This black velvet cake is Halloween dessert goals: pitch-black, ultra moist, and full of rich, chocolatey flavor. Made with black cocoa powder (no food dye needed!), it tastes just like an Oreo cookie in cake form.
Adapted from my naturally dyed black velvet cupcakes, the chocolate cake layers bake up soft and tender, then get covered in my favorite silky black cocoa buttercream. It’s a guaranteed bakery-style show stopper perfect for your Halloween dessert table!

Bake Along Instructions (with photos)

1
Make the black cocoa cake batter. Once the batter is mixed, you’ll see a rich black color and a glossy texture, all thanks to the black cocoa powder.
It’s the same ingredient that gives my chocolate Oreo cake with layers of cookies-and-cream frosting its signature dark chocolate flavor!

2
Let the cake layers cool on a wire rack. Meanwhile, you can make the frosting. You want to wait until the cake layers are completely cooled before assembling, or the cake will melt the frosting!

3
Layer the cake layers with the black cocoa buttercream frosting. Once assembled, cover the cake in a thin layer of frosting (crumb coat). Then, chill in the fridge until set.
This keeps the layers firm and prevents them from sliding around while you decorate the cake.

4
Cover the entire cake with the remaining frosting, then decorate with sprinkles. I always make this cake for Halloween, so I use a mix of fun sprinkles like eyeballs and black bats!
Once you’ve had a slice of this cake, you’ll get why I love black cocoa. It’s the same ingredient that makes my dark black cocoa miso brownies with an umami twist so intensely rich and bakery-style decadent!

Skip the bakery run for your Halloween spread because I’ve got you covered with a lineup of treats! My monster cookie bars loaded with peanut butter and M&Ms are perfect for a crowd, while my black cocoa Oreo cupcakes dipped in ganache have the same moody, Oreo-rich flavors and can easily be dressed up for the holiday!

Instructions
Make the Cake Batter
- Line three 6-inch cake pans with a round of parchment paper on the bottoms. Preheat the oven to 350 F/180 C.
- Whisk together the flour, black cocoa powder, baking soda, and salt until combined. Set aside.1 2/3 cup (210 g) all-purpose flour, 1 teaspoon baking soda, 1 teaspoon fine sea salt, 3/4 cup (75 g) black cocoa powder

- Then, whisk the hot coffee into the cake batter until just combined.2/3 cup (145 g) hot coffee
- Evenly distribute the cake batter into the prepared cake pans. This is best done with a food scale for accuracy; each pan should hold roughly 400 grams.
- Bake for 25-35 minutes, or until a toothpick inserted into the center comes out covered in a few moist crumbs. Let the pans cool on a wire rack, then run an offset spatula around the edges and flip them out onto the rack.

Then, mix in the black cocoa powder, heavy cream, vanilla, and salt until combined.2 cups (452 g) unsalted butter, 2 cups (300 g) powdered sugar, 1/2 cup (50 g) black cocoa powder, 3 tablespoons (36 g) heavy cream, 1 teaspoon vanilla bean paste or extract, Pinch of fine sea salt
Assembly
- Place the first cake layer on your serving board. Pipe an even layer of the black frosting on the top. Continue alternating the cake layers and frosting, placing the last layer upside down. Then, cover the cake with a thin layer of frosting to crumb coat. Chill the cake in the fridge for 15-20 minutes, or until the frosting is firm.
- Use the remaining frosting to cover the top and sides of the cake. Decorate as desired and enjoy!Sprinkles for decorating




















Hi,
I do not possess three 6 inch round baking pans. Can I use two 9 inch round cake pans that are about 2 inches deep instead?
Hi Patty! That should be just fine!
