Vanilla Meringue Cookies

Step 1
Preheat the oven to 225 degrees F (110 degrees C). Line a large baking sheet with parchment paper.

Step 2
Place egg whites and cream of tartar into a large bowl; beat using an electric mixer at medium speed until soft peaks form. Increase speed to high and add sugar 1 tablespoon at a time while mixing until stiff peaks form. Scrape seeds from vanilla bean into the bowl and add vanilla extract; beat just until blended.

Step 3
Spoon batter into a pastry bag and pipe mounds onto the prepared baking sheet.

Step 4
Bake in the preheated oven until set, about 1 1/2 hours. Turn oven off; let cookies cool in the closed oven for 1 1/2 hours. Remove cookies carefully from paper.
