I’ve spent years perfecting this chocolate cake recipe, and I can confidently say it produces one of the most decadent, moist chocolate cakes you’ll ever taste. The combination of coffee and Dutch-processed cocoa creates an intensely rich chocolate flavor, while the sour cream adds incredible moisture and tenderness.
The Science Behind Perfect Chocolate Cake
What makes this cake exceptionally moist and fudgy is the careful balance of ingredients. The hot coffee not only enhances the chocolate flavor by activating the cocoa powder’s compounds but also creates a thinner batter that allows for even baking. The sour cream’s acidity tenderizes the gluten, resulting in a velvet-like crumb structure.
Ingredients
For the Cake:
- 240g (2 cups) all-purpose flour
- 400g (2 cups) granulated sugar
- 75g (¾ cup) cocoa powder (Dutch-processed preferred)
- 10g (2 teaspoons) baking powder
- 7g (1½ teaspoons) baking soda
- 6g (1 teaspoon) fine sea salt
- 180ml (¾ cup) whole milk
- 120ml (½ cup) vegetable oil
- 60g (¼ cup) full-fat sour cream
- 2 large eggs, room temperature and lightly beaten
- 10ml (2 teaspoons) vanilla extract
- 240ml (1 cup) hot coffee, freshly brewed
Detailed Instructions
Preparation Phase
- Position your oven rack in the center and preheat to 175°C (350°F).
- Line a 23x33cm (9×13-inch) metal baking pan with parchment paper, ensuring some overhang for easy removal.
- Bring eggs and sour cream to room temperature for optimal incorporation.
Making the Batter
- In a large mixing bowl, whisk together the dry ingredients:
- Flour
- Sugar
- Cocoa powder
- Baking powder
- Baking soda
- Salt
- Create a well in the center of the dry ingredients and add:
- Milk
- Vegetable oil
- Sour cream
- Beaten eggs
- Vanilla extract
- Stir until well combined. The batter will resemble thick brownie batter at this stage.
- Brew your coffee and while it’s still hot, carefully add it to the batter.
- Whisk slowly at first to prevent splashing
- Continue whisking until the batter is smooth and well blended
- The batter will become quite thin – this is exactly what you want
Baking Process
- Pour the batter into your prepared pan carefully.
- Tap the pan gently on the counter 2-3 times to release any air bubbles.
- Bake for 30-35 minutes, or until:
- The top springs back when lightly touched
- A cake tester comes out clean or with just a few moist crumbs
- The edges start to pull away slightly from the pan
Cooling and Storage
- Place the pan on a wire rack and cool completely before frosting.
- For layer cakes, allow to cool in the pan for 10 minutes before turning out.
Expert Tips
- Coffee Enhancement: Use freshly brewed coffee for the best flavor. The coffee doesn’t make the cake taste like coffee – it intensifies the chocolate flavor.
- Temperature Matters: Room temperature ingredients blend better and create a more uniform texture.
- Don’t Overmix: Once you add the flour, mix just until combined to avoid developing too much gluten.
- For High Altitude (above 3,000 feet):
- Reduce sugar by 2 tablespoons
- Increase flour by 2 tablespoons
- Reduce baking powder to 1½ teaspoons
