01 - Preheat oven to 250°F. Line two baking sheets with parchment paper.
02 - In a clean, dry mixing bowl, beat the egg whites with cream of tartar and salt until soft peaks form.
03 - Gradually add brown sugar and granulated sugar, 1 tablespoon at a time, beating until stiff, glossy peaks form. Beat in vanilla extract.
04 - In a small skillet over medium heat, toast the chopped nuts with brown sugar and cinnamon until fragrant and just golden, 3–4 minutes. Let cool.
05 - Gently fold toasted nuts into the meringue.
06 - Spoon or pipe meringue onto prepared baking sheets in heaping, cloud-like dollops (about 2½-inch rounds), spacing apart.
07 - Bake for 1 hour, until crisp and dry but not browned. Turn off oven and let meringues cool inside with the door slightly ajar for 30 minutes.
08 - Dust with powdered sugar and sprinkle with optional gold stars before serving.
