Dark chocolate cake with chocolate frosting.

This rich, moist, and fudgy black magic cake is super dark and rich thanks to black cocoa powder. A light and fluffy whipped chocolate ganache frosting tops it perfectly.

This cake is so dark and chocolatey, it has to be called black magic cake.

Get more info on all the ingredients in the recipe card at the bottom

Flour, sugar, cocoa powder, oil, eggs, vanilla, buttermilk, baking powder, baking soda and salt.

Oil- vegetable or canola oil.

Eggs- large.

Buttermilk- can substitute whole or 2% milk.

Cocoa- dark cocoa powder, unsweetened plus half black cocoa powder (for coloring and richness).

Sugar- granulated white sugar.

Frosting Ingredients

Heavy cream, chocolate chips and salt.

Heavy cream- full fat heavy whipping cream.

Chocolate chips- semi sweet.

How to Make a Black Magic Cake

Preheat the oven to 350 degrees Fahrenheit. Grease and flour two 8 inch round cake pans, or one 13x9 inch cake pan.

Two round, greased and floured cake pans.

In a large bowl, mix the flour, sugar, cocoa powder, baking powder, baking soda and salt together.

Flour, sugar, baking powder, soda, salt and cocoa mixed together.

Then, add the wet ingredients- eggs, buttermilk, vegetable oil and vanilla extract to the bowl that has the dry ingredients and mix until just combined.

A bowl of chocolate cake batter

Pour the mixed chocolate cake batter evenly into the cake pans so that it's level.

Chocolate cake batter poured into two round cake pans.

Bake the cakes for 24-28 minutes or until done.

The cake is done when the top springs back when gently poked, or when a toothpick inserted into the center comes back with moist crumbs.

Cool the cakes at room temperature. Once cooled down, they can be removed from the round pans and covered with plastic wrap and set on wire racks until you're ready to frost them. 

Cover with plastic wrap once they are completely cooled until you are ready to frost them.

To make the whipped chocolate ganache frosting, heat the heavy cream until almost simmering, either in the microwave or on the stovetop.

Pour the hot cream over a small bowl containing the chocolate chips and black cocoa.

Allow the cream and chocolate chips to sit for 5 minutes to melt the chocolate chips.

Sprinkle in the salt and stir until smooth.

Melted chocolate chips mixed with heavy cream and salt.

Cover the melted chocolate ganache mixture with plastic wrap, and refrigerate for at least one hour until it becomes firm, like the consistency of a thick pudding.

Use an electric mixer to beat the chilled ganache until light and fluffy. Don't over mix or it can separate.

Frost the cakes as desired. For two round cakes, frost the first layer before topping with the second layer so that there is a layer of frosting in between. Then you can frost the top of the cake.

Storage

Store cake at room temperature for up to twelve hours, or in the refrigerator for up to 3 days.

Can you freeze black magic cake? 

Yes, you can freeze a cake with ganache frosting. Before freezing, make sure to wrap the cake tightly in plastic wrap and place it in an airtight container. This will protect your cake from freezer burn and will help keep it moist.

When you are ready to eat the cake, allow it to thaw in the refrigerator for several hours before serving.

Tips and Variations

  • If you aren't able to obtain black cocoa powder, you can use all regular dark chocolate, unsweetened cocoa powder. You'll still end up with a delicious black magic chocolate cake! 
  • If you don't have buttermilk, mix 1 cup of regular milk with 1 tablespoon of lemon juice or vinegar, stir and let sit for 5 minutes until thickened.
  • For a more spreadable, light whipped ganache frosting increase the heavy cream to 4 cups.
  • If you don't want to use this frosting for the black magic cake recipe, you can use a different frosting recipe. This will change the look and overall flavor of the cake. A fun option would be a cream cheese frosting and could be colored or a chocolate buttercream if needed.
  • Serve this divine black magic cake with a large scoop of vanilla ice cream for a decadent treat. 
  • I suggest using an offset spatula to help spread the ganache in between the cake layers. 
  • Adding some cherries to the top of this moist chocolate cake makes it the best chocolate cake recipe out there. Cherries go soooo well with the flavor of the chocolate cake and the deep chocolate taste you get with from the combo of the cake and frosting.

What type of pans are best for baking cakes in? 

The best pans to use for baking cakes are usually made of aluminum or metal because they conduct heat better and ensure an even bake. Non-stick pans are also great as they help with ease of removal.

For a round cake, a bundt pan may be another fun option that will create beautiful ridges when the finished cake is removed.

Keep in mind that dark pans may cause your edges to brown up before the center of the cake is actually finished baking. Your baking time may vary depending on your pan of choice.
