These ghost meringue cookies are light, airy, and perfect for Halloween. Made with just three simple ingredients, they look fancy but are incredibly easy to make.
For best results, use room temperature egg whites and ensure your bowl is completely clean and grease-free. A tiny splash of vinegar or cream of tartar stabilizes the meringue. Avoid making these on humid days. Store in an airtight container at room temperature for up to 2 weeks; do not refrigerate.
