How to Make Black Cocoa Loaf Cake

PIN IT

Step 1: Preheat and Prep

Preheat your oven to 350°F (175°C). Grease and line a loaf pan with parchment paper — this makes lifting the cake out a breeze.

Step 2: Combine Dry Ingredients

In a large bowl, whisk together flour, black cocoa powder, baking powder, baking soda, and salt. The cocoa will be intensely dark — that’s exactly what we want!

Step 3: Mix Wet Ingredients

In another bowl, whisk sugar, oil, eggs, buttermilk, and vanilla until smooth and glossy.

Step 4: Combine and Stir

Add the dry ingredients into the wet mixture in two additions, gently folding until no dry streaks remain. Don’t overmix — we want a tender crumb.

Step 5: Bake

Pour the batter into the prepared pan and smooth the top. Bake for 45–55 minutes or until a toothpick inserted in the center comes out mostly clean.

Step 6: Cool and Glaze (Optional)

Let the cake cool in the pan for 10 minutes, then transfer to a wire rack. If you’d like, melt chocolate chips with cream to create a silky ganache and drizzle over the cooled cake.

What to Serve with Black Cocoa Loaf Cake

Serve warm slices with vanilla ice cream, a dollop of whipped cream, or a cold glass of milk. For brunch, pair it with your morning latte or a cozy chai.

You can also enjoy it alongside other chocolatey favorites like Chocolate Chip Banana Bread, Mocha Espresso Cupcakes, or Oreo Cheesecake Bars.

Tips for Making It Perfect

• Use quality cocoa: The flavor truly depends on it — black cocoa brings intensity, but Dutch-processed works too.
• Measure correctly: Spoon and level your flour for best texture.
• Don’t overbake: Slightly underbaked is better than dry!
• Store airtight: Keeps the crumb soft for days.

Storage Instructions

Store at room temperature for up to 4 days or refrigerate for up to a week. To freeze, wrap slices individually in plastic and foil — they’ll last 2–3 months. Thaw at room temperature or warm slightly before serving.

General Information

Black cocoa is a special type of cocoa powder that’s been heavily Dutch-processed, giving it that inky black color and smooth flavor (like Oreo cookies). It’s less acidic and pairs beautifully with buttermilk-based batters. Perfect for dramatic desserts!

Frequently Asked Questions

Can I use regular cocoa powder instead?
Yes! It will still taste amazing, just lighter in color and slightly tangier in flavor.

Why did my loaf sink in the middle?
Usually from overmixing or underbaking — check with a toothpick and use room-temp ingredients.

Is this cake sweet?
It’s balanced — not overly sweet. The black cocoa has a pleasant bitterness that pairs well with a glaze.

Can I double this recipe?
Yes, double the ingredients and bake in two pans or a 9×13-inch pan.

Can I make it vegan?
Absolutely — replace eggs with flax eggs and use plant-based milk with vinegar instead of buttermilk.
