Preheat oven to 350°. Line an 8-inch square metal pan with foil and spray foil with cooking spray or line it with nonstick foil (or parchment if that's what you prefer).
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 the 1 cup flour to the butter mixture, and beat at low speed until well-blended. Press crust into prepared pan and bake at 350° for 20 minutes. Let cool while you make the filling.
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.
Notes
To make the crust in the food processor. process the softened butter, brown sugar, nutmeg and salt until creamy. Add the flour and pulse until evenly blended -- do not overprocess, just pulse enough so that the butter is evenly dispersed. Dump into the pan and press evenly. Bake for 20 minutes.
