01 - Melt the chopped chocolate in a heatproof bowl set over a saucepan of simmering water until fully smooth. Spoon the melted chocolate into silicone Easter egg molds, swirling to coat the interior evenly. Place the molds in the refrigerator for 10 minutes to allow the chocolate to set. Repeat the coating process for a sturdy shell, then chill for an additional 15 minutes until firm.
02 - Combine the diced strawberries and granulated sugar in a small bowl. Allow the mixture to stand for 10 minutes, enabling the strawberries to macerate and release their juices.
03 - Beat the cold heavy cream with powdered sugar and vanilla extract in a mixing bowl using an electric mixer or hand whisk until stiff peaks form. Gently fold in the crushed shortcake biscuits and macerated strawberries until thoroughly combined.
04 - Carefully unmold the chocolate egg shells. Fill one half of each egg with the prepared strawberry shortcake mixture. Align and press the remaining halves on top, using a small amount of melted chocolate along the seam to seal if necessary.
05 - Drizzle each assembled egg with additional melted chocolate if desired, then finish with sprinkles, edible glitter, or colored icing. Refrigerate the eggs until ready to serve.
