Heat Pizzelle iron while you prepare the batter. If it needs cleaning from prior use, a vegetable brush works great!
Using a stand mixer, crack eggs into the bowl and whisk until fluffy. Add sugar, melted butter, and anise extract, then mix to combine. Sift flour, baking powder, and salt into the bowl and mix until the batter is smooth.
Spray Pizzelle maker with non-tick cooking spray, then place one tablespoon of batter in the center of each circle. Close lid and latch.
Cook until hardly any steam is being produced, or the light turns green. Depending on the setting and your iron, this can take anywhere from 30 seconds to 1 minute.
Use a fork or a thin spatula to transfer the Pizzelle onto a cooling rack. Makes sure they lay perfectly flat, as they will harden in that position. Continue until the batter is used up.
Sprinkle cooled cookies with powdered sugar.
Store cookies in your favorite jar or tin for longer storage. This will help to retain their crispy textures.
