How to Make White Chocolate Raspberry Mousse Cake
Ready to get started? Follow these simple steps:
- Prepare the Cake:
- Preheat your oven to 350°F (175°C) and grease and flour a 9-inch round cake pan.
- In a large bowl, mix together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- Add in the softened butter, eggs, vanilla extract, and buttermilk. Mix until you have a smooth batter.
- Pour the batter into the prepared cake pan and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let it cool completely.
- Make the Raspberry Mousse:
- In a small saucepan, combine the raspberries and sugar over medium heat. Cook until the raspberries break down and the mixture thickens, then strain and let cool.
- Melt the white chocolate in a double boiler or microwave and let it cool slightly.
- In a large mixing bowl, whip the heavy cream until soft peaks form.
- Dissolve the gelatin in cold water and let it sit for 5 minutes, then gently heat until dissolved.
- Combine the melted white chocolate, raspberry puree, and gelatin mixture. Gently fold in the whipped cream until fully incorporated.
- Assemble the Cake:
- Slice the cooled cake in half horizontally, placing one layer on a serving plate.
- Spread half of the raspberry mousse over the first layer. Place the second layer on top and cover with the remaining mousse.
- Refrigerate for at least 4 hours to set.
- Prepare the Ganache:
- Heat the heavy cream in a small saucepan until just simmering, then pour it over the chopped white chocolate. Let it sit for 5 minutes, then stir until smooth and glossy. Allow to cool slightly.
- Finish the Cake:
- Once the mousse is set, pour the ganache over the top of the cake, letting it drizzle down the sides if desired.
- Chill the cake for another hour before serving. Decorate with fresh raspberries if you like, then cut into slices and enjoy!
Substitutions & Additions
If you’re looking to switch things up a bit, here are some ideas:
- Use dark chocolate instead of white for a richer flavor.
- Add a splash of raspberry liqueur to the mousse for an adult twist.
- Substitute the fresh raspberries with strawberries or blueberries for a different fruity flavor.
Tips for Success
Here are some friendly tips to make sure your cake turns out perfectly:
- Make sure your ingredients are at room temperature for the best results.
- Be patient while letting the mousse set; it ensures a beautiful texture.
- If the ganache is too thick, you can reheat it gently to get the desired consistency.
