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.

    Hi thanks for sharing this recipe. I am actually looking for a good chocolate cake recipe for my son’s  birthday cake. My family doesn’t like cakes that are too sweet. Normally I will half the sugar but am wondering by doing so…will it effect the texture of the cake?

    1. Jamie says:

      Hi, Elaine! Reducing the sugar could make the cake a little drier. I would suggest adding an extra egg yolk. I hope this helps. Let me know how it turns out!

  2. Frenny says:

    No even joking, I have made this cake 10 times in the last 4 months. So easy and great results. I switched to a bundt pan and it takes 38 min. I also reduced the sugar to about 1.5 cups. Such an awesome post, thanks for posting!! 

    1. Jamie says:

      You’re welcome, Frenny! I’m so glad you enjoy the cake!

  3. Chris chivers says:

    Hi

    Made this fab cake severel times alwats goes down well, can it be cooked in one tin and sliced in two if so how long should I cook it.
    Thanks for recipe happy baking

    1. Jamie says:

      Hi, Chris! I think you can probably bake it in one pan. Just be sure to adjust the cooking times so it’s properly done. I hope you enjoy it!

  4. Angir says:

    Is the coffee part absolutely necessary?

    1. Jamie says:

      Hi, Angir! The coffee is not absolutely necessary, but it really brings out the chocolate flavor in a beautiful way, and you won’t even taste the coffee. If you really don’t want to use it, you could use just water. Let me know how you like it!

  5. Brianna says:

    Hi! I adore this cake and have made it many times, always receiving so many compliments for it! But now I’m hoping to make it in 9″x13″ form and I am wondering how to go about it without drying it out or having an unbaked center. Help? :) 

    1. Jamie says:

      Hi, Brianna! I think the cake with work just fine in a 9×13 pan. Bake for about 35 to 40 minutes, but keep an eye on it. Let me know how it goes!

  6. Jeff @ Make It Like a Man! says:

    This cake looks like it was made with Dutch-process cocoa, and the recipe calls for baking powder (instead of baking soda, or a mixture of the two), which makes me think even more that it calls for Dutch-process cocoa, but the way the ingredient list is worded, it makes it sounds like you’re asking for natural, unsweetened cocoa. Which is it?

    1. Jamie says:

      Hi, Jeff! I used Hershey’s natural unsweetened cocoa powder for this recipe. Let me know if I can do anything else for you!

  7. mini says:

    Hey there!
    What could I replace for eggs?
    Please let me know if you have recipe without eggs. I do not take eggs.
    Thanks mini 

    1. Jamie says:

      Hello, Mini! You can replace 1/4 cup unsweetened applesauce for every egg. I hope you enjoy the cake!

  8. Blen says:

    I was so excited to try this recipe for myself as a friend of mine has been making it for me for years. The excitement didn’t last long, though. I followed the recipe exactly and made cupcakes. First, the batter was not thin and runny; rather it was kind of goopy. (Doesn’t adding the coffee hot temper the eggs a little bit?!) Second, every single cupcake (2 1/2 dozen!) sunk in the middle. The flavor was okay, but it was just okay. So disappointing. I’ll give it one more shot to see if turns out any better.

    1. Jamie says:

      I’m so sorry the recipe didn’t turn out for you, Blen. The coffee should definitely not be added hot, just room temperature to cool. I hope you try it again. Let me know how it goes!

    2. Kristi says:

      I’ve played with this recipe for cupcakes and also had them sink in the middle. After some research I found out that you DO need to add the coffee when it’s HOT! Sounds weird, but it totally worked when I did it that way, cupcakes were not sunk in the middle! I mixed everything together except for the coffee and then left the mixer on low and added the hot coffee so it didn’t screw with the eggs. Maybe give it another go with the hot coffee and see if you have the same luck!

    3. Jamie says:

      Thanks, Kristi!

  9. Salma says:

    This is literally the best chocolate cake i have ever made!! Thank you so much 

    1. Jamie says:

      Yay! So glad you enjoyed it!
      -Jamie

  10. Chloe7 says:

    So sorry, my mistake – I meant to say the 3/4 cup dark cocoa PLUS the 2 tablespoons of BLack Cocoa. Apologies

    1. Jamie says:

      No worries, Chloe! The extra 2 tablespoons is optional, but you can definitely add it for a richer taste. Let me know if you have any more questions.
