Ingredients

Scale
  • For the Cake:

    • 1 ½ cups all-purpose flour

    • 1 ½ cups granulated sugar

    • 1 teaspoon baking soda

    • 1/2 teaspoon baking powder

    • 1/2 teaspoon salt

    • 1 cup unsweetened cocoa powder

    • 2 large eggs

    • 1 cup buttermilk

    • 1/2 cup vegetable oil

    • 1 teaspoon vanilla extract

    • 1 cup boiling water

    • 1/2 cup sour cream

    For the Raspberry Truffle Filling:

    • 8 oz semisweet or bittersweet chocolate, chopped

    • 1/2 cup heavy cream

    • 2 tablespoons butter

    • 1 teaspoon vanilla extract

    • 1/2 cup raspberry puree (from fresh raspberries)

    • 1 tablespoon sugar (optional, to sweeten puree)

    For the Ganache:

    • 6 oz semisweet or bittersweet chocolate, chopped

    • 1/2 cup heavy cream

    • 1 tablespoon butter

    For the Assembly:

    • 1 cup fresh raspberries (for garnish)

    • Powdered sugar (optional, for dusting)


Instructions

  1. Prepare the Cake:

    • Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line the bottoms with parchment paper.

    • In a large mixing bowl, whisk together flour, sugar, baking soda, baking powder, salt, and cocoa powder.

    • Add the eggs, buttermilk, oil, and vanilla extract. Mix until the batter is smooth.

    • Gradually add the boiling water and mix until the batter is well-combined (it will be thin).

    • Stir in the sour cream, then divide the batter evenly between the prepared pans.

    • Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.

  2. Make the Raspberry Truffle Filling:

    • In a small saucepan, heat the heavy cream and butter over medium heat until it begins to simmer.

    • Remove from heat and add the chopped chocolate, stirring until smooth.

    • Stir in the raspberry puree and vanilla extract. Taste and add sugar if you prefer a sweeter filling.

    • Let the truffle filling cool to room temperature, then refrigerate it for about 30 minutes to thicken.

  3. Prepare the Ganache:

    • In a small saucepan, heat the heavy cream until it starts to simmer.

    • Remove from heat and add the chopped chocolate, stirring until smooth and glossy.

    • Stir in the butter and set the ganache aside to cool slightly.

  4. Assemble the Cake:

    • Once the cakes have cooled, slice each cake in half horizontally to create four layers.

    • Place the first layer of cake on a serving platter or cake stand.

    • Spread a generous amount of the raspberry truffle filling over the cake layer.

    • Place the second cake layer on top and repeat with the filling.

    • Continue layering with the cake and filling until you have used up all the layers.

    • Pour the ganache over the top of the cake, spreading it evenly with a spatula to coat the top and sides.

  5. Garnish and Serve:

    • Garnish the cake with fresh raspberries on top.

    • Optionally, dust with powdered sugar for an elegant touch.

    • Let the cake sit for 30 minutes to allow the ganache to set before slicing.

  6. Serve:

    • Slice and enjoy the rich, velvety goodness of this Chocolate Raspberry Truffle Cake.

Notes

  • This cake can be made a day in advance and refrigerated until ready to serve.

  • The raspberry puree can be made by blending fresh raspberries and straining out the seeds.

 

  • For an extra touch, drizzle some raspberry sauce on top when serving.
