Prepare both the eclair pastries and the ice cream you plan on using well in advance of wanting to serve.
Cut a small hole in the middle of the flat side of eclairs (this is where you'll pipe the ice cream in).
Using a piping bag with a small circle nozzle, pipe ice cream into each eclair until they feel full. Insert a pop stick in the end of each eclair. Freeze for at least 2 hours or until very solid.
Dip frozen eclairs into melted chocolate, place on a paper lined tray and decorate as desired. Return to the freezer in an airtight container until ready to serve. CUTE!
