Why You’ll Love Crunchy Hazelnut Chocolate Ganache Cake

  • Fast: You can have the main components prepped and in the oven in about 20 minutes.
  • Easy: It’s a simple “brown and bake” method that even beginner cooks can master.
  • Giftable: This is a sturdy dish that travels well, making it perfect for potlucks or as a “get well soon” meal.
  • Crowd-pleasing: Even people who think they don’t like hazelnuts usually fall in love with this rich, chocolatey delight!

Ingredients

  • 1 ½ cups all-purpose flour: The base for our cake, giving it that perfect texture.
  • 1 cup granulated sugar: For sweetness that balances the chocolate.
  • ½ cup unsweetened cocoa powder: This is where the chocolatey goodness comes from.
  • 1 teaspoon baking powder: Helps the cake rise beautifully.
  • ½ teaspoon baking soda: Works with the baking powder for the perfect lift.
  • ½ teaspoon salt: Enhances all the flavors in the cake.
  • ½ cup unsalted butter, softened: For a rich, buttery flavor.
  • 2 large eggs: These add moisture and structure.
  • 1 teaspoon vanilla extract: A splash of vanilla elevates the chocolate flavor.
  • 1 cup buttermilk: This adds a lovely tang and keeps the cake moist.

How to Make Crunchy Hazelnut Chocolate Ganache Cake

  1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans to ensure easy release.
  2. In a large mixing bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. The sifting helps to aerate the dry ingredients.
  3. Add the softened butter, eggs, vanilla extract, and buttermilk to the dry ingredients. Mix on medium speed until well combined and smooth. I love using a hand mixer for this as it makes the process so much quicker!
  4. Divide the batter evenly between the prepared cake pans. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Allow the cakes to cool in the pans for 10 minutes, then transfer to wire racks to cool completely.
  5. For the ganache, place the chopped dark chocolate in a heatproof bowl. In a saucepan, heat the heavy cream and butter over medium heat until it just begins to simmer. Pour the hot cream mixture over the chocolate and let it sit for 5 minutes. Stir until smooth and glossy. You’ll be amazed at how beautiful this ganache turns out!
  6. Once the cakes are completely cool, place one layer on a serving plate. Pour half of the ganache over the top and spread it evenly. Place the second cake layer on top and pour the remaining ganache over it, allowing it to drip down the sides.
  7. Sprinkle the toasted hazelnuts on top of the ganache. If desired, sprinkle with a pinch of sea salt for that extra touch of flavor.
  8. Allow the ganache to set for about 30 minutes before serving. This is the hardest part, but trust me, it’s worth the wait!

Substitutions & Additions

  • You can swap the all-purpose flour for a gluten-free blend if needed.
  • Try using milk chocolate instead of dark chocolate for a sweeter ganache.
  • Add a layer of raspberry jam between the cake layers for a fruity twist.
  • For added texture, fold in some chocolate chips into the batter.

Tips for Success

  • Make sure your butter is softened to room temperature for easy mixing.
  • Don’t overmix the batter; just mix until everything is combined to keep the cake light and fluffy.
  • Use a toothpick or skewer to check the cakes for doneness, as oven times can vary.
  • You can prepare the cake layers ahead of time and freeze them until you’re ready to assemble.

How to Store Crunchy Hazelnut Chocolate Ganache Cake

Store any leftover cake in an airtight container at room temperature for up to 3 days. If you want to keep it longer, you can refrigerate it for up to a week. Just make sure to bring it back to room temperature before serving for the best flavor and texture!

FAQs

  • Can I use different nuts instead of hazelnuts? Absolutely! Almonds or pecans would work beautifully.
  • Is this cake suitable for special diets? You can make it gluten-free and dairy-free with appropriate substitutes.
  • How can I make this cake more chocolatey? Add chocolate chips to the batter or use a chocolate frosting instead of ganache.
