- 60 ml Vegetable oil (neutral-flavored)
- 120 g Sour cream (full-fat, room temperature)
- 1 tbsp Instant espresso powder (intensifies chocolate)
How to Make dark chocolate cake
Step 1: Preheat the Oven
- Preheat your oven to 350°F (175°C).
- Grease and line two 9-inch round cake pans with parchment paper for easy removal.
Step 2: Prepare Chocolate Mixture
- Melt the dark chocolate gently over low heat or in the microwave.
- Stir the Dutch-process cocoa powder into the hot coffee to bloom it; let both mixtures cool slightly.
Step 3: Cream Butter and Sugar
- In a large bowl, cream the softened butter with half of the brown sugar until light and fluffy—about 3 minutes.
Step 4: Whisk Eggs
- In another bowl, whisk together the eggs with the remaining brown sugar until thickened and pale in color.
Step 5: Combine Mixtures
- Add the egg mixture to the creamed butter.
- Stir in the melted chocolate along with vanilla extract until well combined.
Step 6: Mix Dry Ingredients
- In a separate bowl, mix together all-purpose flour, baking soda, baking powder, and fine sea salt.
- Alternate adding the dry mixture with buttermilk to the wet mixture until just combined.
Step 7: Add Final Ingredients
- Gently fold in sour cream and vegetable oil until fully incorporated into the batter.
Step 8: Bake the Cakes
- Divide your batter evenly between prepared pans.
- Tap each pan gently on a countertop to release any air bubbles.
- Bake in preheated oven for about 30–35 minutes or until a toothpick inserted comes out with moist crumbs.
Step 9: Cool Cakes
- Allow cakes to cool in their pans for about 10 minutes before transferring them to a wire rack.
- If desired, wrap cakes tightly in plastic wrap and rest overnight for enhanced flavor.
How to Serve dark chocolate cake
This rich and fudgy dark chocolate cake is perfect for any occasion. Whether you’re celebrating a birthday or simply indulging in a sweet treat, here are some delightful ways to serve it.
Pair with Fresh Berries

Drizzle with Ganache
- A simple ganache made from dark chocolate and cream can enhance the cake’s decadence.
Serve with Ice Cream
- Vanilla or coffee ice cream complements the deep chocolate notes wonderfully.
Add Whipped Cream
- Lightly sweetened whipped cream provides a fluffy texture that balances the dense cake.

How to Perfect dark chocolate cake
To achieve the best results when making dark chocolate cake, consider these helpful tips:
- Use high-quality chocolate: The flavor of your cake heavily relies on the quality of the dark chocolate you choose.
- Bloom cocoa properly: Mixing cocoa powder with hot coffee ensures it releases its full flavor potential.
- Room temperature ingredients: Make sure your eggs and buttermilk are at room temperature for better emulsification and texture.
- Don’t overmix: Fold in ingredients gently to maintain the cake’s airy structure; this helps create a tender crumb.
- Check for doneness: Use a toothpick to test; it should come out with moist crumbs rather than wet batter.
Best Side Dishes for dark chocolate cake
Serving side dishes alongside dark chocolate cake can elevate your dessert experience. Here are some great options:
- Fresh Fruit Salad
A mix of seasonal fruits adds brightness and balances sweetness. - Chocolate Mousse
Rich and creamy mousse complements the cake while keeping the theme consistent. - Coffee or Espresso
A cup of freshly brewed coffee enhances the flavors of the dark chocolate. - Vanilla Pudding
Creamy vanilla pudding provides a contrasting texture and flavor profile to the dense cake. - Nutty Granola
Crunchy granola offers a delightful texture contrast when served alongside slices of cake. - Coconut Whipped Cream
For a dairy-free option, coconut whipped cream adds lightness and a hint of tropical flavor.
Common Mistakes to Avoid
Baking a dark chocolate cake can be simple, but there are common pitfalls that can affect your results. Here are some mistakes to watch out for:
- Not measuring ingredients accurately: Baking is a science. Use a kitchen scale and measuring cups to ensure you have the correct amounts.
- Using cold ingredients: Cold eggs or buttermilk can lead to a dense cake. Always bring these ingredients to room temperature before mixing.
- Overmixing the batter: Mixing too much can toughen the cake. Stir just until the ingredients are combined for a tender crumb.
- Skipping the cooling step: Allowing the cake to cool in the pan helps it set properly. Skipping this can lead to crumbling when you remove it.
- Not testing for doneness: Rely on toothpick tests to check if your cake is done. If it comes out clean or with a few moist crumbs, it’s ready.
