01 - Melt white chocolate in microwave-safe bowl in 20-second increments, stirring until smooth. Optionally divide and tint with pastel food coloring.
02 - Using silicone egg mold, carefully fill each cavity with melted chocolate, brushing up sides to coat evenly. Refrigerate 15 minutes to set. Apply second layer if needed for sturdy shells. Chill until firm.
03 - Mix strawberries and sugar in small bowl. Let macerate 10 minutes. Meanwhile, whisk heavy cream until stiff peaks form.
04 - Beat cream cheese until smooth. Blend in sweetened condensed milk. Gently fold in whipped cream, macerated strawberries, and crumbled cake until combined.
05 - Remove shells from molds. Fill half the shells with strawberry shortcake mixture, packing gently without overfilling.
06 - Warm plate 30 seconds in microwave. Briefly press rim of empty shell onto warm plate to slightly melt edge, then place over filled half to seal. Smooth seam with finger if needed.
07 - Decorate eggs with sprinkles, pearls, or edible gold leaf. Refrigerate until ready to serve.
