Step-by-Step Instructions
Preparation Steps
1. First, preheat your oven to 350°F (175°C).
2. Prepare two 9-inch round cake pans. Grease them with butter or non-stick spray. You can also line them with parchment paper.
3. In a medium bowl, whisk together:
- 1 ¾ cups all-purpose flour
- 1 ½ teaspoons baking powder
- 1 teaspoon baking soda
- ½ teaspoon salt
- ¾ cup unsweetened cocoa powder
4. Set this dry mix aside for later.
Baking Instructions
5. In a large bowl, mix:
- 1 cup granulated sugar
- ½ cup packed brown sugar
- 2 large eggs
6. Use an electric mixer to beat this mix on medium speed until light and fluffy, about 3-4 minutes.
7. Next, add:
- 1 cup whole milk
- ½ cup vegetable oil
8. Mix until well combined. Then, add:
- 2 teaspoons vanilla extract
9. Blend this until well mixed.
10. Gradually add the dry flour mix to the wet mix. Mix on low speed until the batter comes together. Don’t overmix!
11. Slowly stir in 1 cup boiling water. The batter will be thin, but that’s fine!
12. Divide the batter evenly between the two prepared pans.
13. Bake for 30-35 minutes. To check if it’s done, insert a toothpick. It should come out clean with a few moist crumbs.
Ganache Preparation
14. While the cakes cool, prepare the ganache. In a small saucepan, heat:
- 1 cup heavy cream
15. Heat until it simmers gently, then remove from heat.
16. Add:
- 8 ounces dark chocolate (70% cocoa), finely chopped
- 2 tablespoons unsalted butter
17. Let it sit for 2-3 minutes. Then whisk until smooth and glossy.
18. Once the cake layers cool, place one layer on a serving plate. Pour ganache over the top, letting it drip down the sides.
19. Place the second layer on top. Repeat the ganache pour over this layer, covering the whole cake.
20. Chill the cake in the fridge for about 30 minutes to let the ganache set.
21. Just before serving, sprinkle flaky sea salt on top for a tasty contrast.
Tips & Tricks
How to Achieve the Perfect Ganache
To get a smooth ganache, use high-quality dark chocolate. Chop it finely for faster melting. Heat the heavy cream until it simmers, but don't boil it. Remove it from heat, then add the chocolate and butter. Let it sit for a few minutes. This helps the chocolate melt evenly. Finally, whisk until you see a glossy finish.
Cake Texture Improvements
For a moist cake, add boiling water to the batter. This step makes the cake soft and rich. Be careful not to overmix the batter when adding the dry ingredients. Overmixing can lead to a tough cake. Using room-temperature ingredients helps them blend better. Also, let the cake cool completely before adding the ganache.
Common Mistakes to Avoid
One mistake is not measuring ingredients accurately. Always use measuring cups and spoons for best results. Another is not greasing the pans well. This can cause the cake to stick. Avoid opening the oven door too early. This can cause the cake to sink. Lastly, don’t skip the chilling step after applying ganache. It sets the chocolate nicely, making it look great.
Pro Tips
- Use Quality Chocolate: The flavor of your ganache is heavily influenced by the quality of chocolate you use. Opt for high-quality dark chocolate with at least 70% cocoa for a rich, decadent flavor.
- Cool Cakes Completely: Ensure your cake layers are completely cooled before adding ganache to prevent it from melting and sliding off. This helps achieve a beautiful finish.
- Perfect Ganache Consistency: If your ganache is too thick, gently reheat it in a microwave or over a double boiler until it reaches a pourable consistency. This will help it glide over the cake smoothly.
- Flaky Sea Salt Finish: Adding flaky sea salt on top of your finished cake enhances the chocolate flavor and adds a delightful crunch. Just a small pinch will do!
Variations
Flavor Tweaks
You can add different flavors to your ganache cake. A splash of espresso gives the cake a coffee kick. Just mix in 1 to 2 teaspoons of espresso powder when you add the cocoa. If you like spices, try adding cinnamon or a pinch of cayenne. These warm notes can enhance the chocolate flavor.
Dietary Modifications
You can make this cake gluten-free. Use a gluten-free flour blend instead of all-purpose flour. For a vegan version, swap eggs with flax eggs. Mix 1 tablespoon of ground flaxseed with 3 tablespoons of water for one egg. Use almond or oat milk instead of whole milk.
Serving Suggestions
Pair the cake with fresh fruit, like raspberries or strawberries. Their tartness balances the rich chocolate. For a fun twist, serve with vanilla ice cream. You can also top the cake with whipped cream or chocolate shavings. A sprinkle of flaky sea salt adds a nice touch too!
Storage Info
Best Way to Store Leftover Cake
To store leftover cake, wrap it tightly in plastic wrap. This keeps it moist and fresh. You can also use an airtight container for better protection. Make sure to keep it at room temperature for short-term storage. For longer storage, the fridge is best.
Freezing Instructions
If you need to freeze the cake, slice it first. Wrap each slice in plastic wrap, then in foil. This helps prevent freezer burn. Place the wrapped slices in a freezer-safe bag. You can freeze the cake for up to three months. When ready to eat, thaw it in the fridge overnight.
How Long the Cake Lasts
The cake lasts about 3-4 days at room temperature. In the fridge, it can last up to a week. Always check for signs of spoilage before enjoying. If it looks or smells off, it’s best to toss it. Stay safe and enjoy your delicious ganache cake!
FAQs
How to Make Velvety Dark Chocolate Ganache?

Remove it from the heat and add the chopped chocolate and butter. Let it sit for a few minutes. Then whisk until smooth and glossy. This ganache will coat your cake perfectly.
What Makes a Cake Velvety?
A velvety cake has a few key traits. First, the right balance of fat and moisture is essential. Using oil instead of butter adds tenderness. Also, adding boiling water to the batter keeps it moist. Mixing the ingredients just until combined helps maintain a light texture. These steps create a cake that melts in your mouth.
Can I use milk chocolate instead of dark chocolate?
Yes, you can use milk chocolate instead of dark chocolate. However, the flavor will change. Milk chocolate is sweeter and creamier. This will make your ganache less rich.
