Black Onyx Chocolate Cake Recipe

If you’re looking for a luxurious dessert that would grace any occasion, no matter how fancy, then you would be hard pressed to think of anything more opulent than black onyx chocolate cake. Offering an endorphin-inducing festival of sweetness, a cake like this is the kind that makes the mouth water in anticipation of the richness about to come.

You might think that a culinary delight like this would be the preserve of high-end restaurants or premium confectionery outlets in Manhattan, but this gorgeous delight can actually be made in the comfort of your own home and we’re here to help you make that happen!

We’ll get to the steps involved in creating your black chocolate cake shortly, but first, we’re going to take a closer look at one of the most important ingredients that provides the distinctive taste and coloring - black onyx cocoa powder.

Black Onyx Cocoa Powder & What It Offers

While the term black onyx cocoa powder might not be that familiar to you, it’s likely that you already consume it on a regular basis. That’s because it’s an ingredient used in many sweet treats, like the ubiquitous American treat of Oreo cookies. This perfectly demonstrates what happens when it’s baked - it goes completely black, a color that simply shouts decadence and luxury.

Offering a smokey, yet earthy taste - quite different from other varieties of cocoa powder - it provides a variety of bitter, yet pleasant flavors. However, don’t worry about your black onyx chocolate cake being overly bitter, as the sugar we add more than balances things out.

The Ingredients You’ll Need

If you look below, you’ll see that the ingredients are split up into two sections, which is because of the fact that one part is for the cake itself, with the other used to create the rich buttercream filling that complements it so well. Let’s take a look at what you’ll need.

Your chocolate buttercream ingredients:

  • 1½ cups of unsalted butter
  • ⅓ of a cup of black onyx cocoa powder
  • 3½ cups of sifted powdered sugar
  • 4 sections of dark chocolate
  • 1 tablespoon of vanilla extract

Make Your Frosting Ahead of Time

You’ll be needing to make the frosting for your black onyx chocolate cake ahead of time, as it’s best to have it ready at room temperature. What’s more, despite how much you might want to taste your creation quickly, you’ll need to wait until the cake you’re putting it on has cooled, as it’s far easier to spread and achieve even distribution.

The same goes for your buttercream, as when it’s too cold, you’re going to have quite a job piping it or spreading it evenly. Leaving it out of the fridge for a couple of hours before using is best.

Your chocolate buttercream ingredients:

  • 1 cup of (room temperature) unsalted butter
  • 2½ cups of cake flour
  • 1 teaspoon of sea salt (finely ground)
  • 1 teaspoon of baking soda
  • 2 cups of granulated sugar
  • 1 tablespoon of vanilla extract
  • 4 large eggs
  • 1 cup of black onyx cocoa powder
  • 1½ cups of buttermilk

Start With Making Your Frosting

Ok, so now we come to the interesting part, making your delicious chocolate cake! As mentioned earlier, we’re going to start a few hours before we start making the sponge, by making the frosting. We do that by placing the sea salt, melted chocolate, butter and vanilla into a bowl and beating it until smooth.

After this mixture has a smooth texture, add your buttercream and once the whole thing is blended nicely together, put it to the side in a sealed container.

And Next We Create the Cake

The second step in making this wonderful black onyx chocolate cake is to create the sponge and we start by preheating the oven to 325 degrees, before adding grease and flour to two circular cake pans. After this prep is done, we get to mixing, as we blend the sugar, vanilla, salt and butter together for around 5 minutes or until fluffy - whichever comes first.

Next we add the eggs, one at a time, waiting for each to become blended before the next is introduced and then go on to beat the whole mixture for another 2 minutes. After this, we add the flour, baking soda and buttermilk, beating it fully for the last time. Finally, we divide the mixture up into two, pouring equal amounts into your pre-prepared baking tins.

This is then baked for 40-45 minutes in the oven and then left to cool. Once the sponge is at room temperature, the finishing touches involve putting everything together to create an impressive cake that will have people offering their tasting services!
