3 1/2 tablespoons fresh lemon juice (or 2 lemons worth)
1/4 teaspoon baking powder
1 large egg
1 large egg white (from the carton)
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 with a piece of foil 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 splenda and remaining ingredients, and process until well-blended.
Pour filling over crust. Bake at 350° for 25 30 minutes or until set (the edges will get lightly browned), and cool.
