In a medium mixing bowl, beat together the liquid egg substitute and sugar with a hand mixer or whisk.
Add in the melted vegan butter and vanilla, Continue to mix.
Ise a sifter or mesh strainer to sift your dry ingredients into the wet mixture.
Using the hand mixer, mix until a thick batter forms.
Turn on your pizzelle maker and allow it to heat up. I usually use setting 3, but it may vary depending on the pizzelle maker being used.
Scoop one tablespoon of the batter into the center of each pizzelle mold and close the press. Allow them to cook for 30-60 seconds, depending on how crispy you want them.
Remove them from the press gently and place them on a cooling rack to cool completely.
Repeat until all the batter is used.
When the cookies are fully cooled, dust each with powdered sugar if desired.
