Instructions:
Heat the oven to 375º F. Beat the eggs in a bowl, then add the condensed milk and vanilla and stir it up. Put a few chocolate chips in the bottom of each shell, then fill them all 3/4 of the way full with the milk mixture. Bake them for 18 to 20 minutes (the tops will puff and turn golden brown, just barely), then remove and cool about 3 minutes. Sprinkle the tops with more chocolate chips. Cool in pan, then remove and store in an airtight container until it's time to eat!
NOTE: This recipe was originally called "Cinnamon Chips Gems," and instead of mini chocolate chips they used something called "cinnamon chips." I don't see that those are readily available, plus I'm allergic to cinnamon, so I altered the recipe, but you are welcome to try the original should you be so inclined!
