Rich Chocolate Bundt Cake with Glossy Ganache

This chocolate bundt cake is the one I make when I want a dessert that looks like I planned it but comes together with a bowl and a whisk. It bakes up tall and tender, with a deep cocoa flavor that feels right at home on a Tuesday or a holiday table.

A glossy ganache poured over the top takes less than five minutes and makes the whole thing look polished, no piping bags required.

What Keeps This Cake So Moist

A mix of buttermilk and neutral oil gives the crumb a soft, almost velvety texture that stays that way for days. There is no creaming butter, no waiting for ingredients to come to room temperature, just a straight shot from bowl to oven.

The ganache seals the surface as it sets, so every slice holds its moisture until the last bite. This is the chocolate cake I keep coming back to when I need one that never fails.

Ingredients

• 2 cups (250 g) all-purpose flour: spooned and leveled, not scooped
• 1 ¾ cups (350 g) granulated sugar
• ¾ cup (65 g) unsweetened natural cocoa powder: not Dutch process for this recipe
• 2 tsp baking powder
• 1 tsp baking soda
• 1 tsp kosher salt
• 1 cup (240 ml) buttermilk: cold from the fridge is fine
• ½ cup (120 ml) neutral oil: avocado or vegetable oil
• 2 large eggs
• 2 tsp vanilla extract
• ¾ cup (180 ml) hot coffee: brings out the chocolate flavor without tasting like coffee

For the ganache

• 4 oz (115 g) semisweet chocolate: chopped or high-quality chips
• ½ cup (120 ml) heavy cream

Variations / Substitutions

• Swap Dutch process cocoa: use it if you have it, but the cake may rise a little less. The flavor will be milder and the color darker.
• Make it dairy-free: replace the buttermilk with a scant cup of oat milk mixed with 1 tablespoon vinegar, and use coconut cream for the ganache. The ganache won’t be as glossy but it will still set.
• Skip the coffee: use hot water instead. The chocolate will still be rich but without the subtle depth the coffee adds.
• Try a different glaze: a dusting of powdered sugar or a simple vanilla glaze works when you want something lighter.

How to Make Rich Chocolate Bundt Cake

Step 1: Whisk the Dry Ingredients

Set a rack in the lower third of the oven and preheat to 350°F (175°C). Grease a standard 10 to 12 cup bundt pan thoroughly with softened butter or a baking spray that contains flour.

In a large bowl, whisk together the 2 cups flour, 1 ¾ cups sugar, ¾ cup cocoa powder, 2 teaspoons baking powder, 1 teaspoon baking soda, and 1 teaspoon salt until the cocoa is evenly distributed and there are no lumps.

The mixture will look pale brown and fluffy, with a slight sheen from the cocoa. A quick press with the back of a spoon should not reveal any dark cocoa pockets.

Step 2: Stir the Wet Ingredients Into the Dry

Pour the 1 cup buttermilk, ½ cup oil, 2 eggs, and 2 teaspoons vanilla directly into the bowl of dry ingredients. Start stirring with a whisk or a sturdy spatula, and as the batter begins to come together, pour in the ¾ cup hot coffee.

Beat for about 1 minute, just until the batter is smooth and glossy. It will be thin, almost like pancake batter, and that is exactly what you want.

Step 3: Pour and Bake the Cake

Pour the batter into the prepared bundt pan, scraping the bowl with a spatula. Gently tap the pan on the counter twice to release any large air bubbles.

Bake for 45 to 55 minutes, until a toothpick inserted in the thickest part comes out with a few moist crumbs. The top will be domed and a deep, matte brown.

If your pan is very dark, start checking at 40 minutes. The cake will pull away from the sides just slightly when it is done.

Step 4: Drizzle the Ganache

Let the cake cool in the pan on a wire rack for 10 minutes. Loosen the edges with a thin knife, then invert it onto the rack and lift the pan off. Cool completely before glazing, about an hour.

While the cake cools, make the ganache. Place the 4 ounces of chopped chocolate in a heatproof bowl. Warm the ½ cup cream in a small saucepan until it just starts to steam, then pour it over the chocolate and let it sit for 2 minutes. Stir slowly until the mixture is smooth and glossy.

Spoon the ganache over the top of the cooled cake, letting it drip down the sides. Let it set for about 15 minutes before slicing.

Tips for a Clean Release

• Grease every nook of your bundt pan with butter or a flour-based baking spray. Pay extra attention to the center tube and any intricate ridges, because cocoa batter clings more than vanilla.
• If you do not have buttermilk, stir 1 tablespoon of white vinegar or lemon juice into 1 cup of milk and let it sit 5 minutes. Use it the same way.
• The coffee trick sounds odd, but you will not taste it. Hot liquid helps bloom the cocoa powder, deepening the chocolate flavor without adding a drop of coffee taste.

Bake times by pan material:

Storing Leftovers

• Refrigerate: Wrap the cake or place it under a cake dome and refrigerate for up to 5 days. The ganache will firm up but stay fudgy.
• Serve cold: This cake is excellent straight from the fridge, with an almost truffle-like density.
• Freeze: Wrap unglazed slices tightly and freeze for up to 3 months. Thaw at room temperature and make a fresh batch of ganache to pour over the top.

What To Serve With Rich Chocolate Bundt Cake

A scoop of vanilla ice cream is the obvious choice, and the cold creaminess cuts the intensity of the chocolate the way milk softens a brownie. For something brighter, pile fresh raspberries alongside; their tartness wakes up the cocoa. A cloud of barely sweetened whipped cream works if you want the cake to stay the star.

Frequently Asked Questions

Can I use Dutch process cocoa instead?

Yes, but the cake may not rise as high. The recipe was tested with natural cocoa, which reacts with the baking soda for lift. If you only have Dutch process, swap the baking soda for an equal amount of additional baking powder and expect a slightly denser crumb.

My cake stuck to the pan. What happened?

Even with greasing, cocoa cakes can cling. Make sure you use a brush or spray to coat every crevice, and cool the cake for exactly 10 minutes before inverting. If you wait too long, the sugar can cool into a tacky glue.

Can I make this in a different pan?

A bundt pan gives you the best center-to-edge ratio, but you can bake the batter in two 9-inch round pans. Start checking at 25 minutes. The texture will be the same, but you will lose the dramatic shape and the ganache cascade.

Ingredients

  

• 2 cups (250 g) all-purpose flour
• 1 ¾ cups (350 g) granulated sugar
• ¾ cup (65 g) unsweetened natural cocoa powder
• 2 tsp baking powder
• 1 tsp baking soda
• 1 tsp kosher salt
• 1 cup (240 ml) buttermilk
• ½ cup (120 ml) neutral oil
• 2 large eggs
• 2 tsp vanilla extract
• ¾ cup (180 ml) hot coffee
• 4 oz (115 g) semisweet chocolate, chopped
• ½ cup (120 ml) heavy cream

Method

 

1. Preheat the oven to 350°F (175°C). Grease a 10 to 12 cup bundt pan. Whisk flour, sugar, cocoa, baking powder, baking soda, and salt in a large bowl until smooth.
2. Add buttermilk, oil, eggs, and vanilla to the dry ingredients and begin stirring. Pour in the hot coffee and beat for about 1 minute until the batter is thin and glossy.
3. Pour the batter into the prepared pan and tap it gently on the counter. Bake for 45 to 55 minutes, until a toothpick inserted in the center comes out with moist crumbs. Cool in the pan for 10 minutes, then invert onto a rack to cool completely.
4. Place chopped chocolate in a heatproof bowl. Warm the cream until steaming, pour it over the chocolate, let stand 2 minutes, then stir until smooth. Spoon the ganache over the cooled cake, letting it drip down the sides. Let set 15 minutes before slicing.

Notes

The cake needs to cool fully before you add the ganache, so plan on an hour of cooling time after it leaves the oven. The ganache can be made while the cake cools, and any extra is wonderful warmed and poured over ice cream.
