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, tilting and rotating to coat evenly. Refrigerate for 10 minutes to set, then 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. Be careful not to overwhip the mixture.
04 - Gently fold macerated strawberries and cake cubes into the whipped cream until just combined, being careful not to deflate the cream.
05 - Carefully remove chocolate egg shells from molds. Spoon strawberry shortcake filling into half of the shells, leaving space at edges. Warm a plate or pan slightly and press the edge of an empty shell half onto it just until rim softens, then 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 if desired. Chill assembled egg bombs for 30 minutes before serving. Store in airtight container in refrigerator for up to 24 hours.
