Ingredients
Scale
Cake Layer
- 1 cup all-purpose flour
- ½ cup unsweetened cocoa powder
- 1 tsp baking powder
- ½ tsp baking soda
- ¼ tsp salt
- ½ cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 1 tsp vanilla extract
- ½ cup buttermilk
Raspberry Mousse
- 1 cup fresh raspberries
- ¼ cup granulated sugar
- 1 cup heavy cream
- 1 tsp vanilla extract
- 4 oz dark chocolate, melted
Chocolate Ganache
- 4 oz dark chocolate, chopped
- ½ cup heavy cream
Garnish
- Fresh raspberries
Instructions
- Prep the Cake Pan: Preheat your oven to 350°F (175°C). Grease and flour an 8-inch round cake pan to prevent sticking.
- Mix Dry Ingredients: In a bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, baking soda, and salt. Set this mixture aside for later use.
- Cream Butter and Sugar: Using a mixer, beat the softened unsalted butter and granulated sugar until the mixture is light and fluffy, which should take about 3 to 5 minutes.
- Add Eggs & Vanilla: Mix in the eggs one at a time, ensuring each is fully incorporated before adding the next. Then stir in the vanilla extract to infuse flavor.
- Combine Wet & Dry Ingredients: Gradually fold the dry ingredient mixture into the wet ingredients, alternating with the buttermilk. Mix just until combined to keep the cake tender—avoid overmixing.
- Bake Cake: Pour the batter into your prepared cake pan and smooth the top evenly. Bake in the preheated oven for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean. Allow cake to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
- Prepare Raspberry Mousse: Puree the fresh raspberries with sugar and strain to remove seeds. In a separate bowl, whip the heavy cream with vanilla extract to soft peaks. Gently fold the melted dark chocolate and raspberry puree into the whipped cream. Chill this mousse mixture in the refrigerator for 30 minutes to set slightly.
- Layer the Cake: Once the cake is cooled, slice it horizontally into two layers. Spread half of the raspberry mousse evenly over the bottom layer. Place the second cake layer on top and spread the remaining mousse over it.
- Make Ganache: Heat the heavy cream until it just begins to boil. Pour the hot cream over the chopped dark chocolate and let it sit for 2 to 3 minutes. Stir the mixture until the ganache is smooth and glossy. Drizzle this ganache over the chilled cake evenly.
- Chill & Serve: Refrigerate the completed cake for at least one hour so the mousse and ganache can fully set. Garnish with fresh raspberries on top before slicing and serving. Enjoy your elegant dessert!
Notes
- Ensure the butter is softened but not melted for optimal creaming.
- Straining the raspberry puree ensures a smooth mousse free of seeds.
- Do not overmix the cake batter to maintain a tender crumb.
- Chilling the mousse before layering makes spreading easier and keeps the mousse stable.
- Use high-quality dark chocolate for the best flavor in mousse and ganache.
- Serve chilled for the best texture and flavor experience.
