Ingredients

For the Chocolate Cake:

1 cup all-purpose flour

1 cup granulated sugar

1/2 cup unsweetened cocoa powder

1 tsp baking soda

1/2 tsp baking powder

1/2 tsp salt

1/2 cup vegetable oil

2 large eggs

1 tsp vanilla extract

1 cup buttermilk

1/2 cup hot coffee or water

For the Dark Chocolate Mousse:

8 oz dark chocolate (60–70% cocoa), chopped

2 tbsp unsalted butter

2 cups heavy cream, chilled

1/4 cup powdered sugar

1 tsp vanilla extract

For Assembly:

1 1/2 cups fresh raspberries

Additional raspberries and chocolate shavings for garnish

Instructions

Make the Cake:

Preheat oven to 350°F (175°C). Grease and line two 8-inch round cake pans.

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

Add oil, eggs, vanilla, and buttermilk; whisk until smooth. Stir in hot coffee until combined.

Divide batter evenly between pans and bake for 25–30 minutes, until a toothpick inserted in the center comes out clean. Cool completely.

Make the Mousse:

Melt dark chocolate and butter together in a heatproof bowl over simmering water or in short microwave bursts. Let cool slightly.

Whip cream, powdered sugar, and vanilla to soft peaks. Fold in melted chocolate gently until mousse is smooth.

Assemble the Cake:

Place one cake layer on a serving plate. Spread a layer of mousse, then scatter fresh raspberries over it.

Top with second cake layer, spread remaining mousse evenly over top and sides.

Garnish with extra raspberries and chocolate shavings. Chill for at least 2 hours before serving.

Notes

Use high-quality dark chocolate for the best flavor.

For a stronger raspberry flavor, add a thin layer of raspberry jam between cake layers.

Best served chilled and consumed within 3 days.
