In a small bowl, stir together the sugar and cinnamon for Topping. Set aside.
To make cookie dough, stir together dry ingredients. In the bowl of a stand mixer, cream the butter. Add the sugar and continue to mix. Add eggs, cornsyrup, and vanilla, mix thoroughly. Add dry ingredients and mix until well blended. If dough is sticky and too hard to handle, you can refrigerate it for an hour. OR using a cookie dough scoop, scoop large tablespoons of the dough, and one ball at a time, drop the dough into the bowl of cinnamon/sugar. Roll the ball around to coat.
Place cinnamon sugar coated cookies on an ungreased cookie sheet lined with parchament paper and bake in a preheated 375 degree oven for 10-12 minutes until the cookies have puffed up and the surface is slightly cracked looking.
Let the cookies cool on the cookie sheet a few mintues before moving them to a wire rack to cool completely.
