These ghost meringue cookies are impossibly light, adorable, and deceptively simple to make. With just four ingredients, they are the perfect make-ahead Halloween treat that will impress guests and vanish from the dessert table.
Do not make these on a rainy or humid day, as meringue absorbs moisture and will turn sticky. Ensure your bowl and whisk are completely clean and free of any fat. Use an oven thermometer to verify the oven temperature is exactly 200°F to prevent browning or cracking. Store in an airtight container at room temperature for up to 5 days; do not refrigerate.
