Method
- Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans with butter or cooking spray, lining the bottoms with parchment paper.
- In a large bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt until evenly distributed.
- In another bowl, beat sugar and eggs until light and fluffy (3-4 minutes), then mix in buttermilk, oil, and vanilla until smooth.
- Gradually combine wet and dry ingredients until just mixed, then stir in the boiling water. The batter will be thin - this is correct and creates the moist texture.
- Divide batter between prepared pans and bake for 25-30 minutes until a toothpick inserted in the center comes out with a few moist crumbs.
- Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely before assembling.
- Beat cream cheese until smooth and fluffy, then gradually add powdered sugar and vanilla, mixing until well combined.
- Gently fold in the mashed raspberries, being careful not to overmix. You want to see pretty raspberry swirls throughout the filling.
- Heat heavy cream until it just begins to simmer, remove from heat and pour over finely chopped chocolate. Let sit for 2 minutes, then stir from center outward until smooth and glossy. Cool to about 90°F (use an instant-read thermometer or test that it coats a spoon but flows freely) for perfect dripping consistency.
- Place one cake layer on serving plate and spread raspberry cream cheese filling evenly over top, leaving a ½-inch border. Position second layer on top and gently press to seal. Chill for 10 minutes to help set the filling.
- Pour ganache over top of cake, allowing it to drip naturally down the sides. Garnish with fresh raspberries and chocolate shavings for a professional finish.
Notes
Dutch-process cocoa powder is essential for this recipe as it provides the deep chocolate flavor and proper texture. If you only have natural cocoa powder, reduce the baking soda to 1 teaspoon and add ¼ teaspoon baking powder. Ensure all ingredients are at room temperature for the best texture and mixing results. The ganache temperature is crucial for achieving the perfect drip consistency - it should coat the back of a spoon but still flow freely. For the raspberry filling, strain out some seeds if you prefer a smoother texture. The ganache can be made up to 3 days ahead and gently rewarmed before use. If using frozen raspberries, thaw them completely and drain excess liquid before mashing.
