01 - Preheat oven to 400°F and line a baking sheet with parchment paper.
02 - Whisk together flour, granulated sugar, baking powder, and salt in a large bowl. Cut in cold butter until mixture resembles coarse crumbs.
03 - Whisk together egg, heavy cream, and vanilla extract in a separate bowl. Add to flour mixture and stir until just combined.
04 - Turn dough onto a lightly floured surface and gently pat into a 1-inch thick circle. Cut out rounds using a 2-inch cutter and place on prepared baking sheet.
05 - Bake for 12-15 minutes until golden. Cool completely, then crumble or cut into bite-sized pieces.
06 - Combine strawberries, granulated sugar, and lemon juice in a bowl. Let sit for 10-15 minutes to macerate.
07 - Whip heavy cream with powdered sugar and vanilla extract until soft peaks form. Refrigerate until ready to use.
08 - Melt chocolate in a heatproof bowl set over simmering water, stirring until smooth. Brush inside of Easter egg silicone molds with melted chocolate. Chill until set, about 10 minutes. Apply a second coat for sturdiness and chill again.
09 - Gently unmold chocolate shells. Fill half of the shells with layers of crumbled shortcake, macerated strawberries, and whipped cream. Top with another chocolate half to form a complete egg.
10 - Decorate with gold dust or sprinkles if desired. Keep chilled until serving.
