Deep cocoa flavor with a subtle chocolate bitterness, balanced by sweet, creamy vanilla buttercream

Difficulty Level

Easy to Intermediate

Use Dutch-processed cocoa if needed, but expect a lighter color

In The Test Kitchen

I wanted these black Valentine’s Day cupcakes to look bold and dramatic without tasting artificial or dry. The key was using black cocoa sparingly for color and depth while relying on buttermilk, oil, and butter for moisture. The batter looks almost ink-black before baking but bakes up soft and plush instead of dense. For the buttercream, layering deep red and violet creates a burgundy tone, with just a tiny drop of black to keep it rich rather than muddy.

Achieving a True Black Cake

I put this cake through multiple rounds of testing before sending it to my recipe tester , and one thing became clear almost immediately: “black” cocoa powder isn’t as straightforward as it sounds. Many brands marketed as black actually bake up closer to dark brown or charcoal, while others barely deepen at all in the oven. Even when the batter looks dark going in, the finished cake doesn’t always deliver that dramatic black crumb you’re aiming for.

In one test, my recipe tester used a cocoa powder that simply refused to turn black after baking. No matter what we did, the color stalled short of true black. The takeaway was obvious: when it comes to black cake, the cocoa powder brand makes a huge difference. After comparing results, The Cocoa Trader and Modern Mountain stood out for producing a naturally deep black cake with no food coloring required. Both baked up evenly, delivered a bold bakery-style color, and continued to deepen slightly as the cake cooled, giving the most consistent and striking results overall.

Cocoa Powder

Best Choice

Black cocoa powder for the darkest color and dramatic look

Substitutions

Dutch-processed cocoa works, but the cupcakes will be dark brown instead of black

Buttermilk

Best Choice

Full-fat buttermilk at room temperature for the most tender crumb

Substitutions

Whole milk with one tablespoon vinegar per cup

Food Coloring

Best Choice

Gel food coloring for intense color without thinning the batter or frosting

Substitutions

Liquid food coloring works in a pinch but requires more and may soften the buttercream

Butter

Best Choice

Unsalted butter so you can control the salt level

Substitutions

Salted butter can be used, but skip any added salt

Erren’s Top Tips

Gel food coloring gives intense color without thinning the batter or frosting • Black cocoa adds drama without overpowering the cupcake when used in small amounts • If your buttercream looks too dark, add a tiny bit more red to brighten it back up • Chilling the cupcakes briefly before piping can help keep tall swirls crisp in warm kitchens

Variations & Add-Ins

Add a dark chocolate ganache center for an extra decadent surprise • Swap the chocolate hearts for fresh raspberries or blackberries • Flavor the buttercream with almond extract for a subtle twist • Sprinkle black sanding sugar or edible glitter over the frosting for extra drama

Storage & Freezing

Nutrition

Why aren’t my cupcakes fully black?

If you used Dutch-processed cocoa instead of black cocoa, the color will be dark brown rather than true black.

Can I make these ahead of time?

Yes. Bake the cupcakes a day ahead and frost them the day you plan to serve.

Does black cocoa taste bitter?

On its own it can be strong, but in this recipe it adds color and depth without bitterness.

Can I use natural cocoa powder?

It will work structurally, but the color will be much lighter and the flavor slightly sharper.
