4 egg whites at room temperature
1 cup white granulated sugar
1/4 tsp cream of tartar
1/2 tsp vanilla extract
Holiday sprinkles to decorate
Preheat oven to 225F. Line 2 baking sheets with parchment paper. Beat egg whites with an electric mixer until frothy. Add cream of tartar. Beat until soft peaks form. Increase speed to medium high. Slowly add sugar 1 tbsp at a time until dissolved and stiff peaks form. Beat in vanilla. Fill a piping bag with meringue. Use a star tip. Pipe trees, starting from the middle, pipe a circle and then 2 more, finishing in the middle on top. Decorate your trees. Bake cookies for 1 1/2 to 2 hours. Check them often. Turn off oven, open door and let them cool inside. Store meringue cookies in an airtight container away from any heat or moisture.
