This rich chocolate truffle cake features three tender, deeply chocolatey layers filled and frosted with fluffy cocoa buttercream and swirls of melted chocolate truffles. It’s an impressive celebration cake that’s worth the time to cool, assemble, and decorate.
Preheat the oven to 350°F (175°C). Spray three 8-inch cake pans with nonstick baking spray, line the bottoms with parchment paper rounds, and spray the parchment.
Melt the 4 ounces of chocolate in a microwave-safe bowl in 20-second intervals, stirring between intervals. Let it cool before adding it to the batter.
In a medium bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt. Stir in the granulated sugar.
In a large bowl, mix the oil, vanilla, eggs, buttermilk, and cooled melted chocolate. Slowly mix in the hot water. Add the dry ingredients and mix just until combined.
Divide the batter evenly among the prepared pans. Bake for 23–25 minutes, or until a toothpick inserted into the center of a cake comes out clean.
Let the cakes rest in their pans for 10 minutes, then turn them out onto cooling racks. Cool completely before frosting.
Sift the powdered sugar and cocoa powder together. In a large bowl, beat the room-temperature butter on high speed for 3 minutes. Add the sugar mixture in two additions, mixing on low speed after each. Add the vanilla and salt, then beat on high until fluffy.
Just before assembling the cake, melt the 10 truffles in a microwave-safe bowl in 20-second intervals, stirring between intervals.
Use a serrated knife to trim the domed tops from the cooled cake layers so they stack evenly.
Place one cake layer on a serving plate. Spread 3/4 cup of frosting over it, drizzle with half of the melted truffles, and gently swirl the truffle into the frosting with a butter knife. Repeat with the second layer and remaining melted truffles.
Place the final cake layer on top with its bottom facing up. Spread a thin layer of frosting over the top and sides, then freeze the cake for 15 minutes to set the crumb coat.
Frost the cake with the remaining frosting and decorate the top with additional truffles.
