Spray insides of both sides of egg mold and along rims with cooking spray. Close mold, matching up rims of egg halves. Snap each of the 6 individual egg halves together until each egg is firmly sealed. Inspect each egg to make sure it is closed and sealed.
Place mold, fill-side up, on tray.
Add boiling water to gelatin mix in large bowl; stir 3 min. until completely dissolved.
Pour into measuring cup with pour spout. Immediately pour into mold through fill-holes until each egg is filled just to top of egg shape. (Any remaining gelatin mixture can be poured into custard cup.)
Refrigerate 3 hours or until firm. Open mold using a dull flat knife to gently pry between the halves of each egg. (Do not pull on the handle.) Turn mold over and shake gently to unmold eggs. Keep refrigerated.
