Halloween Special: Black Velvet Guinness Cake Recipe
About This Black Velvet Guinness Cake
What It Is: A rich, moist chocolate cake made with Guinness stout, regular cocoa powder, black cocoa powder, brown sugar, and sour cream, finished with a smooth, tangy cream cheese frosting.
Cuisine: Modern American-style chocolate cake inspired by velvet cakes and stout-based chocolate cakes. This is a contemporary variation rather than a traditional historical black velvet cake.
Servings: One 8-inch round cake, approximately 8–10 slices.
Cooking Method: Melting butter with stout, incorporating cocoa and sugar, folding in the dry ingredients, oven-baking, and finishing with a whipped cream cheese frosting.
Estimated Time: Approximately 25–30 minutes of preparation, 50–60 minutes of baking, plus complete cooling and frosting time. Allow around 3 hours overall, depending on how quickly the cake cools.
Flavor & Texture: Deep chocolate flavor with roasted, malty notes from Guinness, subtle caramel-like sweetness from brown sugar, and a soft, moist crumb. The cream cheese frosting adds a smooth, lightly tangy finish.
What Makes This Version Different: Instead of relying entirely on black cocoa, this recipe combines regular cocoa powder with a smaller amount of black cocoa for a balanced chocolate flavor. Guinness stout adds roasted complexity, while sour cream helps create a tender cake. The single-layer presentation keeps the recipe approachable without sacrificing richness.
Equipment: Oven, 8-inch springform cake pan, saucepan or pot, mixing bowls, whisk or spatula, hand mixer or stand mixer, parchment paper, and a wire cooling rack.
Halloween is here, and apparently, I haven't had enough of black cocoa yet. After experimenting with my Noir Cookies, I decided to take things in a slightly different direction and make a Black Velvet Cake.
But instead of simply turning an ordinary chocolate cake black, I wanted something with a little more character. Something rich, moist, deeply chocolatey, and not overly complicated to make. That's where Guinness stout comes in. Paired with good-quality cocoa powder, brown sugar, butter, and sour cream, it creates a cake with a deep, slightly malty flavor and a wonderfully tender crumb.
Just outta the oven...
And because I already had cream cheese on hand, I figured a simple cream cheese frosting would be the perfect finishing touch. No elaborate decorations, no unnecessary fuss. Just a dark chocolate cake dressed up for Halloween.
The idea of velvet cakes goes back much further than the bright red cakes we commonly see today. Historically, the term "velvet" was used to describe cakes with an especially fine, soft texture.
Cocoa became associated with some of these cakes. In contrast, the modern red velvet cake eventually developed into its own recognizable dessert, typically featuring cocoa, acidic dairy ingredients, and cream cheese or ermine frosting.
Black velvet cake is a more recent variation rather than a single traditional recipe with a clearly established origin. Its dramatic appearance often comes from black cocoa powder, which has been heavily alkalized to produce an almost-black color.
For my version, I decided to combine regular cocoa with a smaller amount of black cocoa rather than rely entirely on the latter. I still wanted the familiar richness of a chocolate cake, with the black cocoa contributing a darker appearance and a slightly different cocoa character.
And then there's the Guinness. Stout and chocolate have long been paired in cakes because their roasted, malty flavors complement one another. Guinness brings more than just a bit of bitterness to the batter; it also contributes liquid and a distinctive roasted flavor that works beautifully with the cocoa and brown sugar.
The sour cream adds richness and helps keep the crumb tender, while the cream cheese frosting provides a tangy contrast to the sweet, chocolatey cake. I made this in an 8-inch springform pan, keeping everything relatively straightforward.
No complicated layering or fancy piping required. If the top rises and cracks a little during baking, that's perfectly fine. Cover it with frosting and call it character. After all, Halloween is supposed to be a little imperfect, a little mysterious, and a whole lot of fun. Happy Halloween!

Black Cocoa, 10g
Brown Sugar, 234g
Granulated Sugar, 43g

Icing Sugar, 80g
Vanilla Paste, 1/2 TSP
Fresh Orange Zest, 1/2 Orange
Equipment:
Oven
8" Spring Form Round Cake Pan
Hand / Stand Mixer
Directions:
Preheat the oven to 160°C / 320°F.
Line the bottom of an 8-inch springform cake pan with parchment paper. Lightly grease the parchment and sides of the pan with neutral cooking oil or nonstick cooking spray.
Dust the greased sides of the pan with a little cocoa powder, rotating the pan to coat them evenly. Tap out any excess. Using cocoa instead of flour helps avoid leaving pale marks on the finished dark cake.
In a mixing bowl, combine the all-purpose flour, baking powder, and sea salt. Stir thoroughly to distribute the ingredients evenly, then set aside.
Add the Guinness stout and unsalted butter to a large saucepan or pot over medium-low heat.
Stir occasionally until the butter has completely melted. There's no need to bring the mixture to a vigorous boil.
Turn off the heat and add the regular cocoa powder and black cocoa powder.
Whisk until the cocoa powders are thoroughly incorporated and no large lumps remain.
Add the brown sugar and granulated sugar. Stir until evenly combined.
Allow the mixture to cool until warm rather than hot before proceeding. This is important because adding eggs directly to a very hot mixture could cause them to cook prematurely.
Add the sour cream or crème fraîche and whisk until incorporated.
Add the whole egg, egg yolk, and vanilla paste. Whisk until the mixture looks smooth and evenly combined.
Add the prepared dry ingredients to the wet mixture.
Using a spatula, gently fold until no visible pockets of dry flour remain. Scrape the bottom and sides of the pot or bowl to make sure everything is incorporated.
Avoid overmixing. Excessive mixing after adding the flour can develop too much gluten, resulting in a tougher cake. A few tiny lumps are fine.
Transfer the batter to the prepared springform cake pan. Gently level the surface with a spatula if necessary.
Place the cake pan on the middle rack of the preheated oven and bake for approximately 50–55 minutes.
Begin checking for doneness toward the end of the baking window. Insert a wooden skewer into the center of the cake. It should come out clean or with a few moist crumbs attached, but not with wet batter.
The center of the cake should be set, and the top may rise and develop a few cracks. That's perfectly normal for this style of cake.
Remove the cake from the oven and place the pan on a wire cooling rack.
Allow the cake to cool in the pan until it is stable enough to handle. Then carefully release the springform ring and let the cake cool completely before frosting. Do not frost a warm cake, or the cream cheese frosting may soften and slide off.
While the cake is cooling, prepare the frosting. Add the softened cream cheese and unsalted butter to a large mixing bowl.
Using a hand mixer or stand mixer, beat until smooth and creamy, scraping down the sides of the bowl as necessary.
Add the sifted powdered sugar, vanilla paste, and orange zest
Continue mixing on low speed until the sugar is incorporated, then beat briefly until the frosting is smooth and spreadable. Avoid excessive whipping, which can make some cream cheese frostings loose.
Once the cake has cooled completely, carefully transfer it to a serving plate or cake stand.
Spread the cream cheese frosting generously over the top of the cake using an offset spatula or the back of a spoon. You can create soft swirls for a rustic finish.
Slice and serve immediately, or refrigerate the frosted cake until ready to serve. For a softer texture, allow a chilled slice to sit briefly at room temperature before eating.
Tips:
Use good-quality cocoa powder.
Cocoa is one of the main flavors in this cake, so the quality of your cocoa powder matters. I prefer using Callebaut or Valrhona when available.
Don't confuse black cocoa with regular cocoa.
Black cocoa is heavily alkalized and has a different flavor and appearance from natural cocoa powder. This recipe combines the two intentionally, so I wouldn't recommend replacing one with the other without testing.
Don't boil the stout and butter aggressively.
You only need enough heat to melt the butter. Excessive boiling can reduce the liquid and change the balance of the batter.
Let the chocolate mixture cool before adding the eggs.
If the mixture is too hot, the eggs can begin to cook before they're properly incorporated.
Use room-temperature sour cream or crème fraîche.
This helps the dairy incorporate more smoothly into the batter.
Don't overmix the batter.
Once the flour is added, fold gently until no dry pockets remain. Overmixing can make the cake tougher.
Don't worry about cracks on top.
A few cracks are perfectly normal. The cream cheese frosting will cover them anyway.
Check for moist crumbs, not a completely dry skewer.
A few moist crumbs are fine. Wet batter means the cake needs more time, but baking until the skewer is bone-dry can lead to an overbaked cake.
Cool the cake completely before frosting.
Cream cheese frosting softens when exposed to heat. Frosting a warm cake can turn it into a sliding mess.
Use fresh cream cheese if available.
It generally produces a firmer frosting than soft cream cheese spread sold in tubs.
Sift the powdered sugar.
This helps prevent lumps and creates a smoother frosting.
Keep the frosting simple.
You don't need elaborate piping for this cake. A generous layer of frosting with a few rustic swirls works beautifully.
Remember that Guinness contains alcohol.
Some alcohol evaporates during baking, but not necessarily all of it. This recipe isn't suitable for anyone who needs to avoid alcohol completely.
FAQ:
What is Black Velvet Cake?
Black velvet cake is a modern variation of velvet-style cake, usually made with dark cocoa ingredients to produce a deep-colored crumb. Unlike classic red velvet cake, it emphasizes a darker chocolate appearance and flavor.
Is Black Velvet Cake the same as chocolate cake?
They're closely related. Black velvet cake is generally a type of chocolate cake, but recipes often emphasize a fine, tender crumb and use black cocoa or other dark ingredients for a more dramatic appearance.
What does Guinness do in chocolate cake?
Guinness contributes roasted, malty notes that complement cocoa and brown sugar. It also adds liquid to the batter. The finished cake doesn't necessarily taste strongly of beer, but the stout influences its overall flavor.
Does the alcohol cook off completely?
No. Baking reduces the alcohol content, but it doesn't guarantee complete removal. Anyone who must avoid alcohol should choose a tested alcohol-free recipe.
Can I use another stout instead of Guinness?
Yes, although different stouts vary in sweetness, bitterness, roastiness, and alcohol content. Those differences can affect the finished cake.
Can I use natural cocoa powder instead of black cocoa?
You can experiment, but the cake won't have the same appearance or flavor. Black cocoa is heavily alkalized, and replacing it with natural cocoa can affect the batter's chemistry, particularly when different leavening agents are used.
Why does this cake contain sour cream?
Sour cream contributes fat, moisture, and acidity, helping create a rich, tender crumb. Crème fraîche can also be used, although its flavor and acidity may differ.
Can I replace sour cream with crème fraîche?
Yes. Both work in this recipe, but crème fraîche is generally less tangy than sour cream, so the finished flavor may be slightly different.
Why did my cake crack on top?
Cracking can occur as the cake rises and the surface sets during baking. A few cracks are normal and don't mean the cake has failed.
How do I know when the cake is baked?
Insert a wooden skewer into the center. It should come out clean or with a few moist crumbs, without wet batter. The center should also appear set.
Can I make this cake without a springform pan?
An 8-inch round cake pan of sufficient depth may work, but lining and unmolding will require extra care. Make sure the pan can safely accommodate the batter without overflowing.
Can I use mascarpone instead of cream cheese?
Yes, but the frosting will taste different. Mascarpone is richer and milder, while cream cheese provides a more pronounced tanginess. Mascarpone can also become loose if overmixed.
Why is my cream cheese frosting runny?
Possible causes include cream cheese that is too warm, using a soft spread instead of firmer block cream cheese, excessive mixing, or frosting a cake that hasn't cooled completely.
Can I make the cake ahead of time?
Yes. You can bake the cake a day ahead, allow it to cool completely, and store it properly covered. Prepare the frosting and assemble when convenient.
How should I store the finished cake?
Because the frosting contains cream cheese, refrigerate the finished cake in a covered container. For best quality, enjoy it within approximately 3–4 days. Don't leave it sitting at room temperature for extended periods, especially in Singapore's warm climate.
Can I freeze Black Velvet Cake?
The unfrosted cake can be wrapped tightly and frozen. Thaw it while wrapped, then frost once completely thawed. Freezing the assembled cake is possible, but the frosting's texture may change slightly after thawing.
