01 - Melt chopped chocolate in a heatproof bowl set over simmering water using the double boiler method until glossy and smooth. Spoon the melted chocolate into silicone Easter egg molds, ensuring even coverage by swirling and tilting. Refrigerate molds for 10 minutes to set, then apply a second coating of chocolate to reinforce the shells. Chill for an additional 15 minutes until fully firm.
02 - Combine diced strawberries with granulated sugar in a small bowl, stirring to coat. Allow the mixture to rest for 10 minutes so the strawberries release their juices.
03 - In a medium mixing bowl, whip cold heavy cream with powdered sugar and vanilla extract using an electric mixer or hand whisk until stiff peaks develop. Gently fold in the crushed shortcake biscuits and the macerated strawberry mixture until evenly blended.
04 - Carefully unmold the chilled chocolate egg halves. Spoon generous amounts of the strawberry shortcake filling into one half of each chocolate egg. Gently place the matching half on top, sealing the perimeter with a small amount of melted chocolate if necessary. Allow to chill until fully set.
05 - Drizzle the assembled egg bombs with additional melted chocolate, sprinkles, edible glitter, or colored icing as desired. Refrigerate until ready to serve for best texture.
