Ingredients
- 1 thin layer of vanilla sponge cake (for the base)
- Filling:
- 8 oz cream cheese, softened
- 1 cup heavy whipping cream, chilled
- 1/2 cup powdered sugar
- 1/2 cup blueberry preserves or thick purée
- Topping & Coating:
- 1/4 cup blueberry glaze (strained preserves)
- 1/2 cup shredded coconut (for the sides)
- Fresh blueberries for garnish
- Whipped cream for rosettes
- Fresh mint (optional)
Step-by-Step Instructions
- Prepare the Base: Line a small loaf pan with parchment paper. Place a rectangular slice of vanilla sponge at the bottom.
- The Mousse Base: In a large bowl, beat the softened cream cheese and powdered sugar until smooth. In a separate chilled bowl, whip the heavy cream to stiff peaks, then gently fold it into the cream cheese mixture.
- The Blueberry Swirl: Pour half of the white mousse over the sponge. Spoon the blueberry purée or preserves over the layer, then top with the remaining mousse. Use a toothpick to gently swirl the berry layer into the cream for a marbled effect.
- Smooth and Set: Level the top with a spatula and pop it into the freezer for 10 minutes to help the surface set quickly.
- The Glaze: Spread a thin, even layer of blueberry glaze over the top for a professional, glossy finish.
- Texture the Sides: Carefully lift the cake from the pan using the parchment paper. Press shredded coconut into the sides of the mousse until fully coated.
- Final Flourish: Pipe elegant whipped cream rosettes down the center and place a fresh blueberry on each one. Finish with a small sprig of mint.
Pro-Tips for a Flawless Finish
- Strain for Shine: If your blueberry preserves have seeds or large fruit chunks, pass them through a fine-mesh sieve before using them as a glaze to ensure a smooth, mirror-like top.
- Warm Knife Slicing: To maintain those beautiful, sharp layers seen in the image, dip your knife in hot water and wipe it dry between every single cut.
- Stability Hack: Ensure your heavy cream is very cold before whipping; this ensures the mousse stays firm enough to hold its shape after you remove it from the mold.
