In a food processor grind the cereal. Spray the bottom and sides of a 4" springform pan with nonfat baking spray. Sprinkle on the bottom of the pan.
In a bowl beat all ingredients until smooth. Pour filling into the prepared pan. Bake at 350° for 50 minutes until a knife inserted in the center comes out clean (check at 40 minutes). Let cool, then refrigerate for at least 2 - 3 hours. Remove from springform pan and serve with berries if desired.
