  • 1 cup (240g) buttermilk, room temperature
  • 1 tsp. McCormick vanilla
  • 1 tsp. vinegar
  • 1 oz red food color
  • 2 cups (450g) granulated sugar
  • 1 cups (224g) vegetable oil, or olive oil
  • 2 large eggs, room temperature
  • 2 1/2 cups (320g) cake flour
  • 1/4 cup (32g) good quality cocoa powder
  • 1 1/2 tsp. baking powder
  • 16 ounces bittersweet chocolate
  • 12 ounces heavy cream
  • 2 sticks butter, unsalted
  • 2 cups (250g) powdered sugar
  • 1 (7oz) jar marshmallow fluff
  • 2 teaspoons clear vanilla extract
  1. Heat oven to 350°F. Prepare three 8-inch round baking pans by spraying with baking and lining with parchment or spreading GOOP and lining with parchment.
  2. In a 2 cup measuring cup (or medium bowl) pour buttermilk.
  3. Add the vanilla, vinegar, and red food color to buttermilk and whisk to fully combine. Set aside.
  4. In a large bowl add sugar, oil, and eggs and whisk together by hand until it is smooth and light yellow.
  5. Add cake flour, cocoa, and baking powder to the sugar mixture and whisk until just combined.
  6. Now add the buttermilk mixture and whisk until just combined. You do not want any lumps, but I do recommend being gentle with this batter.
  7. Pour about 1 3/4 cup batter into each pan and bake for 22-32 minutes. When using my convection oven I will bake these at 325°F for 22 minutes. The cake is done when it does not appear wet on the top and if you press your finger gently in the center of the cake it feels firm.
  8. Allow to cool in the pan for about 5 minutes, then invert onto a cooling rack. Chill cakes until ready to assemble.
  1. Chop chocolate into fine chips (or use a bag of chips) place in heat-safe bowl.
  2. Heat cream to a soft rolling boil then pour over chocolate.
  3. Stir and cover with saran wrap. Let sit anywhere from 1 hour to overnight.
  1. In a bowl, add room temp. butter and sugar together. Mix until fluffy.
  2. Add marshmallow and vanilla, and mix well.

Boo-tiful Halloween Cake Recipe

There are three main parts to my Boo-tiful Halloween Cake. There are the ghosts, of course–BOO! Then, there is the ganache layered over the all-important red velvet cake. I will break down each of the parts so it’s not so scary to make😉.

  • Red food color
  • Sugar
  • Vegetable oil–You can also use olive oil if that is what you have on hand.
  • Eggs–Room temperature eggs work best for baking!
  • Cake flour
  • Cocoa powder
  • Baking powder

Ganache Ingredients

  • Bittersweet chocolate
  • Heavy cream

Frosting Ingredients (for your ghosts)

How to Make a Boo-tiful Halloween Cake

Let’s start with the all-important Red Velvet Cake. This cake has been around forever and started out with simple ingredients like cocoa, buttermilk, and vinegar. The red color was added later, resulting in the vibrant colors we see today. For this recipe, I recommend using the highest quality ingredients. You could use a special dark cocoa or apple cider vinegar or extra rich vanilla which would all impact the flavor. I recommend making your own homemade buttermilk for this recipe! While the cake is baking, heat the cream to pour over the chocolate for your ganache. This will be the chocolaty goodness your ghosts will sit on!

How to Make your Ghosts (Frosting)

Before you make your ghosts, you need to mix the ingredients together to make the frosting. Then, I used a piping bag fitted with a 2A (large open round) tip. I used this tip to create my ghosts. It is not essential to use a 2A tip, you can achieve a similar effect by just cutting off the tip of the piping bag. You can make your ghosts as big or small as you want them to be!

How to Bring the Ghosts Alive!

I used a bit of my glaze icing and added some scary (or not so scary) expressions to the ghosts. Ok, ok, so they aren’t scary. My kids even laughed at me. But I sorta liked them. Just mix 1 cup powdered sugar, 1 tablespoon milk, 1 tablespoon corn syrup, and 1-3 drops of lemon juice together. You can add more milk if you need to. Have fun with giving your ghosts facial expressions!

And there you have it! Boo-tiful Halloween Cake is a boo-tiful and fun cake that is sure to be the hit of any Halloween celebration!

  • Amanda Rettke says:

    lol Yes, the question was answered, but as my commenting system doesnt let me insert answers below the specific question, it is often hard to find and understand. So I just respond to each question individually!
    It is plain ole vanilla frosting below the ganache. 🙂

  • Amanda says:

    Okay…so I made the cake for my son’s birthday party last weekend. Turned out great! Though my ghosts were a little floppy! Check out my version:

  • grace says:

    the best part of this is that the innards are blood red. a close second is your more-adorable-than-scary batch of ghosts. 🙂

  • Kathleen B says:

    This is SPOOK-TACULAR!!(sorry, corny) One question, does it need to be refridgerated? I am traveling from AL to SC for Halloween and would love to bring this along, but can’t if it has to be kept cold. Thank you!!

  • Jenroxy1 says:

    Wow this cake is amazing 🙂 I am nowhere near as seasoned as you, baking is a hobby of mine but I am going to attempt this cake for a Halloween party at work. Hoping it comes out half as good as yours 🙂 How did you apply the expressions to the faces of the ghosts?

  • Jenny says:

    This is so so so amazing!!
    I am going to feature it on my blog soon — come on over and check it out

  • Joy says:

    I LOVED THIS ICING AND GANACHE!!!!! I didn’t get a photo of the cake before it was eaten, but here’s the leftover slice it’s on my 365 Photo Challenge blog. (and if you just go to and scroll down, you can see some carved pumpkins from the party) =o)
    Thanks for the inspiration!
    speaking of inspiration, you’re bat cake top with the tree and moon are what inspired my pumpkin that I carved =o) THANK YOU!!

  • Carrie Triner says:

    I’m going to attempt to make this AWESOME Cake for the ladies that work for me.
    wish me luck!

  • Carrie Triner says:

    I have a question.
    Do I spoon or pour the Ganache on cake.
    Are the ghost piped ontop of the cake?
    Or do you pipe them on parchment paper and transfer to cake?
    Do the ghost harden up.
    I’ll be traveling with this cake.
    I need all the help I can get here.

  • Jaime says:

  • Jojo says:

    Loved your boo-tiful cake.. i used that concept to make mini cupcakes that turned out so adorable.. i can’t wait to see what everyone at the party thinks of them… you can check out the pics of your idea on my little blog at
    thanks for the inspiration!

  • Amber says:

    I tried the front the frosting you used for the ghosts. It is absolutely wonderful. I love it.

  • janet says:

    This is really neat. I thought the ghosts were meringue-marshmallow fluff. I’m thinking big cupcakes in red velvet done the same way.Thanks for the inspiration!

  • Lindy@Itsy Bitsy Paper says:

    This is a great cake! I featured it on Fun Friday Finds today. I hope you can stop by and grab a featured button if you’d like.

  • Deanna says:

    “Orange Velvet” would be amazing inside this! Or orange piped pumpkins on top!

  • Breanna Clifford says:

    I attempted to make this cake today, it doesn’t look as good as yours does though!!! I had a problem with my ghosts falling over, maybe next time a will add a little more powdered sugar to stiffen it up a bit.
