Combine butter and sugar with a wire whisk. Combine eggs and milk and whisk into sugar mixture. Combine  flour and baking power and gradually whisk into mixture.  Whisk in anise and vanilla extract then anise seed. 

Drop about 2 to 3 teaspoonfuls onto preheated pizzelle maker.

Close pizzelle maker and cook 30 seconds to 2 minutes or until golden.  Use a fork to remove pizzelle to a wire rack and let cool.  

Repeat until you've used up the batter.  

Pizzelle makers vary so it may take a little adjustment to get your timing just right.  Even with the same maker the timing will vary as the maker cycles.  Sometimes pizzelles are done in 30 seconds, sometime 2 minutes.  You really just have to watch them carefully.
