Preheat your oven to 375 degrees.
Whip the butter and first sugar in a stand mixer until light and fluffy and then add the eggs, one at a time. Add the vanilla and corn syrup and continue to beat until the batter is smooth.
Meanwhile, in a separate bowl whisk together the flour, baking powder, soda and salt. Add to the butter and egg mixture and continue mixing until well combined.
Whisk the remaining white sugar and cinnamon together. Scoop up some of the dough with a spoon then using your hands roll it into a ball. Roll balls in the cinnamon sugar to coat then place on a parchment or silicon lined baking sheet, leaving about 2 inches between cookies. Lightly flatten the balls with your fingertips.
Bake for 12 minutes.
