In a blender, grind coolies into fine crumbs. Add the brown sugar, salt, and butter and combine well.
Press prepared crumbs into the bottom of a 9x13-inch pan. Bake at 350 degrees for 10 minutes.
Meanwhile, beat cream cheese, eggnog, flour, and sugar until smooth.
Add the egg white and mix well. Add the egg yolk and mix well.
Add the extract and nutmeg and blend to incorporate.
Pour the eggnog mixture over the baked crust and return to the oven.
Bake 25 minutes or until the center is set.
Allow to cool completely. Cut into squares and serve.
Diva’s Tip: Sprinkle a little cinnamon over the top of the bars before cutting into squares for an extra layer of yummy flavor!
