These crispy ghost meringue cookies are a simple, spooky, and delicious Halloween treat. Made with just egg whites, sugar, and cream of tartar, they are naturally gluten-free, light, and shatteringly crisp.
Ensure all equipment is completely grease-free. Use room temperature egg whites for better volume. Do not open the oven door frequently during baking. Store in an airtight container away from humidity. For vegan version, substitute egg whites with aquafaba (3 tbsp per egg white).
