Preheat oven to 350°.
To prepare crust, place first 4 ingredients in a large bowl, and beat with a mixer at medium speed until smooth. Lightly spoon 1 cup flour into a dry measuring cup, and level with a knife. Add 1 cup flour to butter mixture, and beat at low speed until well-blended. Press crust into an 8-inch square baking pan coated with cooking spray. Bake at 350° for 20 minutes.
To prepare filling, place cottage cheese in a food processor; process 2 minutes or until smooth, scraping sides of bowl once. Add 1 cup granulated sugar and remaining ingredients, and process until well-blended. Pour filling over crust. Bake at 350° for 25 minutes or until set (the edges will get lightly browned), and cool. Cover and chill for 8 hours.
