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