Gather the ingredients. Preheat the oven to 375 F.
In a large mixing bowl, combine the sugar, egg whites, and salt and mix until the sugar dissolves. (You do not need to whip these ingredients until peaks form.)
Beat in the melted butter, flour, and vanilla until well blended.
Measure 2 tablespoons of the batter and drop onto a parchment-lined baking sheet. Place 4 scoops on each sheet, spaced far apart from each other as the batter will spread.
Gently spread each scoop of batter into a 4-inch diameter circle. Bake in the oven for 10 minutes, or until the cookies are lightly browned.
Remove the sheet from the oven and quickly form the warm, pliable cookie around a cone-shaped mold. You must work very quickly before the cookies set. If the cookies are too hot to handle, ease them over and around the mold using a tea towel.
Alternately, the baked cookies can be draped over an inverted muffin tin to create ice cream bowls.
Allow the ice cream cones or edible bowls to cool completely before filling with ice cream.
Enjoy your homemade treat!
