How to Make Chocolate Ganache Cake

Quick Overview

This Chocolate Ganache Cake combines a foolproof chocolate cake recipe with an irresistibly smooth ganache frosting that creates a professional finish with minimal effort. The entire process takes about 2.5 hours, including baking and cooling time, though the active preparation is only about 40 minutes—making this an achievable project even for busy bakers.

Key Ingredients

• 2 cups all-purpose flour
• 2 cups granulated sugar
• 3/4 cup premium cocoa powder
• 2 teaspoons baking soda
• 1 teaspoon baking powder
• 1/2 teaspoon salt
• 2 large eggs (room temperature)
• 1 cup buttermilk
• 1/2 cup vegetable oil
• 2 teaspoons vanilla extract
• 1 cup hot coffee or boiling water
• For the ganache: 12 ounces high-quality dark or semi-sweet chocolate
• 1 cup heavy cream
• 2 tablespoons unsalted butter (optional, for shine)

Step-by-Step Instructions

1. Prepare the pans: Preheat your oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper.
2. Mix dry ingredients: In a large bowl, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt until well combined.
3. Combine wet ingredients: In a separate bowl, beat eggs, then add buttermilk, oil, and vanilla extract, mixing until smooth.
4. Create the batter: Gradually add the wet ingredients to the dry ingredients, mixing on low speed until just combined. Slowly pour in the hot coffee, mixing on low until smooth (the batter will be thin).
5. Bake the cakes: Divide the batter evenly between prepared pans and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Cool in pans for 10 minutes, then remove to wire racks to cool completely.
6. Make the ganache: Finely chop the chocolate and place in a heatproof bowl. Heat the heavy cream just until it begins to simmer (don't boil). Pour over chocolate and let sit for 3 minutes, then gently stir until completely smooth. Add butter if using and stir until melted. Allow to cool until thickened but still pourable.
7. Assemble and frost: Place one cake layer on a serving plate. Pour 1/3 of the ganache over the top, spreading to the edges. Place the second layer on top. Pour remaining ganache over the cake, allowing it to drip down the sides. Use an offset spatula to smooth the top and sides if needed.

What to Serve Chocolate Ganache Cake With

Elevate your Chocolate Ganache Cake experience by pairing it with homemade vanilla bean ice cream for a classic contrast, or fresh raspberry coulis for a fruity brightness that cuts through the chocolate richness. For an adult gathering, serve alongside espresso martinis or port wine which complement the deep chocolate notes beautifully. For Graduation Cakes celebrations, consider adding a festive champagne toast to complete the special occasion.

Top Tips for Perfecting Chocolate Ganache Cake

• Use room temperature ingredients for the cake batter to ensure proper emulsification and even baking.
• The coffee enhances the chocolate flavor without making the cake taste like coffee; decaf works perfectly if caffeine is a concern.
• For the smoothest ganache, chop chocolate very finely and ensure cream is hot but not boiling when poured over.
• Allow the ganache to cool to the right consistency before pouring—it should coat the back of a spoon but still flow easily.
• For Graduation Cakes, personalize with school colors using colored white chocolate decorations or themed toppers.
• Chill the cake for 30 minutes before serving for cleaner slices.

Storing and Reheating Tips

This Chocolate Ganache Cake can be stored at room temperature for up to 2 days in a cake dome or airtight container. For longer storage, refrigerate for up to 5 days, but allow slices to come to room temperature before serving for the best flavor and texture. The cake also freezes beautifully—wrap individual slices tightly in plastic wrap and freeze for up to 3 months. Thaw overnight in the refrigerator and bring to room temperature before enjoying. The ganache may lose some shine after refrigeration, but a quick pass with a warm knife over the surface can restore its glossy appearance.

FAQs

Can I make this Chocolate Ganache Cake in advance for a graduation party?
Absolutely! You can bake the cake layers up to 3 days ahead and store them wrapped in plastic at room temperature. The ganache can be prepared 24 hours in advance and gently rewarmed. Assemble the day before the graduation celebration for the freshest result.
What's the best chocolate to use for ganache?
For the best ganache, use high-quality chocolate bars (60-70% cocoa) rather than chocolate chips, which contain stabilizers that can affect the texture. Brands like Ghirardelli, Lindt, or Guittard work exceptionally well for a smooth, glossy finish.
Can I turn this into cupcakes instead of a layer cake?
Yes! This recipe makes approximately 24 cupcakes. Bake at the same temperature but reduce time to 18-22 minutes. Once cooled, dip the tops in ganache for an elegant finish or pipe it on for a more decorated look—perfect for individual Graduation Cakes treats.
