01 - Melt the chopped chocolate in a heatproof bowl set over a saucepan of simmering water, stirring until completely smooth. Spoon a layer of melted chocolate into each cavity of the silicone egg molds, rotating to coat the sides evenly. Refrigerate for 10 minutes to set the first layer. Repeat with a second coating for added strength, then chill until fully set, approximately 15 minutes.
02 - Combine diced strawberries and granulated sugar in a bowl. Allow to macerate for 10 minutes until the berries release their juices.
03 - In a separate bowl, beat cold heavy cream with powdered sugar and vanilla extract using an electric mixer until stiff peaks form. Gently fold in crushed shortcake biscuits and the prepared macerated strawberries, mixing until evenly combined.
04 - Carefully remove the set chocolate egg halves from the molds. Spoon generous portions of the strawberry shortcake filling into one half of each shell. Position the matching half on top and seal together, using a small amount of melted chocolate if necessary.
05 - Drizzle with additional melted chocolate and finish with decorative sprinkles, edible glitter, or colored icing as desired. Keep chilled until serving.
