Ingredients You’ll Need

The magic of this Black Velvet Cake with Dark Chocolate Buttercream Recipe comes from a balance of dark, rich ingredients and simple pantry staples that work beautifully together. I always recommend grabbing good-quality black cocoa powder and dark chocolate chips—they really elevate the flavor and make a difference in the finished cake.

• All-purpose flour: Using the right amount measured by weight ensures perfect crumb every time.
• Granulated sugar: Sweetens and adds tenderness to the cake layers.
• Black cocoa powder: The star ingredient that gives the cake its intense color and chocolatiness.
• Baking powder & baking soda: These leaveners keep the cake light and fluffy.
• Salt: Balances sweetness and enhances flavors.
• Hot water: Helps bloom the cocoa for more robust chocolate flavor.
• Instant espresso or coffee: A secret ingredient to intensify the chocolate without making the cake taste like coffee.
• Buttermilk: Adds moisture and tenderizes the crumb.
• Vegetable or canola oil: Keeps the cake moist and soft.
• Large eggs: Provide structure and richness.
• Vanilla extract or vanilla bean paste: Enhances overall flavor depth.
• Unsalted butter: Essential for the smooth, creamy dark chocolate buttercream.
• Powdered sugar: Sweetens and sweetens the frosting with a silky finish.
• Heavy whipping cream: Lightens the frosting for the perfect spreadable texture.
• Dark chocolate chips: Melted and cooled for that rich chocolate swirl in the buttercream.

Variations

I love how versatile this Black Velvet Cake with Dark Chocolate Buttercream Recipe is. Over the years, I’ve played around with a few tweaks to match different occasions or dietary needs, and honestly, it’s pretty forgiving. Feel free to get creative—it’s all about making it your own!

• Gluten-free version: I’ve swapped the all-purpose flour for a blend of gluten-free flours and added a bit of xanthan gum—it turned out surprisingly tender and delicious!
• Mocha twist: Adding an extra teaspoon of instant espresso powder to the batter amps up the coffee flavor if you’re a mocha fan like me.
• Vegan adaptation: I once tried replacing eggs with flax eggs and using coconut oil instead of butter and oil—while not quite the same richness, it was a nice plant-based alternative.
• Decorative finishes: You can drizzle ganache over the frosted cake or sprinkle crushed chocolate-covered espresso beans for an extra crunch.

How to Make Black Velvet Cake with Dark Chocolate Buttercream Recipe

Step 1: Prepare and Mix Your Dry Ingredients

Start by preheating your oven to 350°F (175°C) and prepping your pans—grease and line three 8-inch cake pans or four 7-inch ones, whichever you have. Then whisk together your flour, sugar, black cocoa powder, baking powder, baking soda, and salt in a large bowl until no lumps remain. I’ve found this step essential because evenly mixed dry ingredients help your cake rise beautifully without uneven spots.

Step 2: Brew the Chocolate Base with Hot Water and Espresso

In a separate bowl, stir the hot water and instant espresso or coffee until dissolved. This petite bit of espresso is my secret weapon—it doesn’t make your cake taste like coffee but lifts the chocolate flavor to a new level of richness. Once the coffee is dissolved, add your buttermilk, oil, eggs, and vanilla extract, mixing just until smooth.

Step 3: Combine Wet and Dry Ingredients

Pour the wet ingredients into the dry ingredients and gently mix by hand until fully combined. The batter will be thinner than you might expect—that’s exactly how it should be. Resist the urge to overmix here; just stir until everything comes together to keep your cake tender and moist.

Step 4: Bake the Cake Layers

Divide the batter evenly among your prepared pans — here’s a trick I swear by: I use a kitchen scale to weigh the batter in each pan to get them perfectly even. This ensures your layers bake evenly and stack up nice and straight. Pop them in the oven for 24 to 27 minutes or until a toothpick inserted in the center comes out clean. After baking, let the cakes cool in the pans for about 10 minutes, then loosen their edges with a spatula and flip out onto wire racks to cool completely.

Step 5: Whip Up the Dark Chocolate Buttercream

Start by beating your room-temperature butter for about 30 seconds on medium speed until creamy. Then add black cocoa powder, vanilla extract, and salt, mixing slowly to combine. Gradually add powdered sugar, and halfway through, pour in the heavy cream to keep the frosting silky and easy to spread. Finally, fold in the melted, cooled dark chocolate. I wait about 10 minutes after melting the chocolate so it’s fluid, but not hot — this prevents your buttercream from breaking or melting. Scrape the bowl sides as you mix to get a smooth, rich frosting ready to take your cake to the next level.

Step 6: Assemble and Frost Your Black Velvet Cake

Place your first cooled cake layer on a greaseproof cake board and spread a generous layer of buttercream on top using a large offset spatula. Stack each layer carefully, adding frosting in between. Once stacked, apply a thin coat of frosting all around the cake to lock in crumbs, then chill the cake for about 30 minutes to set the crumb coat—this step is my best tip for getting that smooth, professional finish. After chilling, add a thicker second layer of frosting, smooth with a bench scraper, and decorate as you please. I love using a piping bag with an open star tip to add elegant swirls or rosettes on top!

How to Serve Black Velvet Cake with Dark Chocolate Buttercream Recipe

Garnishes

I honestly keep it simple to let the rich flavors shine, but my go-to garnishes are a few chocolate shavings or curls on top, maybe a sprinkle of cocoa powder, or even some fresh raspberries if I want a little tart contrast. These little touches add elegance without overshadowing the deep dark chocolate flavor.

Side Dishes

This cake pairs beautifully with a scoop of vanilla bean ice cream or a small dollop of lightly sweetened whipped cream. If you’re serving it at a party, I like to offer some fresh berries or a fruity coulis on the side—it cuts through the richness and balances the dessert perfectly.

Creative Ways to Present

For birthdays or special occasions, I’ve tried stacking mini versions of this cake on a tiered stand for a dramatic effect. Another fun idea? Use edible gold leaf or chocolate transfer sheets on some sides of the cake for a luxurious look. Trust me, the presentation will wow your guests before they take their first bite!

Make Ahead and Storage

Storing Leftovers

My best advice? Wrap leftovers tightly and store your frosted cake in the refrigerator. It keeps wonderfully for up to a week thanks to the buttercream’s moisture-locking magic. If you’re worried about the frosting drying out, I sometimes cover the cake loosely with a dome or foil to protect it.

Freezing

I usually freeze individual cake layers right after I bake and level them, wrapped tightly in plastic wrap and foil. When you’re ready, just thaw in the fridge overnight before frosting. You can also freeze a fully frosted cake for up to a month—just wrap it well to prevent freezer burn. It’s a lifesaver when prepping for big events!

Reheating

If you want to warm a slice, do it briefly in the microwave—about 10 to 15 seconds at medium power. This softens the buttercream and brings out those luscious chocolate flavors without drying the cake. Just watch carefully so it doesn’t melt through!
