Halloween Cake

I was testing out an idea for my book and whipped up this cake. It’s my favorite chocolate cake, covered in milk chocolate ganache with chocolate-covered donut holes on top. I couldn’t stop there, so I sprinkled some sugar and stuff on top of the donuts to add more sweetness!

Donut holes to top Halloween Cake

Halloween Cake Recipe

There are two main parts to this recipe that you will have to make–the perfect chocolate cake and the chocolate ganache. Yes, there are three parts to the whole presentation, but I simply went out and bought donut holes to add to the top of the cake. If you are feeling up to it, you can always make your own cake pops, too. I just wanted to have more time to make other delicious Halloween treats, like my Pumpkin Buttercream Cupcakes with Chocolate Halloween Toppers!

What makes chocolate cake recipe so perfect? First off, it is inspired by Hershey’s chocolate cake recipe which is the same recipe my grandma used. They added coffee to their cake which does magical things to chocolate. Second, this is truly a MOIST and flavorful chocolate cake. Is there anything worse than dry cake? Nope. You will never have that problem with this recipe!

I used two 8-inch pans for my cake, but you can also use 9-inch pans. If using 9-inch, you will want to decrease the bake time by up to five minutes. And don’t forget to use GOOP to prepare your pans… it is the BEST!

1. Yes, you cannot leave it out.

2. I mean it.

Ok, ok, so you can if you want. But here is what the coffee does… it enhances the flavor of the chocolate. The cake does not taste like coffee at all… it simply tastes richer.

If you simply must not use coffee, you can substitute hot water.

How to Make Halloween Cake

Making the Perfect Chocolate Cake

First, I recommend reading through the ingredients and making sure everything is out and ready. The eggs and buttermilk should be room temperature so getting them out of the fridge ahead of time will solve that for you. If you haven’t already, I recommend making your own homemade buttermilk to have on hand for all your recipes that call for it.

Make sure dry ingredients are sifted and measured properly. When measuring flour, get out your container or bag. Open it and use a fork to stir it, or sift it, loosening it up. Spoon the flour into a dry measure cup then use the back of a knife to level the cup off. (Or you can measure your ingredients on a scale.)

Use the proper tools. For instance, this recipe used a stand mixer. You can use a hand-held mixer (or even stir by hand) but make sure the ingredients are fully mixed and incorporated before moving on to the next step in the recipe.

Use the best quality ingredients if you are able! Dark cocoa’s or high-quality cocoa, fresh eggs, and good quality vanilla make a difference! Feel free to upgrade to all organic ingredients. When it comes to substitutions though, I do recommend making the recipe as-is first, then altering it to make it yours.

Preparing the Ganache

Bring your heavy cream to a boil and pour it over your chocolate chips, mixing it together until the chocolate has melted. Pour the ganache over the cake and top it off with the donut holes.

I ‘faked’ the cake pops on top of the cake because I was too lazy to make another cake just to see how this would look.  The donut balls are a convenient substitution, but as you can see are very lumpy and not as visually appealing as the real thing.

I really enjoyed the flavors.  I mean, it’s chocolate cake with chocolate frosting and chocolate-covered devil’s food donuts.  Who wouldn’t like all the chocolate deliciousness?
