Add carrots, celery, spices, 1/2 cup baking mix and mix well.
Add broth, stir and heat over medium high until boiling.
Reduce heat to simmer and cover.
Cook for 20 minutes, or until carrots are soft, stirring occasionally.
In a separate bowl, combine the remaining 2 cups baking mix and milk.
Mix together with a fork. Drop by teaspoon dollops into the chicken mixture.
