Make the cookie topping by combining the white sugar and cinnamon, and set aside.
In a mixing bowl, combine the flour, corn starch, baking powder, and baking soda, and set aside.
With your mixer, cream together the butter and brown sugar until light and fluffy. Add in the eggs and vanilla, and mix to combine.
Add the flour and brown sugar mixture and mix until combined; it will pull together into a cookie dough fairly quickly.
Using a tablespoon-sized cookie scoop, scoop balls of dough and roll them into smooth balls. Roll each ball in the cinnamon-sugar mixture to coat them.
Place the dough balls in the fridge and chill for at least 45 minutes to cut back on how much they spread out while baking.
Preheat your oven to 350℉. Arrange your dough balls on a parchment-lined baking sheet at least 2" apart to allow for spread. Bake for 11 minutes.
When baked, slide the parchment paper to a cooling rack to cool and set.
