Preheat the oven to 400 degrees (F).
Line 2 baking sheets with parchment paper.
Mix sugar, butter, eggs, and vanilla extract.
Mix flour, baking powder, and salt in another bowl and stir into the butter/sugar mixture.
In a separate small bowl, mix the sugar and cinnamon.
Scoop out the dough into large balls and roll them in the cinnamon sugar.
Place on the prepared baking sheets.
Bake for 10 minutes or until golden brown - do not overcook.
Enjoy!
If the dough seems too sticky to roll into balls, refrigerate for 30 minutes.
