Mix oil and cottage cheese in a large bowl. Add remaining ingredients and mix until smooth with mixer or spoon.

Pour into greased nine- by 13-inch pan. Sprinkle with cinnamon sugar.

Bake at 350 degrees Fahrenheit for 45 minutes to one hour or until center is firm.

To serve hot, scoop onto plates; soufflé will be soft. Otherwise, let cool and cut into pieces.
