01 - Melt white chocolate gently in a heatproof bowl over simmering water or microwave in 20-second bursts, stirring until smooth. Using a food-safe silicone Easter egg mold (6 halves), spoon or brush a generous layer of melted chocolate into each cavity. Tilt and rotate to coat evenly. Refrigerate for 10 minutes to set. Apply a second coat of chocolate for sturdiness, especially around edges. Chill until completely set, about 15 minutes.
02 - Combine diced strawberries, granulated sugar, and lemon juice in a bowl. Toss gently and let macerate for 15 minutes to release natural juices.
03 - In a chilled bowl, whip heavy cream with powdered sugar and vanilla extract until medium peaks form. Avoid overwhipping to maintain light texture.
04 - Gently fold macerated strawberries and cake cubes into whipped cream until evenly distributed.
05 - Carefully remove chocolate egg shells from molds. Spoon strawberry shortcake filling into half of the shells, leaving space at edges. Warm a plate slightly and press edge of an empty shell half onto it just until rim softens. Quickly seal onto a filled half, pressing gently. Repeat for all eggs.
06 - Brush with edible gold leaf, drizzle with melted chocolate, or top with sprinkles as desired.
07 - Refrigerate for 30 minutes before serving to allow flavors to meld and chocolate to firm.
