How to Make Chocolate Raspberry Mousse Cake

Ingredients

1 cup all-purpose flour
1 cup unsweetened cocoa powder
1 tsp baking soda
1 tsp salt
1 cup granulated sugar
1/2 cup unsalted butter, melted
1 large egg
1 tsp vanilla extract
1 cup hot brewed coffee or hot water
1/2 cup buttermilk
1 1/2 cups semi-sweet or dark chocolate chips
2 cups heavy whipping cream, cold
2 tbsp powdered sugar
Pinch of salt
1 cup fresh raspberries or thawed frozen raspberries
2 tbsp granulated sugar (for raspberry layer)
1 tbsp lemon juice
1 tbsp cornstarch mixed with 2 tbsp water for thickening
Fresh raspberries (for topping)
Chocolate curls or ganache drizzle (for topping)
Mint leaves or edible flowers (for topping)

Directions

Preheat oven to 350°F (175°C). Grease and line the bottom of a 9-inch springform pan. In a large bowl, whisk together flour, cocoa, baking soda, salt, and sugar. Add melted butter, egg, vanilla, hot coffee, and buttermilk. Mix until smooth. Pour batter into the prepared pan and bake for 20-24 minutes, or until a toothpick comes out clean with moist crumbs. Let the cake cool completely in the pan.
In a saucepan, combine raspberries, sugar, and lemon juice over medium heat. Stir frequently until berries break down and bubble for 5-6 minutes. Add cornstarch slurry and stir until the mixture thickens. Let it cool completely. Spread evenly over the cooled cake base and refrigerate for 30 minutes.
Melt chocolate chips in a heatproof bowl over simmering water or use a microwave in 30-second intervals. Let cool slightly. In a chilled bowl, whip the heavy cream with powdered sugar and salt until soft peaks form. Gently fold the cooled melted chocolate into the whipped cream until fully combined and fluffy.
Spread the chocolate mousse over the raspberry layer and refrigerate for 4-6 hours or until completely set, or you can chill it overnight for best results.
Remove the cake from the springform pan. Top with fresh raspberries, chocolate shavings, ganache drizzle, or mint leaves for a beautiful finish. Slice with a hot knife for clean edges and serve chilled.

How to Serve Chocolate Raspberry Mousse Cake

How to Store Chocolate Raspberry Mousse Cake

Store any leftovers in an airtight container in the refrigerator. It is best to consume the cake within 2-3 days for the freshest flavor. If it’s set properly, the layers will stay intact for a longer period.
