01 - Melt white or milk chocolate in a heatproof bowl set over a saucepan of simmering water, stirring until completely smooth. Spoon the melted chocolate into silicone Easter egg molds, rotating to evenly coat all sides. Refrigerate molds for 10 minutes to set the first layer. Apply a second layer of chocolate for sturdier shells. Chill molds an additional 15 minutes until fully set.
02 - Combine diced strawberries and granulated sugar in a small bowl. Let stand for 10 minutes so the strawberries release their juices.
03 - In a separate bowl, whip cold heavy cream, powdered sugar, and vanilla extract until stiff peaks form. Fold in the crushed shortcake biscuits and the macerated strawberries along with their juices.
04 - Gently unmold the chilled chocolate egg halves. Spoon the strawberry shortcake filling into one half of each shell. Align and press a matching chocolate half on top to enclose the filling. If necessary, use a small amount of melted chocolate along the edges to help seal the halves.
05 - Drizzle the assembled egg bombs with additional melted chocolate, and decorate with sprinkles, edible glitter, or colored icing if desired. Refrigerate until ready to serve.
