Preheat the oven to 200°F (93°C) and line a baking sheet with parchment paper.
In a clean mixing bowl, beat egg whites until frothy. Add cream of tartar and salt; beat until soft peaks form.
Gradually add sugar, one tablespoon at a time, while beating until stiff, glossy peaks form.
Add Jell-O powder and vanilla extract. Beat until fully combined and color is evenly distributed.
Transfer mixture to a piping bag fitted with a star tip or use a zip-top bag with a corner snipped off.
Pipe small meringue kisses onto the baking sheet, spacing them about 1 inch apart.
Bake for 60 minutes. Turn off oven and let cookies sit inside for another 60 minutes to dry completely.
Once cooled, store in an airtight container at room temperature.
Notes
Make sure your bowl is grease-free before beating egg whites for best volume.If you’re piping multiple colors, divide meringue into batches and mix different Jell-O flavors separately.
