This cake can be served in various forms:
- Layered Cake: Multiple cake layers with ganache between each layer.
- Drip Cake: A regular chocolate cake with ganache dripping over the edges.
- Glazed Cake: A smooth, fully coated cake with a mirror-like ganache finish.

History of Ganache
The origins of chocolate ganache trace back to 19th-century France. It is said that a pastry apprentice accidentally poured hot cream over chocolate, and his master called him a ganache—a French term meaning “fool.” However, the mistake resulted in a smooth, versatile mixture that became a staple in the world of pastry.
Over time, ganache evolved from being a simple filling to an essential element in high-end patisserie. Today, it is used in cakes, truffles, and as a glaze for various confections.
Ingredients for Chocolate Ganache Cake
For the Chocolate Cake
- 2 cups all-purpose flour
- 1 cup unsweetened cocoa powder (Dutch-processed for a deeper flavor)
- 1 ¾ cups granulated sugar
- 2 teaspoons baking soda
- 1 teaspoon baking powder
- ½ teaspoon salt
- 2 large eggs
- 1 cup buttermilk (for moisture and slight tang)
- ½ cup vegetable oil or melted butter
- 1 cup hot coffee (enhances the chocolate flavor)
- 2 teaspoons vanilla extract
For the Chocolate Ganache
- 12 ounces semi-sweet or dark chocolate, finely chopped
- 1 cup heavy cream
- 2 tablespoons unsalted butter (for extra glossiness)
- 1 teaspoon vanilla extract
Step-by-Step Instructions
Step 1: Preparing the Cake Batter
- Preheat oven to 350°F (175°C) and grease two 8-inch cake pans. Line with parchment paper for easy release.
- Mix dry ingredients: In a large bowl, sift together flour, cocoa powder, baking soda, baking powder, and salt.
- Whisk wet ingredients: In another bowl, beat sugar, eggs, buttermilk, oil, and vanilla extract until smooth.
- Combine: Gradually add the dry ingredients to the wet mixture.
- Incorporate coffee: Stir in hot coffee to create a smooth, pourable batter.
- Bake: Divide the batter between the prepared cake pans and bake for 30–35 minutes.
- Cool completely before assembling.
Step 2: Making the Chocolate Ganache
- Heat heavy cream in a small saucepan until it just starts to simmer. Do not boil.
- Pour over chocolate: Place chopped chocolate in a bowl and pour the hot cream over it. Let it sit for five minutes.
- Stir gently: Mix until the ganache becomes smooth and glossy. Add butter for an extra silky finish.
- Cool slightly: Allow it to thicken at room temperature before using.
Step 3: Assembling the Cake
- Trim cake layers to remove domed tops.
- Spread ganache over the first layer, then place the second layer on top.
- Coat the cake: Pour ganache over the entire cake, using an offset spatula to spread evenly.
- Chill for 30 minutes to set the ganache.

Frequently asked questions about Chocolate Ganache Cake
1. Can I make ganache ahead of time?
Yes! Chocolate ganache can be made in advance and stored in an airtight container.
- Room Temperature: Up to 2 days if kept in a cool place.
- Refrigerator: Up to 1 week (reheat gently before use).
- Freezer: Up to 3 months (thaw overnight in the fridge).
2. Why is my ganache too runny?
A thin ganache happens when the chocolate-to-cream ratio is off or it’s too warm.
- Let it sit at room temperature for 15–30 minutes to thicken.
- If it’s still runny, refrigerate for 10 minutes, stirring occasionally.
- For a thicker ganache, add more melted chocolate and mix until smooth.
3. Why is my ganache grainy or separated?
Grainy ganache is caused by overheating or improperly mixing the chocolate and cream.
- To fix it, add 1 tablespoon of warm milk or cream and stir gently.
- Use low heat and always stir slowly to avoid incorporating air bubbles.
4. Can I use milk instead of heavy cream in ganache?
Not recommended. Heavy cream provides the necessary fat content for a smooth, glossy ganache.
- If substituting, use evaporated milk or half-and-half instead.
- Coconut cream is a great dairy-free alternative.
5. What’s the best type of chocolate for ganache?
Use high-quality chocolate with at least 50% cocoa solids for the best flavor.
- Dark Chocolate (60–70% cocoa) – Best for rich, deep flavor.
- Semi-Sweet (50–60% cocoa) – Balanced sweetness, great for general use.
- Milk Chocolate (30–50% cocoa) – Sweeter, ideal for lighter ganache.
- White Chocolate – Requires less cream due to higher cocoa butter content.
6. How do I store Chocolate Ganache Cake?
- Room Temperature: Up to 2 days (if the weather is cool).
- Refrigerated: 5–7 days in an airtight container.
- Frozen: Wrap tightly and freeze for up to 3 months. Thaw in the fridge overnight.
7. How do I get a smooth and shiny ganache?
- Use finely chopped chocolate to help it melt evenly.
- Let the hot cream sit on the chocolate for 5 minutes before stirring.
- Stir gently in one direction to avoid incorporating air bubbles.
- Add 1 tablespoon of butter for an extra glossy finish.
8. Can I frost a cake with ganache instead of buttercream?
Absolutely! Ganache can be used as a frosting, glaze, or filling.
- For a pourable glaze, use a 1:1 ratio of chocolate to cream.
- For a spreadable frosting, use a 2:1 ratio (more chocolate for thickness).
- Chill before whipping for a fluffy, mousse-like texture.
9. Why does my ganache cake crack when slicing?
A hardened ganache can crack if it’s too cold or too thick.
- Let the cake sit at room temperature for 10–15 minutes before slicing.
- Use a warm knife (dip it in hot water and dry) for clean, smooth cuts.
10. Can I add flavors to ganache?
Yes! Infuse extra flavors into your ganache for a unique twist.
- Coffee or Espresso Powder – Enhances chocolate richness.
- Vanilla Extract – Adds depth to the flavor.
- Liquors (Baileys, Rum, Bourbon) – Gives a sophisticated taste.
- Orange or Raspberry Extract – For a fruity contrast.
- Cinnamon or Chili Powder – For a spicy kick.
