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 into each cavity. Tilt and rotate to coat evenly.
02 - Place mold in refrigerator for 10 minutes to set. Apply a second coat of chocolate to ensure sturdiness, especially around edges. Chill until completely set, about 15 minutes.
03 - Combine diced strawberries, granulated sugar, and lemon juice in a bowl. Toss gently and let macerate for 15 minutes to release natural juices.
04 - In a chilled bowl, whip heavy cream with powdered sugar and vanilla extract until medium peaks form. Be careful not to overwhip.
05 - Gently fold macerated strawberries and cake cubes into whipped cream until evenly distributed.
06 - Carefully remove chocolate shells from molds. Spoon filling into half the shells, leaving space at edges. Warm a plate slightly and press rim of empty shell half onto it just until softened, then quickly seal onto filled half. Press gently to secure. Repeat for remaining eggs.
07 - Brush with edible gold leaf, drizzle with melted chocolate, or add sprinkles if desired. Refrigerate for 30 minutes before serving to allow flavors to meld.
