In a large bowl, cream together the butter and brown sugar until smooth. Beat in the eggs one at a time, stir in the crushed pineapple, carrots and raisins. Combine the flour, baking powder, baking soda, salt and cinnamon; stir into the carrot mixture. Mix in the walnuts if desired. Drop by rounded spoonfuls onto the prepared cookie sheets.
