Grease baking sheets.
Beat eggs into cooled mixture one at a time.
Pipe or spoon mixture in small balls onto greased baking sheets.
Bake about 20 minutes or until crisp and golden brown.

Cut puffs in half; cool on a rack.
To make filling, put cream cheese, paprika, celery salt and chives into a small bowl.
Beat in enough milk to give a piping consistency.
Put filling into a pastry bag fitted with a fluted nozzle.
