About The Recipe

There is a chill in the air and we’re a little over a week away from Halloween. My mom and I have had SO many ideas for Halloween treats this year to share with you all. From simple treats like our Monster Cookies to more elegant, and dare I say…spooky treats like this cake!

And while we have so ideas, I think this cake might just be one of my absolute favorites thus far.

A few nights ago, my mom and I watched the newest Haunted Mansion. Between you and me, I was skeptical. I adore the 2003 film and didn’t think I would enjoy the new one (I mean, I just have SO much nostalgia for the OG film!).

I was SO wrong. Within minutes of the movie starting, I was sucked in. It gave me so much inspiration for this cake!

I wanted to make something that was truly spooky, but still pretty.

So, we whipped up some cookies, bought some edible glitter, and went to decorating! It honestly was such a breeze to decorate. We had so much fun!

And, I honestly think that it came out SO CUTE.

Just think, three layers of rich, moist, and easy-to-make chocolate cake (all you need is a bowl and a whisk!) and frosted with a silky smooth chocolate buttercream.

The best part? This cake is made with simple ingredients, naturally dyed black, and comes together in less than an hour.

It’s a cake that is sure to impress, while being so simple that it seems almost like magic.

What is Black Velvet Cake?

A black velvet cake is like a delicious cross between a rich and deep dark chocolate cake and a red velvet cake. It’s kind of the best of both worlds! Though, the secret to it’s deep color is not food coloring, but actually black cocoa powder.

This is what adds the deep and rich chocolate flavor, while also naturally coloring the cake (and frosting!).

Equipment Needed

Ingredients

Full ingredient amounts and instructions can be found in the recipe card at the bottom of the post.

For The Cake:

  • Black Cocoa Powder – This is the secret to this utterly delicious cake. Not only does this add a rich and decadent chocolate flavor, but it also naturally dyes this cake black!
  • Boiling Water – To intensify the chocolate flavor, we bloom the cocoa powder.
  • All-Purpose Flour – Skip the cake flour! Regular all-purpose flour gives this cake the perfect structure and texture.
  • Granulated Sugar – Gives this cake just the right amount of sweetness.
  • Baking Powder – Leavening is essential in baking! This provides the perfect rise in the cake to give is a light, tender, and delicious texture.
  • Baking Soda – For this recipe, we add a dash of baking soda to ensure the rise of this cake, as it does have an acidic ingredient!
  • Salt – Cuts the sweetness and helps enhance the flavor.
  • Large Eggs – Remember to set our your eggs ahead of time to allow them to come to room temperature before mixing.
  • Buttermilk – Using buttermilk in a cake does SO MUCH! From creating a more tender crumb, to activating the leavening, and even making the cake itself a little richer.
  • Vegetable Oil – Makes this cake extra moist and oh-so tender.
  • Vanilla Extract – Adds a depth of flavor to this cake.

For The Frosting:

  • Salted Butter – We always recommend that you use salted butter for frostings, as it helps enhance the flavor of the frosting and cuts some of the sweetness. Though, if all you have is unsalted, you can use that. Just add a pinch of salt!
  • Powdered Sugar – Be sure to sift the powdered sugar, as lumps in the powdered sugar can mean a lumpy frosting.
  • Black Cocoa Powder – Adds an intense chocolate flavor to this frosting, while also coloring it naturally.
  • Whole Milk – Using whole milk in this frosting helps loosen it to make it spreadable.
  • Vanilla Extract – A splash of vanilla to give this frosting a delicious undertone.

FAQ’s and Troubleshooting

Why is my cake dry/crumbly?

Dryness can be a common issue with baking cakes. It’s either a result of over-mixing or over-baking! Though, keep in mind that under-mixing and under-baking can be equally as bad. So, be sure to follow the directions in the recipe card below (and make sure your oven is at the right temperature!) for the best results in this cake!

Why are there lumps of flour in my batter/cake?

If there are lumps of dry ingredients in your batter and/or cake, this is likely due to the dry ingredients not being incorporated properly. Be sure to follow the recipe below for best results!

Why is my cake tough?

Tough cake is usually caused by over-mixing, which over-develops the gluten and that leads to a tough, dry, and dense cake.

Why did my cake not rise?

If your cake didn’t rise, this could be a few things. The most common is that the cake was over-mixed. It could also be that your baking powder is out of date! So, be sure to always check the expiration dates on your ingredients before baking.

Why is my frosting lumpy?

Well, this is usually caused the powdered sugar or cocoa powder wasn’t sifted and had lumps in it. A few minutes on high in the mixer should fix this problem!

Can this recipe be made into cupcakes?

Definitely! All you need to do is line a muffin pan with cupcake papers and fill each paper about ¾ full. Bake for 20 minutes, or until the cupcakes test done!
