These two-ingredient ghost meringue cookies are the ultimate last-minute Halloween trick that feels like a treat. Made with just egg whites and sugar, they are light, airy, and naturally gluten-free.
Do not make meringues on a humid day. Ensure bowls and utensils are completely clean and dry. For best results, use eggs that are a few days old and at room temperature. Store in an airtight container at room temperature for up to 2-3 weeks.
