In a very large mixing bowl, mix together the dry ingredients. Add in caraway seeds and set aside.
In another medium bowl, whisk eggs; whisk in sour cream. Combine this mixture to the dry ingredients and mix only until combined with wooden spoon.
Spray 9-inch spring-form pan with non-stick spray. Place batter in a pan; sift a little flour over the top making it easier to tap it down. Score an "X" with knife.
Bake for approximately 50 minutes.
