When it comes to cake, most people in my family are team chocolate all the way! If you’ve ever made Hershey’s Black Magic Cake, you know that this cake is a chocolate lover’s dream come true, so it’s one of the must-make cake recipes around here. 

Black Magic Cake is rich, moist and comes together with ease. I also love that it bakes up perfectly regardless of if you use a bundt pan, two 9-inch round baking pans or a 9×13-inch baking pan. You can frost it, drizzle on a simple ganache, or even dust it with powdered sugar and serve it alongside fresh berries. 

If you love chocolate, this cake recipe is sure to become a family favorite.

WHAT IS BLACK MAGIC CAKE?

Black magic cake is a Hershey’s classic. I can only assume that it’s called a “black magic cake” because it is so rich and chocolatey, and so good it almost tastes like magic.

What makes it so magical?

The cake is super moist, thanks to a combination of oil and buttermilk in the batter. The buttermilk also gives the cake a super tender crumb, so every bite practically melts in your mouth.

The other thing that makes this cake so amazing is strong black coffee in the batter.

Don’t panic if you don’t like coffee. I promise that this cake doesn’t actually taste like coffee at all!

Coffee does this magical thing when it is paired with chocolate; it enhances the flavor of the chocolate and makes it somehow taste even more…well, chocolatey!

Combine these things together and you’re left with a chocolate cake that is even more incredible than the classic Hershey’s chocolate cake.

HOW TO MAKE BLACK MAGIC CAKE

Much like the best chocolate cake, this is one cake that will have everyone begging you to give them the recipe. 

But the real secret is that it’s so simple to make. You don’t even have to use a mixer if you don’t have one!

Ingredients you’ll need

Black magic cake is made with unsweetened cocoa powder. Don’t worry about buying a specific type or brand; I find any unsweetened cocoa powder works well here!

In addition to the buttermilk, vegetable oil, and coffee that we talked about earlier, you’ll also need:

  • 2 cups granulated sugar
  • 1 3/4 cups all-purpose flour
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 2 eggs
  • 1 teaspoon pure vanilla extract

Can you make this cake without coffee?

I know I sound like a broken record, but I really can’t emphasize enough: This can’t doesn’t taste like coffee.

But if you can’t use coffee in the cake or are really opposed to the idea, you can use 1 cup of water instead.

Helpful resources for making black magic cake

If you’re a beginner baker (or even if you’re a baking veteran), I’ve got some helpful posts that you may want to check out as you make this cake.

The first step to baking success is making sure you’ve properly measured your ingredients. Learn how to measure flour to get off on the right foot with this recipe.

If you forgot to buy buttermilk at the store, don’t worry! You can use my simple buttermilk substitute in this recipe instead. (Make sure you save that post because it’s useful for so many recipes!)

Making this cake

I love making black magic cake as a layer cake. Prep two 9-inch round cake pans by greasing and flouring them. This will help the cake layers release cleanly after baking.

In a large bowl, whisk together the dry ingredients: sugar, flour, cocoa powder, baking soda, baking powder, and salt.

In a separate bowl, whisk together the rest of the cake ingredients: eggs, buttermilk, coffee, vegetable oil, and vanilla.

Add the wet ingredients to the dry ingredients. If you have an electric mixer, use your mixer to beat on medium speed for 2 minutes. If you don’t have a mixer, whisk vigorously for 2 minutes.

The batter will be quite thin – don’t worry, it’s supposed to be!

Divide the batter evenly between the two pans and bake for about 30-35 minutes. A toothpick inserted in the center of the cakes should come out with a few moist crumbs clinging to it, but no wet batter on it.

Let the cakes cool in the pan for 10 minutes before turning them out onto a cooling rack to cool completely before frosting.

FROSTING OPTIONS AND TIPS

Personally, I think the ultimate way to eat black magic cake is with homemade chocolate frosting. The double chocolate combo is so decadent – it’s any chocolate lover’s dream!

But that doesn’t mean that’s the only way to finish this cake!

Try my favorite buttercream frosting or cream cheese frosting. Or you could get a bit creative and pair this black magic cake with peanut butter frosting or marshmallow frosting!

Frosting tips and tricks

Because this cake is so moist, it does make it a little more difficult to frost than some other cakes. 

It won’t affect the flavor at all; it just means that you might end up with some crumbs in your frosting if you don’t think ahead a bit.

For a really clean look, do a crumb coat on this cake. Freezing the cooled cake layers for 1-2 hours will also make them easier to frost cleanly.

CAKE STORAGE

Store this cake covered at room temperature for up to 3 days. It will stay nice and moist – no dried-out chocolate cake leftovers here!

If you choose to use a cream cheese-based frosting, make sure to store the cake in the refrigerator instead of at room temperature.

Dig into a slice of this black magic cake with a big, cold glass of milk and enjoy pure chocolate cake bliss.

    WOW! is all I can say – I will smother this bad boy in a butter based dark ganache. I’m a little confused pardon me, but thank you for this! 
    I saw this cake exactly – don’t know where – and the recipe is exactly the same – I think it’s yours both times??? BUT the other recipe asks for 2 tablespoons of Black Cocoa? Isn’t that what makes this cake the thing that it is? Cheers and all the best.

    1. Jamie says:

      Hi, Chloe! I’m not sure about the other recipe, but 3/4 cup of black cocoa gives this cake a gorgeous dark chocolate flavor. Two tablespoons might not be enough in this regard. I hope you enjoy it!

  2. Kimber french titter says:

    Also a trick to sour the milk is a half teaspoon of vinager in the milk a so sifting the flour makes a big difference in the quality of the cake

    1. Jamie says:

      Kimber: great idea!

  3. Kimber french titter says:

    My mom made that cake 4 years she was born in 1921 the icing she used was homade cream cheese icing it’s my favorite cake

    1. Jamie says:

      Kimber: I love that! Mom’s cakes are always the best.

  4. lynn says:

    :(  I don’t get it. I made this, baked it for the minimum time suggested and it was the most mediocre chocolate cake I’ve ever eaten. Very dry, not at all moist. I made it with Alton Brown’s chocolate ganache, which is delicious and that was the only good thing about it. I may try it again and turn down the baking time, but it wasn’t burnt so I have no idea what everyone is raving about. Oh well….on to the next…

    1. Jamie says:

      Hi, Lynn! I’m so sorry you didn’t enjoy the cake. I hope I might have another recipe that works out better for you. All the best to you.

  5. Jack W says:

    I have made this delicious beautiful cake a couple of times for friends and it’s just perfect.

    And don’t you dare skimp on that ganache. That’s the part that separates the men from the boys.

    If you want to get big hugs, this is how you get big hugs.

  6. Susan says:

    This recipe is amazing!! It is my go to chocolate cake recipe. I’ve made it as cupcakes too and it turns out awesome. I like to put just a simple homemade whipped cream frosting on top and it is to die for. 

    1. Jamie says:

      I’m so glad you enjoyed it, Susan!

  7. Lyndsi says:

    Sounds wonderful. I will be making it tonight!

  8. Christine says:

    what recipe did you use foe the frosting

  9. Courtney says:

    replace the buttermilk with coconut milk. you will never use buttermilk again!

    Hello,

    This cake is also a favourite in my circle! I stumbled upon the recipe in an old recipe book of my grandmother’s-you know the church group compilations of simple but delcious favourites among congregationalists. There was a gold foil star beside the recipe-my grandmother’s way of indicating that the recipe was a great success and must be remembered for future use. This was all the encouragement I needed! I made the cake to complement the dessert menu of a boutique restaurant, and guests just raved about it. There is something to be said for simplicity and the wisdom of our elders (were my grandmother here today I would suggest she add another gold star to this jewel of a recipe). Thereafter I received several requests to make the cake to order! As the recipe was not my own I was happy to share it with any who requested more information. Since then, my family and friends have come to prefer this cake for birthdays and Sunday dinner events. I’m happy to see that others have enjoyed it as much as we have!
