01 - Chop the chocolate into small pieces and place into a heatproof bowl. Melt gently over a double boiler or microwave in 20-second intervals, stirring frequently until smooth.
02 - Using a clean, dry pastry brush or spoon, coat the inside of 8 clean food-grade egg molds with a layer of melted chocolate and refrigerate for 10 minutes to set.
03 - Apply a second layer of chocolate to the molds to strengthen the shells. Chill again until fully set, about 10 minutes.
04 - Carefully remove the hardened chocolate egg halves from the molds.
05 - Place a small toy, wrapped in plastic wrap if necessary, inside half of the chocolate shells.
06 - Warm a plate slightly. Press the edges of two halves against the warm plate to melt slightly, then quickly press them together to seal and form a complete egg. Hold until set.
07 - Repeat sealing with remaining halves and toys, and allow the completed eggs to fully set at room temperature or in the refrigerator before wrapping or serving.
