An overhead shot captures this dramatic Black Cocoa Bundt Cake on a vintage black cast iron cake stand, showcasing its perfect fluted edges and deep obsidian-colored crumb. Soft natural light highlights the glossy chocolate ganache cascading down the cake's ridges, pooling delicately at the base. A cross-section reveals the cake's incredibly moist, tender crumb contrasting beautifully with the midnight-black exterior. Scattered cocoa nibs and a light dusting of powdered sugar create texture against the dark surface, while a copper cake server rests nearby. The composition is completed with a white ceramic plate holding a single slice, exposing the cake's remarkably black interior against the bright white plate.

Directions

<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 170°C (340°F) with a rack positioned in the center. Thoroughly grease your Bundt pan with softened butter, making sure to get into all the crevices, then dust with cocoa powder (not flour, which would show on the dark cake). Tap out any excess cocoa. This meticulous preparation ensures your cake will release perfectly after baking.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>If using espresso powder, dissolve it in the hot water and set aside to cool slightly. The espresso won't make your cake taste like coffee; rather, it enhances and deepens the chocolate flavor by activating similar flavor compounds.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>In a medium bowl, sift together the flour, black cocoa powder, baking powder, baking soda, and salt. Sifting is crucial when working with cocoa powder, as it tends to form stubborn lumps that won't dissolve during mixing. Set this dry mixture aside.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>In the bowl of your stand mixer fitted with the paddle attachment (or using an electric hand mixer), cream the butter on medium speed until smooth and creamy, about 1 minute. Add the sugar and beat on medium-high speed for 3-5 minutes until very light and fluffy. This extended creaming creates tiny air pockets that help give your cake structure and rise.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Add eggs one at a time, beating well after each addition and scraping down the sides of the bowl as needed. The mixture may look slightly curdled - that's normal. Beat in the vanilla extract until well combined.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>With the mixer on low speed, add the dry ingredients in three additions, alternating with the buttermilk in two additions (beginning and ending with dry ingredients). Mix just until combined after each addition - overmixing develops gluten, resulting in a tough cake.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Finally, carefully pour in the hot water/espresso mixture and mix on low speed until just combined. The batter will be quite thin - this is correct! The hot water blooms the cocoa powder, intensifying its flavor and creating a uniquely tender crumb.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Pour the batter into the prepared Bundt pan, filling it no more than 3/4 full. Tap the pan gently on the counter a few times to release any large air bubbles. Smooth the top with a spatula.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Bake for 45-50 minutes, or until a wooden skewer inserted into the center comes out with just a few moist crumbs (not wet batter). The cake should also be starting to pull away slightly from the sides of the pan. Avoid opening the oven door during the first 30 minutes of baking, as temperature fluctuations can cause the cake to sink.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Allow the cake to cool in the pan on a wire rack for exactly 15 minutes - not more, not less. This timing is crucial: too short and the cake will fall apart, too long and it may stick to the pan. Then invert the pan onto the cooling rack and lift it off gently. Let the cake cool completely before glazing, at least 2 hours.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>For the ganache, place the chopped chocolate in a heatproof bowl. Heat the cream in a small saucepan until it just begins to simmer around the edges (do not boil). Pour the hot cream over the chocolate and let it sit undisturbed for 2-3 minutes to melt the chocolate. Then whisk gently until completely smooth. Whisk in the butter and corn syrup (if using) until glossy.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>Allow the ganache to cool for about 10-15 minutes until it thickens slightly but remains pourable. Place your cooled cake (still on the wire rack) over a baking sheet to catch drips. Pour the ganache evenly over the top of the cake, allowing it to drip down the sides naturally. For the most professional finish, pour in stages, allowing each layer to set slightly before adding more.</li><li class="MethodStepper"><h4 class="step-title">Step 13</h4>Let the ganache set for at least 30 minutes before transferring the cake to a serving plate. This cake actually improves with time - for the best flavor and moisture, consider making it a day ahead. Store at room temperature in a cake keeper or loosely covered with foil for up to 4 days.</li></ol>

FAQs

What ingredients are used in Black Cocoa Bundt Cake?

This recipe uses unsalted butter, sugar, eggs, vanilla, flour, black cocoa powder, leavening agents, buttermilk, hot water, and optional espresso powder. The glossy ganache requires dark chocolate, heavy cream, butter and optional corn syrup for shine.

How to cook Black Cocoa Bundt Cake at home?

Learn how to cook Black Cocoa Bundt Cake by carefully preparing your Bundt pan with butter and cocoa powder, creating a batter with alternating dry and wet ingredients, incorporating hot water to bloom the cocoa, and baking at 170°C for 45-50 minutes. The key techniques include proper pan preparation, extended butter creaming, and the hot water method for intensifying chocolate flavour.

Can I substitute regular cocoa powder for black cocoa in this recipe?

Yes, you can use Dutch-processed cocoa instead of black cocoa, though your cake won't have the same dramatic black colour. For a compromise, try using half Dutch-processed and half black cocoa to maintain darkness while ensuring good rise and chocolate flavour.

Why is my chocolate bundt cake sticking to the pan?

Bundt cakes stick when the pan isn't properly greased or when cooling time is incorrect. Thoroughly butter every crevice of your pan, dust with cocoa powder (not flour), and follow the exact 15-minute cooling time before inverting. Non-stick pans with intact coating also help prevent sticking.

What makes a chocolate cake extra moist and tender?

The secret to ultra-moist chocolate cake is using buttermilk for tenderness, adding hot water to bloom the cocoa powder, incorporating proper fats (butter), and not overbaking. This recipe's hot water technique creates a uniquely tender crumb while intensifying the chocolate flavour.
