Chocolate Chip Meringue Cookies

1. Preheat oven to 200 degrees F (95 degrees C). Line baking sheets with parchment paper.

2. In a large glass or metal bowl, whip egg whites until foamy using an electric mixer. Sprinkle in sugar a little at a time while continuing to whip. Keep whipping until the mixture becomes stiff and glossy.

3. Gently fold in chocolate chips and vanilla extract. Drop mixture by heaping tablespoons about 1 inch apart onto prepared baking sheets.

4. Bake for about 1 hour or until the meringues are lightly golden and dry to the touch. Turn the oven off and let the cookies sit in the oven for 1 hour.

5. Transfer cookies to a wire rack to cool completely. Store at room temperature in an airtight container.
