Preheat the oven to 390°F and line a baking sheet with parchment paper. In a bowl, beat the egg whites with the erythritol until you get a smooth and glossy mixture.

Form each cookie by placing half a spoonful of the mixture onto the prepared baking sheet, spacing each cookie carefully. Bake at 375-390°F for about 10 minutes (or until golden brown). For a golden effect, you can use the convection setting during the last minute of baking.
