Ingredients

Chocolate Cake Base:

1 cup all-purpose flour

1 cup sugar

½ cup cocoa powder

1 tsp baking powder

½ tsp salt

½ cup milk

¼ cup melted butter

2 large eggs

1 tsp vanilla extract

Raspberry Mousse:

1½ cups fresh raspberries

¼ cup sugar

2 tsp powdered gelatin

2 tbsp cold water

1 cup heavy whipping cream, whipped to soft peaks

Chocolate Mousse:

6 oz dark chocolate, melted and cooled

1 cup heavy whipping cream, whipped to soft peaks

Instructions

  • Preheat oven to 350°F (175°C). Grease and flour an 8-inch cake pan. Whisk together flour, sugar, cocoa powder, baking powder, and salt. In another bowl, mix milk, melted butter, eggs, and vanilla. Combine wet and dry ingredients until smooth. Bake 25-30 minutes; cool completely.

  • Sprinkle gelatin over cold water; let bloom 5 minutes. Heat raspberries and sugar until simmering. Remove from heat; stir in gelatin until dissolved. Strain to remove seeds and cool to room temperature. Fold in whipped cream gently.

  • Melt dark chocolate; cool. Whip heavy cream to soft peaks. Fold whipped cream into chocolate until smooth.

  • Place cake base on plate. Spread raspberry mousse evenly; chill 1 hour until set. Spread chocolate mousse over raspberry layer; chill 2+ hours until firm.

  • Optionally decorate with fresh raspberries, chocolate shavings, or cocoa powder before serving.

Notes

Frozen raspberries can be used if fresh are unavailable; thaw and drain well.

Add raspberry liqueur for an adult twist.

Substitute milk or white chocolate for dark chocolate mousse.

Add crushed cookies or nuts between layers for texture.

Store refrigerated up to 3 days; avoid freezing mousse layers.
