Ingredients
- 1 thin layer of vanilla sponge cake (cut to fit a loaf pan)
- Filling:
- 1 ½ cups heavy cream, whipped to soft peaks
- 1 cup mascarpone or cream cheese, softened
- ½ cup powdered sugar
- ½ cup fresh raspberry purée (strained to remove seeds)
- 1 tsp vanilla extract or paste
- Topping & Coating:
- ½ cup raspberry mirror glaze (melted and cooled to room temp)
- Fresh raspberries for garnish
- Whipped cream for rosettes
- White cake crumbs or shredded coconut (for the sides)
Step-by-Step Instructions
- Prepare the Base: Line a loaf pan with parchment paper and place a rectangular slice of vanilla sponge at the very bottom.
- The Vanilla Mousse: Beat the mascarpone and powdered sugar until smooth, then gently fold in the whipped cream and vanilla.
- Create the Gradient: Divide the cream mixture in half. Keep one half vanilla; stir the raspberry purée into the other half to create a pink mousse.
- Assemble the Layers: Spread the vanilla mousse over the sponge, then top with a smooth, even layer of the raspberry mousse. Freeze for at least 4 hours to ensure a perfectly level surface.
- The Mirror Glaze: Pour the warm (but not hot) raspberry glaze over the frozen mousse cake, letting it flow evenly to the edges.
- The Side Finish: Once the glaze is set, carefully remove the cake from the pan and press white cake crumbs or coconut into the sides for a clean, textured look.
- Final Flourish: Pipe uniform whipped cream rosettes down the center and place a fresh, plump raspberry atop each one.
- Thaw & Serve: Move the cake to the refrigerator to thaw for 1 hour before slicing with a warm knife for the cleanest edges.
Pro-Tips for a Perfect Finish
- Seedless is Secret: Always strain your raspberry purée through a fine-mesh sieve; seeds will interrupt the smooth texture of the mousse and the clarity of the glaze.
- Temperature Control: Ensure the cake is completely frozen before glazing; the cold temperature helps the glaze set instantly into a perfect mirror finish.
- Stabilize the Mousse: If you need the cake to sit out for a while, you can fold a small amount of bloomed gelatin into the mousse for extra stability.
