Creating Meringue Ghost Cookies can be simple if you follow these steps:

1. Preheat the Oven: Set your oven to 200°F (93°C). Line a baking sheet with parchment paper.
2. Prepare the Mixing Bowl: Ensure your mixing bowl is clean and free from grease. This helps the egg whites whip properly.
3. Beat Egg Whites: In a large bowl, add the egg whites and pinch of salt. Beat with an electric mixer on medium speed until foamy.
4. Add Cream of Tartar: While continuing to beat, add the cream of tartar, which will help stabilize the egg whites.
5. Gradually Add Sugar: Slowly add in the granulated sugar, one tablespoon at a time, waiting until it dissolves before adding more. Continue to beat on high speed until stiff peaks form.
6. Mix in Vanilla: Once the mixture reaches stiff peaks, gently fold in the vanilla extract.
7. Pipe the Ghosts: Transfer the meringue to a piping bag fitted with a star tip. Pipe small dollops onto the prepared baking sheet, forming ghost shapes. Make sure to leave space between each cookie.
8. Add Chocolate Chips: Place mini chocolate chips on the piped meringue for the eyes before baking.
9. Bake: Place the baking sheet in the preheated oven and bake for 1 hour, or until the meringues are dry and crisp.
10. Cool: Turn off the oven and leave the cookies inside for an additional 10-15 minutes to cool completely before removing them from the baking sheet.

These steps will guide you in creating cute and spooky Meringue Ghost Cookies that are sure to impress.
