For the filling, combine together cream cheese, farmers cheese, egg and sugar in a bowl.
Set ingredients aside, as you work on the cookie dough.
In a bowl, combine butter, eggs, sugar and whisk it together until well combined.
To the whisked ingredients, add 2 cups of flour, baking powder and salt, whisk to combine.
Keep on adding a few cups of flour into the mixture, until all mixture is combined together.
Roll out the dough into 1/4 inch in thickness, cut out a round shape out of the dough, about 3 inches in diameter.
Place the cheese filling on one of the sides and fold the other side, covering half of the cheese filling.
Whisk egg in a bowl, I had no eggs on hand, so I used melted butter. Use it to brush the cookie tops and sprinkle them with sugar.
Bake it at 400F, for about 15 minutes or until the cookies are crispy.
