Special equipment: Special equipment: waffle cone iron
Whisk the eggs, heavy cream and vanilla extract in a bowl until well combined, about 1 minute. In another bowl, sift the flour, sugar and salt. Stir the dry ingredients into the cream mixture until the batter is smooth.
Heat up a waffle iron and spray it with cooking spray. Pour 1/4 cup of the batter towards the back of the iron and close the lid. Bake until golden brown, 3 1/2 minutes, depending on waffle cone maker.
Open the iron and carefully remove the browned batter with a small offset spatula. Mold as desired. After a few minutes, the waffle cup/cone will take its shape. Allow to cool completely.
