Ingredients

This recipe makes a 9-inch round cake or 8×8-inch square pan.

For the Cake:

• 1 cup (2 sticks) unsalted butter
• 8 oz semi-sweet chocolate, chopped
• 1 cup granulated sugar
• ¼ cup brown sugar
• 4 large eggs
• 1 tsp vanilla extract
• ½ cup all-purpose flour
• ¼ tsp salt

For the Chocolate Ganache:

• ½ cup heavy cream
• 8 oz semi-sweet or dark chocolate, chopped
• 1 tsp butter (optional, for shine)

Optional Garnishes:

• Chocolate shavings or curls
• Cocoa powder dusting
• Crushed nuts (hazelnuts or almonds)

Step 1: Prep the Pan

Preheat your oven to 350°F (175°C).

Grease your pan and line with parchment paper for easy removal. If using a round cake pan, lightly dust with cocoa powder to prevent sticking.

Step 2: Melt Chocolate and Butter

In a heatproof bowl over a double boiler or in the microwave (20–30 second intervals), melt the butter and chopped chocolate together. Stir until smooth and glossy.

Set aside to cool slightly—this ensures your eggs won’t scramble when added.

Step 3: Mix the Batter

In a large bowl, whisk together granulated sugar, brown sugar, and eggs until smooth.

Add the melted chocolate and butter mixture, stirring until fully combined.

Mix in vanilla extract.

Sift in flour and salt, then fold gently until just combined. Be careful not to overmix—the batter should be thick, shiny, and fudgy.

Step 4: Bake

Pour the batter into the prepared pan and smooth the top.

Bake at 350°F (175°C) for 25–30 minutes for an 8×8-inch pan, or 30–35 minutes for a 9-inch round pan.

The cake should be set around the edges but still slightly soft in the center. This ensures a fudgy, truffle-like texture.

Cool completely in the pan before adding ganache.

Step 5: Prepare the Ganache

Place chopped chocolate in a heatproof bowl. Heat heavy cream until just simmering and pour over the chocolate.

Let sit 1–2 minutes, then stir until smooth. Add butter if you want a glossy finish.

Allow ganache to cool slightly so it’s pourable but not too runny.

Step 6: Assemble the Cake

Pour the ganache over the cooled cake and spread evenly with a spatula.

Optional: sprinkle chocolate shavings, dust with cocoa powder, or add crushed nuts on top.

Chill in the refrigerator for 30–60 minutes to set the ganache.

Texture & Flavor Breakdown

• Cake: Dense, fudgy, and moist, like biting into a rich chocolate truffle
• Ganache: Smooth, creamy, and slightly firm once set
• Garnish: Adds texture and visual appeal, balancing the richness

Every bite is luxurious, deeply chocolatey, and melts in your mouth—exactly what a truffle cake should do.

Common Mistakes to Avoid

• Overbaking: The cake will become dry. Fudgy is the goal.
• Adding eggs to hot chocolate: Can scramble the batter. Let chocolate cool slightly first.
• Overmixing flour: Creates a dense, heavy cake instead of fudgy.
• Pouring ganache on warm cake: Can seep into cracks. Cool cake first.
• Skipping parchment or greasing: Cake can stick and break apart when removing.

Variations & Flavor Twists

• Coffee Boost: Add 1–2 tsp instant coffee to intensify chocolate flavor.
• Liqueur Addition: Stir in 1 tbsp of Kahlua, Baileys, or Grand Marnier.
• Chocolate Layer Cake: Bake in two layers and add ganache between layers.
• Nutty Upgrade: Fold in chopped toasted hazelnuts or almonds for crunch.
• Salted Chocolate: Sprinkle flaky sea salt on ganache before it sets.

This cake is versatile—you can adjust it to suit your flavor preferences and occasion.

Storage & Tips

• Room Temperature: 2–3 days in an airtight container.
• Refrigerator: Up to 5 days; bring to room temperature before serving.
• Freezer: Wrap tightly; freeze for up to 2 months. Thaw overnight in the fridge.

Pro tip: Chocolate flavors deepen after a day, so sometimes it tastes even better the next day.

FAQ

Can I use milk chocolate instead of semi-sweet?
Yes, but it will be sweeter and less intense.

Can I make mini cakes or cupcakes?
Absolutely! Adjust baking time to 15–20 minutes depending on size.

Why is my cake dense instead of fudgy?
Likely overbaked or overmixed flour. Fudgy texture comes from careful mixing and slightly underbaked center.

Can I use dark chocolate instead?
Yes, 70% dark chocolate gives a more intense, less sweet flavor.

Do I have to chill the ganache?
Chilling helps it set and makes slicing easier, but you can serve slightly soft if preferred.
