Preheat oven to 350°F. For the cookie dough, beat the butter and sugar together for 2 minutes. Add egg and egg yolks (save the egg whites for later). Mix in the vanilla.

Mix the flour, baking soda, and cream of tarter in a small bowl and then add it to the butter mixture. Add in chocolate chips if desired.

Shape the cookies into walnut sized balls and roll the cookie dough in granulated sugar, or brown sugar if you are using cinnamon cream cheese, and place on a greased cookie sheet. Take your ring finger and stick it into each cookie to form a small hole.

For the cheesecake mixture, soften the cream cheese. Then mix together the cream cheese of your choice, egg whites, and 1/2 cup sugar until well blended. Pour into the small holes in each cookie. Fill them to the top!

Bake for 13 to 17 minutes at 350°F until the edges are barely golden brown.
