In separate bowl beat eggs, sugars, vanilla and eggs until smooth.
Gradually add dry ingredients until dough is completely blended. Refrigerate dough for approximately 1 hour or until dough is completely chilled and stiff.
Remove marshmallows from freezer. Take dough out of frig. Roll a healthy tablespoon of dough into a ball. Press your thumb into the middle of the ball, making a hollow for the marshmallow to wait. Move dough over and around marshmallow, enclosing the frozen marshmallow. Roll each ball in a bowl of sugar to coat entire ball. Place on pans and bake for 8- 10 minutes. Let sit on pan until cooled or cookie falls apart if moved too soon.
