Bakery-Style Chocolate Cake Recipe with Hot Coffee and Ganache
This reliable chocolate cake recipe delivers a moist, dark crumb using Dutch cocoa, sour cream, and hot coffee. Topped with a glossy ganache, it is the best chocolate cake for any occasion.
If you have been searching for the ultimate chocolate cake recipe, look no further than this one-bowl wonder. The secret to a truly moist chocolate cake lies in the chemistry of acidic sour cream and the blooming of Dutch-processed cocoa powder with boiling hot coffee.
While many recipes rely on butter for flavor, we use oil here to ensure the crumb stays tender even when refrigerated. It is, quite simply, the best chocolate cake for anyone who values a deep, dark cocoa profile over cloying sweetness.
The finishing touch is a simple two-ingredient glossy ganache. It provides a sophisticated, professional look without the hassle of whipping temperamental buttercream, making this the most rewarding chocolate cake recipe in your repertoire.
Ingredients
The Cake Batter
- 2 cups (250g) all-purpose flour
- 2 cups (400g) granulated sugar
- 3/4 cup (75g) Dutch-processed cocoa powder
- 2 teaspoons baking soda
- 1 teaspoon baking powder
- 1 teaspoon kosher salt
- 1 cup (240ml) full-fat sour cream, room temperature
- 1/2 cup (120ml) neutral oil (canola or vegetable)
- 2 large eggs, room temperature
- 2 teaspoons vanilla extract
- 1 cup (240ml) strong hot coffee, freshly brewed
Glossy Ganache Frosting
- 8 ounces (225g) high-quality semi-sweet chocolate, finely chopped
- 1 cup (240ml) heavy cream
Instructions
- 1
Preheat your oven to 350°F (175°C) and grease two 8-inch round cake pans, lining the bottoms with parchment paper.
- 2
Whisk the flour, sugar, cocoa powder, baking soda, baking powder, and salt in a large bowl until no large lumps remain.
- 3
Add the sour cream, oil, eggs, and vanilla to the dry ingredients, mixing with a sturdy whisk or electric mixer on medium speed until well combined.
- 4
Pour in the hot coffee slowly while whisking by hand; the batter will be very thin and liquid, which is exactly what you want for a moist crumb.
- 5
Divide the batter evenly between the prepared pans and bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
- 6
Cool the cakes in the pans for 15 minutes before inverting them onto a wire rack to cool completely.
- 7
Prepare the ganache by placing the chopped chocolate in a heat-proof bowl and heating the heavy cream in a small saucepan until it just begins to simmer.
- 8
Pour the hot cream over the chocolate, let it sit undisturbed for 5 minutes, then whisk gently starting from the center until a glossy, smooth sauce forms.
- 9
Let the ganache sit at room temperature for about 30–60 minutes until it thickens to a spreadable consistency, then frost the cooled cake layers.
Tips
- → Do not skip the coffee; the heat blooms the cocoa powder, intensifying the chocolate flavor without making the cake taste like espresso.
- → Ensure your sour cream and eggs are at room temperature to prevent the batter from curdling or becoming gummy.
- → For the cleanest slices, use a sharp knife dipped in hot water and wiped dry between every single cut.
FAQ
Can I use natural cocoa powder instead of Dutch-process?
Dutch-process cocoa is darker and less acidic; if you swap for natural cocoa, the cake will be lighter in color and may react differently with the leavening agents. Stick to Dutch-process for that signature dark look.
How do I store this chocolate cake to keep it moist?
Store the cake in an airtight container at room temperature for up to 3 days. Because of the oil and sour cream, it stays moist longer than butter-based cakes.
Why does my chocolate cake sink in the middle?
This usually happens if the oven door is opened too early or if the leavening agents (baking soda/powder) are expired. Ensure your oven is fully preheated before sliding the pans in.
