Preheat the oven to 200 degrees F. Line two baking sheets with parchment paper and set aside.
On high speed, add the powdered sugar, one spoonful at a time. Add the peppermint extract. Keep beating until stiff, glossy peaks form.
Using a piping bag and open star tip, pipe swirls/roses onto the prepared baking sheets. You can also use two spoons to dollop the meringue onto the baking sheets.
Bake in the preheated oven for 3 hours, rotating the baking sheets halfway through. Turn off the heat, crack the oven door, and allow them to cool for 2 hours in the oven.
