In a mixer fitted with the paddle attachment, beat the cream cheese until creamy. Add the butter and beat until well incorporated. Add the light brown sugar and beat until fluffy. Add the powdered sugar 1 cup at a time, beating until well incorporated. Add the vanilla extract and beat until combined.

Preheat the oven to 300 degrees F. Spray a baking sheet with nonstick cooking spray.

Beat the egg white in a bowl until frothy; whisk 4 teaspoons water and the vanilla extract into the egg. Stir the sugar, cinnamon and salt into the egg mixture. Add the chopped pecans, stir to coat completely. Spread the pecans onto the baking sheet. Bake the pecans, stirring about every 20 minutes, until the coating forms a glaze, about 1 hour. Allow to cool on the baking sheet.
