These ghost meringue cookies are a happy accident turned into the most-requested Halloween treat. Quick, easy, and absolutely adorable, they require only three simple ingredients and come together in about 15 minutes of active prep time.
Humidity is the enemy of meringue — make these on a dry day if possible. Ensure your bowl is completely clean and dry with no trace of grease or egg yolk. For best results, use room temperature egg whites. If you don’t have cream of tartar, substitute ½ teaspoon of lemon juice or white vinegar. These cookies store well in an airtight container at room temperature for up to 2 weeks. They actually taste better the next day.
