1. Preheat oven to 350 degrees.

2. Grease a baking dish with margarine (I usually use two square pans). Spread 1 pkg of crescent rolls onto the bottom of the pan(s). Mix the cream cheese, egg yolk, 1 cup sugar and vanilla extract until creamy. Pour onto roll in pan. Spread 2nd pkg of rolls onto cream cheese mix.

3. Beat egg white until foamy. Spread egg white onto rolls, sprinkle with 1/4 cup sugar and sprinkle walnuts on top.

4. Bake at 350 for 30 minutes or more (check after 30 minutes--with a toothpick). Crescent rolls should be evenly brown.

5. Chill and cut into squares.
