Preheat oven to 375 degrees if using a conventional oven (350 degrees if using convection/bake mode oven). Spray forty-eight of 1 ¾” diameter muffin cups (2 pans) with nonstick spray.
Whisk eggs thoroughly in a large bowl and then add remaining ingredients and whisk to blend well.
Fill each cup to just below the top (less than a full tablespoon) with batter.
Bake tarts until golden and puffed. This will be about 20 minutes, but may vary based on oven calibration. Keep a close eye on them so as not to burn them. Remove from pans onto cooling rack after 2-3 minutes of in pan cooling.
