Ingredients
List of Ingredients
- 1 ½ cups all-purpose flour
- 1 cup granulated sugar
- ½ cup unsweetened cocoa powder
- 1 teaspoon baking soda
- ½ teaspoon salt
- 1 cup buttermilk (or yogurt)
- ½ cup vegetable oil
- 2 large eggs

- 1 cup fresh raspberries (plus extra for garnish)
- 8 ounces semi-sweet chocolate, finely chopped
- 1 cup heavy cream
- 2 tablespoons powdered sugar
- 1 teaspoon vanilla extract (for the truffle ganache)
Gather these ingredients before you start. Each one plays an important role in making the cake rich and flavorful.
All-purpose flour gives the cake its structure. Granulated sugar adds sweetness, while cocoa powder provides that deep chocolate flavor. Baking soda helps the cake rise.
Salt enhances all the flavors. Buttermilk or yogurt adds moisture and tanginess. Vegetable oil keeps the cake soft and rich. Eggs act as a binder, giving the cake its shape.
Vanilla extract adds a warm aroma. Boiling water helps blend the batter smoothly, making it light. Fresh raspberries add a burst of tartness that contrasts beautifully with the chocolate.
Semi-sweet chocolate and heavy cream create a smooth ganache. The powdered sugar sweetens it just right. Lastly, a bit of extra vanilla enhances the ganache's flavor.
With these ingredients, you can create a delightful dessert everyone will love.

Step-by-Step Instructions
Preheating the Oven
First, preheat your oven to 350°F (175°C). This helps the cake rise correctly. Grease two 9-inch round cake pans. Dust them with flour to stop the cake from sticking. The right oven temperature is key for even baking.
Mixing the Dry Ingredients
In a large bowl, sift together 1 ½ cups of all-purpose flour, 1 cup of granulated sugar, ½ cup of unsweetened cocoa powder, 1 teaspoon of baking soda, and ½ teaspoon of salt. Sifting helps make the cake fluffy by breaking up clumps. Mixing the leavening agents ensures they spread evenly.
Incorporating Wet Ingredients
In a separate bowl, whisk 1 cup of buttermilk (or yogurt), ½ cup of vegetable oil, 2 large eggs, and 1 teaspoon of vanilla extract. This mixture adds moisture and richness to your cake. Make sure to mix it well to combine the flavors.
Combining Batter
Gradually add the wet ingredients to the dry mixture. Stir gently until just combined. The batter may be lumpy, and that’s okay! Next, pour in 1 cup of boiling water and stir until smooth. The boiling water helps to create a moist cake.
Baking and Cooling
Pour the batter into the prepared pans. Bake for 30 to 35 minutes. To check for doneness, stick a toothpick in the center. If it comes out clean or with a few moist crumbs, it’s done. Let them cool for 10 minutes in the pans before moving to wire racks.
Preparing Truffle Ganache
For the ganache, heat 1 cup of heavy cream in a small saucepan over medium heat. Bring it to a gentle simmer. Remove from heat and add 8 ounces of finely chopped semi-sweet chocolate and 2 tablespoons of powdered sugar. Let it sit for a few minutes to melt the chocolate. Whisk until smooth and add 1 teaspoon of vanilla extract. Let it cool until thickened.
Assembling the Cake
Once the cakes cool completely, place one layer on a serving plate. Spread a generous layer of ganache on top and scatter fresh raspberries over it. Carefully place the second layer on top and cover the entire cake with the remaining ganache.
Garnishing
For a beautiful finish, decorate the top and sides with extra fresh raspberries. You can also dust cocoa powder on top for a touch of elegance. This makes the cake look as great as it tastes!
Tips & Tricks
Baking Tips
- Ensuring even baking: To get an even bake, make sure your oven is preheated. Use an oven thermometer to check the temperature. Place your cake pans in the center of the oven. This helps the heat circulate evenly.
- Keeping cakes moist: Adding buttermilk or yogurt keeps the cake moist. Using boiling water in the batter also helps. Avoid opening the oven door too often. This will help maintain a steady temperature.
Ganache Perfection
- Thickening tips: If your ganache is too thin, let it cool longer. You can also add more chocolate. Stir it well until smooth and thick.
- Flavor enhancements: Add a splash of espresso or orange zest. These flavors boost the chocolate taste. You can also use flavored extracts like almond or raspberry for a twist.
Presentation Techniques
- Serving suggestions: Slice the cake with a warm knife for clean cuts. Serve each piece on a nice plate. This makes a big difference in how it looks.
- Creative plating ideas: Drizzle raspberry sauce around the cake slice. Use pureed raspberries mixed with sugar. Garnish with fresh raspberries on top. This adds color and flair.

Variations
Chocolate Raspberry Cake Remix
You can really switch things up with this cake! Adding a bit of orange zest can bring a bright flavor. Just mix in a teaspoon of zest into the batter. It pairs well with the chocolate. For frosting options, you can use cream cheese or a fluffy whipped cream. Both give a nice twist that enhances the cake.
Gluten-Free Adaptation
If you want to make this cake gluten-free, swap the all-purpose flour for a gluten-free blend. Look for blends that include xanthan gum for best results. You may need to bake a bit longer too, so keep an eye on it. A toothpick test is your best friend here!
Vegan Version
To make a vegan version, replace the eggs with flax eggs. Mix one tablespoon of flaxseed meal with three tablespoons of water for each egg. Use almond milk or soy milk instead of buttermilk. For the ganache, substitute heavy cream with coconut cream. You might need to bake it a little longer to set properly. Enjoy this plant-based treat!
Storage Info
How to Store Leftovers
Store leftover Chocolate Raspberry Truffle Cake in the fridge. Wrap it well in plastic wrap. If you leave it out, it will dry out. Refrigeration keeps it fresh for up to four days. If you want to enjoy it later, freezing is a great option.
Freezing Instructions
To freeze the cake layers, let them cool completely. Wrap each layer tightly in plastic wrap. Then, put them in a freezer bag. This helps prevent freezer burn. You can freeze the layers for up to three months. When you're ready to eat, thaw them in the fridge overnight. This keeps the texture nice.
Reheating Tips
To reheat the cake, preheat your oven to 350°F (175°C). Place the cake on a baking sheet covered with foil. Heat for about 10 to 15 minutes. This keeps the cake moist and warm. After reheating, serve it with a drizzle of raspberry sauce. It will taste fresh and delightful!
FAQs
Can I use frozen raspberries instead of fresh?
Yes, you can use frozen raspberries. They work well, but they can change the cake's texture. Frozen raspberries may be softer and might release more juice. This can make your cake moist, which is good, but it might be too wet. If you choose frozen, add them straight from the freezer to the batter.
How can I make the cake more chocolaty?
To boost the chocolate flavor, add more cocoa powder. You can use about 3/4 cup instead of 1/2 cup. You might also try adding chocolate chips into the batter. Semi-sweet or dark chocolate chips work best. This makes every bite extra rich and chocolaty.
Why is my cake too dry?
Dry cake can come from a few common issues. One reason is overbaking. Always check the cake a few minutes before the timer goes off. Another reason is not enough liquid. Make sure you measure your ingredients correctly. Adding a bit more buttermilk can help too.
Can I use other types of chocolate for the ganache?
Yes, you can use different chocolates. Dark chocolate gives a richer flavor. Milk chocolate makes it sweeter. White chocolate offers a creamy taste. Each choice changes the cake's flavor profile, so pick what you love best.
How long does the cake last?
The cake stays fresh for about three days at room temperature. You can keep it in the fridge for up to a week. If you want it to last longer, store it in an airtight container. This helps keep it moist and tasty.
Can I make this cake ahead of time?
You can make the cake a day ahead. Just bake and cool it, then wrap it tightly in plastic wrap. You can also freeze the layers for up to a month. To thaw, put them in the fridge overnight. This makes it easy to prepare for parties or special events.
