food coloring. Remember, the frosting color will deepen after 24 hours. You can also make the frosting black if you want by using super black food coloring instead and using chocolate frosting as your base.

Hi! I just got halfway through measuring out my ingredients, and 16oz of sugar seems like so much / just validating that's the right amount?! So sorry to bug, just fact checking before I proceed!! Thank you so very much!!
The Sugar Geek Show says
Yes it's correct
Meme says
I have been doing, this cake recipe for a quiet sometime, but the last time I made it turn out very dry, do you have any idea, what could be the issue?
The Sugar Geek Show says
You may have over-baked it or it was cold and it seemed dry because the butter im the cake was cold
RefIlwe Chilisa says
Metrics measurements please! I so want to try this ONE! Tia

I cannot find Dutch process cocoa ANYWHERE within 40 miles. Is natural cocoa ok to substitute?
The Sugar Geek Show says
Hershey's make a special dark cocoa powder or you can buy it online.
Nicole says
When using this recipe for cupcakes, they never fluff/dome. The cupcakes always fall flat.
Do you recommend a certain oven temperature, omitting/adding ingredients?
Thank you so much in advance!

This recipe used to say 16 ounces of butter. I’m guessing the 6 ounces it’s now at is the correct amount?
The Sugar Geek Show says
Yes that was a typo
Nicole says
Well I’ve made this recipe countless times with 16 ounces ? of butter and it still turned out delicious. It’s even still carvable.
Whoops.
Anu arun says
Can u plz put these recipes in cup measurements.that would be very helpful for me to do.tks
The Sugar Geek Show says
All my recipes are by weight so that they turn out. Baking with cups is not accurate and could result in a baking fail and wasting of expensive ingredients.
Evelyn Keplinger says
What is the beautiful pink filling?
Nikki H says

Shabna Anwar says
Hi, lovely cake recipe. I have only one 6" pan, so I can I bake it at 3 internals. Hope it doesn't matter if the batter is outside until one pan is baked m then bake the second n third batter.
Lynne says
What do you recommend for a filling?
Simone dela Calzada says
When I made this cake the sides shrunk except the bottom of the cake. Do the sides came out not even. I greased l and flour the pan. What did I do wrong? It always with chocolate but not the vanilla. Still delish tho. Your reply is greatly appreciated.
The Sugar Geek Show says
Either over-baking or over-mixing causes the sides of a cake to shrink.
Marian says
Do you use a simple syrup on your cakes or would you just use the simple syrup as as a spritze to adhere fondant to cakes? I'm a newby, learning so much..
Thanks you guys
The Sugar Geek Show says
I don't use simple syrup for anything
Ashleigh B says
Omg this cake looks sooooo delicious! Could you please tell me how many ‘servings’ would be needed for a 1/4 sheet cake pan? Thank you! 🙂
The Sugar Geek Show says
I usually do a double batch and a half for a quarter sheet
Refilwe Chilisa says
I would love to try it out and I need metrics measurements for this please.. Tia xx
Michele says
1oz=28gr 🙂
Hani says
@tia hi, if you look under ingredients, just below vanilla, you can see metric. Touch it and all the US customary will change to metric.
