Ingredients
- 1 thin layer of vanilla sponge cake (cut to fit your loaf pan)
- Filling:
- 1 ½ cups heavy whipping cream, chilled
- ½ cup mascarpone or softened cream cheese (to stabilize the mousse)
- 1 whole vanilla bean, split and seeds scraped
- ¼ cup powdered sugar
- Topping & Coating:
- ½ cup white chocolate ganache or mirror glaze
- ½ cup white chocolate flakes (for the sides)
- Whipped cream rosettes
- White chocolate curls and vanilla bean pods (for garnish)
Step-by-Step Instructions
- Prepare the Foundation: Line a small loaf pan with parchment paper. Place a rectangular slice of vanilla sponge at the bottom to act as your base.
- Infuse the Cream: In a large bowl, whisk together the mascarpone (or cream cheese), powdered sugar, and the seeds from the vanilla bean until smooth and speckled.
- Whip and Fold: In a separate chilled bowl, whip the heavy cream to stiff peaks. Gently fold the whipped cream into the vanilla bean mixture until light and airy.
- Assemble: Spread the vanilla bean mousse evenly over the sponge base in the loaf pan. Use an offset spatula to create a perfectly flat top.
- Quick Chill: Place the cake in the freezer for 10 minutes to allow the mousse to set firmly before glazing.
- Glaze and Coat: Pour the white chocolate glaze over the chilled mousse. Once it sets slightly, lift the cake out using the parchment paper and press white chocolate flakes into the sides.
- Decorate: Pipe whipped cream rosettes along the top. Garnish with white chocolate curls and a decorative vanilla bean pod for a professional touch.
Pro-Tips for a Flawless Result
- Vanilla Tip: Don’t throw away the empty vanilla bean pod! Place it in a jar of sugar to create homemade vanilla sugar for future bakes.
- Perfect Peaks: Ensure your heavy cream and whisking bowl are very cold to achieve the most stable and voluminous mousse.
- Clean Cuts: For the cleanest slices that show off the beautiful vanilla specks, use a sharp knife dipped in hot water and wiped dry between each cut.
