Preheat waffle-cone maker according to the manufacturer's instructions.

Make Batter: In medium-size bowl whisk together the eggs and sugar until well combined. Add flour and salt and stir to combine. Add melted butter, milk and vanilla and stir until combined. Allow batter to rest for 10 minutes. (If the batter feels thick you can add 1-2 Tablespoons extra milk).

Cook Waffle Cones: Very lightly grease the waffle cone maker before the first use (and periodically as needed). Spoon about 3 Tablespoons (a scant 1/4 cup batter) onto the waffle-cone maker, gently spreading it into a small circle. Close the lid and cook for about 2 minutes (may vary depending on waffle cone maker) until golden. You can lift the lid to check for doneness.

Shape Cones: Immediately remove the waffle from the waffle-cone maker and quickly shape it around the cone roller. I use a paper towel to help, since the waffle will be hot! Hold the waffle around the cone for a few seconds to set its shape.

Add Chocolate Chips: We also like to add a few chocolate chips to the bottom of the cone while it's warm, to act like a “plug” and prevent any ice cream dripping through.

Cool: Place cone in a waffle cone holder to rest (or us a cooling rack). Repeat with the remaining batter. Makes about 10 cones.
